Package org.apache.log4j.db

Class DriverManagerConnectionSource

  • All Implemented Interfaces:
    ConnectionSource, Component, org.apache.log4j.spi.OptionHandler
    public class DriverManagerConnectionSource
extends ConnectionSourceSkeleton
    The DriverManagerConnectionSource is an implementation of ConnectionSource that obtains the Connection in the traditional JDBC manner based on the connection URL.

    Note that this class will establish a new Connection for each call to getConnection(). It is recommended that you either use a JDBC driver that natively supported Connection pooling or that you create your own implementation of ConnectionSource that taps into whatever pooling mechanism you are already using. (If you have access to a JNDI implementation that supports DataSources, e.g. within a J2EE application server, see JNDIConnectionSource). See below for a configuration example that uses the commons-dbcp package from Apache.

    Sample configuration:

         <connectionSource class="org.apache.log4j.jdbc.DriverManagerConnectionSource">
        <param name="driver" value="com.mysql.jdbc.Driver" />
        <param name="url" value="jdbc:mysql://localhost:3306/mydb" />
        <param name="username" value="myUser" />
        <param name="password" value="myPassword" />
     </connectionSource>

    If you do not have another connection pooling mechanism built into your application, you can use the commons-dbcp package from Apache:

         <connectionSource class="org.apache.log4j.jdbc.DriverManagerConnectionSource">
        <param name="driver" value="org.apache.commons.dbcp.PoolingDriver" />
        <param name="url" value="jdbc:apache:commons:dbcp:/myPoolingDriver" />
     </connectionSource>
    Then the configuration information for the commons-dbcp package goes into the file myPoolingDriver.jocl and is placed in the classpath. See the commons-dbcp documentation for details.
