java update broke jedit 4.3.2 for me

Submitted by jeditcdnguy on Tuesday, 26 October, 2010 - 16:34

I'm running ubuntu jaunty when I got an update today re:java

After the update jedit 4.3.2 stopped working

Here's what happens when I run it in the terminal

terry@beauty:/usr/lib/jvm/java-6-sun-1.6.0.22/jre/bin$ java jedit
Exception in thread "main" java.lang.NoClassDefFoundError: jedit
Caused by: java.lang.ClassNotFoundException: jedit

Which command did You invoke

Which command did You invoke at the terminal?

Please invoke "which jedit", which tells You the path of the used shell script. What's the content of this script?

Got it!

You da man!

Which jedit returned this

/home/terry/bin/jedit

which when looked at with cat returned this

#!/bin/sh
#
# Runs jEdit - Programmer's Text Editor.
#

# Set jvm heap initial and maximum sizes (in megabytes).
JAVA_HEAP_MAX_SIZE=192

DEFAULT_JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.20/jre"
if [ -z "$JAVA_HOME" ]; then
JAVA_HOME="$DEFAULT_JAVA_HOME"
fi

# Launch application.

exec "$JAVA_HOME/bin/java" -Xmx${JAVA_HEAP_MAX_SIZE}M -jar "/home/terry/jedit/4.3.2/jedit.jar" "$@"

using gedit to turn

DEFAULT_JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.20/jre"

into the new

DEFAULT_JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.22/jre"

which fixed the problem!

Thanks!

other script

There should be a better script which looks for an existing java installation under usr/local/bin. If You found that You could delete the other one.
