Hi, > AFAIK JackRabbit uses Apache Derby
You can use any database (MySQL, PostgreSQL, H2 Database Engine, Oracle,...). Apache Derby just happens to be the default. > I would like to customize JR to access my DataBase Schema (a > couple of tables which save node types and node relations instead jackrabbit > repository). If you use your own custom schema, you would need to write your own JCR implementation (your own 'Jackrabbit'). Or at least your own Persistence Manager (see http://wiki.apache.org/jackrabbit/PersistenceManagerFAQ ). But that's quite a lot of work. Instead, I suggest to use Jackrabbit to store the node data, and use the regular MySQL Bundle Persistence Manager. > I use mysql to store the node info and a custom filestore to > store BLOB objects. I suggest to use the Data Store, see http://wiki.apache.org/jackrabbit/DataStore Regards, Thomas
