Could you share more details?
What application you migrate, does it work with 7.1.0?
How do you start the server? If the start fails I suppose you see errors or warnings in the server.log.
I am migrating a Java application which uses liferay portal framework, struts 1.2, hibernate 3, EJB 2.1. Initially we had some Jboss issues which I resolved. Basically my doubt is if I use JBoss 7.1.1 as standalone or with single instance inside Eclipse it works perfectly. But when I add as a new server which already working fine with JBoss 7.1.0 it is not starting and I don't really find any error logs. I doubt if I am missing some configuration changes to be done from Server window.
Please refer to the screen shot.
1.Added new server, named it as JBoss 7.1.1 Runtime, configured to point physical path
2.Modified configuration file standalone-full.xml under JBoss 7.1.1, included necessary modules.
3.Modified build path inside each of the EJB project to use JBoss 7.1.1 libraries
4.Clean built the project and started the server(right click and start) after making sure deployments having the .dodeploy marker file
There were no errors during build or deployment
Note: When I switch to JBoss 7.1.0 back it works fine and starts successfully both the server and application as well.
