The document discusses RESTful web services and how to build them using the Mendix platform. Key points include:
1. The Mendix REST module allows consuming external REST APIs, publishing microflows and data models as REST endpoints, and synchronizing data between Mendix applications in real-time.
2. Core aspects of RESTful design include using HTTP verbs for CRUD operations, representing resources as JSON or XML, and making services stateless and cacheable through the use of URIs and links.
3. The Mendix REST module provides actions and configuration for publishing microflows and data models as REST endpoints, securing services, and serializing data to and from JSON for requests and responses.
An overview of Azure API Management, common use cases, and how it helps organizations to govern, publish, secure, analyze, and manage APIs for internal and external consumption whether their running in the cloud or on-prem.
The document discusses API security patterns and practices. It covers topics like API gateways, authentication methods like basic authentication and OAuth 2.0, authorization with XACML policies, and securing APIs through measures like TLS, JWTs, and throttling to ensure authentication, authorization, confidentiality, integrity, non-repudiation, and availability. Key points covered include the gateway pattern, direct vs brokered authentication, JSON web tokens for self-contained access tokens, and combining OAuth and XACML for fine-grained access control.
This document discusses hybrid mobile apps that can be built using Angular and the Ionic framework. Hybrid apps allow developers to build apps that can run on multiple platforms using web technologies like HTML, CSS, and JavaScript. The Ionic framework builds on Apache Cordova to provide access to native device capabilities and solve issues with supporting multiple screen resolutions. Developers can use Angular for features like data binding and services, and Ionic adds capabilities specific to building mobile apps like routing and UI components optimized for touch. The document provides instructions for setting up Ionic and Cordova and creating a basic sidemenu template project to get started developing hybrid mobile apps.
Threat protection and application access controls are key security mechanisms that protect APIs when exposed to internal or external users and developers.
In this technical deep-dive webcast, Apigee's security team, led by Subra Kumaraswamy, will discuss API threats and the protection mechanisms that every API and app developer must implement for safe and secure API management.
This webcast will cover:
- the API threat model
- how to design and implement appropriate guardrails for API security using build-in policies and configuration
- a demo of Apigee Edge threat protection features, including TLS encryption, XML/JSON/SQL injection attacks, and rate limiting
Whether you're an IT security architect or an API or app developer, this webcast will help you understand secure API management.

We start with an introduction to what Apache Camel is, and how you can use Camel to make integration much easier. Allowing you to focus on your business logic, rather than low level messaging protocols, and transports. You will also hear what other features Camel provides out of the box, which can make integration much easier for you.
We look into web console tooling that allows you to get insight into your running Apache Camel applications, which has among others visual route diagrams with tracing/debugging and profiling capabilities. In addition to the web tooling we will also show you other tools in the making.
The security of an application is a continuous struggle between solid proactive controls and quality in SDLC versus human weakness and resource restrictions. As the pentester's experience confirms, unfortunatelly even in high-risk (e.g. banking) applications, developed by recognized vendors, the latter often wins - and we end up with critical vulnerabilities.
One of the primary reasons is lack of mechanisms enforcing secure code by default, as opposed to manual adding security per each function. Whenever the secure configuration is not default, there will almost inevitably be bugs, especially in complex systems.
I will pinpoint what should be taken into consideration in the architecture and design process of the application. I will show solutions that impose security in ways difficult to circumvent unintentionally by creative developers. I will also share with the audience the pentester's (=attacker's) perspective, and a few clever tricks that made the pentest
(=attack) painful, or just rendered the scenarios irrelevant.

REST Service Authetication with TLS & JWTsJon Todd
Many companies are adopting micro-services architectures to promote decoupling and separation of concerns in their applications. One inherent challenge with breaking applications up into small services is that now each service needs to deal with authenticating and authorizing requests made to it. We present a clean way to solve this problem Json Web Tokens (JWT) and TLS using Java.
DevSum: Azure AD B2C Application security made easySjoukje Zaal
This document summarizes a presentation about Azure Active Directory B2C (Azure AD B2C). It discusses what Azure AD B2C is, its key benefits including being highly available, scalable, secure, and flexible. It covers capabilities like default and social identity providers, single sign-on, and multi-factor authentication. It also outlines demo sections covering registering an application, creating user flows, configuring identity providers, customizing the UI, and enabling multi-factor authentication.
