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.
