Hi Jiang,
It looks like the exception is happening on the client side during the XML
serialization of your request message and before it's ever sent to Ode.
Could you share with us your client code? Feel free to open a new issue at
http://issues.apache.org/jira/browse/ODE and attach a ZIP of your project:
client code, BPEL files, etc.
thanks,
alex

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:
