REST jersey json NoSuchFieldError: WADL and Illega

问题:

I'm trying to build a WebApplication with REST Web Services and successfully fought some troubles already. But i couldn't solve this one so far.

I'm using a TomCat v7.0 localhost and try to access a simple @GET Resource. But when i click on the Resource, the following Errors appear:

A MultiException has 2 exceptions.  They are:
1. java.lang.NoSuchFieldError: WADL
2. java.lang.IllegalStateException: Unable to perform operation: create on org.glassfish.jersey.server.wadl.processor.WadlModelProcessor

I was searching stackoverflow and found a question with a maybe identical problem, but no solution (asked in April 2016)

I started this project as Maven project in eclipse neon.

Here are some files:

simple REST Test class:

package data.controller;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;

@Path("/test")
public class RESTTest {

    @GET
    public Response getString() {
        return Response.status(200).entity("getString is called").build();
    }
}

and finally the stack trace:

type Exception report

my Libs: referenced libraries WEB-INF lib-folder

I think the problem might be caused by some libs, but I'm not sure and several changes didnt fix this problem.

I'm thankful for each answer. If i forgot something, feel free to ask. Thank you

回答1:

If you are using IntelliJ IDE, Search for WadlModelProcessor class, you will see which library has this class. In this case, it will be more than one library.

You need to exclude one of the library which is the culprit from your pom.

In my case, it was jaxrs-ri - 2.11 jar - I excluded this

回答2:

I think you have miss the @RequestMapping annotation

e.g.

@RequestMapping(value="/methodName", method=RequestMethod.GET)
    public Response getString() {
        return Response.status(200).entity("getString is called").build();
    }
