Get the source code for the Jazz Plain Java Client

Most, if not all, of the JARs in the PJC (Plain Java Client) are in RTC itself; they are plugins too.

One way to do plain Java development with the PJC and see source is cheat - pretend you do plug-in development - but don't.

Gory details (it nets out as a simple trick) can be seen here:

More info on the SDK is here - I've not caught up with all these links bu I'm sure its good stuff.

In the download JazzPlainJavaClient-1.0.1.1GA.zip there is a readme that says

"The source for the Jazz client libraries can be downloaded from the jazz.net
downloads page."

I couldn't find the source, where exactly is it located?

You can find it on the wiki:
