R and Java

I am a grad student and am working on a project where i need to integrate
java and R. I have a front end in java and i need to call R functions and
be able to dispaly the plots and graphs produced by R on my java front end.
I came across some tools like SJava and rserve...but am not sure which best
suits my application. Your suggestion will be really helpful.

	The only valuable choice to integrate java and R is rserve.

	With RSjava,  data don't persist between 2 two commands, so you can't set a 
variable in R from java in one instruction and re-use this data in the next 
instruction.

	Rserve is an client/server library, client is pure java (you can easily 
deploy it  on *nix and Windows) and each connection has its own object space 
in R (only under *nix).
