Those durn customers!

Its a difficult requirement.  Its a platform question more than an RCP 
one as it has to do with starting eclipse and getting parameters into 
it.  Ask in platform newsgroup.

as for starting tomcat server thats easy.  Break out this portion of 
your program into a seperate server.  Perhaps call it through RMI.  That 
way this seperate part can ensure only a single version is running no 
matter how many  are tried to start.

P.S. eclipse also starts an embedded tomat server for Help IIRC.
