I've checked similar questions but all of them was solved by changing Jersey version, but looks like I'm using correct one.

List of libraries generated by maven:

Any ideas what I'm doing wrong?

You can face this exception if you are setting up jersey 2 project first time in eclipse using maven plugin. Message is simple enough to identify the root cause the Jersey libraries are not in classpath.

Solution – Add Jersey Library in Deployment Assembly

  • Open your project’s deployment assembly configuration.

  • Add Build path jar files in assembly so that they can be added to lib folder in final war file.

  • Deployment Assembly - Add Build Path Entries

  • Select Maven Dependencies

Now when you again run the project after building it, this will run fine and will be able to find org.glassfish.jersey.servlet.ServletContainer class.

Ok, found what was wrong. In my case I've added lib folder to WEB-INF (Project Structure->Artifacts, then in "Available Elements" select all of them, right click and select "Put into /WEB-INF/lib").
