We have problem with Jackrabbit 1.3 repository. We run our repository in
websphere community edition and we use MSSQL. We are developing client which
runs on local computer and communicate with jacrabbit by RMI. Jackrabbit
runs on one server(Windows 2000) and MSSQL on another server(2000 too). We
can make connection to repository and import one file if we try to import
another file exceprion has been thrown:

Server started.

If we use file storage(objectPersistneceManager - or something similiar i
cant remember it exactly) instead of database everything goes right. It
looks like database or connection problem but we cant recognise it because
its exception in jackrabbit.

Thanks for help. Michal
