Additional to Message 91060:

Yes, I have inserted a blank line.

Here is the source code of the DTML Method (SimpleExample.jnlp):

Content-Type: application/x-java-jnlp-file

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

<jnlp

codebase=http://localhost/
href="SimpleExample.jnlp">
    <information>
       <title>Swing Application - Hello World</title>
       <vendor>Rags</vendor>
       <description>Swing Application - Hello World</description>
       <description kind="short">Swing Application - Hello World</description>
       <offline-allowed/>
     </information>
     <resources>
       <j2se version="1.3"/>
       <jar href="SimpleExample.jar"/>
     </resources>
     <application-desc main-class="SimpleExample"/>
</jnlp>

The SimpleExample.html links to SimpleExample.jnlp and the third file in the Zope

folder is SimpleExample.jar.

Java Web Start is loaded correctly and than I get a download error when it tries to

access the recource "http://localhost/SimpleExample.jnlp", the server returns wrong MIME type text/html.
