The current version of Eclipse is Luna (4.4.0).
The WTP plugin that comes with
J2EE Eclipse doesn't retro-actively add new server versions, so
you should consider upgrading.
An alternative might be to install sysdeo/mongrel, which isn't bundled with specific versions of Eclipse and therefore isn't as tightly tied to a specific Eclipse release. Plus mongrel doesn't do bizarre things to Tomcat's insides like the WTP plugin does.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
