Calling BPEL service using axis client

Question

Hi,
I have created and deployed simple BPEL process and i am trying to invoke this BPEL process using axis client.
deployed BPEL wsdl is as follows
<?xml version="1.0" encoding="UTF-8" ?>
- <definitions name="SimpleProcess" targetNamespace="http://xmlns.oracle.com/SimpleProcess" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://xmlns.oracle.com/SimpleProcess" xmlns:plnk="http://schemas.xmlsoap.org/ws/2003/05/partner-link/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:client="http://xmlns.oracle.com/SimpleProcess">

</message>
- <portType name="SimpleProcess">

</operation>
</portType>
- <binding name="SimpleProcessBinding" type="tns:SimpleProcess">

</output>
</operation>
</binding>
- <service name="SimpleProcess">

</port>
</service>
- <plnk:partnerLinkType name="SimpleProcess">
- <plnk:role name="SimpleProcessProvider">
<plnk:portType name="tns:SimpleProcess" />
</plnk:role>
</plnk:partnerLinkType>
</definitions>
and my soap client code is as follows
public static void main(String[] args) throws Exception {
     String endpoint =
     "http://ICON-OBCC.asiapacific.hpqcorp.net:9700/orabpel/default/SimpleProcess/1.0 ";
     Service service = new Service();
     Call call = (Call) service.createCall();
     call.setTargetEndpointAddress( new java.net.URL(endpoint) );
call.setOperationName(new QName("http://xmlns.oracle.com/TP", "process"));
String ret = (String) call.invoke( new Object[] { "FFF" } );
     System.out.println("Sent 'Hello!', got '" + ret + "'");
when i execute this i am getting follwoing error on BPEL console
Error - OWS-04005 an error occured for port BPEL_OC4j_SOAP_PROVIDER javx.xml.rpc.JAXRPCException java:lang:NullPointerException
Any indication for resolving this will be great help.
