Answer 1

I have to do the following to make it work with tomcat 7.0.69 and java 1.8, and jersey 2.22.2 Just sharing it if it comes to any use of any body.

1. Add the following dependency in your Pom file :

     
       org.glassfish.jersey.containers
       jersey-container-servlet-core
       2.22.2
     
   
     
       org.glassfish.jersey.core
       jersey-client
       2.22.2
     
   
     
       org.glassfish.jersey.media
       jersey-media-json-processing
       2.22.2
     
   
         org.glassfish.jersey.containers
         
         jersey-container-servlet
         2.22.2
       
   
       
         org.glassfish.jersey.media
         jersey-media-sse
         2.22.2
       
   

2. Needs to be servlet 3 so Heading of the web.xml should be like this : < ?xml version="1.0" encoding="UTF-8"? > < web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0" >

3. Jersey Servlet Container should be async-supported, so add it in the jersey servlet in the web.xml :

< async-supported>true< /async-supported >

5. If you use any filter make sure it also async-supported :

   < async-supported>true< /async-supported>
