Class Copy

[yugo_amaril <ga...@iit.cnr.it>]

Hi. I'm using BCEL to create a copy of a given class. I'd like to have a
perfect copy, in the same package, but with a different name. I'm trying
with this code, but when I execute a program using the new class I always
have an Error:

pubic ClassGen copy(ClassGen clazz) {

   JavaClass jClazz = clazz.getJavaClass().copy();
   // creates a proxy class
   jClazz.setClassName(jClazz.getClassName()+"_copy");
   ConstantPoolGen cp = new ConstantPoolGen(jClazz.getConstantPool());
   cp.setConstant(cp.lookupUtf8(jClazz.getFileName()), new
ConstantUtf8(wrapFileName(jClazz.getFileName())));
		
   jClazz.setFileName(wrapFileName(jClazz.getFileName()));
		
   ClassGen copy = new ClassGen(jClazz);
}
// and after i dump the class in the right file

where wrapFileName(String name) creates the correct file name (e.g.
"MyFile.java --> MyFile_copy.java")

The Error is:
Exception in thread "main" java.lang.NoClassDefFoundError: pkg/MyClass_copy
(wrong name: pkg/MyClass)

What's wrong?

Thanks in advance for any suggestion.
