I am planning to using Apache Tomcat for my development purpose in Eclipse IDE. I have created a webservice application, for this I need to configure Installed runtime as Tomcat Server, to run the service.
When I try to install it, I find it was missing in the list of servers.

How can I resolve this?
Window > Show View > Servers. From there,Right click > New > Serverand you should see a first group calledApache, with plenty of Tomcats to choose from.It might depend on the version of Eclipse you are using. I know for sure that Eclipse for Java EE Developers contains these servers, Eclipse Classic or Eclipse for Java Developers might not include them.
