I am making first simple RESTFul API to my project and I am using Maven. Frist, I created the maven archetype jersey-quickstart-webapp with default API. I've added my files, added dependencies. However when I use API URL: localhost:8080/webapi/myresource -> I've got 500 error here it is:

HTTP Status 500 – Internal Server Error

Type Exception Report

Message Servlet.init() for servlet [Jersey Web Application] threw exception

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

Exception

I am using Netbeans and Tomcat. I thought the error is caused because of lack hk2-api dependency, but nothing changed when I've added it.

OK, I've found the solution. My bad! I copied by mistake libraries that I download manually before I started to use Maven. After I delete all those .jar files everything starts to work. Sorry, that's my bad, the question can be closed.
