My client code is following:
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new java.net.URL("http://localhost:9700/orabpel/default/Array"));
SOAPEnvelope env = new SOAPEnvelope();
Name bodyName = env.createName("ArrayRequest", "tns", "http://localhost/");
SOAPBodyElement request = body.addBodyElement(bodyName);
Name childName = env.createName("input","tns","http://localhost/");
SOAPElement input = request.addChildElement(childName);
input.addTextNode("ORCL");
call.invoke(env);
MessageContext mc = call.getMessageContext();
System.out.println("\n============= Response ==============");
XMLUtils.PrettyElementToStream(mc.getResponseMessage().getSOAPEnvelope().getAsDOM(), System.out);
I'am having the same error with client generated by wsdl2java.

Hi -
A few things that you may want to try to troubleshoot this issue:
1) Run our sample of calling a BPEL process from Axis, located in:
C:\orabpel\samples\interop\axis\AXISCallingSyncBPEL
2) Run your client through a TCP tunnel to see the specific SOAP request message that is being sent to the BPEL process and the SOAP response that is being generated. This should help you determine which side of the communication is causing the problem, as well as to rule out proxy server or other issues that are very common problems for this situation.
