No server in windows>preferences

In Eclipse Kepler,

1. go to Help, select ‘Install New Software’
2. Choose “Kepler- http://download.eclipse.org/releases/kepler” site or add it in if it’s missing.
3. Expand “Web, XML, and Java EE Development” section Check JST Server Adapters and JST Server Adapters Extensions and install it

After Eclipse restart, go to Window / Preferences / Server / Runtime Environments

You did not install the correct Eclipse distribution. Try install the one labeled "Eclipse IDE for Java EE Developers".

I had the same issue. I was using eclipse platform and server was missing in my show view. To fix this go:

• help>install new software

• in work with : select : "Indigo Update Site - http://download.eclipse.org/releases/indigo/" , once selected, all available software will be displayed in the section under type filter text

• Expand “Web, XML, and Java EE Development” and select "JST Server adapters extensions"

• then click next and finish. The server should be displayed in show view