Azure AD Connect allows syncing of local Active Directory accounts to Azure Active Directory. It requires an Azure AD global administrator account, an enterprise administrator account for the local AD, a SQL Server database, and meeting server and hardware requirements. The setup process involves creating a global administrator account, installing Azure AD Connect, and configuring it for initial or subsequent synchronization of users and groups between the local and cloud directories.
A presentation on System for Cross-domain Identity Management (SCIM) formerly Simple Cloud Identity Management presented at the Cloud Identity Summit (CIS) 2012 by Travis Spencer, CEO of Twobo Technologies, a consulting firm specializing in Identity and Access Management (IAM), cloud security, and mobile security
IdP, SAML, OAuth are new acronyms for identity in the cloud. SAML is used for federated authentication between an identity provider (IdP) like Active Directory and a service provider (SP) like Office 365. The IdP authenticates the user and sends a SAML token with claims to the SP. OAuth streamlines authentication for mobile by issuing short-lived access tokens instead of passing full credentials or SAML assertions between each service. It allows authorization without passwords and tokens can be revoked, reducing risks of compromised apps. Office 365 uses Azure Active Directory as an IdP with SAML or OAuth to authenticate users from an on-premises Active Directory via federation or synchronization.

J2EE : Java servlet and its types, environmentjoearunraja2
The server-side extensions are nothing but the technologies that are used to create dynamic Web pages. Actually, to provide the facility of dynamic Web pages, Web pages need a container or Web server. To meet this requirement, independent Web server providers offer some proprietary solutions in the form of APIs (Application Programming Interface).
These APIs allow us to build programs that can run with a Web server. In this case, Java Servlet is also one of the component APIs of Java Platform Enterprise Edition (nowadays known as – ‘Jakarta EE’) which sets standards for creating dynamic Web applications in Java.
Today we all are aware of the need to create dynamic web pages i.e. the ones that can change the site contents according to the time or can generate the content according to the request received by the client. If you like coding in Java, then you will be happy to know that using Java there also exists a way to generate dynamic web pages and that way is Java Servlet. But before we move forward with our topic let’s first understand the need for server-side extensions.
Servlets are the Java programs that run on the Java-enabled web server or application server. They are used to handle the request obtained from the web server, process the request, produce the response, and then send a response back to the web server. Servlet is faster than CGI as it doesn’t involve the creation of a new process for every new request received.
Servlets, as written in Java, are platform independent.
Removes the overhead of creating a new process for each request as Servlet doesn’t run in a separate process. There is only a single instance that handles all requests concurrently. This also saves the memory and allows a Servlet to easily manage the client state.
It is a server-side component, so Servlet inherits the security provided by the Web server.
The API designed for Java Servlet automatically acquires the advantages of the Java platforms such as platform-independent and portability. In addition, it obviously can use the wide range of APIs created on Java platforms such as JDBC to access the database.
Many Web servers that are suitable for personal use or low-traffic websites are offered for free or at extremely cheap costs eg. Java servlet. However, the majority of commercial-grade Web servers are rather expensive, with the notable exception of Apache, which is free.
The Servlet Container
Servlet container, also known as Servlet engine, is an integrated set of objects that provide a run time environment for Java Servlet components. In simple words, it is a system that manages Java Servlet components on top of the Web server to handle the Web client requests.
Services provided by the Servlet container:
Network Services: Loads a Servlet class. The loading may be from a local file system, a remote file system or other network services. The Servlet container provides the network services over which the request and response are sent.

The document provides details of the different OAuth grant types and threats related to OAuth like lack of TLS enforcement, CSRF attacks, improper storage of sensitive data, and overly scoped access tokens.
The document discusses various aspects of networks, servers, and websockets. It defines clients as web browsers that receive pages from webservers. Servers return HTML and other content like images. A web server delivers static content while an application server provides dynamic content by transforming data with business logic. Common free and open source web servers and application servers are also mentioned. The document then provides more details on web servers, including definitions, visual diagrams, examples of static vs dynamic servers, and commonly used free web server options. Potential HTTP error codes from 100-511 are also summarized at different levels.
The document discusses various aspects of networks, servers, and websockets. It defines clients and servers, explaining that clients request pages from servers. It distinguishes between web servers, which deliver static content, and application servers, which deliver dynamic content by connecting to databases. Common free and open source web and application servers are also listed. The document then focuses on web servers, defining them as software and hardware that uses HTTP and other protocols to respond to client requests over the web. Potential errors servers may return are categorized into classes based on their numeric codes.
