I have Eclipse Juno with Spring Tools Suite plugin installed.
I need to deploy a newly imported web project to Tomcat 7, which I installed on my system via repository.
The problem is that the New Server Wizard screen won’t allow me to select Tomcat 7, as the description is empty and unmodifiable.

How can I fix this? I can select other versions of Tomcat but when I select the installation path of Tomcat I get an error that the installed version is 7.
