Java Development Tools

Hi ,
I am trying to invoke a Purchase Order Webservice deployed on Oracle Apps Server.We can find that in SOA Gateway resp of Oraacle ERP.
I am using Jdev and created a java project which invokes the webservice proxy.Now in the client class I have added all the required data to invoke the ws
like responsibility , security group , NLS Language etc.
But when I run that then I get following error:

ava.rmi.RemoteException: SOAPFaultException - FaultCode [{http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd}InvalidSecurity] FaultString [Missing <wsse:Security> in SOAP Header] FaultActor []No Detail; nested exception is:
weblogic.wsee.jaxrpc.soapfault.WLSOAPFaultException: Missing <wsse:Security> in SOAP Header
at com.sun.java.PO_CHANGE_API1_S_PortType_Stub.uPDATE_PO(PO_CHANGE_API1_S_PortType_Stub.java:90)
at com.sun.java.PO_CHANGE_API1_S_PortTypePortClient.uPDATE_PO(PO_CHANGE_API1_S_PortTypePortClient.java:220)
at com.sun.java.PO_CHANGE_API1_S_PortTypePortClient.main(PO_CHANGE_API1_S_PortTypePortClient.java:87)
Caused by: weblogic.wsee.jaxrpc.soapfault.WL

I know that we have to add the username and password as ws security but not sure how to add that and also where we can create those policies. Any pointer would be helpful.

The jdev client code is as follows

public class PO_CHANGE_API1_S_PortTypePortClient {
private PO_CHANGE_API1_S_PortType _port;
private List<CredentialProvider> _credProviders;

}
