GlassFish 4.0 / Jersey 2.0 - NoClassDefFoundError for JsonStructureBodyReader

由 旧街凉风 提交于 2019-12-05 23:11:46

If you're not using JSON (JSON Processing library) then you should remove jersey-media-json-processing module from the classpath of your client (which seems to be outside of GF). This module depends on jsonp-jaxrs.jar (+ javax.json.jar, javax.json-api.jar) which contains the JsonStructureBodyReader. The thing is that everytime the jersey-media-json-processing module is on a classpath Jersey tries to register JSON Processing providers via Auto-Discoverable mechanism. This means that in case of missing dependencies one would encounter an exteption similar to yours.

Just remove the glassfish library from build path in eclipse. Then do add external jars, and add all the jars from the following folders in glassfish4 directory.

  1. C:\glassfish4\glassfish\modules
  2. C:\glassfish4\glassfish\modules\endorsed
  3. C:\glassfish4\mq\lib

Here's the client code I used to write REST client using JAX RS

import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.core.MediaType;


public class test {

    public static void main(String[] args) {

        Client client = ClientBuilder.newClient();
        String name = client.target("http://localhost:9999/MyResourceRestfulService/myresources/myresource")
          .request(MediaType.TEXT_PLAIN)
          .get(String.class);

        System.out.println(name);
    }

}

If you are using Glassfish 4.x as server and its libraries. You have to add javax.son.jar jsonp-jaxrs.jar

Both libraries are located in \glassfish\modules

If you are using a JUNIT test with MAVEN just add

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>jsonp-jaxrs</artifactId>
    <version>1.0</version>
    <scope>test</scope>
</dependency>

to your pom.xml
