Class JNDIConnectionSource

All Implemented Interfaces:
ConnectionSource, Component, org.apache.log4j.spi.OptionHandler

public class JNDIConnectionSource extends ConnectionSourceSkeleton
The JNDIConnectionSource is an implementation of ConnectionSource that obtains a DataSource from a JNDI provider and uses it to obtain a Connection. It is primarily designed to be used inside of J2EE application servers or application server clients, assuming the application server supports remote access of DataSources. In this way one can take advantage of connection pooling and whatever other goodies the application server provides.

Sample configuration:

    <connectionSource class="org.apache.log4j.jdbc.JNDIConnectionSource">
        <param name="jndiLocation" value="jdbc/MySQLDS" />
    </connectionSource>
  

Sample configuration (with username and password):

    <connectionSource class="org.apache.log4j.jdbc.JNDIConnectionSource">
        <param name="jndiLocation" value="jdbc/MySQLDS" />
        <param name="username" value="myUser" />
        <param name="password" value="myPassword" />
    </connectionSource>
  

Note that this class will obtain an InitialContext using the no-argument constructor. This will usually work when executing within a J2EE environment. When outside the J2EE environment, make sure that you provide a jndi.properties file as described by your JNDI provider's documentation.
