Hi! I am responsible to maintain one server running a J2EE web application. Jboss 4.0 is used as servlet container and the JVM is started with memory enough to run the application (I think): if [ "x$JAVA_OPTS" = "x" ]; then JAVA_OPTS="-server -Xms1500m -Xmx1500m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval...

I've got a custom login module in an ear on jboss. The ear's META-INF has a jboss-app.xml which points at a login-service.xml which contains an mbean that points to a login-config.xml which defines the custom login module. The jboss.xml in the ear's META-INF uses the same security-domain as that defined for the login module in login-con...
