public class DerbyFileSystem extends DbFileSystem
DerbyFileSystem
is a JDBC-basedFileSystem
implementation for Jackrabbit that persists file system entries in an embedded Derby database.It is configured through the following properties:
url
: the database url of the form"jdbc:derby:[db];[attributes]"
schemaObjectPrefix
: prefix to be prepended to schema objectsdriver
: the FQN name of the JDBC driver class (default:"org.apache.derby.jdbc.EmbeddedDriver"
)schema
: type of schema to be used (default:"derby"
)user
: the database user (default:null
)password
: the user's password (default:null
)shutdownOnClose
: iftrue
(the default) the database is shutdown when the last connection is closed; set this tofalse
when using a standalone database
DbFileSystem
.The following is a fragment from a sample configuration:
<FileSystem class="org.apache.jackrabbit.core.fs.db.DerbyFileSystem"> <param name="url" value="jdbc:derby:${rep.home}/db;create=true"/> <param name="schemaObjectPrefix" value="rep_"/> </FileSystem>
