      Hi,

       

      I have JBOSS EAP 6.1.0 GA server on which i am deploying my ear application which contains the jar and war. I am using Jersey 2.5.1 implementation for my restful webservice clases

       

      The war file contains below class:

      @Path("test/{targetName}/{name}")
public class Test{
    
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Response getNextBatch (@PathParam("targetName") String targetName, @PathParam("name") String name) {
        JSONObject test = new JSONObject();
        try {
            test.put("targetName", "testing");
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return Response.status(200).entity(test).build();      
    }
        
}

       

      My lib directory has below jar files:

      jersey-common.jar
jersey-container-servlet.jar
jersey-container-servlet-core.jar
javax.ws.rs-api-2.0.jar
jersey-server.jar

       

      As I have read on https://jersey.java.net/documentation/latest/deployment.html under section 4.7.2. Servlet 3.x Container about deployment without application subclass using web.xml file, my web.xml file looks like:

      <web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee;http://java.sun.com/xml/ns/j2ee/web-app_3_0.xsd" version="3.0">
  <display-name>JerseyTest</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
<!-- jersey related mapping -->
  <servlet>
        <servlet-name>javax.ws.rs.core.Application</servlet-name>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>javax.ws.rs.core.Application</servlet-name>
        <url-pattern>/resources/*</url-pattern>
    </servlet-mapping>
  <servlet>

    <servlet-name>testServlet</servlet-name>
    <servlet-class>com.xxx.servlet.testServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>testServlet</servlet-name>
    <url-pattern>/testServlet</url-pattern>
  </servlet-mapping>

       

      I have commented the jaxrs mapping lines in domain.xml file to avoid conflict with RESTEasy.

       

      When I am deploying my ear file, i am getting below exception:
