Obtaining the PID of a running application and the value itself happens to be one of those things that is not going to translate well from platform to platform. AFAIK there isn't a reliable way in java to get that kind of information . . . -- -------------------------------------------- Chris Salch Programmer/Analyst LeTourneau University
