[Jetty-support] Deploying to running server problem

[Martin N. <mar...@gm...>]

Hello.
  What I am trying to do is to deploy to already running server. I did not
find any other way than to use ContextDeployer (if it exists, I will be
pleased to learn it). I tried to use minimal xml and put into the /contexts
folder:
<?xml version="1.0"  encoding="ISO-8859-1"?>
<Configure class="org.mortbay.jetty.webapp.WebAppContext">
  <Set name="contextPath">/zk2</Set>
  <Set name="war"><SystemProperty name="jetty.home"
default="."/>/webapps/zk.war</Set>
</Configure>

I have several questions:
1) Why is the contextPath needed in the xml that I put into /contexts
folder? It seems it is not used anyway. My jetty-web.xml in zk.war looks
like:
<?xml version="1.0" encoding="UTF-8"?>
<Configure class="org.mortbay.jetty.webapp.WebAppContext">
  <Set name="contextPath">/zk</Set>
</Configure>
Now I have 2 instances running (at least two MBeans as observed through the
jconsole), but both on the same context path /zk taken from the war file.
Where is the contextPath from the zk.xml in /contexts folder?

2) Is it possible to destroy the preceding MBean and force the new MBean to
have id=0 instead of id=1, 2, ... when using the context deployment through
some xml file in /contexts folder?

3) In README.txt in /contexts folder there is "Frequenty the context
configuration files here will reference war files or directories from
$JETTY_HOME/webapps.  Care must be taken to avoid a WebAppDeployer deploying
duplicates of such webapplications." May I ask how must I take care to avoid
that? From what I've observed it seems that if the contextPath is the same
both  in jetty-web.xml in the war file and zk.xml in the /contexts folder,
it deploys only one instance, is that correct?

I hope I wrote it understandably :) Any help would be greatly appreciated.

With regards,
  Martin
