 ActiveRecord-JDBC-Adapter (AR-JDBC) is the main database adapter for Rails'
 *ActiveRecord* component that can be used with [JRuby][0].
 ActiveRecord-JDBC-Adapter provides full or nearly full support for:

-add support **MSSQL**. Unless we get more contributions we will not be going
-beyond these four adapters.  Note that the amount of work needed to get

-that adapter continues to work is not something we can do with the resources
