Two instance of tomcat

Yes, you may need to run two separate instance of tomcat in same machine if you have limited memory in your system and you have to work on big applications.

It is very simple :-

1. Download tomcat 6.0 .

2. Install the first with default settings.

3. Start the instance and verify if it is installed and working.

4. Execute the installer again with custom settings

5. In the configuration options page change the ports mentioned to

 Server shutdown port 8006

Http connector  port 9090

AJP connector port 8008

and change the service name to :- tomcat62

6. In the installation path change the tomcat directory name to tomcat62.

7. Install and verify.

Hopefully both instance should work
