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.
