Mule ESB is a lightweight and highly scalable Java-based enterprise service bus (ESB) and integration platform provided by MuleSoft. The following example below explains the different views you will use to build a Mule project: Your Mule Palette should already include the HTTP module. However, DataWeave is also available in other contexts, like as a command-line tool. Configuration In this Mule tutorial we will learn how to Create Mule 4 project with RAML and a detailed walk-through on how the Mule flow works in case of a success or error scenario: RAML stands for RESTful API Modeling Language and is similar to WSDL. Leverage our command-line interface to: Query, filter, and map structured data from different sources like JSON, XML, CSV, and YAML. However, because it is simpler, there is less to learn and less for you to manage. To complete the above scenario, we will be using Flow Reference. In mule 3 we have roll back exception strategy which enables the ability to retry the execution in case of error and define a separate flow to be executed once the retry count has exceeded. Logs: In the logs we can see that the messages are processed in parallel. Create and push dynamic configuration files to other systems. We also simplified enrichments. This can be a problem if we want to deploy our application on Production servers; data can get modified even before Mule APIs is deployed successfully. Part 4: LambdasWhat is DataWeave? In the Input panel payload tab, replace all the question marks with data. For example in the below Flow, when flow execution starts, point 1, 2, 3 will execute first, on error at point 3 the error is catch by on-error propagate and error processing begins with point 6, 7; once the error handling flow is completed the flow processing ends and an error is re-thrown to its parent flow.
