Re: [jetty-users] ClassCast on parsing virtualHosts
as.maps, 
Nope, it's a DTD issue, like Jan pointed out.
Either a lack of DTD or the wrong DTD is the root cause.
Fix that and it will work.

Feel free to experiment in the jetty-distribution.
Edit the demo-base/webapps/test.xml
Enable the virtualHosts section (which is commented out)
Run the demo base.
   [demo-base]$ java -jar ../start.jar
It works.
Now remove the DTD line and try again
   [demo-base]$ java -jar ../start.jar

While I am not an expert on this topic, I guess the problem arises from

To fix the issue, first thing I would try is to omit the 'type' attribute, so it reads:

<Array>
  <Item>example.com</Item>
</Array>

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

  <Set name="virtualHosts">
     <Array type="java.lang.String">

</Configure>

Hope this helps.

Betreff: Re: [jetty-users] ClassCast on parsing virtualHosts

Rafal,

Check your 2nd line of the xml config file is the right version for
jetty-9.x. It should be:

<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN"
"http://www.eclipse.org/jetty/configure_9_0.dtd">

 Hi
