I'm using Jboss 4.2, which uses JbossWeb to deploy web applications.

Anyway, there are some similar thing between Tomcat and JbossWeb and I tried 
the way you suggested me, but I'm getting a naming not bound exception on jcr. 
The webapp I'm trying to modify is written with SEAM and the component who 
initializes the repository is set with @Startup.

It seems strange that lots of people have no difficulties with it, maybe I'm 
missing something but I really don’t know what.

Subject: Re: accessing JCR over JNDI

Well, first question is: how do you start JCR?  You need model 2 to be able to 
access JCR from all deployed apps.
To do so you msut define global JNDI resource  in tomcat's config like this:
  <GlobalNamingResources>
   ......
    <!--
       JackRabbit content repository //
     -->
    <Resource configFilePath="/usr/local/jackrabbit-repo/repository.xml"
              
factory="org.apache.jackrabbit.core.jndi.BindableRepositoryFactory"
              name="jcr/globalRepository" 
repHomeDir="/usr/local/jackrabbit-repo"
              type="javax.jcr.Repository"
              auth="Container" />

  </GlobalNamingResources>

Thus Tomcat must have all libraries of JCR available. The simpliest way  is  
just to put all of it in ${tomcat_home}/lib

So tomcat will start JCR whet it starts.
Next step is configuration of web application. You must put following reference 
to global repo into your context.xml

 <ResourceLink global="jcr/globalRepository" name="jcr/repository" 
type="javax.jcr.Repository"/>

After that ytou can obtain JNDI access to JCR with following code:

        BindableRepository jrepository = null;

        try {
            InitialContext context = new InitialContext();
            Context environment = (Context) context.lookup("java:comp/env");
            jrepository = (BindableRepository) 
environment.lookup("/jcr/repository");

...}
 the best place for this code is
 public void contextInitialized(ServletContextEvent sce) method  of application 
listener. Then you can bind repository to web application context and use in 
any place of your
application.
