I was able to get this working again after I deleted my project's 'packaging-build.xml' file. Not exactly sure why as I haven't had the time to look further, but it worked.
how to pre-compile jsp , i enable jsp compilation support in project property
it creats EMPTY folders
what configuartion i missed .....
The JSP Compilation support doesn't pre-compile JSPs for you. As far as I know, JBoss-IDE doesn't have anything to do with that. If you need to precompile JSPs you will need to use JSPC to do it. If you use Ant I know it has a built in Jspc task that'll do it with some work.
