Hi everyone,
I'm using the service given in sample03 of the Apache Rampart distro to
get the UserNameToken information at the service level. The service is
given below:
public class EchoService {
MessageContext msgCtx;
public void setOperationContext(OperationContext opContext) throws
AxisFault {
this.msgCtx =
opContext.getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE);
}
public String echo(String arg) {
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
String user = principal.getName();
String passwd = principal.getPassword();
//Authenticate
if("sanjay".equals(user) &&
"wspwd".equals(passwd)) {
//Authentication successful
System.out.println("User was: " + user);
return arg;
} else {
throw new RuntimeException("Authentication
Faliure!!");
}
}
}
}
return arg;
}
}
}//end of EchoService
And my client code is:
public class Client {
private static EndpointReference targetEPR =
new EndpointReference(
"http://localhost:8080/axis2/services/EchoService";);
private static String confPath = "C:\\rampart\\echo";
public static void main(String[] args) throws Exception {
ConfigurationContext ctx =
ConfigurationContextFactory.
createConfigurationContextFromFileSystem(confPath,
confPath + "/conf/axis2.xml");
ServiceClient client = new ServiceClient(ctx,null);
Options options = new Options();
options.setAction("urn:echo");
options.setTo(targetEPR);
client.setOptions(options);
OMElement response = client.sendReceive(getPayload("Hello
world"));
System.out.println(response);
}
private static OMElement getPayload(String value) {
OMFactory factory = OMAbstractFactory.getOMFactory();
OMNamespace ns =
factory.createOMNamespace("http://extract.rampart.apache.org","ns1";);
OMElement elem = factory.createOMElement("echo", ns);
OMElement childElem = factory.createOMElement("param0", null);
childElem.setText(value);
elem.addChild(childElem);
return elem;
}
}//end of Client
However, when I run the client (which is also from the sample03), I get
the following exceptions:
Exception in thread "main" org.apache.axis2.AxisFault: Exception
occurred while trying to invoke service method echo

org.apache.axis2.util.Utils.getInboundFaultFromMessageContext(Utils.java

)
at org.apache.rampart.extract.Client.main(Client.java:33)
Is there a reason for these exceptions? I can't really figure out what's
going wrong because the exceptions doesn't tell me much. In essence,
it's basically a simple EchoService but with the addition of security
processing code. Any ideas on how I should proceed? Cheers.
