  • If you want to use RMI to communicate between your java applet and java servlet, you need to be aware that microsoft has deilberately disabled RMI in its IE5 browser. There is a patch, but it's easier (and better) to install the JRE plugin from sun. For more details of plugins look here. You also need to know that in order to use the JRE to run your applets, you must convert your HTML code so that it uses OBJECT tags rather than APPLET tags. The plugin page (see previous link) has a converter that can be useful if you've already written lots of html that you want to convert - otherwise, it's possibly easer to usethe OBJECT tags from the start (see here).
• jCharts. jCharts is 100% Java based charting utility that outputs a variety of charts. This package is ideal for displaying charts via Java Servlets.
