Hi Chris, Thank you for responding. Alternatives is defaulting to /usr/local/jdk1.6.0_20/bin/java (jdk from sun)
/usr/bin/java has a symlink to -> /usr/local/jdk1.6.0_20/bin/java We launch Tomcat by http://localhost:8080 We start it by running tomcat5 from /etc/init.d folder; This file calls /usr/bin/dtomcat, which sets some env variables. $CATALINA_HOME is /usr/share/tomcat5 version.sh file is not there in the /bin folder.
