No @RolesAllowed available for Webservices

The JEE specification is growing into a nice and easy to use specification. But some features, like Webservices and RolesAllowed, are not good enough yet. To be more precise. @RolesAllowed is not supported for plain Webservices (not doubling as EJB’s) until version 3.0 in the Servlet Specification.

Webservices with Spring and Castor

Monday, August 17th, 2009

Today, webservices are used primarily to expose some services of an application to the outside world. There are a lot of tools available to consume webservices. Tools like Mule, Axis and Spring.
This article describes a method of exposing Java services as webservices. The technique’s / tools used to accomplice this are; Java, Spring and Castor.
There are many other tools available, like Axis, to expose java services as webservices. The reason I used Spring and Castor is the simplicity in creating webservices. Spring takes care of all boilerplate coding and Castor’s mapping capability takes care of the Object <-> XML mapping without the need to generate any java objects the way Axis does. This way you have clean java code, supported with configuration in Spring and a clean Castor mapping to expose your service as a webservice.
