Minor Description
Out-of-the box, Tomcat7.sh script runs on default JVM, which is for 32-bit Sun Java equal to 'Client' JVM.
I assume that starting tomcat on 'Server' JVM is generally better then 'Client' JVM.
Adding '$JSVC_JVM' into run, start and version actions of that script, would allow user to add e.g. "export JSVC_JVM='-jvm server'" into setenv.sh to use appropriate JVM, without need to modify the example script.
