Re: [jetty-users] ClassCast on parsing virtualHosts
Forget about my previous message. I read the sources a little bit further.
Seems like the Node class is an enumeration of Objects which are supposed to be Node instances again but apparently aren't. So the question for me is who put the strings there.
I am curious whether this can be (at first sight magically) solved by using the correct DTD as Jan suggested. Could you please report back? Thanks.

Betreff: Re[2]: [jetty-users] ClassCast on parsing virtualHosts

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

<Array type="java.lang.String">
...
</Array>
To fix the issue, first thing I would try is to omit the 'type' attribute, so it reads: 

<Array>
  <Item>example.com</Item>
</Array>
From my understanding (which is close to nothing) Jetty XML then would not try to parse the Array Items to a string but use the bare generic org.eclipse.jetty.xml.XmlParser$Node class.
From my quick look at the sources, it could also be a 'special border case'. To verify, could you just try inserting another item? Like so 

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath">/</Set>
  <Set name="war">/opt/nexus-2.6.3.war</Set>
  <Set name="virtualHosts">
     <Array type="java.lang.String">
       <Item>example.com</Item>
       <Item>example.org</Item>
     </Array>
  </Set>
</Configure>

Hope this helps.

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

 I'm trying to setup a virtual hosts on my jetty 9 based on these
 instructions:
http://www.eclipse.org/jetty/documentation/current/configuring-virtual-hosts.html 

 this is my webapp.xml:

 <Configure class="org.eclipse.jetty.webapp.WebAppContext">
     <Set name="contextPath">/</Set>
     <Set name="war">/opt/nexus-2.6.3.war</Set>
     <Set name="virtualHosts">
         <Array type="java.lang.String">
             <Item>example.com</Item>
         </Array>
     </Set>
 </Configure>

 and it causes this error to appear in logs:
