R help - Apr 2008 - Problem with graphic exhibition in Java using JRI

Dear all
I am working on a Java class which calls R functions. To do that, I use JRI.
Everything works fine up to now. The only problem I have is the following:
when I call the command plot(….) from java, a blank "R Graphics"
window
appears and if I click on it the program does not answer any more. Could
anyone please tell me what should I do to fix this problem?

Thanks in advance.
