It little more complicated than that. You could think like, user gives me
class file(The class can have any kind of methods.). I am just using a POJO
deployment feature in the Axis 2.
As of now I dont check the class files for these kinds of method. If I were
to do what you suggested, it would be more complex.
1) I need to inspect the class file passed to me to find such kind of
methods.
2) Somehow I need to generate a new class file by modifying the method
signature and instructions.
3) Use this new file for axis service. And when the value is returned, I
again need to make sure whether to return it or not.
Moreover, I think this might be a bug in Axis 2.
Thanks,
Paul
