Note: change the <version> tag value to match your prefered jetty jspc plugin release.
New configuration parameters will be available from jetty-6.1.10 onwards, to allow you to control the file extensions of the jsps which are compiled. Here's an example:
The above would compile all jsp files in the webapp with extensions of .foo and .bah, but ignore those with .roo and .bar extensions. This can be useful if you have chosen something other than the usual .jsp and .jspx file extensions.
For a full listing of the <configuration> items supported by this plugin, see jspc parameter reference.
