 |
|
I am just about finished with my first java application, and am in the
process of testing the deployment on a windows box as well as a UNIX box. I
have research / have created an executable jar file and attempted to execute
it in a UNIX environment and got the error below..I created the application
in JBuilder 8 personal..do I need to add a specific library to run this GUI?
Exception in thread "main" java.lang.InternalError: Can't connect to X11
window
server using ':0.0' as the value of the DISPLAY variable.

168 try {

Thanks, any assistance is greatly appreciated!

Try running just the jar file first. I have had problems with the native bin |
builder across differing versions of UNix as well. If the jar runs fine,
then the Native exe/bin builder is the culrpit. If the jar has problems
running, something else is amiss.
run the jar with the verbose on and get the full stack dump. That may help
you determine where the problem is.
BTW, what JDK are you using and deploying to?

running 1.4.1 and deploying to 1.4.2......its seems as though I had a issue
with my X server.....running the application from a unix environment worked
fine, but testing it through a pc is when I had problems.....fixing this
corrected my issue....thanks!

Delali,
the error you are seeing points more to an environment problem.
for Unix you need to specify the DISPLAY on which your windows are to be
shown.
depending on the shell you are using to start your jar file try the
following:
+ on bash/sh/ksh: export DISPLAY=<your host name>:0.0
+ on csh: setenv DISPLAY <your host name>:0.0
you also might need to allow access to your X11 server:
xhost +<your host name>

Make sure that you aren't trying to execute this through a shell that |
doesn't have X associated with it (i.e. telnet or SSH).
Also, just try running it via the java -jar and get that working first.
