RE: Multiple Instances on one Machine
I have a related issue. (should the be a separate thread?) I had two instances of Tomcat5.5 on a windows XP Pro Workstation. And I had a batch file I got off the web to launch the second instance using a shared CATALINA_HOME but each with a different CATALINA_BASE When I upgraded to Tomcat6 it broke the startup. I tried to modify it by changing paths and the like but it failed. Anyone have an updated method for doing this?

It won't do exactly what you are trying to do, but try reading the RUNNING.txt that came with your Tomcat package. There's a section in there regarding advanced configuration where you use a single install and multiple base directories where completely separate configurations live. So, it's slightly more complicated than just having more than one server.xml file in your conf directory, but not by much. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFF8BqA9CaO5/Lv0PARAqXIAKCB+0Yb2CEqIB+Rh47+kO7ejfBHQwCgo8VE zKjICZHrXRZ1RqqD3rSuacU= =sW6t -END PGP SIGNATURE- - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

From: Rahul [mailto:[EMAIL PROTECTED] Subject: Multiple Instances on one Machine I have two webapps a and b with their respective web.xml files in $CATALINA_HOME\webapps\WEB-INF.

Do the Host elements in each of your server-*.xml files declare the same appBase? If so, you're going to get both apps deployed in both Tomcat instances.

Re: Multiple Instances on one Machine
Thanks Chris and Chuck. I have created separate bases (e.g. aBase) and within it I have webapps\a and so on respectively. It works fine now. One question: I don't have the Context spec file like aBase\conf\catalina\localhost\a.xml etc, but it doesn't seem to be affecting anything. What's the significance of that? - Rahul. PS: This was a typo in original message $CATALINA_HOME\webapps\WEB-INF, should have been $CATALINA_HOME\webapps\a or b\WEB-INF - Original Message From: Caldarale, Charles R [EMAIL PROTECTED] To: Tomcat Users List users@tomcat.apache.org Sent: Thursday, March 8, 2007 6:55:06 AM Subject: RE: Multiple Instances on one Machine From: Rahul [mailto:[EMAIL PROTECTED] Subject: Multiple Instances on one Machine I have two webapps a and b with their respective web.xml files in $CATALINA_HOME\webapps\WEB-INF.

What's the significance of that? You don't actually need a Context element for a webapp unless you can't deploy under appBase or have to change the default attributes. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
