[SOLVED] Can not receive Data from RSS Feed in Java Spring

I want to receive Data from a RSS Feed in Java Spring with this code:

package org.springframework.integration.samples.feed;

import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.messaging.Message;
import org.springframework.messaging.PollableChannel;
import com.rometools.rome.feed.synd.SyndEntry;

public class Feed {

    public static void main(String[] args) {
        ConfigurableApplicationContext ac =
                new ClassPathXmlApplicationContext("META-INF/spring/integration/FeedInboundChannelAdapterSample-context.xml");
            PollableChannel feedChannel = ac.getBean("feedChannel", PollableChannel.class);
        for (int i = 0; i < 10; i++) {
            Message<SyndEntry> message = (Message<SyndEntry>) feedChannel.receive(1000);
            if (message != null){
                SyndEntry entry = message.getPayload();
                System.out.println(entry.getTitle());
            }
            else {
                break;
            }
        }
        ac.close();
 }
}

FeedInboundChannelAdapterSample-context.xml:

<?xml version="1.0" encoding="UTF-8"?>

                    channel="feedChannel" 
                    auto-startup="true"
                    url="http://pharmacie.lu/flux_rss.xml">
    <int:poller fixed-rate="10000" max-messages-per-poll="100" />
</int-feed:inbound-channel-adapter>

<int:channel id="feedChannel">
    <int:queue/>
</int:channel>

The URL with the feed: http://pharmacie.lu/flux_rss.xml

The Problem is that I get a null message back and I dont know why:

When I use the url rss.cnn.com/rss/cnn_topstories.rss instead, the code works.

(The code is from an example of the Spring Integration RSS Feed Module at github: https://github.com/spring-projects/spring-integration-samples/tree/master/basic/feed)

My question is why the code above works with the url in the example but not with the url pharmacie.lu/flux_rss.xml?
