Hi Raymond,
thanks for your answer. I debug my application and sca
source.
Next I will try to explain the invocation chain:
When JDKInvocationHandler calls method invoke(InvocationChain chain,
Object[] args, RuntimeWire wire, EndpointReference source)
line 288: Message resp = headInvoker.invoke(msg); // invocation occurs
without errors
line 289: Object body = resp.getBody(); // Returns an
org.apache.tuscany.sdo.impl.AnyTypeDataObjectImpl object
It seems that body was not instantiated with the correct class.
Cite:
" I suggest that you open a JIRA and attach the test case there so
that we can debug."
I'll try this, i never did that before. What I need to post there?
For the moment I'll publish my problem here.
