Hello,
I've created a simple business process the Helloworld. In this business
process I'm making a call to an external web service which I've added
using using the + plus sign for adding a partner Link.
I'm using ODE 1.1.1,Apache Tomcat 5.5, and Axis 1.4
My BPEL process looks like the following:
<!-- HelloWorld BPEL Process [Generated by the Eclipse BPEL Designer] -->
<bpel:process name="HelloWorld"

------------------------------
Afterwards I've created a simple Java application and added a new web
service client i.e the wsdl file for the BPEL process, and I try to call
my business process using the following code:
HelloWorldLocator service;
HelloWorldSOAP12BindingStub soap11Service;
service = new HelloWorldLocator();
service.setEndpointAddress(new QName("HelloWorldSOAP12port_http"),
"http://localhost:8080/ode/processes/HelloWorld");
soap11Service = new HelloWorldSOAP12BindingStub(new
URL("http://localhost:8080/ode/processes/HelloWorld"),service);
HelloWorldRequest inpart = new HelloWorldRequest();
inpart.setInput("Hello World");
HelloWorldResponse response = soap11Service.process(inpart);
And I'm getting the following error in Eclipse console:
