PI 7.1 Java Mapping using Eclipse

Firstly I apologize if this has been asked before, but after spending an hour searching the discussions I could not find an answer.

About two years ago I found a way (from a SDN blog I believe) on how to setup NWDS to compile Java Mappings for PI 7.1.

My previous computer crashed and I lost that configuration. Now I need to modify a Java mapping and do not recall the process to setup NWDS.

My recollection was that I downloaded a base NWDS package (not the whole CE studio) and then used the Update Site to setup the necessary environment objects (to create PI mappings/JAR) for the Eclipse editor.

I thought this was covered in a blog post. Does this sound familiar to anyone?

Thank you for helping.
