A bundle project producing JAX-RS RI bundles. The primary artifact is an "all-in-one" OSGi-fied JAX-RS RI bundle (jaxrs-ri.jar). Attached to that are two compressed JAX-RS RI archives. The first archive (jaxrs-ri.zip) consists of binary RI bits and contains the API jar (under "api" directory), RI libraries (under "lib" directory) as well as all external RI dependencies (under "ext" directory). The secondary archive (jaxrs-ri-src.zip) contains buildable JAX-RS RI source bundle and contains the API jar (under "api" directory), RI sources (under "src" directory) as well as all external RI dependencies (under "ext" directory). The second archive also contains "build.xml" ANT script that builds the RI sources. To build the JAX-RS RI simply unzip the archive, cd to the created jaxrs-ri directory and invoke "ant" from the command line.

There is a newer version: 3.1.9

/**
 * Interceptor for method validation processing.
 *
 * Allows to override the default Jersey behaviour. By default, the Jersey runtime throws a
 * {@link javax.validation.ValidationException} or one of its subclasses,
 * that gets mapped to a HTTP 400 response, if any validation issues occur. In such case
 * the actual resource method does not get invoked at all.
 * 
 * Validation interceptor implementation allows to e.g. swallow the {@link ConstraintViolationException}
 * and handle the validation issues in the resource method. It is also possible to tweak
 * validated components. This could be utilized in case of proxied resources,
 * when field validation is not possible on a dynamic proxy, and the validator requires
 * the original delegated instance.
 * 
 * 
 * Each validation interceptor implementation must invoke proceed
 * method on provided interceptor context as part of interception processing.
