Error when obtaining UsernameToken information from a different class.

[Sanjay Vivek <Sa...@newcastle.ac.uk>]

Hi all,

I've a policy based service that returns the UsernameToken information
of the authenticated user. However, I wish to obtain the UsenameToken
information from a separate class as shown below:

public class PolicyEchoService {
	
	public String echo() {
        
        AuthUser authuser = new AuthUser();
        String user = authuser.getAuth();
        
        return("The authenticated user was" + user);
        
	}
}//end of PolicyEchoService


Where the AuthUser.java:


public class AuthUser {
	
	public String getAuth() {
		
	  //user variable
        String user=null;
       
        
        MessageContext msgCtx =
MessageContext.getCurrentMessageContext();
        Vector results = null;
        if ((results = (Vector) msgCtx
                .getProperty(WSHandlerConstants.RECV_RESULTS)) == null)
{
            System.out.println("No security results!!");
            throw new RuntimeException("No security results!!");
        } else {
            System.out.println("Number of results: " + results.size());
            for (int i = 0; i < results.size(); i++) {
                WSHandlerResult rResult = (WSHandlerResult)
results.get(i);
                Vector wsSecEngineResults = rResult.getResults();

                for (int j = 0; j < wsSecEngineResults.size(); j++) {
                    WSSecurityEngineResult wser =
(WSSecurityEngineResult) wsSecEngineResults.get(j);
                    if (wser.getAction() == WSConstants.UT
                            && wser.getPrincipal() != null) {
                        
                        //Extract the principal
                        WSUsernameTokenPrincipal principal =
(WSUsernameTokenPrincipal)wser.getPrincipal();
                        
                        //Get user/pass
                        user = principal.getName();
                                                
                    }
                }
            }

            return user;
        }

    }//end of getAuth

}// end of AuthUser

So basically my PolicyEchoService.aar is:

 +META-INF
   	-services.xml

 +policy
  	- PolicyEchoService.class
  	- AuthUser.class
  	- PWHandler.class


However, when I try to call the service with my client, I get the
following exceptions:

Exception in thread "main" org.apache.axis2.AxisFault: Message Receiver

What am I doing wrong? Any pointers will be very helpful. I've also
provided my client below. Cheers.

public class Client {

    private static EndpointReference targetEPR = 
        new EndpointReference(
 
"http://pod.ncl.ac.uk:8083/axis2/services/AltPolicyService");
	
    private static String confPath = "C:\\rampart\\policy";
		
	
    public static void main(String[] args) throws Exception {

        ConfigurationContext ctx = 
        	ConfigurationContextFactory.
 
createConfigurationContextFromFileSystem(confPath,null);
    	
        ServiceClient client = new ServiceClient(ctx, null);
        Options options = new Options();
        options.setAction("urn:echo");
        options.setTo(targetEPR);
        options.setProperty(RampartMessageData.KEY_RAMPART_POLICY,
loadPolicy( confPath + "/conf/policy.xml"));
        
                
        //this username is authenticated against the PWHandlerClient
class
        options.setUserName("sanjay");
        client.setOptions(options);
        
        client.engageModule("addressing");
        client.engageModule("rampart");
        
        OMElement result = client.sendReceive(getPayload());
        
        String response = result.getFirstElement().getText();
        System.out.println(response);    
    }
    
    private static Policy loadPolicy(String xmlPath) throws Exception {
        StAXOMBuilder builder = new StAXOMBuilder(xmlPath);
        return PolicyEngine.getPolicy(builder.getDocumentElement());
    }
    
    
    private static OMElement getPayload() {
        OMFactory factory = OMAbstractFactory.getOMFactory();
        OMNamespace ns =
factory.createOMNamespace("http://policy.rampart.apache.org","ns1");
        OMElement elem = factory.createOMElement("echo", ns);
        
        return elem;
    }
    
}
