NEWS Advanced Connection and Transaction Demarcation and Propagation The Java Persistence tutorial has been extended with a text explaining a more advanced way of demarcating the life span of connections and transactions in JDBC. It is this method that will soon be implemented in Butterfly Persistence, by the way. Butterfly DI Container 2.9.9-beta Version 2.9.9 contains support for using Butterfly Container as an internationalization mechanism for both components and texts. Butterfly Persistence 5.1.14-beta Version 5.1.14 contains support for creating and upgrading databases from within your application (or a separate application if you like). Conceptual Implementation of Tetris The Flex Tetris tutorials has been enriched with a new text explaining how to implement Tetris conceptually, meaning the rules and pseudo code behind the game. It is explained in a programming language independent fashion, so JavaFX programmers can also benefit from it.
