hanging on port 4000

Zahid Rahman
I have made some more progress.
I made another change by adding  trust="true"   below verbose="true"
the command  "touch somefile" ran successfully.

It is now hanging here  listening on port 4000.
[sshexec] cmd : java -Xdebug

Re: hanging on port 4000

Zahid Rahman
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.

Re: hanging on port 4000

Zahid Rahman
In reply to this post by Zahid Rahman
 > Caught an exception, leaving main loop due to Socket closed

I got this message after I completed the steps described in the previous

The message is misleading.  There is no exception.  The program completed.
