[jboss-user] [JBoss jBPM] - Re: Problem testing Hello BPEL sample

[zauberlehrling]

I have similar problems with the following environment:

1. jBoss BPEL 1.1 Beta2
2. jBoss AS 4.0.5GA
3. jwsdp-2.0
4. jdk 1.5.0_08
5. ANT 1.6.5

I've tried to call the hello-bpel-process with the following code:
public void test()
  | {
  |   try {
  |     Properties properties = new Properties();
  |     properties.setProperty("java.naming.provider.url", "jnp://localhost:1099");  
  |     properties.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
  |     properties.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming.client");
  |     properties.setProperty("j2ee.clientName", "jbpmbpel-client");
  |     Service service = null;
  |     if (service == null) {
  |       InitialContext iniCtx = new InitialContext(properties);
  |       Object object = iniCtx.lookup("java:comp/env/service/Hello");
  |       service = (Service)object;
  |       String portTypeNS = "http://jbpm.org/examples/hello";
  |       Call call = service.createCall(new QName(portTypeNS, "GreeterPort"),"sayHello");
  |       String greeting = (String) call.invoke(new Object[] { "Olive" });			    
  |       System.out.println("Greeting: "+greeting);
  |     }
  |   } catch (Exception e) {
  |       e.printStackTrace();
  | }
  | 	
and I get the following exception:
javax.naming.NamingException: Cannot unmarshall service ref meta data, cause: java.io.InvalidClassException: javax.xml.namespace.QName; local class incompatible: stream classdesc serialVersionUID = 4418622981026545151, local class serialVersionUID = -9120448754896609940

  | 	at $Proxy0.lookup(Unknown Source)
  | 	at javax.naming.InitialContext.lookup(InitialContext.java:351)
  | 	at frank.DII.test(DII.java:51)
The exception is thrown by the command in line 51:

  | Object object = iniCtx.lookup("java:comp/env/service/Hello");
  | 
If I try to contact the webservice with the following code:

  | public void dii()
  | {
  |   try {
  |     String endpoint = "http://localhost:8080/hello/greeter?wsdl&resource=hello.wsdl";
  |     QName qName = new QName(endpoint);
  |     ServiceFactory serviceFactory = ServiceFactory.newInstance();
  |     Service service = serviceFactory.createService(qName);
  | 		
  |     Call call = service.createCall();			
  |     call.setOperationName(new QName(endpoint,"sayHello"));
  |     call.setTargetEndpointAddress(endpoint);
  | 
  |     call.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY,"http://schemas.xmlsoap.org/soap/encoding/"); 
  |     call.setProperty(Call.OPERATION_STYLE_PROPERTY, "rpc"); 		
  | 
  |     Object[] arguments = new Object[] {"wo"};
  |     Object result = call.invoke(arguments);
  |     System.out.println(""+result);		
  |   } catch (Exception e) {
  |      e.printStackTrace();
  |   }
  | }
  | 
I get the following exception in the server console:

At least this code contacted the bpel engine.
