Values can then be retrieved from the list or map using indexes or keys, respectively. An example flow demonstrates reassigning list values and logging the original and new values.
Mule Clustering
Mule clustering allows multiple Mule instances to act as a single unit. A cluster shares data through distributed memory across nodes, which can reside on the same or different machines. The document demonstrates setting up a two-node Mule cluster on the same machine by running two standalone Mule servers and registering them with a cluster manager. Key steps include starting the servers, viewing them in the server tab, creating a new cluster called Anirban_Cluster, adding both nodes to the cluster, and verifying the cluster is formed with both nodes listed.
Mule xml transformation
This document discusses how to transform an XML payload into a different XML format using XSLT in Mule. It provides an example of an input XML payload and desired output with an additional element. It then shows a Mule flow using an XSLT transformer to modify the input XML by adding the new element, with the value passed from a variable. Testing confirms the transformed XML payload is output as expected.
Parameters as a part of body
The document discusses how to map inbound message properties in Mule to the message payload using the http:body-to-parameter-map-transformer. It explains that Mule messages have properties, payload, and attachments. Properties contain things like query parameters. The transformer allows moving properties, like query parameters, into the payload. An example shows query parameters in the properties, then using the transformer to put them in the payload instead. Checking the logs confirms the parameters are now in the payload after transforming.
Mule requesterdemo
The Mule Requester component allows messages to be retrieved from inbound endpoints like JMS queues or HTTP requests within a Mule flow. It is triggered by an HTTP request hitting a URL on the server. The Mule Requester then fetches a message from a JMS queue named "input" and the message payload is logged. The Mule Requester provides the ability to interact with inbound endpoints on-demand within the flow.

Mule supports XSLT transformations using the XSLT transformer component. The example shows a flow that uses an HTTP inbound endpoint, sets an XML payload, applies an XSLT transformation defined in a file, and outputs the transformed XML. The XSLT file uses templates and XPath to map elements from the source XML to the new structure in the output XML.
Converting with custom transformer
This document discusses how to use a custom transformer in Mule to directly transform an XML payload to JSON. It provides an example of a Mule flow that uses a custom Java transformer class to take an XML file, convert it to a JSON string, and write the output to a new file. The custom transformer uses the Jackson XML and JSON libraries to perform the actual conversion between the two formats. Testing the flow results in the XML payload being successfully transformed to JSON and written out as expected.

XSLT is used to transform XML payloads between different forms. In Mule, the XSLT transformer component allows transforming XML payloads using XSLT stylesheets. For example, a flow uses an HTTP inbound endpoint, sets an XML payload, and applies an XSLT stylesheet using the XSLT transformer to output a new transformed XML payload. The XSLT stylesheet matches elements in the input XML and outputs a new structure defined in the stylesheet.
Splitting with mule part2
Mule ESB can split a large message into smaller parts using a Splitter flow control component. This allows large messages containing repeating elements, like a list, to be broken into individual fragments that can then be processed separately. The document demonstrates using a Splitter to break up a JSON payload containing an array of "events" into separate logs of each event's ID and timestamp, handling the large list efficiently. Splitters are useful for processing large repeating data in XML or JSON payloads.

Values can then be retrieved from the list or map using indexes or keys, and the list values can be reassigned. For example, a list variable can be set as #[{1000,100,14,1}] and values retrieved using flowVars['test'][0]. Similarly, a map can be set as #[['k2':'new', 'k3':'v3']] and values retrieved using flowVars['customMap']['k2'].
Using map and list starter
This document discusses how to define lists and maps using Mule variables. It shows that lists and maps can be defined by assigning a Mule variable to a value expressed as a JSON array or object. Values can then be retrieved from the list or map using array indexing or object properties. The document provides an example Mule flow that demonstrates defining, accessing, and modifying list variable values.

Xml transform
This document discusses using XSLT to transform XML payloads in Mule applications. It provides an example of transforming an input XML payload containing name and id elements to an output XML payload that adds a designation element. The Mule flow uses an XSLT transformer applied to the input XML, along with an XSL stylesheet, to produce the modified output XML payload. Testing the flow by deploying it and sending a request demonstrates how XSLT can easily transform XML payloads in Mule.
Multi database access
The document discusses using the Scatter-Gather routing message processor in Mule to retrieve data from multiple databases concurrently. It demonstrates a flow that retrieves data from both a SQL Server and PostgreSQL database in parallel using Scatter-Gather and aggregates the results into a single payload. The flow is tested by hitting a URL that returns the combined data from both databases.
Xml to xml transformation in mule
This document discusses how to transform an XML payload into another XML format in Mule. It presents an example of taking an input XML with elements for name and id, and transforming it to an output XML with an additional element for designation. This is done using an XSLT transformation in Mule, with the XSLT file modifying the input XML and adding the new designation element. Testing confirms that the Mule flow with XSLT transformer successfully transforms the input XML into the desired output format.
Xml to xml transformation in mule
This document discusses how to transform an XML payload into another XML format using XSLT in Mule. It provides an example of taking an input XML payload with two elements, name and id, and transforming it to an output XML payload with an additional element, designation. The transformation is done with an XSLT file that is referenced in the Mule flow. The flow accepts the XML as input, sets a designation variable, runs the payload through the XSLT transformer to modify it according to the XSLT, and outputs the transformed XML payload.
SQL
This document provides information on various SQL concepts including variables, tables, loops, control flow, cursors, triggers, views, and stored procedures/functions. It defines SQL variables and temporary tables, describes different types of loops in SQL. It also explains control flow functions like IF and CASE, how to use cursors to access result sets row by row, when triggers are used and how to create them, how views allow querying data from other tables or views, and benefits of stored routines.

