Mendix and Java

Hi all, I am new in Mendix and i have this issue i dont know how to solve it. I want to use Java action. I have created one which takes one Mendix object(entity) and returns other object(another entity). I have deploy it my mendix project to eclipse and import it. Now i have in eclipse executeAction() method generated. I am a java programmer, but i dont know the commands to retrieve attributes, store attributes creates new objects(means entities). Please can you provide me some code example, which take String_1 attribute from first entity makes some operations, for example String_2 = String_1 + "test message"; and store it to second entity as String_2 attribute?? Regards, Lukas

Have you looked at this Java API tutorial?

For other stuff you could look at the Core class, this provides most of the API methods.
