| Re: [aspectj-users] LTW returning complex types |
Hi Simone and Andy,InfoBook is the Interface implemented by the service, which offers one operation (giveMeInformationOF(String)) which returns ItemBook_0Mini (ItemBook_0Mini is a bean, which simply contains several Strings).The service works with this type without the aspect, so there shouldn´t be any problem with its serialization; it is when the around advice is included when it does not work any more.What could it be?Thanks a lot,Guadalupe2009/5/13 Simone Gianni <simoneg@xxxxxxxxxx>
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