Mule architecture
Mule is a lightweight integration platform that enables connecting systems, services, APIs, and devices. It manages message routing, data mapping, orchestration, reliability, security, and scalability between nodes. Mule architecture is based on Enterprise Service Bus concepts and allows applications to communicate by carrying data between them. A Mule flow processes messages through a sequence of message sources, processors, and endpoints to integrate applications on-premise or in the cloud.
Mule anypoint exchange
This document discusses Anypoint Exchange in Mule, listing it as a product and pattern. It is classified by difficulty (easy, average, difficult) and object types like account, contact, and opportunity. Videos are also listed. Patterns discussed include aggregation, bi-directional, and broadcast integration patterns.
Mule soap
The document discusses validating SOAP requests against an XSD schema file in Mule. It explains how to use a schema validation filter to validate the SOAP request and throw a custom error message if invalid. The code sample shows placing the filter before the SOAP service, and adding a subflow to handle invalid requests. The schema validation filter refers to the XSD file and validates the request against it.
Mule security jaas
The document discusses how to configure the JaasSimpleAuthenticationProvider security provider in Mule to use the Jaas Authentication Service. It describes two configuration methods - passing a Jaas configuration file that defines login modules and credentials, or configuring attributes directly on the provider. The Jaas configuration file example shows a file defining a login module, required flag, and authorized users mapped to passwords.
Mule integration with linkedin
To integrate Mule with LinkedIn, developers must create an app in LinkedIn Developer, which generates client ID and secret keys to authenticate with LinkedIn APIs. The Mule flow first authorizes with LinkedIn to get an access token, then uses it to call the GetProfileByURL operation and return a user's details by LinkedIn URL.
Mule esb stripe
MuleSoft's Stripe connector allows developers to integrate their MuleSoft applications with the Stripe API to perform payment-related functions like accepting payments, creating invoices and customers. The document provides steps for setting up a Stripe developer account, configuring the Stripe API key, installing MuleSoft's Stripe connector, and creating a sample Mule application that uses the Stripe connector to create a customer and coupon.
Mule esb api layer
The document discusses API layers in Mule and their uses. An API layer offers a decoupled interface for interacting with applications through a common language-agnostic way. Common uses of API layers include connecting to legacy systems that lack REST APIs and publishing APIs for partners to communicate with systems. The Anypoint Platform helps build, design, and manage APIs to expose enterprise data securely to various devices and apps. It includes an API gateway to connect to backends behind firewalls, an API manager to manage users and traffic, an API contract manager to issue keys and monitor compliance, and an API policy manager to apply security policies without downtime.
Mmc
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against developing mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.
Mmc rest api user groups
This document outlines the REST API operations for managing user groups in Mule Management Console (MMC), including creating, getting, updating, and deleting user groups. It also covers getting all user groups and permissions. The operations use HTTP methods like POST, GET, PUT, and DELETE and require basic authentication with a username and password to invoke the API endpoints on the MMC server.
How to use message properties component
This document discusses using message properties in Mule applications. It provides an example Mule configuration file that demonstrates setting message properties in different scopes and logging their values. The example shows setting a property in the session scope and outbound scope in one flow, and accessing the same properties from the inbound scope in a second flow to illustrate how message properties function.
How to use expression filter
The document discusses using expression filters in Mule applications. It provides an example Mule configuration file that uses an expression filter to check the value of a session variable and route the message to a second flow if the value is not equal to "mule". The output shows the message being logged in both flows, demonstrating that the expression filter passed the message to the second flow since the session variable value was "mule studio" rather than just "mule".
Data weave
The document discusses how to use the DataWeave transformer in Anypoint Studio to transform messages. The DataWeave transformer allows writing transformations using the DataWeave language. It takes the incoming message elements as inputs and performs actions to produce an output message. The editor provides autocomplete, output previews, and generates .dwl files to store the transformation code. Multiple outputs can be defined by adding tabs in the transform section.
Creating dynamic json
This document discusses how to dynamically generate JSON payloads in Mule ESB flows. It shows how to use an expression transformer to generate a sample JSON payload with values from flow variables. The generated JSON is then posted to an external service, which returns a response. Testing the flow by hitting a URL generates the JSON request and logs the request and response, demonstrating how to dynamically create and use JSON in Mule.
Converting with custom transforme
This document discusses how to use a custom transformer in Mule to directly transform an XML payload to JSON. It provides an example of a Mule flow that uses a custom Java transformer class to take the XML from a file, convert it to a JSON string using Jackson libraries, and write the JSON output to a new file. The custom transformer allows transforming the payload in a single step without using multiple standard transformers. The example demonstrates how to implement the custom transformer class and integrate it into a Mule flow to achieve direct XML to JSON transformation.
Caching and invalidating with managed store
This document discusses how to use caching with the NonPersistentManagedObjectStore in Mule and invalidate the cache. It shows how to configure caching in a flow using the NonPersistentManagedObjectStore, test the cached response by deleting data from the database, and create a flow to invalidate the cache. When the cache is invalidated and the service is called again, it will retrieve new data from the database rather than serving the cached response.
Cache for community edition
This document discusses implementing a cache in Mule Community Edition using a custom interceptor since Community Edition does not include the cache scope feature of Enterprise Edition. It provides an example of a custom interceptor class that caches payload data and includes a code sample. The document then demonstrates configuring and testing the custom cache interceptor on a web service that retrieves database records, showing that it continues returning the cached response even after the underlying database record is deleted.
Automatic documantation with mule
Anypoint Studio has a feature to automatically generate documentation for Mule projects. The documentation plugin allows users to generate an HTML report of all flows, elements, and code including attributes and descriptions provided in doc:name tags. Users select a folder location and the documentation is generated, containing both graphical and XML representations of all flows and components in the project. This simplifies the process of documenting Mule applications within the IDE.
A simple webservice with vm
The document discusses using VM components in Mule to decompose a complex flow into smaller pieces to improve performance and control. It shows how to expose a CXF web service by breaking the flow into two parts connected by VM queues. This allows controlling each event queue separately and preventing overcommitting of resources. It demonstrates storing message properties before sending to the VM queue to retain them for the next flow, since properties may be lost passing through VM.
mule salesforce
This document provides steps to perform CRUD (create, read, update, delete) operations on Salesforce using Mule ESB. It involves setting up a Salesforce developer account, creating a security token, configuring a Salesforce connector in Mule, and creating Java classes to handle the different operations. The flows create a contact, read it, update fields, read it again, and delete it. Extracts from the logs show the requests and responses for each step.
mulesoft filters
The document discusses MuleSoft filters which can be used to determine whether messages pass through application flows or are dropped. It provides examples of built-in filters like AND, OR, and NOT filters as well as expression filters. Custom global filters can also be created. The agenda indicates the topic of filters will be continued in the next session, and references MuleSoft's website for additional information.

