JnlpMultiView adds support for JNLP files, also know as Java Web Start, to NetBeans. It includes File Templates which you can access over 'New File...' and a visual editor like the one know from Web Projects for web.xml files. The visual editor shows you tooltips if you move with the mouse over the components, so you don't need to browse the Java Deployment Guide if unsure about one tag.

To run JnlpMultiView you need NetBeans 5.0 and J2SE 1.4 or above.

Feel free to contact me if you have ideas or problems with the module.
