I have eneterprise application with structure like that:


my-application.ear
|
web-app.war
|
some-other.jar
|
META-INF(with files: application.xml, jboss-app.xml)


jboss-app.xml contains following content

<?xml version="1.0"?>
<jboss-app>
<security-domain>java:jaas/portal</security-domain>
</jboss-app>



In web-app.war in WEB-INF directory there is a file jboss-web.xml with following content

<?xml version="1.0"?>
<jboss-web>
<security-domain>java:jaas/portal</security-domain>
</jboss-web>


In web-app.war I defined both portlet and servlet. Portlet use servlet to generate some content. I checked that both portlet and servlet get the same session Id.
But there is a problem to get information about remote user. When I log into portal, in portlet I get remote user (request.getRemoteUser()) but in servlet I get null.

What I did wrong, or what should I add to my configuration to have possibility to get remote user in both servlet and portlet? I use Jboss-Portal 2.6.3.GA.
