> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Environment: windows xp
> Reporter: Shree Rangan
>
> I have a POJO exposed as a Webservice using Axis2. I have tested this
> service using RPCServiceClient and it works fine. This service needs to talk
> to other services which are also POJO's exposed as Webservices using Axis2.
> The other services also work fine when invoked by RPCServiceClient mechanism.
> But if I invoke those services from my Axis2 service using the same mechanism
> of RPCServiceClient mechanism, it gives me the following exception.
