The ClassNotFoundException indicates that you only have WindowBuilder partially installed. A full install will take care of this.

Comment 3 Gilles Remy

Hello,


I am sorry, but i have looked at the source code and there is really a reference to a class that does not exists in Eclipse 3.6.2 (Windows and Linux):
org.eclipse.jdt.core.dom.AnonymousTypeDeclaration2

This reference is not in the class:
org.eclipse.wb.internal.core.parser.JavaInfoParser
but, if i remember well, in the class:
org.eclipse.wb.internal.core.utils.ast.AstEditor

I have compiled and added the missing class to my Eclipse and now everything works.


Best regards


P.S.: The problem does not occurs every time, sometimes it works sometimes not.

Comment 4 Eric Clayberg

The class org.eclipse.jdt.core.dom.AnonymousTypeDeclaration2 is part of WindowBuilder itself. As I stated earlier, this ClassNotFoundException indicates that you only have WindowBuilder partially installed. A full install will take care of this. There is no need to compile or add anything to Eclipse as this class is part of the normal WindowBuilder distribution.

Thank you very much. It was effectively an installation problem.
