Spring 3, Spring Web Services 2 & LDAP Security.

This year started on a good note, another one of those "the deadline won't change" / "skip all the red tape" / "Wild West" type of projects in which I got to figure out and implement some functionality using some relatively new libraries and tech for a change, well Spring 3 ain't new but in the Java 5, weblogic 10(.01), Spring 2.5.6 slow corporate kind of world it is all relative.
Due to general time constraints I am not including too much "fluff" in this post, just the nitty gritty of creating and securing a Spring 3 , Spring WS 2 web service using multiple XSDs and LDAP security.
The Code:

The Service Endpoint: ExampleServiceEndpoint
This is the class that will be exposed as web service using the configuration later in the post. The Code: CustomValidationCallbackHandler

This was my bit of custom code I wrote to extend the AbstactCallbackHandler allowing us to use LDAP. As per the comments in the CallbackHandler below, it's probably a good idea to have a cache manager, something like Hazelcast or Ehcache to cache authenticated users, depending on security / performance considerations.
The Digest Validator below can just be used directly from the Sun library, I was just wanted to see how it worked.


The service config:
The configuration for the Endpoint, CallbackHandler and the LDAP Authentication manager.
The Application Context - Server Side:
The Security Context - Server Side:

The Web XML:
Nothing really special here, just the Spring WS MessageDispatcherServlet.
The client config:
To test or use the service you'll need the following:
The Application Context - Client Side Test:

The Security Context - Client Side:

As usual with Java there can be a couple little nuances when it comes to jars and versions so below is part of the pom I used.
The Dependencies:

Wordballs Release

Finally, Wordballs is live! 
My latest physics based word game. Please check it out if you have an iOS device, and let your friends know. 

It's Free (with ads) and 16mb to download. 
Please take a couple seconds to rate it as well, it will be much appreciated

This game actually took me some time to do. Crazy deadlines and some nasty hours at work meant for some slow going and some very late nights at times. 

I would just like to thank the teams from:

Chipmunk Physics
Cocos 2D

Without their awesome libraries / code this Wordballs would have been impossible.
