The JDBC cache loader was not designed for direct manipulation of the tables using inserts, since it encodes data as byte streams (complete with versioning bits, etc). If you want to be able to manipulate the tables by hand - or some other process - I would recommend you write your own cache loader implementation, perhaps by extending the JDBCCacheLoader or AbstractCacheLoader.
