Hi, This error occurs in the following scenarios.
If you insert a object into the JackRabbit repository with the org.apache.jackrabbit.core.persistence.bundle.OraclePersistenceManager persistence manager into the repository. The bundle persistence manager creates temporary indexes in the repository homedir. If I try to run the OCM program to get a particular object from the repository on a different machine where the temporary indexes doesn't exists it throws this error >> >>> Caused by: java.io.IOException: Error indexing root node: >> >>> 7107e03e-aefb-4663-9cf5-1663e665bb5f This particularly happens because of the OCM namespace doesn't gets register while creating the temporary indexes for the first time and it tries to create the indexes as the objects are already present into the repository.

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()); } } Christophe Lombart wrote: > > The ancertor class used for the OCM unit tests should help.
