    - by Miau
    Scenario is very simple somewhere in the code I have this dynamic myVariable = GetDataThatLooksVerySimilarButNotTheSame(); //how to do this? if (myVariable.MyProperty.Exists) //Do stuff So basically the question is how to check (avoiding exceptions) that a certain property is available in my dynamic variable. I could do GetType() but I d rather avoid that, I dont actually want to know the type of the object I want to know if a property (or method if that makes life easier) is available Any pointers? Cheers

    - by mehmet6parmak
    Hi, I am trying to implement HttpSessionListener so that users of this listener can register implementation of ISessionEvent interface to session Events.code is below: public class MySessionListener implements HttpSessionListener{ @Resource ISessionEvent sessionEvent; public ISessionEvent getSessionEvent() { return sessionEvent; } public void setSessionEvent(ISessionEvent sessionEvent) { this.sessionEvent = sessionEvent; } @Override public void sessionCreated(HttpSessionEvent arg0) { sessionEvent.SessionCreated(arg0.getSession()); } @Override public void sessionDestroyed(HttpSessionEvent arg0) { sessionEvent.SessionDestroyed(arg0.getSession()); } } When user implement ISessionEvent and add as a bean, SessionCreated and SessionDestroyed functions of implementation will be called when these events occured. You can ask why dont you just write inside listeners methods, i dont i'm just trying. When i try the code above i got the following error message: javax.naming.NameNotFoundException: Name com.mehmet6parmak.sessionlistener.MySessionListener is not bound in this Context at org.apache.naming.NamingContext.lookup(NamingContext.java:770) at org.apache.naming.NamingContext.lookup(NamingContext.java:153) at org.apache.catalina.util.DefaultAnnotationProcessor.lookupFieldResource(DefaultAnnotationProcessor.java:278) at org.apache.catalina.util.DefaultAnnotationProcessor.processAnnotations(DefaultAnnotationProcessor.java:187) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4082) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4630) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardHost.start(StandardHost.java:785) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:445) at org.apache.catalina.core.StandardService.start(StandardService.java:519) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:581) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:289) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414) Resource annotation causes the error but i could not resolve it.
