I added the below fix to RepositoryImpl.java and it works fine. I'm not sure if its the right fix though.

I copied the method setupSession() from RepositoryUtil and added it in RepositoryImpl.java. I call this method from the constructor after the call to createNamespaceRegistry. What this does is it registers the namespace for OCM upfront. Now if I already have data stored in a DB and I'm initializing the repository for the first time, it works smoothly during indexing as the namespaces for OCM have already been registered.

Please let me know your views on this. Thanks.

public static void setupSession(NamespaceRegistry nsReg) throws RepositoryException { try { /** namespace prefix constant */ final String OCM_NAMESPACE_PREFIX = "ocm";

/** namespace constant */ final String OCM_NAMESPACE = "http://jackrabbit.apache.org/ocm";

log.info("Setup Jcr session setup ...");

String[] jcrNamespaces = nsReg.getPrefixes(); boolean createNamespace = true; for (int i = 0; i < jcrNamespaces.length; i++) { if (jcrNamespaces[i].equals(OCM_NAMESPACE_PREFIX)) { createNamespace = false; log.debug("Jackrabbit OCM namespace exists."); } }

if (createNamespace) { nsReg.registerNamespace(OCM_NAMESPACE_PREFIX, OCM_NAMESPACE); log.info("Successfully created Jackrabbit OCM namespace."); }

} catch (Exception e) { log.error("Error while setting up the jcr session.", e); throw new RepositoryException(e.getMessage()); } }

The ancertor class used for the OCM unit tests should help. You will see how to init the ObjectContentManager correctly and in the correct order.

humm it time to make some docs :-(

But if I'm initializing the repository for the first time and trying to access objects that have already been persisted in the database, it fails because the OCM namespace entries havent been added yet. How do i specify the entries in this case? The RepositoryUtil class adds the entries for OCM but it hasnt been called yet.

Hi,

I'm not sure I understand the issue, but to me it looks like you forgot to copy the registered namespaces to the new location.

Hi,

I did some debugging on this and found that this issue arises because the namespace for OCM hasn't been registered yet. Its only after the Session is created that the RepositoryUtil class registers them. I think this problem doesn't occur with the org.apache.jackrabbit.core.persistence.db.OraclePersistenceManager as it doesnt create name index. I think the solution would be to register the OCM namespace as part of the NameSpaceRegistryImpl class itself. Please let me know what can be done regarding this.

Thanks.

Hi,

My persistence manager is

org.apache.jackrabbit.core.persistence.bundle.OraclePersistenceManager .

If there is some existing data in the DB and i try to initialize the repository for the first time, i get this exception. If i deleted everything and then try, it works fine. What could be going wrong?
