Base Template Screens should extend this class and override the buildTemplate() method. Users of the particular service can then override the doBuildTemplate() for any specific pre-processing. You can also override the doBuild() method in order to add extra functionality to your system, but you need to make sure to at least duplicate the existing functionality in order for things to work. Look at the code for the doBuild() method to get an idea of what is going on there (it is quite simple really).<P><DL><DT><B>Version: </B><DD>$Id: TemplateScreen.java,v 1.1.1.1 2001/08/16 05:08:36
