Seem that you register a resourse with server scope but you lookup with
application scope. 
Or you do a lookup of jms/connectionFactory
or in the jetty-env.xml register jndi.Resource with argument0 webappcontext
reference. 

<Configure id='wac' class="org.eclipse.jetty.webapp.WebAppContext">
... 
        <New class="org.eclipse.jetty.plus.jndi.Resource">
                <Arg><Ref
id='wac' /></Arg> 
                <Arg>jms/FS_CF</Arg>
                <Arg>
                    
   <New class="org.apache.activemq.ActiveMQXAConnectionFactory">
                    
           <Arg>vm://BROKER?broker.persistent=false</Arg>
                    
   </New> 
                </Arg>
        </New> 
... 

new InitialContext().lookup("java:/comp/env/jms/FS_CF");

Subject	[jetty-users] javax.naming.NamingException: This context is immutable; remaining name 'env'

Hello,

I was just able to make JNDI work on my project. I am using jetty 
7.1.4.v20100610.

On JETTY_HOME/etc/jetty.xml, I added an ActiveMQConnectionFactory that
will be looked up from the code:

   <New id="cf" class="org.eclipse.jetty.plus.jndi.Resource">
     <Arg><Ref id="Server"/></Arg>
     <Arg>jms/connectionFactory</Arg>
     <Arg>
       <New class="org.apache.activemq.ActiveMQConnectionFactory">
         <Arg>tcp://localhost:61616</Arg>
       </New>
     </Arg>
   </New>

and looked up as

       InitialContext context = null;
       ConnectionFactory connectionFactory = null;
       try {
           context = new InitialContext();
           connectionFactory = 
(ConnectionFactory)context.lookup("java:comp/env/jms/connectionFactory");
       } catch (NamingException e) {
           logger.error("initConnection",
e);
       }

This is actually working on every jetty server restart.

Problem starts when I do a redeploy of the WAR app that does the looking
up for ActiveMQConnectionFactory. I use cargo for redeployment. Cargo 
successfully redeploys the WAR file but right after the deployment, I 
get this from jetty's log:

javax.naming.NamingException: This context is immutable; remaining name
'env'
   at 
org.eclipse.jetty.jndi.NamingContext.createSubcontext(NamingContext.java:432)

   at 
org.codehaus.cargo.deployer.jetty.DeployerServlet.doPut(DeployerServlet.java:192)

At first I thought that this was just being caused by hot deployment and
redeploy raise condition, but it was not. The deployed app is not 
working not until I do a manual jetty server restart which after that,
everything works fine again.

Any ideas?

Thanks in advance.
