Hi Gurus,

I have a Q :

In ABAP we do the dictionary / repository modification adjustments through SPDD/ SPAU ..How do we

accomplish JAVA modification Adjustments ..I mean either through Visual Admin / ConfigTool or some

other tool ..but, what exactly is the tool and how we do it ?

Useful answeres would ALWAYS be rewarde without failure..

Many Thanks in Advance,
