Hi fellow WSIF users.
I am trying to create a simple client to call BPEL processes through the
WSIF framework. I use the Axis SOAP provider, but I seem to be running into
some namespace issues. The BPEL process has a "process" method that takes in
a person element consisting of name and address fields. The type is defined
in an XSD imported into the wsdl. Here's the BPEL process' WSDL definition:
------------------------------------------------------------
<definitions
name="ConvertPerson"
targetNamespace="http://ciber.no/ConvertPerson";
xmlns="http://schemas.xmlsoap.org/wsdl/";

Here's the Person.xsd
---------------------------------------------------------------
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";

targetNamespace="http://types.ciber.no";

Here is my java code:
-----------------------------------------------------------------------------------
package no.ciber.wsiftest;
import javax.xml.namespace.QName;
import junit.framework.TestCase;
import org.apache.wsif.WSIFMessage;
import org.apache.wsif.WSIFOperation;
import org.apache.wsif.WSIFPort;
import org.apache.wsif.WSIFService;
import org.apache.wsif.WSIFServiceFactory;
public class Client extends TestCase {
public void testProcess() {
String wsdlLocation =
"http://NOLMarApa:9700/orabpel/default/ConvertPerson/1.0/ConvertPerson?wsdl";;
WSIFServiceFactory factory =
WSIFServiceFactory.newInstance();
try {
WSIFService service =
factory.getService(wsdlLocation,
null,
"ConvertPerson",
null,
"ConvertPerson");
service.mapType(new
QName("http://types.ciber.no","person";),
Person.class);
service.mapType(new
QName("http://types.ciber.no","ConvertedPerson";),
ConvertedPerson.class);
WSIFPort port =
service.getPort("ConvertPersonPort");
WSIFOperation operation =
port.createOperation("process",
"PersonConvertRequestMessage", "PersonConvertResponseMessage");
WSIFMessage inputMessage =
operation.createInputMessage();
WSIFMessage outputMessage =
operation.createOutputMessage();
WSIFMessage faultMessage =
operation.createFaultMessage();
Person request = new Person();
request.setName("John Doe");
request.setAddress("Mystreet 11");
inputMessage.setObjectPart("payload", request);
boolean success =
operation.executeRequestResponseOperation(inputMessage, outputMessage,
faultMessage);
if(success== true) {
ConvertedPerson response =
(ConvertedPerson)
outputMessage.getObjectPart("payload");
System.out.println("Recieved: " +
response.getResult());
} else {
System.err.println("Something else
happened!");
}
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String []args) {
Client client = new Client();
client.testProcess();
}
}
-------------------------------------------------------------------------------------------------------
The Person.java object representing the request element, is a simple
JavaBean with name and address variables.
What happens?
When calling the BPEL process using this code, WSIF somehow mixes up the
namespace of the Person object. A correct request message payload should be:
<person xmlns="http://types.ciber.no";><name>John Doe</name><address>Mystreet
11</address></person></part>
However, WSIF produces the following request object:
<person><address>Mystreet 11</address><name>John Doe</name></person>
As shown, WSIF omits the "http://types.ciber.no"; namespace in the <person>
elements. This results in an error since the BPEL process can't resolve the
xpath expression /ns1:person/ns1:name or ns1:address
This call was made using the 2.0.1_IB3 . The 2.0 version also fails.
Does anyone have a clue what's happening here?
