Tomcat instruction: translation from .bat to .sh

Question

I'm trying to setup SSL communcation for an application that uses a tomcat server. Unfortunately, the instructions are for the Windows version but the server I'm working on runs SUSE Linux. Here's the batch Script and here the shell script.

The instruction says to locate the line that contains ":execCmd". After that line, one has to insert

set CATALINA_OPTS="-Djavax.net.ssl.trustStore=foo.jks" "-Djavax.net.ssl.trustStorePassword=changeit"

I'm guessing the code to insert could be corrected by just leaving out the "set ".

As this appearst to overwrite the CATALINA_OPTS variable, my guess would be that putting this at the very first line might work.

However, before I mess up something or create an error that goes undetected later, I'd hope to get a second opinion here.

Answer 1

On Linux, the usual way to give tomcat additional options is via a setenv.sh file in the $CATALINA_HOME/bin directory (that's the same where catalina.sh is located). If such a file exists, it is automatically read during tomcat startup. And if you want to prevent your setenv.sh from overwriting existing settings, the best way is:

#!/bin/sh
JAVA_OPTS="$JAVA_OPTS -Djavax.net.ssl.trustStore=foo.jks" 
JAVA_OPTS="$JAVA_OPTS -Djavax.net.ssl.trustStorePassword=changeit"
