All Implemented Interfaces:

FileSystem

public class DerbyFileSystem
extends DbFileSystem

DerbyFileSystem is a JDBC-based FileSystem 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 objects
• driver: 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: if true (the default) the database is shutdown when the last connection is closed; set this to false when using a standalone database

See also 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>
 

Field Summary

protected boolean

shutdownOnClose Flag indicating whether this derby database should be shutdown on close.
