JAX-WS is the replacement and next generation to JAX-RPC and makes web services development much easier using annotations and much less configuration. JAX-WS is useful for people building webservices/SOA based infrastructure as JAX-WS makes the web service development much easier and is a big gain for developer productivity.
The session uses a web service for temperature conversion example to build both the client side and Server side artifacts. Also on the server side both Servlet based and EJB3.0 based web service development will be demonstrated. JAXB concepts will be used to demonstrate the examples.
The session uses Eclipse Ganymede and Jboss 5.0. However JAX-WS being the standard, the code will smoothly work on any JavaEE based compliant servers.
Overview of web services, SOAP, WSDL and UDDI.
A web service provides a defined set of functionality on a machine-processable interface.
The web service interface is described in a formal language like WSDL that allows creating code to access the service thus simplifying web service consumer (client) and provider (server) development.
In big web services, the interface is typically described in WSDL while the access to the service makes use of the SOAP message protocol.
SOAP has its roots in remote object access but is now a general message based and asynchronous transport mechanism.
SOAP is typically carried in HTTP (HyperText Transmission Protocol), but other message based protocols like SMTP (Email) or plain TCP could be used as well.
WSDL provides a formalized description of an interface that is coarsely separated in an abstract service interface definition containing operations and data types, a transport binding that describes how the web service is accessed and finally a description of the location (address) under which a web service is accessible.
UDDI (Universal Description and Discovery Protocol) was meant to become the standard protocol for some kind of a public yellow pages where publicly accessible web services would be listed. Lack of industry interest, however, prevented UDDI to gain widespread use.

The slides provide a major overview on SOAP protocol, and demonstrates a working example that uses SOAP for RPC. It uses WCF/visual studio and Apache Axis for the implementation.
XML, which stands for eXtensible Markup Language, is rapidly emerging as the preferred technology to exhange structured data between systems. Wikipedia defines XML as a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. It is defined by the W3C's XML 1.0 Specification and by several other related specifications, all of which are free open standards. This presentation discusses how XML documents are exchanged in an SOA environment using SOAP and the importance of WSDL.

A quick overview on REST : what it is and what it is not. REST has strict contraints and many internet Apis are not so REST. It’s also very popular today because RESTfull services can be consumed easily by any client or device. Soap is also still valid in a few circomstaces. It has never been so easy to create Rest-like services in .net since asp.net Web Api.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule

