/**
* Servlet that makes a remote repository from JNDI available as an attribute
* in the servlet context.
*
* The supported initialization parameters of this servlet are:
*
* - javax.jcr.Repository
* -
* Name of the servlet context attribute to put the repository in.
* The default value is "
javax.jcr.Repository".
*
* - org.apache.jackrabbit.rmi.client.LocalAdapterFactory
* -
* Name of the local adapter factory class used to create the local
* adapter for the remote repository. The configured class should have
* public constructor that takes no arguments.
*
* - location
* -
* Location of the remote repository in the JNDI directory.
* The default value is
* "
org/apache/jackrabbit/rmi/remote/RemoteRepository".
*
* - *
* -
* All other init parameters are used as the JNDI environment when
* instantiating {@link InitialContext} for looking up the repository.
*
*
*
* This servlet can also be mapped to the URL space. See
* {@link AbstractRepositoryServlet} for the details.
