How do I edit the file created by code generator?

Question

hi all,
I want to modify a java file that is generated when you create the webdynpro, but I can not change.
// This file has been generated partially by the Web Dynpro Code Generator.
// MODIFY CODE ONLY IN SECTIONS ENCLOSED BY @@begin AND @@end.
// ALL OTHER CHANGES WILL BE LOST IF THE FILE IS REGENERATED.
how can I disable the file to modify
thanks!

Hi Pablo.
There's no way to modify it, NW2004s and its IDE has a code compilation based in some internal scripts based on eclipse plugin architecture.
In your code you must consider this.
1 - Try to find in your declared methods, importing directives, packages declarations  some like this:
// This file has been generated partially by the Web Dynpro Code Generator.
// MODIFY CODE ONLY IN SECTIONS ENCLOSED BY @@begin AND @@end.
// ALL OTHER CHANGES WILL BE LOST IF THE FILE IS REGENERATED.
package com.sap.teste;
// IMPORTANT NOTE:
// ALL IMPORT STATEMENTS MUST BE PLACED IN THE FOLLOWING SECTION ENCLOSED
// BY @@begin imports AND @@end. FURTHERMORE, THIS SECTION MUST ALWAYS CONTAIN
// AT LEAST ONE IMPORT STATEMENT (E.G. THAT FOR IPrivateTesteApp).
// OTHERWISE, USING THE ECLIPSE FUNCTION "Organize Imports" FOLLOWED BY
// A WEB DYNPRO CODE GENERATION (E.G. PROJECT BUILD) WILL RESULT IN THE LOSS
// OF IMPORT STATEMENTS.
//@@begin imports
import com.sap.teste.wdp.IPrivateTesteApp;
import com.sap.myimport.MyClass;
//@@end
//@@begin
//@@end
it means that between begin and end...you can add what you want..and the code will not be removed after class compilation....
  //@@begin javadoc:wdDoExit()
  /** Hook method called to clean up controller. */
  //@@end
  public void wdDoExit()
    //@@begin wdDoExit()
    //@@end
int this case too....if you implement something between //@@begin and //@@end in the method scope...all part of your code will be surely safe.
