The Groovy Component is also handy for when you’re modernizing legacy systems, as you can simply throw the old lines of code into a component instead of having to reengineer the code’s behavior through a series of different Mule components (this is not ideal from a debugging and maintenance perspective, though).
2. Add and configure the file component as inbound and outbound. Add a Groovy component between the two file components: 3. Add a script in the Groovy configuration: 4. Save and run the ...
Groovy has an issue of loosing payload if you don't return at the end, so, in Groovy you need to return the payload at end, and that's the reason you are receiving null payload. Alternately you can use expression-component as follow:-
Ergo, where the custom code converts data from one representation format to another, implement it as a transformer; where it creates new data, implement it as a component.. But, of course, there’s just a little more to it. Let’s take a closer look at the flow: as you can see, all transformers are defined globally.
In this definition, we implement the Groovy logic to derive the corresponding airline code, which is known as the IATA Carrier code. After invoking Groovy component, the payload is set as the return value from the Groovy code, which holds the IATA Carrier code. Here’s the flow definition from the Mule configuration file:
1. Using your code, add: import org.mule.api.transport.*; 2. Use: def x = sessionVars[‘parameter1’].toInteger(); (without the ‘import’) What I am really hoping for is to be able to defne Groovy with code assist, as for Java, and to then test it using JUnit. The only reason for using Groovy is for a complex operation.

The flexible syntax, combined with runtime and compile-time metaprogramming capabilities make Groovy an interesting choice because it allows the programmer to focus on the DSL rather than on tooling or implementation. Since Groovy DSLs are Groovy code, it’s easy to have IDE support without having to write a dedicated plugin for example.
When using the Groovy scripting component in an application, if the script returns a null output, Groovy returns a GString object with a null value, which Mule is trying to serialize.

The choice flow control dynamically routes messages based on message payload or properties. It adds conditional programming to a flow, similar to an if/then/else code block. A choice flow control uses expressions to evaluate the content of a message, then it routes the message to one of the routing options within its scope.
