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