Hi,
Problem description: I have a service method that expects a UsernameToken in
the header. Right now am sending the password as plain text over a secure
transport. The client side handler adds this UsernameToken into the soap
envelope.
If a soap fault is thrown from this service method, I get a Null pointer at the
client side. I found it strange, bcos when I see the outgoing soap envelope
from the server, it contains proper soap fault details.
Enviroment: Axis 1.4, Jboss 4.0.1 sp1, WSS4J 1.5.1
Client side request handler adds usernametoken in this manner
package client;
import org.apache.axis.AxisFault;
import org.apache.axis.Message;
import org.apache.axis.MessageContext;
import org.apache.axis.handlers.BasicHandler;
import org.apache.axis.message.SOAPEnvelope;
import org.apache.axis.message.SOAPHeaderElement;
import org.apache.axis.session.Session;
import org.apache.axis.transport.http.HTTPConstants;
import org.apache.ws.security.WSConstants;
import org.apache.ws.security.message.WSSecHeader;
import org.apache.ws.security.message.WSSecUsernameToken;
import org.w3c.dom.Document;
public class RequestHandler extends BasicHandler {
public void invoke(MessageContext messageContext) throws AxisFault {
MessageContext currContext = messageContext.getCurrentContext();
Message message = currContext .getRequestMessage();
SOAPEnvelope envelope = message.getSOAPEnvelope();
try {
Document doc = envelope.getAsDocument();
WSSecHeader secHeader = new WSSecHeader("",false);
secHeader.insertSecurityHeader(doc);
String username = "user1";
String password = "password";
WSSecUsernameToken builder = new WSSecUsernameToken();
builder.setPasswordType(WSConstants.PASSWORD_TEXT);
builder.setUserInfo(username, password);
builder.prepare(doc);
builder.appendToHeader(secHeader);
envelope.addHeader(new
SOAPHeaderElement(secHeader.getSecurityHeader()));
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
This is the out going SOAP envelpe from client
