R help - Oct 2007 - know java version

Dear list,
My R program has to deal with a 3rd party java program.
I would like to know, automatically, which version
of java is used when both programs are speaking together.
Does anybody have an idea how to obtain such info from R ?
Thanks
Vincent

If you use the java version fom the classpath you can type inside R:

system("java -version") 
or type "java -version" in the shell or console.
