Java.lang.NullPointerException at org.collaxa.thirdparty.apache.wsif.base.

Question

Hi,
I am trying to invoke a Websservice, which has JCA bindings, using the WSIF framework. Getting a null pointer exception:
Have posted the code and error below.
CODE SNIPPET:
====================================================================
try{
/* if (Thread.currentThread().getContextClassLoader() == null) {
ClassLoader cl = getClass().getClassLoader();
Thread.currentThread().setContextClassLoader(cl);
oracle.tip.adapter.fw.wsif.jca.WSIFDynamicProvider_JCA provider = new oracle.tip.adapter.fw.wsif.jca.WSIFDynamicProvider_JCA();
org.collaxa.thirdparty.apache.wsif.util.WSIFPluggableProviders.overrideDefaultProvider("http://xmlns.oracle.com/pcbpel/wsdl/jca/", provider);
Definition wsdlDefinition = WSIFUtils.readWSDL(null, "C:\\SOAPJCA\\BRMCustServices.wsdl");
Service wsdlService = wsdlDefinition.getService(new QName("http://xmlns.oracle.com/BRM/schemas/BusinessOpcodes") );
org.collaxa.thirdparty.apache.wsif.WSIFServiceFactory wsifFactory = org.collaxa.thirdparty.apache.wsif.WSIFServiceFactory.newInstance();
WSIFService wsifService = wsifFactory.getService(wsdlDefinition, wsdlService);
String portChosen = null;
Iterator it = wsifService.getAvailablePortNames();
while (it.hasNext()) {
String nextPort = (String) it.next();
if (portChosen == null)
portChosen = nextPort;
System.out.println(" - " + nextPort);
WSIFPort port_wsif = wsifService.getPort();
System.out.println("After that !!");
//WSIFPort javaPort = wsifService.getPort("");
}catch(WSIFException wsifEx){
System.out.println("Within WSIF exceptions");
wsifEx.printStackTrace();
====================================================================
ERROR:

=====================================================================
The jars used here are orabpel related jars, which has its own JCA provider and implementation classes. There are similar errors reported in Axis WSIF forums for:
Null pointer Exception at apache.wsif.base.WSIFServiceImpl.createDynamicWSIFPort
But no concrete answers to it.
Has anyone tried using WSIF in Oc4j,
Any help is appreciated.
Thanks,

It says "*unique* constraint (XXEA_GLOBAL.XXEA_GL_JOURNAL_IN_STG_U1) violated". Pls check if your data (for insertion) is violating this constraint.
