There are situations where JDK is banned in production and only JRE allowed for use. In this case if you are using JSP there is only one option to use - precompile JSP. Here is example how to achieve that. Nothing very special, but I guess this can save some time and effort for somebody )
<plugin>WarSourceExcludes will not package original JSPs - really makes no sence since they are just classes and appropriate servlet mappins in web.xml now.
