good advice
if the container is going null could you provide
a complete dump of log
Directory of $CATALINA_HOME/logs
catalina.2009-07-01.log
display any/all messages that say anything about configuring Web Container e.g.
INFO: Configuring SomeWebApp for Web Container type 'MyTomcat'
all of the contents of HOST.YYYY-MM-DD.log e.g.
07/01/2009 02:42 PM 914 localhost.2009-07-01.log
vendor and version of webapp container you are using
JDK/J2EE version you are implementing e.g. java -version
any tweaks on JAVA_OPTS
as much code as is necessary to reproduce (including
web.xml,struts.xml,struts-default.xml)
thanks,
Martin Gainty
