I want to define a new server (Tomcat 7.0) in Eclipse but unfortunately, I couldn’t proceed with the steps to create the server as both the ‘Next’ and ‘Finish’ button is grayed out and the server name is blank.
As for my situation, the runtime environment was a bit messed up between the Tomcat version which I downloaded from the Apache website and the downloaded version via Ubuntu apt-get method. I had removed the version which was downloded via apt-get method but I forgotten to fix the runtime environment. In order to solve the problem, I need to access to Window -> Preferences -> Server -> Runtime Environments to fix the broken link for the server by removing the old one and update it with the new one which was downloaded from the Apache website itself.
If that is not the case for you, you can give it a try with the steps mentioned on this page: Eclipse 3.7 (Indigo) + Tomcat7 — Cannot create a server using the selected type
