Running JRun and ColdFusion with Java 1.4.2 on OS X

NOTE: The solution below is neither supported nor endorsed by Macromedia. Use at your own risk!

Most of you running JRun/CF on OS X are aware of the fact that we have been stuck with Java 1.3.1 while everyone else has gotten the benefit of newer versions of Java. For reasons unknown (at least to me), editing your jvm.config file and changing java.home to point to a newer version of Java did not work. Fortunately, there is another way. CD into JRun’s lib directory, and type the following command:

java -jar ./jrun.jar -start default

I have the process scripted. Below is the meat of my “start.sh” script:


#!/bin/bash

JRUN_HOME="/home/cantrell/Unix/JRun4"
LOG_HOME="${JRUN_HOME}/logs"
java -jar ${JRUN_HOME}/lib/jrun.jar -start default admin \
1>$LOG_HOME/default-out.log 2>$LOG_HOME/default-err.log

Unfortunately I have found that I have to start the admin server along with the default server in order to affect the JVM’s classpath (I need to add drivers for PostgreSQL). For some reason, using the -cp flag hasn’t worked. Still looking into that.

Anyway, once again, this is not a supported configuration, and if you choose to try it, you are doing so at your own risk.

  1. Thanx for posting this!!!If you add:cd ${JRUN_HOME}/libyou can invoke the script from anywhere. I also added an ampersand to the end of the java invocation line to run it in the background.

    Thanks, working nicely. I noticed that after running your script ps -ax | grep jrun gives:… /Applications/JRun4/bin/jrun -nohup -start -childVM cfusion… other server instances similarI run multiple servers (admin, cf, others) and found that I could start and stop individual servers using these flags, not sure if that helps work out a more robust start/stop script.

  3. JRun and Coldfusion Troubles

    I have had Coldfusion installed on my PC for a while but its not my main developing computer, so I tried to get Coldfusion onto my Mac. But there is no Mac version of Coldfusion, its just a Java version.
