Jax-rs -jersey Cross Origin request enablement

I am trying to make my very first jersey rest api, using version 2.X but i have a problem about CORS.

Before configuration files, this is my curl output:

 curl -i http://localhost:8080/camp/rest/user/register
 HTTP/1.1 200 OK
 Server: Apache-Coyote/1.1
 Content-Type: application/json
 Content-Length: 32
 Date: Sat, 07 Feb 2015 15:34:28 GMT

From browser i can get right output, there is no problem about it. But i couldnt enabled cors with my tomcat server.

Here is my web.xml

         <?xml version="1.0" encoding="UTF-8"?>
         <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">
        <display-name>camp</display-name>
         <servlet>
         <servlet-name>camp</servlet-name>
        <servlet-class>
                 org.glassfish.jersey.servlet.ServletContainer
        </servlet-class>

        <init-param>
            <param-name>jersey.config.server.provider.packages</param-name>
            <param-value>com.yigit.camp.api.out</param-value>
        </init-param>

        <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.yigit.camp.api.security</param-value>
        </init-param>

        <init-param>
            <param-name>org.glassfish.jersey.container.ContainerResponseFilters</param-name>
            <param-value>com.yigit.camp.api.security.CORSResponseFilter</param-value>
        </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>camp</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

<filter>
  <filter-name>CorsFilter</filter-name>
  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>

  <init-param>
      <param-name>cors.allowed.origins</param-name>
      <param-value>*</param-value>
  </init-param>
  <init-param>
      <param-name>cors.allowed.methods</param-name>
      <param-value>GET,POST,HEAD,OPTIONS,PUT</param-value>
  </init-param>
  <init-param>
      <param-name>cors.allowed.headers</param-name>
      <param-value>Content-Type,X-Requested-With,accept,Origin,Access-Control-Request-Method,Access-Control-Request-Headers</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>CorsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>

And here is my Filter class:

package com.yigit.camp.api.security;
import javax.ws.rs.ext.Provider;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerResponseContext;
import javax.ws.rs.container.ContainerResponseFilter;

@Provider
public class CORSResponseFilter implements ContainerResponseFilter {

@Override
public void filter(ContainerRequestContext creq, ContainerResponseContext cres) {
    cres.getHeaders().add("Access-Control-Allow-Origin", "");
    cres.getHeaders().add("Access-Control-Allow-Headers", "");
    cres.getHeaders().add("Access-Control-Allow-Credentials", "");
    cres.getHeaders().add("Access-Control-Allow-Methods", "");
    cres.getHeaders().add("Access-Control-Max-Age", "");
}

}

I did same configuration on tomcats web.xml too, but result is the same.

What is the right way to solve this problem?

Regards guys

This solution is for tomcat server

Add following code to your web.xml and add following two jars to your build path * coarse-filter-1.7.jar * java-property-utils-1.7.1.jar

add this web.xml

 <filter>
    <filter-name>CORS</filter-name>
        <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
    <init-param>
     <param-name>cors.allowOrigin</param-name>
        <param-value>*</param-value>
    </init-param>
    <init-param>
     <param-name>cors.supportedMethods</param-name>
        <param-value>GET, POST, HEAD, PUT, DELETE</param-value>
    </init-param>
    <init-param>
    <param-name>cors.supportedHeaders</param-name>
    <param-value>Accept, Origin, X-Requested-With, Content-Type, Last-      Modified</param-value>
    </init-param>
    <init-param>
        <param-name>cors.exposedHeaders</param-name>
        <param-value>Set-Cookie</param-value>
    </init-param>
    <init-param>
        <param-name>cors.supportsCredentials</param-name>
        <param-value>true</param-value>
    </init-param>
    </filter>

    <filter-mapping>
    <filter-name>CORS</filter-name>
    <url-pattern>/*</url-pattern>
    </filter-mapping>

Add this in your web.xml:

<init-param>
    <param-name>javax.ws.rs.Application</param-name>
    <param-value>com.yigit.camp.api.MyAppConfig</param-value>
</init-param>

Then add this class:

package com.yigit.camp.api;
public class MyAppConfig extends Application {
    @Override
    public Set<Class<?>> getClasses() {
        final Set<Class<?>> classes = new HashSet<Class<?>>();        
        classes.add(CORSResponseFilter.class);        
        return classes;
    }
}

Now your response filter should be used.
