Hi all,
it has been trouble me for days that i can not invoke an Ode deployed BPEL
service. I am using the latest Ode (version 504778). I have a very simple
HelloWorld BPEL and there is no problem of deploying the process.
When i invoke it, i always get follow exceptions no matter what i changed to
both server and client sides:
E:\Workplace_Webservices\Ode_helloworld_client\client\build\classes>java
