This job does three things.
1. Creates a new class, compiles and saves it.
2. Finds the class and adds a new static method to it.
3. Calls the new method using DictClass.
If you want to you can just add to the newClassBuld.classNode() instead of finding it again as I do in this example. I did it this way to show both how to create a new class and how to add methods to an existing class.
This job was created in Dynamics AX 4.0 and has not been tested in any other version.

Awesome, just what I was looking for!
Not bad!
but how about a derived class?
Just add this on line 20:
newClassBuild.addMethod(‘classdeclaration’, ‘public class ‘ + className + ‘ extends FormLetter \n{\n}\n’);
This makes the class extend from FormLetter, maybe a bad example, but I think you get the point. Just change the “FormLetter” part to the class you want to extend.
What this means is that if you don´t add a classdeclaration, the ClassBuild class will create a default classdeclaration for you. If you don´t want this, add it manually like any other method.
