Question

I have Axis2 web services running in an Application Server (like JBoss, WebSphere and Weblogic) and till now I am passing the user details within a request and authenticating the user before processing it.

The next step is that I want to delegate the authentication bit to the Java EE Application Server and once authenticated the application server should pass the UserPrinciple which I will be using as context to execute the request.

I am not sure if I have asked the question correctly? I think I am mixing the WebContainer authentication with WS-Security stuff.

Can anyone please point me to the right direction with some documentation which I can refer as start-up guide.

Answer 1

OK, I have tried a solution and it worked to some extent. Here are details;

Created TestService with following services.xml

<serviceGroup>
    <service name="TestWebService" scope="application" targetNamespace="http://TestServiceWs"> 
        <schema schemaNamespace="http://TestServiceWs"/>
        <description>Test POJO Axis2 AAR deployment</description>
        <parameter name="ServiceClass">test.TestServiceWS</parameter>
        <messageReceivers>
            <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
                class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"/>
            <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
                class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
        </messageReceivers>
    </service>

    <module ref="rampart" />

    <parameter name="InflowSecurity">
      <action>
        <items>UsernameToken Timestamp</items>
        <passwordCallbackClass>test.PWHandlerServer</passwordCallbackClass>
      </action>
    </parameter>
</serviceGroup>

Implemented PWHandlerServer.java

package test;

import java.io.IOException;

import javax.security.auth.callback.Callback;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.callback.UnsupportedCallbackException;

import org.apache.ws.security.WSPasswordCallback;

public class PWHandlerServer implements CallbackHandler {

    // the username and password we expect incoming WS calls to use
    private String user = "wsuser";
    private String pwd = "wspwd";

    public void handle (Callback[] callbacks) throws IOException, UnsupportedCallbackException {
        for (int i = 0; i < callbacks.length; i++) {
            if (callbacks[i] instanceof WSPasswordCallback) {
                WSPasswordCallback pc = (WSPasswordCallback) callbacks[i];
                System.out.println("identifier: "+pc.getIdentifer()+", usage: "+pc.getUsage());

                if (pc.getUsage() == WSPasswordCallback.USERNAME_TOKEN) {
                    // for passwords sent in digest mode we need to provide the password,
                    // because the original one can't be un-digested from the message

                    // we can throw either of the two Exception types if authentication fails
                    if (! user.equals(pc.getIdentifer()))
                        throw new IOException("unknown user: "+pc.getIdentifer());

                    // this will throw an exception if the passwords don't match
                    pc.setPassword(pwd);

                } else if (pc.getUsage() == WSPasswordCallback.USERNAME_TOKEN_UNKNOWN) {
                    // for passwords sent in cleartext mode we can compare passwords directly

                    if (! user.equals(pc.getIdentifer()))
                        throw new IOException("unknown user: "+pc.getIdentifer());

                    // we can throw either of the two Exception types if authentication fails
                    if (! pwd.equals(pc.getPassword()))
                        throw new IOException("password incorrect for user: "+pc.getIdentifer());
                }
                // If everything is OK then set the context and move on
                TestRequestContext ctx = new TestRequestContext(pc.getIdentifer());
                TestRequestContext.setRequestContext(ctx);

            } else {
                throw new UnsupportedCallbackException(callbacks[i], "Unrecognized Callback");
            }
        }
    }
}

Implemented TestRequestContext

package test;


class TestRequestContext {
    private final static ThreadLocal<TestRequestContext> currentContext = new ThreadLocal<TestRequestContext>();

    public static void setRequestContext(TestRequestContext context) {
        currentContext.set(context);
    }

    public static TestRequestContext getRequestContext() {
        return currentContext.get();
    }

    public static void clearRequestContext() {
        currentContext.remove();
    }

    private String userPrincipal;

    public TestRequestContext(String principal) {
        this.userPrincipal = principal;
    }

    public String getUserPrincipal(){
        return this.userPrincipal;
    }
}

Now I should be able to access my TestRequestContext.getUserPricipal() in my web service class and pass it on DB for transaction and switching a security context. The only problem is when I am trying to access the service via SoapUI its giving me following exception;

Within SoapUI, I am simply using ‘Auth’ tab to set username and password and invoke? do I need to setup anything else before invocation.

Also, the approach to use ThreadLocal is correct or I can access the principle some otherway as well?

Thanks.