Intro To Web and Web Services (REST Series 01)
1. INTRO TO WEB AND
WEB SERVICES
Overview of HTTP, Servlets and SOAP Web Services
Presenter: Heartin Jacob Kanikathottu
(www.codingarchitect.com, www.javajee.com)
2. TOPICS
• Revision of basic web application concepts.
• Revision of HTTP, Servlets and Servers.
• Introduction to Web Services and Overview of SOAP Web Services.
• Overview of REST Web Services and Differences with SOAP Web Services.
• Java support for Web Services – JAX-WS and JAX-RS.
• Resources and References
3. REVISION OF BASIC WEB APPLICATION
CONCEPTS
• Internet Protocols
• TCP (Transmission Control Protocol), IP (Internet Protocol), UDP (User Datagram Protocol),
HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol) and SMTP (Simple Mail
Transfer Protocol).
• URI, URL and URN
• Uniform resource identifier (URI) is a string of characters used to identify a name of a
resource.
• Concrete forms of URI: uniform resource locator (URL) and uniform resource name (URN).
• Client side technologies: HTML, JavaScript and CSS
• Web applications vs. web services
• Human users vs. other systems as client.
4. REVISION OF HYPER TEXT TRANSFER
PROTOCOL (HTTP)
• HTTP is a synchronous request-response application network protocol.
• The seven HTTP methods are GET, POST, HEAD, OPTIONS, TRACE, PUT, DELETE.
• Idempotent request
• An idempotent request is meant to have the same result how many times it is executed.
• GET, PUT, DELETE are supposed to be idempotent, whereas POST is not.
• HTTP Status Codes
• Status of a request sent through the use of status codes, which are sent back along with the
response.
• There are five classes of status codes: Informational (1XX), Successful (2XX), Redirection
(3XX), Client Error (4XX), Server Error (5XX).
5. REVISION OF SERVLETS AND SERVERS
• Servlets are java components that can respond to an HTTP request.
• There are methods in Java Servlets corresponding to each of the HTTP methods.
• The seven HTTP methods map on to seven servlet methods of the same name with a “do”
in front (e.g., POST maps on to doPost()).
• The doXXX() methods receive two objects as parameters—the first representing the
HTTP request and the second the HTTP response.
• Java Web Servers
• Web container for servlets and JSPs. E.g. Tomcat
• Application server has EJB and Web Container, and more. E.g. Glassfish, Jboss.
Note: You can learn more about servlets and http, for better understanding this course @ http://javajee.com/java-ee-
web-components-part1-http-and-servlets.
6. SIMPLE SERVLET EXERCISE
• Note: May skip this exercise if you are really comfortable with Servlets and one of
tcpmon or wireshark, else follow below steps:
• Download tomcat (version 8 or anything that your eclipse support).
• Configure eclipse to use tomcat. Start, stop and restart to verify.
• Create a dynamic web project.
• Create a simple Servlet named HelloWorld.
• Execute the servlet by deploying into to tomcat from within eclipse.
• See the actual HTTP request and response using tcp mon or wireshark. You may refer to
config notes for these @ http://javajee.com/monitoring-and-analyzing-tools.
7. INTRO TO WEB SERVICE
• Web services are services exposed over a network and is designed to be
used automatically by other applications without human interaction.
• Web services communicate using standard, vendor-independent protocols such as
HTTP, XML, Javascript etc.
• Web Services vs. Web Applications
• web applications are applications with web pages primarily for use by humans
• web service is a server-based application component meant primarily for interaction with
other programs.
• Two types of Web Services: SOAP and REST.
8. OVERVIEW OF SOAP WEB SERVICES
• SOAP stands for Simple Object Access Protocol. AKA SOA Protocol.
• Contains primarily three components
• SOAP Protocol: SOAP based web services uses a special form of XML that follows a
protocol called SOAP to exchange messages.
• WSDL: Web Services Description Language is an XML-based language that is used for
describing the functionality offered by a Web service.
• UDDI: Universal Description, Discovery and Integration (UDDI) is a directory service,
and is optional.
• Message Exchange Pattern (MEP): Request Response (Input-Output), Input only,
Solicit Response (Output input), Notification or publish-subscribe (Output only).
Note: You can learn more about SOAP Web Services and Web Services in general @ http://javajee.com/web-services.
9. OVERVIEW OF REST AND DIFFERENCES
FROM SOAP
• Follow a resource oriented way:
• Every resource will be represented by a single URI and uses the standard set of http
operations like POST, GET, PUT, and DELETE, to do various operations on that
resource.
• Current state of representation is transferred using formats such as XML and JSON.
• SOAP is based on rules whereas REST is based on guidelines.
• There is no formal definitions for REST like the WSDL.
• There is WADL, but not so popular or widely accepted.
• REST support only request-response message exchange pattern.
10. JAVA SUPPORT FOR WEB SERVICES –
JAX-WS AND JAX-RS.
• Java API for XML Web services (JAX-WS) can be used for SOAP-based as well as
REST-style, but more suited for SOAP.
• JAX–WS require at least core java 5 because of the support of annotation and is part
of JDK from Java 6.
• Java API for XML – Restful web services (JAX–RS) is the standard specification for
REST web services.
• Jersy is the reference implementation for JAX-RS. Other popular implementations
include RESTEasy, Restlet and Spring REST.
Note: You can learn more about SOAP Web Services and Web Services in general @ http://javajee.com/web-services.
11. SIMPLE SOAP DEMO
• You may skip this if you don’t want to learn anything about SOAP, but if you do,
these exercises it will help you compare SOAP with REST better:
• Please do at least one of these two exercises:
• Create a simple SOAP service and deploy it in Apache Tomcat
• Create a simple SOAP service and deploy it in Glassfish Server
• Note: Notes and step by step lab for above can be found @ http://javajee.com/web-services.
