wingS is a servlet development framework for Web applications. It features Swing-like components and utilizes Swing models, Swing events, and a very similar API. A special LayoutManager allows you to place components using designer provided HTML templates. The HTML code generation of the components themself supports PLAF (Pluggable Look and Feel), so it is possible to create a different output, like plain HTML, HTML+CSS, and WML.
HenPlus is a SQL shell written in Java that works for any database that has JDBC support. It provides commandline history, commandline completion, and can handle multiple connects to different databases at once. Database-independant table dumps, aliases, and variables are also supported.
