We are using jspc ant task to pre-compile JSP files into classes/(then package into war)
Now we are switching to Jetty 8. According to the doc, there exists a maven
From your first sentence you are apparently already using an ant task to pre-compile the jsp files...so using jetty-8 doesn't mean you have to change that process at all, you will still just pre-compile as you have been, building your war file as you have been and then just deploy into jetty-8. You will need to add jsp to the OPTIONS in the start.ini to get the jsp engine into the server classloader.
