I tested this code:
I added these lines in shiro.ini
cacheManager = org.apache.shiro.cache.MemoryConstrainedCacheManager
securityManager.cacheManager = $cacheManager
I tested this managed bean:
import java.io.Serializable;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.util.Collection;
import javax.faces.view.ViewScoped;
import javax.inject.Named;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.session.Session;
import org.apache.shiro.session.mgt.DefaultSessionManager;
import org.apache.shiro.web.session.mgt.DefaultWebSessionManager;
@Named
@ViewScoped
public class ActiveAccounts implements Serializable
{
public Collection<Session> listAccounts() throws
IllegalAccessException, NoSuchMethodException, IllegalArgumentException,
InvocationTargetException
{
DefaultSecurityManager manager = (DefaultSecurityManager)
SecurityUtils.getSecurityManager();
DefaultWebSessionManager sessionManager =
(DefaultWebSessionManager) manager.getSessionManager();
// invoke "sessionManager.getActiveSessions()" via reflection:
Method getActiveSessionsMethod =
DefaultSessionManager.class.getDeclaredMethod("getActiveSessions");
getActiveSessionsMethod.setAccessible(true);
Collection<Session> activeSessions = (Collection<Session>)
getActiveSessionsMethod.invoke(sessionManager);
return activeSessions;
}
}
But when I run this code I get
javax.faces.el.EvaluationException: java.lang.ClassCastException:
org.apache.shiro.web.session.mgt.ServletContainerSessionManager cannot
be cast to org.apache.shiro.web.session.mgt.DefaultWebSessionManager

Can you give some advice how to fix it?
