Cannot add a project to a Tomcat server in Eclipse

Question

I cannot add my project to a server in Eclipse - why is that  I installed all necessary tools  Web Dev  Java EE  Server Adapters  and Tomcat itself  everything  I configured the runtime environments  adjusted all Java Versions to JDK 6  because it should run on Tomcat 6   but still the left side of the dialogue where I could add resources is empty when creating a new server  What else could I try  PS  I am using Eclipse v4 2  Juno  on Windows  7 Professional

Go to project properties - gt  Project Facets  Make sure the Dynamic Web Module and Java is checked  Apart from it   quot Cloud Foundry Standalone Application quot  needs to be un-checked  if it is already selected  By default  few IDEs preselect this option

Steps I used to resolve it   Double click on Tomcat Server in the Servers tab  In a dropdown next to Runtime Environment   select Apache Tomcat your version Click on save   Now  you should be able to add to server on right click  quot Add and Remove quot   Note  Additionally  when on clear run  you get an error for multiple instances  open server xml and ensure that it contains a single instance of each application and not multiple

You didn t create your project as  quot Dynamic Web Project quot   so Eclipse doesn t recognize it like a web project  Create a new  quot Dynamic Web Project quot  or go to Properties   Projects Facets and check Dynamic Web Module
