JAX-RS @MatrixParam

In this tutorial we are going to see JAX-RS MatrixParam using  RESTful web service @MatrixParam annotation
MatrixParam is set of name value pair separated by semi colon, for example name = value;
1. Create new Dynamic web project by choosing File –> New –> Dynamic Web Project.
2. Create the Project called RESTful-WebService
3. Add the following jar into WEF-INF/lib folder
add jar
4. Create package called com.javatutorialscorner.jaxrs.matrixparam under RESTful-WebService
5. Create Java class MatrixParamService under com.javatutorialscorner.jaxrs.matrixparam package
package com.javatutorialscorner.jaxrs.matrixparam;

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

public class MatrixParamService {

public Response getTutorial(@PathParam("site") String site,
@MatrixParam("tutorial") String tutorial,
@MatrixParam("rank") String rank) {
return Response
.entity("Web Site : " + site + " Tutorial : " + tutorial
+ " Rank : " + rank).build();



6.Configure Jersey Servlet Dispatcher

you need to configure REST as servlet in web.xml.


<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">


The servlet class available in jersey com.sun.jersey.spi.container.servlet.ServletContainer. The init param com.sun.jersey.config.property.package is used to define in which package jersey will look for the service classes.This package points to your resource class package. URL pattern is the part of base URL

Now you can run the service and access the service by calling the following URL


you can call the service by using web browser or from client class.

Web browser call


Create Client

1.Create package called com.javatutorialscorner.jaxrs.client under RESTful-WebService project

2.Create Client Java Class RESTfulClient under  com.javatutorialscorner.jaxrs.client package

RESTfulClient .java

package com.javatutorialscorner.jaxrs.client;

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.client.config.ClientConfig;
import com.sun.jersey.api.client.config.DefaultClientConfig;

public class RESTfulClient {

* @param args
public static void main(String[] args) {
// TODO Auto-generated method stub
String baseURI = "http://localhost:8080/RESTful-WebService";
ClientConfig config = new DefaultClientConfig();
Client client = Client.create(config);
WebResource service = client.resource(baseURI);
System.out.println("output for Matrix param");
.path("tutorial/javatutorialscorner.com;tutorial=RESTful WebService;rank=1")



Now you can run the client and see the following output in console

output for Matrix param
