seeking help with jackrabbit-jcr-servlet component

[Betty Chang-3]

Hi --

I'm trying to write a simple webapp that sits in the same tomcat servlet container as the jackrabbit server.  I want to
use this app to configure some custom nodetypes for the repository.

I'm trying to understand the instructions on the local.jsp page about the jackrabbit-jcr-servlet component.  In particular, it states:
"See the jackrabbit-jcr-servlet documentation for more details. "  

Where is the jackrabbit-jcr-servlet documentation?  

Is it possible for me to use the line of code shown in the local.jsp page to access a repository in the jackrabbit app if my webapp is on
the same container?  Will I  be able to add custom node types this way?    I tried the example, but I ended up with an error about my
context missing the "javax.jcr.repository" attribute.

Thanks

Betty

See the org.apache.jackrabbit.servlet javadocs in
http://jackrabbit.apache.org/api/1.4/.

Yes if you your webapp has cross-context access to be able to access
the repository from the jackrabbit-webapp context. In Tomcat that
requires a <Context crossContext="true"/> setting.

Yes if the jackrabbit-api extension interfaces are shared within the
container. In Tomcat (6.x) that requires moving the jackrabbit-api jar
file from WEB-INF/lib in jackrabbit-webapp to $CATALINA_HOME/lib.

Are you using the jackrabbit-jcr-servlet classes like
ServletRepository to access the repository? Then instead of the code
snippet in local.jsp you should be using the ContextRepositoryServlet
that copies the repository reference from another context to the
context of your webapp.

Another point, the default attribute name is "javax.jcr.Repository" (capital R).

Hi --

So, here's what I tried:

I created a servlet that extends ContextRepositoryServlet,  for which the
init-param "path" is set to the context path of the
source servlet ("/jackrabbit").   In the init() for this servlet, I did a
Repository rep = new ServletRepository(this).

Then, when I tried a session = rep.login(), I got the following exception:
javax.servlet.ServletException: javax.jcr.RepositoryException: Invalid
repository: Attribute javax.jcr.Repository in servet context Jackrabbit JCR
Server is an instance of
org.apache.jackrabbit.commons.repository.ProxyRepositoryAm I even on the
right track?

Thanks

Betty

Hi --

Okay, I sorted out my last problem.  I moved all of my jackrabbit lib jar
files into the tomcat/lib folder so that it is shared
among the two different webapps.  Otherwise, the "instanceOf Repository"
fails inside the ContextRepositoryFactory.java code.
