Class DbFileSystem

    DbFileSystem is a generic JDBC-based FileSystem implementation for Jackrabbit that persists file system entries in a database table.

    It is configured through the following properties:

    • driver: the FQN name of the JDBC driver class
    • url: the database url of the form jdbc:subprotocol:subname
    • user: the database user
    • password: the user's password
    • schema: type of schema to be used (e.g. mysql, mssql, etc.);
    • schemaObjectPrefix: prefix to be prepended to schema objects
    The required schema objects are automatically created by executing the DDL statements read from the [schema].ddl file. The .ddl file is read from the resources by calling getClass().getResourceAsStream(schema + ".ddl"). Every line in the specified .ddl file is executed separatly by calling java.sql.Statement.execute(String) where every occurence of the the string "${schemaObjectPrefix}" has been replaced with the value of the property schemaObjectPrefix.

    The following is a fragment from a sample configuration using MySQL: 

       <FileSystem class="org.apache.jackrabbit.core.fs.db.DbFileSystem">
       <param name="driver" value="com.mysql.jdbc.Driver"/>
       <param name="url" value="jdbc:mysql:///test?autoReconnect=true"/>
       <param name="schema" value="mysql"/>
       <param name="schemaObjectPrefix" value="rep_"/>
   </FileSystem>

       <param name="driver" value="com.microsoft.jdbc.sqlserver.SQLServerDriver"/>
       <param name="url" value="jdbc:microsoft:sqlserver://localhost:1433;;DatabaseName=test;SelectMethod=Cursor;"/>
       <param name="schema" value="mssql"/>
       <param name="user" value="sa"/>

    The following is a fragment from a sample configuration using Ingres: 
       <FileSystem class="org.apache.jackrabbit.core.fs.db.DbFileSystem">
       <param name="driver" value="com.ingres.jdbc.IngresDriver"/>
       <param name="url" value="jdbc:ingres://localhost:II7/test"/>
       <param name="schema" value="ingres"/>
       <param name="user" value="ingres"/>
       <param name="password" value="ingres"/>
       <param name="schemaObjectPrefix" value="rep_"/>
   </FileSystem>
    The following is a fragment from a sample configuration using PostgreSQL: 
       <FileSystem class="org.apache.jackrabbit.core.fs.db.DbFileSystem">
       <param name="driver" value="org.postgresql.Driver"/>
       <param name="url" value="jdbc:postgresql://localhost/test"/>
       <param name="schema" value="postgresql"/>
       <param name="user" value="postgres"/>
       <param name="password" value="postgres"/>
       <param name="schemaObjectPrefix" value="rep_"/>
   </FileSystem>
    JNDI can be used to get the connection. In this case, use the javax.naming.InitialContext as the driver, and the JNDI name as the URL. If the user and password are configured in the JNDI resource, they should not be configured here. Example JNDI settings: 
     <param name="driver" value="javax.naming.InitialContext" />
 <param name="url" value="java:comp/env/jdbc/Test" />
