To set the JBOSS_CLASSPATH Variable on Solaris and Linux Platforms:

1. In the JBOSS_HOME/bin/run.sh script, find the following lines:

   if [ "x$JBOSS_CLASSPATH" = "x" ]; then
    JBOSS_CLASSPATH="$JBOSS_BOOT_CLASSPATH:$JAVAC_JAR"
    else
    JBOSS_CLASSPATH="$JBOSS_CLASSPATH:$JBOSS_BOOT_CLASSPATH:$JAVAC_JAR"
   fi 

2. After the lines you found in Step 1, add the following new lines:

   CONFIG=$2
   if [ "x$1"="x" ] && [ "x$CONFIG" = "x" ]; then CONFIG=default; fi
   if [ -r "setAgentClasspath$CONFIG.sh" ]; then
            ./opt/jboss-4.0.2/bin/setAgentClasspath$CONFIG.sh 
   fi

   Note: The previous command is for JBoss server 4.0.2. If you are using a different version, specify the appropriate JBoss server directory.

3. Save your changes.
