The rise of application frameworks targeted to the Web has also changed the way in which we develop web applications. Application code written in servlets is rapidly being replaced with application code further abstracted from the base model using frameworks such as JSF. When working in an environment such as this, basic application persistence issues, such as where to acquire and store the entity manager and how to effectively use transactions quickly, become more challenging. Although we will explore some of these issues, persistence in the context of a framework such as JSF is beyond the scope of this book. As a general solution, we recommend adopting a session bean component model in which to focus persistence operations. Session beans are easily accessible from anywhere within a Java EE application, making them perfect neutral ground for business services. The ability to exchange entities inside and outside of the session bean model means that the results of persistence operations will be directly usable in web frameworks without having to tightly couple your presentation code to the persistence API.

// create message font msgsFont = new Font("SansSerif", Font.BOLD, 24); } // end of ShiftBGCanvas3D() The drawing surface is a BufferedImage called drawIm, and its associated graphics context is called drawg2d. The background will often be composed from two copies of the background picture, and these images need to be combined into a single visual before being rendered by drawAndFlushImage() in preRender(). The drawing surface is used for this composition. The foreground consists of two overlays: the Moves text and the translucent title. They re combined into a single image in postRender() by writing them onto the drawing surface and calling drawAndFlushImage(). These composition tasks could be assigned to two separate drawing surfaces one for the background, one for the foreground but it s straightforward to reuse the same surface. The drawIm BufferedImage is of type BufferedImage.TYPE_4BYTE_ABGR, which includes an alpha channel. This means that transparent or translucent images will be rendered correctly. Efficiency is another reason for using BufferedImage.TYPE_4BYTE_ABGR. If OpenGL is the underlying graphics API, drawIm can be rendered without drawAndFlushImage() having to make a copy of it. backIm contains the basic background image, a sunset, shown in Figure 8-19.
