Building a simple AtomPub client with Netbeans 7, Maven, Java and Apache Abdera

Post to Twitter

In my last article I showed you how to create and run a simple AtomPub server using Apache Abdera. Today we will create a client (using modified code provided in this guide as well as the Apache Abdera examples) to put some data into the AtomPub server.

Updated Oct. 31, 2011: Code updated to return the actual status upon creation of a new ATOM entry

At this point I assume you already have Java and Netbeans 7 running, if not you can go here to get them both. I also assume you have some Netbeans and Java knowledge.

Start Netbeans 7 and create a new Maven Java project named: ATOMPubClient

Right-click on the Dependencies and select: Add Dependency… When the dialog opens up put in the Query textbox the following: abdera-client

In the class (already created) modify it so the code looks like this:

 * Original code created by the Apache Abdera team
package com.giantflyingsaucer.atompubclient;

import java.util.Date;

import org.apache.abdera.Abdera;
import org.apache.abdera.factory.Factory;
import org.apache.abdera.model.Entry;
import org.apache.abdera.protocol.client.AbderaClient;
import org.apache.abdera.protocol.client.ClientResponse;
import org.apache.abdera.protocol.client.RequestOptions;

public class App {

    public static void main(String[] args) throws Exception {
        Abdera abdera = new Abdera();
        AbderaClient abderaClient = new AbderaClient(abdera);
        Factory factory = abdera.getFactory();
        Entry entry = factory.newEntry();
        entry.setTitle("This is the title");
        entry.setUpdated(new Date());
        entry.setContent("Hello World");
        report("The Entry to Post", entry.toString());

        RequestOptions opts = new RequestOptions();

        ClientResponse resp ="http://localhost:9002/employee", entry, opts);
        report("HTTP STATUS CODE", resp.getStatusText());

    private static void report(String title, String message) {
        System.out.println("== " + title + " ==");
        if (message != null)


== The Entry to Post ==
<entry xmlns=""><id>,2011:foo</id><title type="text">This is the title</title><updated>2011-10-31T19:46:26.891Z</updated><author><name>Chad</name></author><content type="text">Hello World</content></entry>


This is very simple, an entry is created and the feed is returned – nothing more. I’ve ignored the capability of editing and deleting. This code can be improved in several ways but my purpose was just to make it a bit easier for developers to get started with Apache Abdera and to supplement the existing documents.

The full source code is available here.
