Subject Axis2/Java 1.5.1 and Rampart 1.4 (no SoapFault returned)
Date Mon, 09 Nov 2009 21:25:01 GMT

Hi,

we use a service with a plain userid/password. We use RAMPART to deal with
this.

In case the clients passes a wrong userid or password (or none at all) we
get an ugly NullPointerException (see below) . No SOAP Response is returned
(we check with SOAPMonitor).

This is of course very inconvenient for 3rd parties wishing to use our
services.

Is this a known 'bug' and is there a workaround ?

Our Callback handler is:

    public void handle(Callback[] callbacks) throws IOException,
            UnsupportedCallbackException {
        WSPasswordCallback pwcb = null;

        for (int i = 0; i < callbacks.length; i++) {
            pwcb = (WSPasswordCallback)callbacks[i];
            String id = pwcb.getIdentifer();
            LOGGER.info("PWCBHandler id: " + id + " PasswordType: " +
pwcb.getPasswordType());

            // Check if password is plain text
            if (pwcb.getUsage() ==
WSPasswordCallback.USERNAME_TOKEN_UNKNOWN) {
              if(!Admin.username.equals(id) || !Admin.password
.equals(pwcb.getPassword())) {
                LOGGER.info("PWCBHandler id: " + id + " Invalid password: "
+ pwcb.getPassword());
                throw new IOException(callbacks[i] + " ... check failed");
              }
            }
        }
        
    }

The error is the Tomcat logging is:

SEVERE: Servlet.service() for servlet AxisServlet threw exception
java.lang.NullPointerException
