Sling

After reading Having “fun” with JSR-303 Beans Validation and OSGi + Spring DM, I thought I would attempt to bootstrap JSR-303 Beans Validation in Spring in a Sling OSGi container.  Unfortunately, a few changes have been made to the Hibernate API since Magnus' articles, so a few updates to his version are required.  Additionally, I want to enable JSR-303 Beans Validation in the Sling/Spring MVC environment I previously wrote about.  This presented a few additional challenges, so I'll also walk through the steps to enable JSR-303 Beans Validation in a Spring MVC application context running within a Sling OSGi container so that you can use JSR-303 Beans Validation as described in the Spring documentation.

It is sometimes desirable to run Spring MVC within a Sling container. However, since Sling is a web application, you may not be able to utilize the features within Spring Dynamic Modules and drop a WAR file within the container. In this case, you need to create an application which will bootstrap the Spring Web container within the Sling context.
