Sounds plausible, but how would a MethodFilter help? It can retrieve
the TransformMethodSignature, but how to use that to create an advise?
Hmm... just took a look at the code again and I think I see the problem.
///// This creates the method body if your class doesn't already implement it:
transformation.addImplementedInterface(RequestParameterExtractor.class);
TransformMethodSignature extractMethod = new
TransformMethodSignature(Modifier.PUBLIC,
"Map<String, String>", "extractRequestParameters", null, null);
///// This is probably commented out because it always returns.
// if (transformation.isDeclaredMethod(extractMethod)) {
// return;
// }
///// This is apparently trying to re-create the method.
transformation.getOrCreateMethod(extractMethod).addAdvice(new
ComponentMethodAdvice(){
You should call transformation.findMethods(filter); instead of
getOrCreateMethod. I'm not sure why the getOrCreate is trying to
implement the method if it's already there, but I'd guess it has
something to do with your new TransformMethodSignature.

Same Error
@Josh
Yes, I also removed the Generic Map from the Interface.
Just checked in debug method: the method indeed already exists (breakpoint:
line 1443 InternalClassTransformationImpl). But how come? Its never added
through my code.
Did you take the type parameters off of the interface too (return a
raw map)? Have you looked at with a debugger? Stick a breakpoint right
before the exception and take a look at the methods in the ctclass.
I can't look at it now but I'll try to reproduce the problem tonight.

Have you tried without specify Generic types ?

Oh, this is maybe due to generics...
2010/9/13 Markus Feindler<markus.feind...@gmx.de>
public interface RequestParameterExtractor {
Map<String, String> extractRequestParameters();
}
is not equal to:
TransformMethodSignature extractMethod = new
TransformMethodSignature(Modifier.PUBLIC,
"Map<String, String>", "extractRequestParameters", null,
null);
?
Everything looks good ... The only thing i see is that the method
signature
is not exactly the same as the one declared in the interface.
