Bottomline 1.2

Bottomline is a JDBC Bridge API that loads database drivers directly from JAR archives with (JCL) Jar Class Loader. Bottomline uses a jdbc:bottomline bridge to load multiple drivers from their respective JAR files. Unlike JDBC, Bottomline uses custom class loaders to load drivers completely bypassing JVMs bootstrap class loader. This gives an advantage to load multiple versions of the same database driver from different JAR files.
Overview
Bottomline is a JDBC Bridge API that loads database drivers directly from JAR archives. Bottomline uses a jdbc:bottomline bridge to load multiple drivers from their respective JAR files. Unlike JDBC, Bottomline uses custom class loaders to load drivers completely bypassing JVMs bootstrap class loader.
Bottomline helps to load multiple database drivers using separate class loaders.
Multiple versions of the same database driver can be loaded from different JAR files.
Developers can build applications using conventional JDBC and transparently use Bottomline underneath.
Bottomline seamlessly integrates with applications servers like JBoss and can be bound in JNDI which allows connections to be pooled using the application servers Connection Pooler.
Bottomline also works well with persistence frameworks like iBATIS.
