AIX

Hello Folks

We have following software installed on our AIX box

X11.vfb - Virtual Frame Buffer Software

We also see its process running

Code:

root 528406 1 0 06:27:18 - 0:00 /usr/bin/X11/X -force -vfb -x abx -x dbe -x GLX :1

Following is the o/p of 'lslpp'

Code:

X11.vfb 5.3.0.50 /usr/lpp/gai/vfb/loadddx
/usr/lib/drivers/rcm_stub
/usr/lpp/gai
/usr/lpp/gai/vfb
/usr/lib/methods/load_rcm_stub_ext
/usr/lpp/gai/vfb/loadAbx

We get following error in logs:

Code:

[4/27/10 7:11:58:739 EDT] 00000037 WebApp E SRVE0026E: [Servlet Error]-[action]: java.lang.NoClassDefFoundError: sun/awt/X11GraphicsEnvironment

We are hitting a web app from browser and it tries to render a report which is to be opened/saved in MS-Excel.Every time we hit this functionality we get above error.

Any ideas/suggestions pls.

Where is your $DISPLAY pointing at?

we tried setting it as:

Code:

export DISPLAY=localhost:0.0

but the error is same....

where should we set DISPLAY variable ? i had it set in my user's .profile.

You use :1 as display for your X VFB. You set your $DISPLAY to *:0.0 where the 1st zero tells which X server and the second the display. Maybe you got a mismatch there.
My guess is, that the correct place to export the $DISPLAY will be most probably the environment where you start your webserver, where the JAVA app runs in that uses the VFB, ie. when you start it make sure the correct $DISPLAY is exported.

To check if your VFB is running correct etc., check out this:
IBM - The X Virtual Frame Buffer

Else there is a lot of posts in other forums etc. relating to the error message you get and most point to the thing described up there.

Issue resolved....!!!

We just had to set DISPLAY variable at the right place ; and our sys admin folks forgot to reboot the server once after installing VFB.

We bounced the server once and there it was....it started working fine.

Sorry for responding late and thanks for responding to my thread.
