Apache Camel Using Java DSL using Hello World

In this tutorial we will create a simple application to get started with Apache Camel using Java DSL.

This tutorial is explained in the below Youtube Video.

Lets Begin

The File component is present in the camel-core jar itself so no new dependency needs to be added.
We will create Eclipse maven project as follows-

Our pom file 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">


Next we create a class to construct a camel route. A Route is like an instruction definition to Camel on how to move your messages from one point to another. We are going to create SimpleRouteBuilder.java class that will move files from c://inputFolder to c://outputFolder.
Also here during the transfer from source folder we have written noop=true, this tells that the transferred file should remain in the source folder even after the transfer(copy paste). If this is not specified then after the transfer the file gets deleted from the source folder(cut paste).
If noop=true, Camel will set idempotent=true as well, to avoid consuming the same files over and over again.
package com.javainuse;

import org.apache.camel.builder.RouteBuilder;

public class SimpleRouteBuilder extends RouteBuilder {

    public void configure() throws Exception {


When Camel is started, it creates a CamelContext object that contains the definition of the Route to be started. Below we create default camel context and load the route created in SimpleRouteBuilder.
package com.javainuse;

import org.apache.camel.CamelContext;
import org.apache.camel.impl.DefaultCamelContext;

public class MainApp {

    public static void main(String[] args) {
        SimpleRouteBuilder routeBuilder = new SimpleRouteBuilder();
        CamelContext ctx = new DefaultCamelContext();
        try {
            Thread.sleep(5 * 60 * 1000);
        catch (Exception e) {


Run this MainApp.java. Any file in C:inputfolder will get copied to C://outputFolder.
Below we copy the employee-management-system.war to C:inputfolder.

Our camel application copies the file to C://outputFolder.
