Anyone using sap2java plug-in for eclipse ?

I found an eclipse plug-in that generates java classes by specifying an rfc or bapi (http://eclipsesap2java.sourceforge.net/). I tried it on the bapi BAPI_BUPA_ADDRESS_CHANGE and it generated 30 or so java classes...it scared the heck out of me !!

I was wondering if anybody was using this tool and what their impressions were ?

Also, are there other tools such as these that someone wants to recommend.

Thanks in advance,

Mark
