Is it possible to create another directory/port like 8081 to copy over all the java code, setup JDK and install tomcat 5.x in it?
All I want to see/test existing code on newwer version of tomcat.
Can someone please advise if this possible?
I looked around and i found tomcat can be started using server.xml file with -f option so I can have two tomcats running on two different ports 8080 (existing) and 8081 (newer version) , recompile all java code and test out.
You can run as many instances of Tomcat as you like. As you've mentioned, the port settings can be configured in conf/server.xml.
Besides changing the HTTP port (8080), you will also need to change the SHUTDOWN port. By default it is set to 8005. It doesn't matter what you change it to as long as you use a value that is already being used on your system.
