Class JndiRepositoryFactory

java.lang.Object
  org.modeshape.jcr.JndiRepositoryFactory

All Implemented Interfaces:

ObjectFactory

public class JndiRepositoryFactory
extends Object
implements ObjectFactory

The JndiRepositoryFactory class provides a means of initializing and accessing repositories in a JNDI tree.

Example JNDI Configurations

Tomcat 5.5

The following configuration can be added to added to server.xml in Tomcat 5.5 to initialize a JcrRepository and add it to the JNDI tree.

   <GlobalNamingResources>
         <!-- Other configuration omitted -->
      <Resource name="jcr/local" auth="Container"
           type="javax.jcr.Repository"
           factory="org.modeshape.jcr.JndiRepositoryFactory"
           configFile="/tck/default/configRepository.xml"
           repositoryName="Test Repository Source"
           />
   </GlobalNamingResources>
 

This will create a repository loaded from the resource "/tck/default/configRepository.xml" (which must be accessible through the classpath) and return the JCR repository named "Test Repository Source". The name of the repository is important as a single configuration file may contain configuration information for many JCR repositories.

                                       NamingException

Creates an JcrRepository using the reference information specified.

This method first attempts to convert the obj parameter into a reference to JNDI configuration information. If that is successful, a JcrEngine will be created (if not previously created by a call to this method) and it will be configured from the resource at the location specified by the configFile key in the reference. After the configuration is successful, the JcrEngine will be queried for the repository with the name specified by the value of the @{code repositoryName} key in the reference.

Specified by:

getObjectInstance in interface ObjectFactory

Parameters:

obj - the reference to the JNDI configuration information; must be a non-null instance of Reference

name - ignored

nameCtx - ignored

environment - ignored

Returns:

the repository; never null

Throws:

IOException - if there is an error or problem reading the configuration resource at the supplied path

SAXException - if the contents of the configuration resource are not valid XML

NamingException - if there is an error registering the namespace listener

javax.jcr.RepositoryException - if the JcrEngine could not be started, the named repository does not exist in the given configuration resource, or the named repository could not be created