The document provides an overview of REST methodologies and the Richardson Maturity Model. It discusses the four levels of the Richardson Maturity Model - from level 0 where only one entry point and method are used, to level 3 where hypermedia controls and content negotiation are implemented. The bulk of the document focuses on best practices for designing RESTful APIs, including URI design, HTTP verbs, status codes, conditional requests, caching, security, and versioning. It concludes with references for further reading.
This document discusses various protocols for web connectivity, including communication gateways, HTTP, SOAP, REST, and WebSockets. Communication gateways allow different protocols to be used at each end of a connection. HTTP is the most widely used application layer protocol and uses request/response methods. SOAP is an XML-based protocol for exchanging objects between applications. REST is a simpler alternative to SOAP that uses HTTP methods like GET, POST, PUT and DELETE. WebSockets enable bidirectional communication over a single TCP connection.
Windows 8 apps can access data from services in several ways:
- They can call ASMX, WCF, and REST services asynchronously using HttpClient and retrieve responses.
- They can access oData services using the oData client library.
- They can retrieve RSS feeds using SyndicationClient and parse the responses.
- They can perform background transfers using BackgroundDownloader.
- They can update tiles periodically by polling a service and setting updates.
This document provides an overview of Representational State Transfer (REST) theory and the Java API for RESTful Web Services (JAX-RS). It begins with an agenda that outlines REST principles, anti-patterns, and patterns that will be covered, as well as an introduction to JAX-RS and examples of its code. The document then discusses the core REST principles of addressability, connectedness, uniform interface, representations, and statelessness. It also identifies common REST anti-patterns and provides examples of good REST patterns and practices. Finally, it introduces JAX-RS as an annotation-driven API that helps developers build RESTful web services in compliance with REST principles and J2EE integration.

AJAX allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes. This means that it is possible to update parts of a web page, without reloading the whole page. AJAX uses a combination of XMLHttpRequest objects, JavaScript, HTML and CSS. The XMLHttpRequest object is used to request data from the server after the page has loaded.
A browser allows users to view and interact with resources on the World Wide Web. It displays HTML pages and other web content by making HTTP requests and rendering the responses. Key components of a browser include a user interface, layout engine, rendering engine, JavaScript interpreter, and networking components. When a user enters a URL, the browser looks up the IP address and sends HTTP requests to retrieve and display the requested content, including linked resources. Common browser features include back/forward buttons, an address bar, and the ability to view page source. Browsers support privacy/security functions and web standards.
Introduce the Java Enterprise (J2EE) model
Present the Hypertext Markup Language (HTML) tags
Present the Hypertext Transmission Protocol (HTTP)
Define an HTTP client request, server response, and HTTP request methods
The document provides an overview of REST API basics and compares traditional web applications to RESTful APIs. Some key points:
- Traditional web apps use HTML and HTTP, replacing entire pages on each request, while RESTful APIs focus on resources and use HTTP methods to perform CRUD operations.
- REST (Representational State Transfer) is an architectural style using URIs to identify resources and HTTP methods to operate on them. It advocates a stateless, cacheable, layered system of web services.
- Examples show how HTTP methods like GET, POST, PUT, PATCH, and DELETE map to CRUD operations on resources, with content types specifying response formats. Status codes indicate success or failure.
The document provides an overview of servlets, including:
- Servlets allow generating dynamic web content and communication with other server resources like databases.
- The servlet lifecycle includes initialization, handling requests, and destruction.
- Servlets extend HttpServlet to handle HTTP requests and responses, overriding methods like doGet() and doPost().
- The web container manages servlets, providing threading and other services.
The document discusses testing REST APIs using Java. It covers creating test cases to test API functionality, parameters, and expected results. It also discusses best practices for organizing test cases and ensuring complete test coverage. The document then describes how to perform automated testing of APIs using Java tools like POJOs, serialization/deserialization, Rest-Assured, and assertion libraries. It provides details on HTTP methods like GET, POST, PUT, DELETE and important HTTP headers.

Microservice Teams - How the cloud changes the way we workSven Peters
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.

Mendix rest services
1. By Acellam Guy
@mistaguy
1. Consume JSON REST based services
2. Publish data or microflows through REST API's
3. (Real time) Synchronization of data between Mendix
applications
2. By Acellam Guy
@mistaguy
REST ?
