Apache Camel + Rest Webservice using JAX-RS Hello World Example

In this post we will expose a REST Webservice using Apache Camel and JAX-RS. Java API for RESTful Web Services (JAX-RS) is a Java programming language API spec that provides support in creating web services according to the Representational State Transfer (REST) architectural pattern.
Using JAX-RS we can configure the server to expose a REST serverice which returns an output by directly calling the specified resource class. If we have to use the camel route for returning the response then we make use of CXF-RS. In the next post we implement REST using Apache Camel and CXFRS

This tutorial is explained in the below Youtube Video.

Lets Begin

The project structure we would be creating will be as follows-

The pom.xml will be as follows-
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">



Create the Resource class as follows-
package com.javainuse.beans;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;

public class EmployeeServiceResource {

	public EmployeeServiceResource() {

	public String getCustomer(@PathParam("name") String name) {
		return "Welcome " + name;


Next in the applicationContext.xml we configure the Rest Server using JAX-RS.
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:camel="http://camel.apache.org/schema/spring"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd      
        http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
        http://cxf.apache.org/transports/http/configuration http://cxf.apache.org/schemas/configuration/http-conf.xsd
        http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd
        http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">

	<jaxrs:server id="restService" address="http://localhost:9000/employeeservice">
			<ref bean="employeeService" />

	<bean id="employeeService" class="com.javainuse.beans.EmployeeServiceResource" />
Next we build the application and then deploy it in JBoss Fuse as follows-
Now that the bundle has started,if we go to http://localhost:8181/cxf we see that our REST service is shown as successfully deployed. We can also get the WADL URL from here.
Since its a simple GET request we will use the browser to test it. In the browser go to the url.
