DataWeave 2.0

DataWeave – Tip #3

I have already presented how to call Java code using messages processors with the newest Java Module for Mule 4.x.

However for scenarios when we would like to use custom code in DataWeave, for transformations, another approach is needed. Approach presented in this article will be more concise comparing to using message processors. It was highly extended comparing to possibilities of Mule 3.x version. Mule 3 allowed to invoke static methods. In contract Mule 4 not only permits to call static methods but also instantiate classes and access its instance attributes.
