Hi, I am using WSS4J for invoking a secured web service. The request XML generated by my client is almost the same as the sample provided by the Service Provider. The only difference is an additional "wsu:Id" attribute defined for <ds:Signature> tag.
Here's what my code is generating: <ds:SignatureId="Signature-22"xmlns:ds="http://www.w3.org/2000/09/xmldsig#";> Here's what the Service Provider is expecting <ds:SignatureId="Signature-16906910"wsu:Id="Id-8819824"xmlns:ds="http://www.w3.org/2000/09/xmldsig#"xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd";> I suspect that due to this missing tag I am getting the exception, pasted below, when I am try to invoke the service. I am not able to figure out how the highlighted tag will get added to the XML. Is there any configuration/attribute that I can change while invoking the WSSecSignature.build()? Gone through the API documentation and the code but could not find anything specific to this. Will appreciate any help/guidance in resolving this. -------------------------------------------- Caused by: java.lang.NullPointerException at org.apache.ws.security.util.WSSecurityUtil.findElementById(WSSecurityUtil.java:298) at org.apache.ws.security.util.WSSecurityUtil.getElementByWsuId(WSSecurityUtil.java:438) at org.apache.ws.security.processor.SignatureProcessor.verifyXMLSignature(SignatureProcessor.java:297) at org.apache.ws.security.processor.SignatureProcessor.handleToken(SignatureProcessor.java:79) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:279) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:201) at org.apache.rampart.RampartEngine.process(RampartEngine.java:71) at org.apache.rampart.handler.RampartReceiver.invoke(RampartReceiver.java:69) at org.apache.axis2.engine.Phase.invoke(Phase.java:381) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:518) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:483) at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:319) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:247) ... 12 more ---------------------------------------------- Thanks, Rameshwer Jangra
