I am using tomcat5.5 for a long on ubuntu servers 8.10 and 9.10 and '/usr/share/tomcat/webapps/' is the path where I place my .war files and access them on the browser over network. On a sytem I've installed tomcat6 and I'm failing to find that where do I place my .war file of tomcat6's webapps. I checked deploying war under /var/lib/tomcat6/webapps/ and the war file is extracted and I think this should be the location but I could not access the page when I tried http://serverip:8080/myapp. I could access the default page properly when I navigate to http://serverip:8080. The same war file is working fine on tomcat servers which were not installed from apt repository.
