Adventures in Grails – WS-Security Part 1

The next step in rewriting the application was to secure the web services with WS-Security. In this post I get a grails version of the xfire wss example of User Token Authentication up and running. To do this I use (of course) the grails xfire plugin.

After creating a grails project and installing the xfire plugin, the first thing to do is to configure the inHandlers:

to do this add the following to the doWithSpring closure in XfireGrailsPlugin.groovy

 

"xfire.passHandler"(org.codehaus.xfire.demo.PasswordHandler) { bean ->
        }

"xfire.DOMhandler"(org.codehaus.xfire.util.dom.DOMInHandler) { bean ->
        }

"xfire.WSS4JHandler"(org.codehaus.xfire.security.wss4j.WSS4JInHandler) {
    properties = ["passwordCallbackRef":ref("xfire.passHandler"),
                  "action":"UsernameToken"]
        }
"xfire.ValidateUserTokenHandler"(org.codehaus.xfire.demo.ValidateUserTokenHandler) {
        }

 ValidateUserTokenHandler and PasswordHandler are part of the example code distributed with xfire. I just copied them into the correct package in src/java/ in this simple grails app. And then add the inHandlers to the org.grails.xfire.ServiceBean

 

inHandlers = [ref("xfire.DOMhandler"),
              ref("xfire.WSS4JHandler"),
              ref("xfire.ValidateUserTokenHandler")]

 

See the complete listing for doWithSpring at the end of this post. Now any service you expose with xfire will require (and print) a username and password in a WSS UsernameToken header. The simple service I used to test this is:

class TestService {

    static expose=['xfire']

    boolean transactional = true

    String serviceMethod() {
       return "You did it!!!"
    }
}

 I use soapUI to test, here is the request it generated:

1 foo
2 bar

This is obviously not a perfect solution. You may not want to secure all the web services in your project or at least not all in the same way. After I finish with this project I will have a more general solution to contribute to the grails xfire plugin.But first, I need to do something with the user credentials I am now receiving. Next up, integrating with acegi through the grails acegi plugin…
