XML format for input to BPEL process from client stub

Question

Hi,
I have deployed SyncHelloWorld BPEL process as given in the tutorial in the BPEL Server. It is working fine. Now I am trying to invoke the process by creating a Java client stub . I created a stub using the Web-services wizard by specifying the WSDL of the BPEL. Now I want to know how to pass some string through XML document to the BPEL process.
I am using this code in the main method of the stub., but the value is not being passed to the BPEL nodes correctly. the output I am getting is "Hello "
and not "Hello XYZString". I think I am not able to form the XML document to pass as input correctly. Can anyone help.
Can anyone please help :
public static void main(String[] args)
try
SyncHelloWorldStub stub = new SyncHelloWorldStub();
// Add your own code here.
// Create an empty XML document
XMLDocument doc = new XMLDocument();
// Create an element
Element body = doc.createElementNS("http://xmlns.oracle.com/SyncHelloWorld", "SyncHelloWorldProcessRequest");
// Create the inner element
Element ip = doc.createElementNS("http://xmlns.oracle.com/SyncHelloWorld", "input");
// Create a text node
Text text = doc.createTextNode("input");
// Set the input parameter
text.setNodeValue("XYZString");
ip.appendChild(text);
body.appendChild(ip);
// Call the process. It returns a vector
Vector v = stub.process(body);
// Code to print the returned xml.
System.out.println("Received " + v.size() + " element");
Enumeration enum = v.elements();
// Walk through the vector and print out contents
while (enum.hasMoreElements())
Object o = enum.nextElement();
System.out.println("Returned a " + o.getClass().getName());
//If it is an element, print it out
if (o instanceof XMLElement)
XMLElement xml = (XMLElement)o;
xml.print(System.out);
else
System.out.println("Returned " + o.toString());
System.out.println("After executing : "+v.toString());
catch(Exception ex)
ex.printStackTrace();
This is the code for WSDL file for the BPEL process.

Also, while running the BPEL process from console, we can give the input as html or string. Can anyone give the me xml format of the input.
Any help would be highly appreciated.
Thanks,

Answer 1

Your last question shows that you might have solved this by now.
The xml document you are composing in java might not exactly be the xml input bpel excepts. The way to compare is first initiate a process by posting an html message, using the initiate tab for your process in the BPEL console. Check the box "Save as default input" before you send the html request.
Then again do an initiate from the BPEL console and select "XML Source" instead of "HTML Form". You will see the xml message you just have sent as html.
You might also want to test your java program with one of the many free soap clients available on the internet.