• REST stands for Representational StateTransfer
• BuildWeb services that are lightweight, maintainable, and scalable
• A service based on REST is called a RESTful service
• REST is not dependent on any protocol
3. By Acellam Guy
@mistaguy
Features of a RESTful webservice
• Representations
• Messages
• URIs
• Uniform interface
• Stateless
• Links between resources
• Caching
4. By Acellam Guy
@mistaguy
Representations
• Resources and how to provide access to these resources
• Format of representation JSON,XML ,etc
• Both client and server should be able to comprehend format of
representation
• A representation should be able to completely represent a resource
• The representation should be capable of linking resources to each other
6. By Acellam Guy
@mistaguy
URI
• The job of a URI is to identify a resource or a collection of resources
• The actual operation is determined by an HTTP verb
Eg.
http://localhost:8080/Persons/1
This URL has following
format: Protocol://ServiceName/ResourceType/ResourceID
7. By Acellam Guy
@mistaguy
Uniform Interface
• Systems should have a uniform interface. HTTP 1.1 provides a set of
methods, called verbs, for this purpose
Method Operation performed on server Quality
GET Read a resource. Safe
PUT Insert a new resource or update if the resource already exists. Idempotent
POST Insert a new resource. Also can be used to update an existing resource. N/A
DELETE Delete a resource . Idempotent
OPTIONS List the allowed operations on a resource. Safe
HEAD Return only the response headers and no response body. Safe
8. By Acellam Guy
@mistaguy
Statelessness
• Does not maintain the application state for any client
• A request cannot be dependent on a past request and a service treats each
request independently
A stateless design looks like so:
Request1: GET http://MyService/Persons/1 HTTP/1.1
Request2: GET http://MyService/Persons/2 HTTP/1.1
Each of these requests can be treated separately.
A stateful design, on the other hand, looks like so:
Request1: GET http://MyService/Persons/1 HTTP/1.1
Request2: GET http://MyService/NextPerson HTTP/1.1
9. By Acellam Guy
@mistaguy
Links Between Resources
• A resource representation can contain links to other resources like an HTML
page contains links to other pages
• The user does not need a map before coming to a website
• A service can be (and should be) designed in the same way
10. By Acellam Guy
@mistaguy
Caching
• Caching is the concept of storing the generated results and using the stored
results instead of generating them repeatedly if the same request arrives in
the near future
11. By Acellam Guy
@mistaguy
Mendix REST Module
• Mendix 4.4.4+ or Mendix 5.3.1+
• If you want to publish REST services or use the data synchronization features,
addIVK_OpenServiceOverview to your main navigation.
add StartPublishServices to the startup sequence of your application
• map your administrative project role to the Administratorrole in the RestServices
for admin features
• The 'rest/' request handler needs to be opened if running in the Mendix Standard
Cloud (or on premise).
• strongly recommended to not use the default HSQLDB engine if you want to
publish RestServices while running locally
12. By Acellam Guy
@mistaguy
Consuming REST services
• The operations in the 'Consume' folder of the module provide the necessary
tools to invoke data
• The core of all these operations is the java action request
13. By Acellam Guy
@mistaguy
The REQUEST java action
• Request performs an HTTP request and provides the means to both send data and receive
data over HTTP
• Parameters
• Method : HTTP 1.1 verbs
• URL : location of the service
• optRequestData : provides parameters
• optResponseData : provides response
• ResquestResult : HTTP response
• sendWithFormEncoding
14. By Acellam Guy
@mistaguy
RequestResult Object
• contains the meta information of a response
• Response code
• Etag
• ResponseBody :the full and raw response body of the request.
15. By Acellam Guy
@mistaguy
Sending Request Headers
• addHeaderToNextRequest : will add a header to the next (and only the next)
request that will be made by the current microflow
17. By Acellam Guy
@mistaguy
Consume Methods
• get :Tries to retrieve an object from the provided resourceURL
• get2: Similar to get, but also accepts a requestData parameter
• ?q=Rest%20Services‘
• getCollection : gets a list of objects. JSON array
• getCollectionAsync
• post
• delete
• put
• getRequestConsumerError
19. By Acellam Guy
@mistaguy
Publishing webservices
• Publishing operations, based on a single microflow.
• Publishing a part of your data model, and providing a typical rest based API
to retrieve, update, delete, create and even real-time sync data.
• PLEASE NOTETHATTO BE ABLETO PUBLISH ANY SERVICE,THE
MICROFLOW STARTPUBLISHSERVICES SHOULD BE CALLED DURING
STARTUP OFTHE APP!
