JUnit.org Resources for Test Driven Development

I want to know how to run “junit plugin tests” from command line for. Even after following various posts on the net I am unable to do the task. I want that from the command line eclipse opens, runs junit plugins tests on top of it and then saves the results in either pdf or html format. I see documentation of JUnit 3.x. It says how t run JUnit tests from command line but nothing is mentioned on how to run JUnit plugin tests.
I am using Eclipse Version 3.4.0 and Junit3 tests.

Please provide guidelines and complete steps for the same.Thanks in advance.
