Instead of using Java look into using Python. Python has a PyVISA module that will let you communicate and control test equipment via GPIB, USB and RS232. PyVISA provides bindings to the VISA library and PyVISA and Python are free. Another nice part is that Python is very similar to Matlab in handling vectors, matrices and plotting.
Just google Python and PyVISA and you'll be running in no time.
