jetty+jersey servlet mapping not working

Question

i am trying to implement a REST web service using jetty and jersey. I created a maven webapp project and i also want to use the maven jetty plugin in this project.

The problem i am facing right now is that the servlet-mapping does not seem to work. I want the resource being mapped to http://localhost:8080/rest/test which i tried in the web.xml but when accessing the URI i get 404 not found.

Here is the pom.xml:

I did search for this problem in google but none of the solutions i found seem to work. And since this is my first time working with web servers and web services, i dont't entirely understand the whole topic yet.

Answer 1

Change @Path("/rest") to @Path("/test"), and get rid of the other @Path("/test") on the method. Every method not annotated with @Path, will go to /test on the class.

/rest/* is already define in the servlet mapping in the web.xml, so that will be be the root.

How you currently have it, you would need to access. /rest/rest/test
