When I deploy xWiki to an Oracle Application server 10.3 and try to access the Wiki I get a 500 internal server error.

From what I can find out it is related to the security around Oracles JMX and the MBeans in xWiki, but I cann't seem to find a way to fix it.

Indeed you need to allow XWiki some privileges if you run with a Java Security Manager. I've added info here to better explain this: http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HInstalland... Hope it helps, -Vincent
