Trouble publishing a RSS feed

[oggmeister]

Hello,

I'm trying to publish a RSS feed. Therefore I've written the following rss.xml file:

<?xml version="1.0" encoding="utf-8" ?>
<rss version="0.91" xmlns:ui="http://java.sun.com/jsf/facelets">
     <channel>
          <title>Hixmen</title>
          <link>http://localhost:8080/hixmen</link>
          <description>Die letzten 10 offiziellen Foreneinträge</description>
          <language>de-de</language>
          
          <ui:repeat value="#{rssFeed.entries}" var="topic">
          <item>
               <title>#{topic.title}</title>
               <link>http://localhost:8080/hixmen/forum/viewTopic.seam?topicId=#{topic.id}</link>
          </item>
          </ui:repeat>

     </channel>
</rss>

When I request that file through my browser (Firefox) by calling http://localhost:8080/hixmen/forum/rss.seam, Firefox allows me to subscribe to the feed. But when I try to access it afterwards, it says that it cannot load the feed (invalid URL). The generated response seams to be sound, though:

<?xml version="1.0" encoding="utf-8" ?>
<rss version="0.91">
     <channel>
          <title>Hixmen</title>
          <link>http://localhost:8080/hixmen</link>
          <description>Die letzten 10 offiziellen Foreneintr&auml;ge</description>
          <language>de-de</language>

</rss>

I guess this has something to do with the feed's URL pointing to rss.seam instead of rss.xml. But when I access http://localhost:8080/hixmen/forum/rss.xml, Seam does not intercept the request and the XML file is return as it is (including the ui:repeat control).

What can I do?

Thanks for any help!

Update:

I made Seam intercept the request for rss.xml by adding the following to the web.xml:

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xml</url-pattern>
</servlet-mapping>

So the feed's URL points to rss.xml now but the problem remains...

Solution:

I finally solved the problem. It was the HTML-Entities (ä, ö). Firefox did not know how to handle them, since there was so schema or dtd defined.

So I simply replaced the <?xml ... by <!DOCTYPE .... My code now looks looks this:

<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
                      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<rss version="0.91" xmlns:ui="http://java.sun.com/jsf/facelets">
     <channel>
          <title>Hixmen</title>
          <link>http://localhost:8080/hixmen</link>
          <description>Die letzten 10 offiziellen Foreneinträge</description>
          <language>de-de</language>
          
          <ui:repeat value="#{rssFeed.entries}" var="topic">
               <item>
                    <title>#{topic.title}</title>
                    <link>http://localhost:8080/hixmen/forum/viewTopic.seam?topicId=#{topic.id}</link>
               </item>
          </ui:repeat>

     </channel>
</rss>

Et voilà! Everything works fine.

Man was that a struggle ...
