I added the headless flag to catalina.sh as follows:
# ----- Execute The Requested Command -----------------------------------------
echo "Using CATALINA_BASE: $CATALINA_BASE" echo "Using CATALINA_HOME: $CATALINA_HOME" echo "Using CATALINA_TMPDIR: $CATALINA_TMPDIR" echo "Using JAVA_HOME: $JAVA_HOME"
if [ "$1" = "jpda" ] ; then
if [ -z "$JPDA_ADDRESS" ]; then
JPDA_ADDRESS="8000"
fi
if [ -z "$JDPA_OPTS" ]; then
JPDA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=$JPDA_ADDRESS,server=y,suspend=n"
fi
CATALINA_OPTS="$CATALINA_OPTS $JPDA_OPTS"
shift
fi
CATALINA_OPTS="-Djava.awt.headless=true"
This worked fine.

May I ask, how you did this ? I've also encountered
JNI_OnLoad errors runing on Solaris due, I suspect, the lack of
XWindows on my server. I tried adding the headless flag to
my catalina.sh script as follows ~
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 \
>> "$CATALINA_BASE"/logs/catalina.out 2>&1 &
else
"$_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 &
fi
But that just resulted in the following error,
java.awt.HeadlessException
at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:121)
at java.awt.Window.(Window.java:266)
at java.awt.Frame.(Frame.java:398)
at java.awt.Frame.(Frame.java:363)
at ImageUtils.loadImage(Unknown Source)
where the loadImage() function is simply supposed to load an image, public static Image loadImage(String fileName) { Image image = Toolkit.getDefaultToolkit().getImage(fileName); MediaTracker mediaTracker = new MediaTracker(new Frame()); mediaTracker.addImage(image, 0); try { mediaTracker.waitForID(0); } catch (InterruptedException ie) { // } return image; } Any ideas/help would be great. Stephen. ps. I also tried PJA but couldn't get that to work either :(
