Hi Santhosh,
I'm not sure I quite follow the servlet part, as I don't know anything about
java. But shouldn't they be connecting with display set to their local IP as
in "192.168.1.10:0" otherwise it may be getting interpretted as trying to
display on the web servers localhost.
You probably don't need to worry about lock files, but if there are lock
files, they will be in /tmp.
>From one of your errors:
Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.
If you have an X server running, it will have /tmp/.X0-lock, so you should
quit X, then from a console, check that no .X0-lock, .X1-lock... files remain
in /tmp. However, if an Xserver was running all along, and you were trying to
launch a second, there will only be the one lock file, which will be for your
running X session. If you wanted to start a second X session on the same box,
you would use display 0:1, which should creat a .X1-lock file.
