Opening an existing process - linux

Question

I am using Eclipse in Linux through a remote connection (xrdp). My internet got disconnected, so I got disconnected from the server while eclipse was running.
Now I logged in again, and I do the "top" command I can see that eclipse is running and still under my user name.
Is there some way I can bring that process back into my view (I do not want to kill it because I am in the middle of checking in a large swath of code)? It doesnt show up on the bottom panel after I logged in again.
Here is the "top" output:

It is a long shot, but you could try this little program from this thread
#include <stdio.h>
#include <stdlib.h>
#include <X11/Xlib.h>
int main(int argc, char **argv)
{
if ( argc != 2 ) {
printf("Usage:\n\ttotop <window id>\n");
return 1;
}
Display *dsp = XOpenDisplay(NULL);
long id = strtol(argv[1], NULL, 16);
XRaiseWindow ( dsp, id );
XSetInputFocus ( dsp, id, RevertToNone, CurrentTime );
XCloseDisplay ( dsp );
return 0;
}
You can compile it with:
$ c++ totop.cpp -L/usr/X11R6/lib -lX11 -o totop
I assumed that you saved it in "totop.cpp".
It has problem I do not know how to fix:
if window is in another virtual desktop this program doesn't work.
Here another question rises: how to send window to current desktop?
You can get window id using xwininfo.
A little script using this program used to call Eclipse:
#!/bin/bash
if ps -A | grep eclipse; then # if Eclipse already launched
id=$(xwininfo -name "Eclipse" | grep id: | awk "{ print \$4 }")
totop $id
else # launch Eclipse
eclipse
