Unix won't display images when X11 is running

Post by Hosoi » Wed Jun 11, 2003 11:57 pm

Hi,

I am getting the usual X11 problem when running my Application consisting of JSP's, Servlets and EJB's in Webspshere on Unix.

X11 is running on the server so I can't understand why the image can't be generated.

So firstly can this be done using Websphere?

If so has Websphere been configured incorrectly? If so does anybody know what needs to be done.

Ta very much,

Hosoi

I have deployed an enterprise application from development people who incorporated jfreechart functionality on WAS 4.05 - HP UX and charts are now working. Can give you more info if you are still interested.

Hosoi,

I am facing the similar problem on AIX environment. Can you tell me how did you displayed images?
Actually ia m unable to write image to JPEG in AIX. Any idea why this is happening.

try "headless" setting on Java command line

I had a similar problem on a Sun box, the fix was to
use JDK1.4 and call java with the following option :

"-Djava.awt.headless=true"

AIX / JDK 131 / Websphere 403, and X11 DISPLAY problem

:D
My final working solution for AIX, after exhausting all possible settings/configurations with PureJavaAWT, is XVFB. If you MUST get a solution, check out this link for details:

Best luck!

Hi phamdinhnguyen

Did you also using WebSphere with 3-tier. ie. Separate WebServer, plugin.xml to communicate with AppServer. After I installed Xvfb in linux, and done some test with xclock, it works fine with the xclock, but not with the browser ????

Cheers
Seri

Seri,
Sorry I didn't answer you sooner.

Our development and deployment have both WebServer and AppServer in the same box. If you have them in separate boxes, my strong feeling is that you must have XVFB installed where your AppServer resides, since this is where your Servlet codes make graphic API calls.
I could be wrong though!

Good luck!
