Installation problem with jackrabbit webapp and oc4j
When I try to deploy jackrabbit-webapp-1.4.war using Oracle Containers for J2EE 10g (10.1.3.1)
I get the following exception when I try to browse the repository using the following link
http://localhost:8888/jackrabbit-webapp-1.4/repository/default/
java.lang.NullPointerException

Are there any oc4j configuration settings that I set up to deploy this war file?
I also noticed that the 2 cluster tables were not created (the other 8 tables were created).
As a side issue the welcome.jsp failed to compile as it did not recognise the log symbol at line 27.
I just commented this line out for now.
Are there any other jars that I need to add to the class path for oc4j?
Thanks

Can you try it with a version from Jackrabbit trunk? It may not fix
the issue entirely, but at least it'll give a more accurate error
message instead of the NPE you're seeing now.

I don't think it is a credentials issue as the same repository.xml file deploys on Tomcat ok.

The NullPointerException here is caused by issue JCR-1678 [1] that's already fixed in Jackrabbit trunk.
However, the NPE hides some other problem. It looks like the webapp is unable to acquire a repository session. This could either be caused by the repository not being available or by some other issue in logging in to the repository. It could be something as simple as incorrect credentials.

The log method in question is expected to come from the GeneralServlet base class, but apparently in oc4j the JspPage implementation class does not inherit from GeneralServlet. We probably shouldn't make such expectations in Jackrabbit. Can you please file a bug report about this?
> Are there any other jars that I need to add to the class path for oc4j?
Adding the jcr-1.0.jar should be sufficient.
