com.sun.ejb.containers.StatelessSessionContainer

This class provides container functionality specific to stateless SessionBeans. At deployment time, one instance of the StatelessSessionContainer is created for each stateless SessionBean type (i.e. deployment descriptor) in a JAR.

The 3 states of a Stateless EJB (an EJB can be in only 1 state at a time): 1. POOLED : ready for invocations, no transaction in progress 2. INVOKING : processing an invocation 3. DESTROYED : does not exist

This container services invocations using a pool of EJB instances. An instance is returned to the pool immediately after the invocation completes, so the # of instances needed = # of concurrent invocations.

A Stateless Bean can hold open DB connections across invocations. Its assumed that the Resource Manager can handle multiple incomplete transactions on the same connection.

     public boolean isUserInRole(String role) {
        Switch sw = Switch.getSwitch();
        InvocationManager mgr = sw.getInvocationManager();
        Object o = mgr.getCurrentInvocation().getContainerContext();
        if(o instanceof StatelessSessionContainer) {
            StatelessSessionContainer cont = (StatelessSessionContainer) o;
            boolean res = cont.getSecurityManager().isCallerInRole(role);
            return res;
        } else if (o instanceof WebModule) {
            WebModule webModule = (WebModule)o;
            Realm realm = webModule.getRealm();