• Accessible via http://apphost/rest/yourservice
20. By Acellam Guy
@mistaguy
Publishing a microflow
• similar to publishing a webservice
• instead of SOAP it uses JSON based messages
• Has a single transient object as argument.
• Each field in this transient object is considered a parameter (from HTTP perspective)
• The return type of the microflow should be a transient object or a String or a filedocument
• Publish by calling CreateMicroflowService with the microflow that provides the
implementation
21. By Acellam Guy
@mistaguy
Microflow with template path
• Allows for constructing more complex URLs, from which values are parsed
Eg.
groups/{groupId}/users/{userId}
http://myapp.com/rest/groups/123/users/John
22. By Acellam Guy
@mistaguy
Publishing a data service
• JSON based API to list, retrieve, create, update, delete and track objects in
your database
• Documentation is generated automatically
24. By Acellam Guy
@mistaguy
How the data service works
• persistent entity in your database acting as data source
• transient object that acts as view object of your data
• Publish Microflow has the responsibility of converting source objects into
view objects
• Update Microflow is responsible for transforming a view as provided by
some consumer into real data in your database
• Each source object should be uniquely identifiable by a single key attribute
26. By Acellam Guy
@mistaguy
Creating a new webservice
• Add IVK_OpenServiceOverview to your navigation and create a new
Published Service after starting your app
• best practice is to use the GetOrCreateDataService microflow in the
startup microflow to create your service configuration
27. By Acellam Guy
@mistaguy
Configuring the service
• Its done on the form or the create service microflow
• Core configuration are:
• Name
• Description
• Source Entity
• Source Key Attribute
• Source Constraint : xpath
• Authentication Role
• On Publish Microflow
• On Update Microflow
• On Delete Microflow
28. By Acellam Guy
@mistaguy
Features
• Enable GET : HTTP GET
• Enable Listing : HTTP GET
• Enable Update : HTTP POST or PUT
• Enable Create : HTTP POST
• Enable Delete : HTTP DELETE
• Enable Change Log: caching
• Enable StrictVersion:
29. By Acellam Guy
@mistaguy
Securing Published webservice
• *
• Rolename
• Module.Microflowname : Authentication details found in the header eg key
30. By Acellam Guy
@mistaguy
JSON Serialization
• Converts transient object to JSON
• Nearest json type
• For each owned reference that points to a transient object, another
key/value pair is added to the object
• For each owned referenceset that points to a transient object, the same
approach is taken, except that the value is an array ([])
• Manual serialization process by use of serializeObjectToJson java action.
32. By Acellam Guy
@mistaguy
JSON Desrialization
• an be triggered manually by calling deserializeJsonToObject
• Converts the json from the consumer into a mendix transient object
• key/value pair for primitive attribute in transient object
• If the primitive is of type string, but the member with the same name in the
transient object is a reference, the process assumes that the string value represents
an url.
• If the member in the target object is a reference, and the value is a JSON object, a
new object of the child type of the reference is instantiated
• If target is reference set and JSON is array then reference set is created

Editor's Notes
REST has become the default for most Web and mobile apps, it's imperative to have the basics at your fingertips.
Every major development language now includes frameworks for building RESTful Web services
Almost every RESTful service uses HTTP as its underlying protocol. In this article
Use plural nouns for naming your resources.
Avoid using spaces as they create confusion. Use an _ (underscore) or – (hyphen) instead.
A URI is case insensitive. I use camel case in my URIs for better clarity. You can use all lower-case URIs.
You can have your own conventions, but stay consistent throughout the service. Make sure your clients are aware of this convention. It becomes easier for your clients to construct the URIs programmatically if they are aware of the resource hierarchy and the URI convention you follow.
A cool URI never changes; so give some thought before deciding on the URIs for your service. If you need to change the location of a resource, do not discard the old URI. If a request comes for the old URI, use status code 300 and redirect the client to the new location.
Avoid verbs for your resource names until your resource is actually an operation or a process. Verbs are more suitable for the names of operations. For example, a RESTful service should not have the URIs http://MyService/FetcthPerson/1 orhttp://MyService/DeletePerson?id=1.
so that your internal data structure is not directly published to the outside. This allows for better maintainability and it guarantees that you can pre- or post-process your data when required.
It will search for the first source object in your database which key value equals the identifier. If found, this object will be converted by thePublish Microflow into a view object. This view object will be serialized to JSON (or HTML or XML) and returned to the consumer.
