Class JNDIConnectionSource
java.lang.Object
org.apache.log4j.spi.ComponentBase
org.apache.log4j.db.ConnectionSourceSkeleton
org.apache.log4j.db.JNDIConnectionSource
- All Implemented Interfaces:
- ConnectionSource, org.apache.log4j.spi.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 DataSource
s. 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.
