Package org.apache.log4j.db

The org.apache.log4j.db package provides means to append logging events into various databases. The persisted data can be later read back using DBReceiver.

Most popular database systems, such as PostgreSQL, MySQL, Oracle, DB2 and MsSQL are supported.

Just as importantly, the way for obtaining JDBC connections is pluggable. Connections can be obtained through the tradinal way of DriverManager, or alternatively as a DataSource. A DataSource can be instantiated directly or it can obtained through JNDI.

CustomSQLDBReceiver	Converts log data stored in a database into LoggingEvents.
DataSourceConnectionSource	The DataSourceConnectionSource is an implementation of ConnectionSource that obtains the Connection in the recommended JDBC manner based on a DataSource.
DBAppender	The DBAppender inserts loggin events into three database tables in a format independent of the Java programming language.
DBHelper
DBReceiver
DriverManagerConnectionSource	The DriverManagerConnectionSource is an implementation of ConnectionSource that obtains the Connection in the traditional JDBC manner based on the connection URL.
JNDIConnectionSource	The JNDIConnectionSource is an implementation of ConnectionSource that obtains a DataSource from a JNDI provider and uses it to obtain a Connection.