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).

Mapping and listing with mule
- 1. Mapping and Listing with Mule
- 2. Mule ESB has the ability to store data into variables. Fortunately Mule offers 2 types of variables 1) Flow variables that has scope limited to a flow and subflow and 2) Session variables that has scope and can be accessed from entire application. Now, one interesting facts I come across several Mule users is how to define a List or a Map with a variable in Mule in the same way as Java. Let me tell you, this is absolutely possible with Mule. We can define List or a Map in Mule with Mule variables.
- 4. We can define a List with a Mule variable in following ways :- <set-variable variableName="test" value="#[{1000,100,14,1}]" doc:name="Variable"/> Or <set-variable variableName="test" value="#[[1000,100,14,1]]" doc:name="Variable"/> Here you can see we define a variable named as test which is defined as a List
- 5. Now, we can get the values from the List as follow :- <logger level="INFO" message="#[flowVars['test'][0]]" doc:name="Logger"/> <logger level="INFO" message="#[flowVars['test'][1]]" doc:name="Logger"/> <logger level="INFO" message="#[flowVars['test'][2]]" doc:name="Logger"/> <logger level="INFO" message="#[flowVars['test'][3]]" doc:name="Logger"/> As you can see we are retrieving the values from the List with the index
- 6. Now, we can define a Map in the same way as follow :- <set-variable variableName="customMap" value="#[{'k2':'new', 'k3':'v3'}]" /> Or <set-variable variableName="customMap" value="#[['k2':'new', 'k3':'v3‘]]" /> Here you can see we define a variable named as customMap which is defined as a Map
- 7. Now, we can get the values from the Map as follow :- <logger message="#[flowVars['customMap']['k2']] " level="INFO" doc:name="Logger"/> <logger message="#[flowVars['customMap']['k3']] " level="INFO" doc:name="Logger"/> As you can see we are retrieving the values from the Map with the key
- 8. Now, let us consider a simple flow to demonstrate the List and the Map as follow :-
- 9. The Mule config will be :- You can see here we are using Expression component to reassign our List value of index 1 and index 2 … Then we are using logger to print the new value of List again in the console
- 10. So, if we test the example we will get all the value of List and Map variables as follow as well as with new reassigned value :-
- 11. So, here you can see how to use a List and Map with Mule variable… Hope I was clear enough to give an Idea of it’s implementation ….
- 12. In my next slide I will bring some other techniques in Mule implementation . Hope you have enjoyed this simpler version. Keep sharing your knowledge and let our Mule community grow
