    Hello.
    I believe the error is not because of datasource.
    XmlReader is not able to find the file news.rss.
    In your source code the statement is,
    URL url = new URL("http://localhost:8080/publisher/news.rss");

    while in the exception it is,
    java.io.FileNotFoundException: http://localhost:8080/publisher/web/news.rss

    The two paths do not match.
    So can you check in your web application folder where is news.rss existing? In the publisher folder or in the publisher/web folder?
    I guess its probably in the publisher folder. If so just move it to the the sub-folder web and try executing.
    Let me know if the problem still exists.

    Syed.
