Hi,
do you use some graphic functions in your project? If so,
you should add the following parameter to Tomcat startup:
-Djava.awt.headless=true

window server using ':0.0' as the value of the DISPLAY
variable. "

Please adv.

The material George gave you is really good. Do you have X11 installed,
even if not running? I am not a Solaris guy, so don't know what that may
mean in that context.

Thanks Micael. Tried the same thing and got the same results.
Looks like Catalina/Tomcat is indeed using headless mode but
it's not working with my Java (1.4) and operating system (SunOS 5.6).
I'm presuming you're using this to create/generate graphics in a
servlet ? Do you mind posting sample J
I added the headless flag to catalina.sh as follows:
# - Execute The Requested Command -

May I ask, how you did this ? I've also encountered
JNI_OnLoad errors runing on Solaris due, I suspect, the lack of
XWind

Yep: Done correctly, this is probably the more 'correct' solution, but,
and I'm pro
oesn't have one.
We always used to use this on sun E250s without a display adapter, but now
we use headless as it's more reliable.

Yep: Done correctly, this is probably the more 'correct' solution, but,
and I'm probably opening myself to a lot of flamebait, but I do suspect
that using something like Xvfb might give some advantages that using
headless won't. For example, and I'm just guessing, but I think that
'headless' is pur
what it needs to work (which abstract classes and
interfaces to implement).

Chris.

For me the easiest thing was just to provide the right command line options
(java.awt.headless=true) when I started up Tomcat.

er a guess you'll need to run tomcat in a 'headless' JVM.
To do that add :
-Djava.awt.headless=true
To the :
CATALINA_OPTS
environment variable.

I can think of cases where headless isn't enough, but if you are that
creative, it deserves another topic ;-)
