Don't set these environment variables.  They won't help and might  
break the geronimo login configuration mechanism.  At best they will  
be confusing.  If you have specific needs for them, that might  
require another discussion.

If you could outline the structure of the project and indicate  
exactly where you've specified the security realm that would be  
helpful. Since you mention ejbs I assume that you are deploying an  
ear. In geronimo, for an ear, there is one "ear" classloader that  
includes all the ejb jar and rar classes, together with the stuff  
pointed to by manifest class-paths, and then each web app gets  
another, child, classloader.  So, if the security realm definition is  
in the geronimo-application.xml or an openejb-jar.xml plan, all the  
classes it needs need to be in ejb jars, rars, or jars in the  
manifest classpath of these.  If the security realm definition is in  
the geronimo-web.xml then it can use classes from that war and the  
ejb jars and wars and manifest classpaths, but not other wars.

Hope this helps
