Currently the weblogic.xml file specified in the installation notes is specific for weblogic 8.x and although this will still deploy in Weblogic 9.x, we should consider updating the documentation to use the Weblogic 9.x style deployment descriptor when deploying on Weblogic 9.x

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90">
	<jsp-descriptor>
		<page-check-seconds>-1</page-check-seconds>
		<precompile>false</precompile>
		<working-dir>./jsp_precompile_dir/jira</working-dir>
	</jsp-descriptor>
	<container-descriptor>
		<servlet-reload-check-secs>-1</servlet-reload-check-secs>
	</container-descriptor>
	<context-root>jira</context-root>
</weblogic-web-app>

Additionally the links to BEA/Oracle's weblogic.xml documentation points specifically to Weblogic 8.x documentation which is slightly different to that of Weblogic 9.x.
