java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer

Question

You may feel this is a duplicated question, but none of the questions with the same title solve my problems. I am using Jersey 2.0 creating a RESTful web service in Eclipse,

Answer 1

For me, the fix was doing this:

Right click on Project -> Properties -> Java Build Path -> Libraries ->
Add Library... -> Server Runtime -> Apache Tomcat v7.0 -> Finish

Another step i did was to import stuff in Maven but it wasnt neccessary as it is running fine without it too.

But here it is if it helps anyone

    
        javax.servlet
        servlet-api
        2.5
        provided
    
    
        javax.servlet.jsp
        jsp-api
        2.2.1-b03
        provided
    

putting servlet jars in WEB-INF/lib just did things more complicated as the Exception Message got more complicated and irrelevant

EDIT: oh what also does help is to do an Update Project on your Maven Project.
