Hi,
I'm attempting to read the username from the soap header ws-security
block in my web service, using the following code
(modified from the snippet shown at
http://ws.apache.org/wss4j/apidocs/org/apache/ws/axis/security/package-summary.html):
String user = null;
try {
MessageContext context =
MessageContext.getCurrentContext();
Vector recvResults = (Vector)
context.getProperty(WSHandlerConstants.RECV_RESULTS);
WSHandlerResult result = (WSHandlerResult)
recvResults.get(0);
Vector results = result.getResults();
WSSecurityEngineResult wsseResult =
(WSSecurityEngineResult) results.get(0);
String DN = wsseResult.getPrincipal().getName();
user = DN.substring(13, DN.indexOf(','));
} catch (Exception e) {
e.printStackTrace(System.err);
}
However, I get an NPE here:
String DN = wsseResult.getPrincipal().getName();
Here's the stack trace:
java.lang.NullPointerException

I am able to get debug output for WSSecurityEngine (handler output):
- enter processSecurityHeader()
- Processing WS-Security header for '' actor.
- Found UsernameToken list element
- UsernameToken user test
- UsernameToken password CcgmjRKPSS/vVrETPlpGWgwsSQg=
- UsernameToken callback password <removed>
- Found Timestamp list element
- Preparing to verify the timestamp
- Current time: 2005-11-05T03:06:47Z
- Timestamp created: 2005-11-05T03:06:47Z
- Timestamp expires: 2005-11-05T03:11:47Z
- Validation of Timestamp: Everything is ok
but not for WSS4JHandler, for the code snippet above. Both are set
to DEBUG in log4j.properties.
If I use the code snippet at the url above, the NPE occurs at:
WSSecurityEngineResult eResult = (WSSecurityEngineResult) hResults.get(j);
Finally, I am seeing the "java.lang.NoSuchFieldException:
m_functions" error in the log, which still persists despite
creating the $JAVA_HOME/jre/lib/endorsed directory and placing
xalan-2.6.0.jar there.
Thanks in advance for any help.
