The jar files for OpenBase and PostgreSQL were listed by the shell script because those databases were installed on my system -- they are not necessary for CFMX, so that is not the problem.
About halfway down the shell script output, you scould see lines similar to:
This indicates that the JRun server is listening on port 8500 of the current host, and that CFMX has been made available for use.
12/07 01:12:01 info JRun Web Server listening on *:8500
12/07 01:12:01 info Deploying enterprise application "Macromedia ColdFusion MX" from: file:/opt/coldfusionmx/
12/07 01:12:02 info Deploying web application "ColdFusion Web Application" from: file:/opt/coldfusionmx/
Once the shell script has finished executing, you will get an output line something like:
Server default ready (startup time: 11 seconds)
You then need to access CFMX with the URL:
I have seen the 500 error message occur when you try to access the above URL and the JRun server is listening, but CFMX hasn't finished deploying (the shell script has not finished startup).
If you wait until you get the "Server default ready" message, then retry the URL, you should be OK.
If none of this works, contact me offline or post the output of your startup shell script.
