I just install Tomcat version 7.0.37 to replace the old 7 version, but the new server could not be add to Eclipse with error message "Cannot create a server using the selected type".
To solve the problem, I've remove these files: org.eclipse.jst.server.tomcat.core.prefs and org.eclipse.wst.server.core.prefs from /workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings
and delete the old server.
After restarting Eclipse, "Define a New Server", now Tomcat works.
