iLabs mobile toolbox is a set of libraries and demo applications for Java ME. It includes libraries for XMPP, feed reading, and highly functional and fast, but limited, rendering of HTML with some CSS. The OpenMiniBrowser demo application shows some of the potential of the HTML renderer. It is intended to be embedded in other applications, but may also be used as a standalone browser. The toolbox also includes "the Widger": a HTML and XML based application that allows much of the application logic to reside on a server, while the user interface is a true Java ME application and not just Web pages.
