It's sorted. I get this message because I was running in debug mode and I had a break point in main ().
So I had to go to eclipse main menu Run - > debug configuration -> Under remote java application -> select configuration file created earlier -> debug button. I was then prompted by eclipse to switch debug perspective . Then I pressed f6 (step over). The program completed. SUCCESS. So now I have taken the raspberry pi java programs found here www.pi4j.com and now I am running them in eclipse IDE remotely as a headless rasberry pi. I could run do headless graphic development through VNC viewer. However I would be using the pi processor for compilation. Using remote java eclipse the benefit is I am doing the compilation on my laptop and the running on raspberry pi. Thank you for all the responses.
