I've got the following exception when I've edited my profile to upload an avatar on jforum.net. Guess what? I think you've forgot to run java in headless mode

It's still the same. Try changing tomcat startup scripts so java is started in headless mode:


[... stuff ...]
elif [ "$1" = "start" ] ; then

shift
touch "$CATALINA_BASE"/logs/catalina.out
if [ "$1" = "-security" ] ; then
echo "Using Security Manager"
shift
"$_RUNJAVA" $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
-Djava.security.manager \
-Djava.security.policy=="$CATALINA_BASE"/conf/catalina.policy \
-Dcatalina.base="$CATALINA_BASE" \
-Dcatalina.home="$CATALINA_HOME" \
-Djava.io.tmpdir="$CATALINA_TMPDIR" \
-Djava.awt.headless=true \
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_BASE"/logs/catalina.out 2>&1 &

if [ ! -z "$CATALINA_PID" ]; then
echo $! > $CATALINA_PID
fi
else
"$_RUNJAVA" $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
-Dcatalina.base="$CATALINA_BASE" \
-Dcatalina.home="$CATALINA_HOME" \
-Djava.io.tmpdir="$CATALINA_TMPDIR" \
-Djava.awt.headless=true \
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_BASE"/logs/catalina.out 2>&1 &

if [ ! -z "$CATALINA_PID" ]; then
echo $! > $CATALINA_PID
fi
fi
[... stuff ...]

Well. headless gives another exception.. the problem is how I'm manipulating the images.. Java expects a valid screen to get properties from.. as am not much experiencied with image processing, the code is a mess :?

Suggestions?

well, I fixed that..

instead of doing



I'm just doing



I don't know if this approach is the best, but is sooooooo faster..

Rafael
ps: when I changed this code, the headless thing worked.. thanks

Sorry I was offline, I could point you to some code about this. I have a hand-made photogallery at http://dan.solutions.lv/photoz/ which does some image-work too. Well cool if you solved the problem anyway

BTW, INT_RGB won't let you to have alpha channel in it. If it's needed, you should try some other image type, like INT_ARGB.
