Re: [aspectj-users] LTW returning complex types 
Hi Guadalupe,
sorry, I missed your previous reply.
The aspect seems right, as long as the method InfoBook.giveMeInformationOF(String) is declared as : 

ItemBook_0Mini InfoBook.giveMeInformationOF(String s) { .. }

What i see from the exception is :
- I don't manage to understand if the exception is complete, often the InvocationTargetException is itself wrapping another inner exception, which is the real cause of failure. - The method is called on a SoapStub, so I suppose InfoBook is an interface. Could it be that the Soap stub requires it to return a stub subinterface? Therefore the book you are returning from the aspect is not the correct type to return when the call is performed on the stub? This would explain also why with strings it works correctly : strings are not stubbed.

        Hi Guadalupe,
        can you post the entire exception stack trace? It could be
        that the return type of your around advice is not compatible
        with the return type of the adviced methods.

            Hi all,
            I have tested LTW with a Web service and worked perfectly
            well when the operation intercepted in the joinpoint
            returned a basic type (such as a String).
             However when the operation returns a complex type defined
            by the user and I include an around advice in the aspect,
            I get an error.
            The error is
            "java.lang.reflect.InvocationTargetException". (When doing
            it with compile time weaving it works)
             I have tried to include the classes in the classpath when
            creating the jar and I have also created the jar also
            compiling the classes. In any case I get the same error. I
            guess it shouldnt be dificult to do this and I am probably
            missing a silly step.
             Thanks a lot for your help,
             Guadalupe
