Hi Friends

I know servlets to some extent but I am new to listener...My question is (may be very silly) if I want to add listeners to more than one event like ServletContextEvent and HttpSessionEvent and I have the listener classes in different files,then how can I declare both the classes in DD. Can I put 2 listener-class tags like



Or is there some other way?...Advance thanx...

You can add as many as you'd like.

but it should be

<!ELEMENT listener (listener-class)> *

u can have one and only one listener-class in listener.

if you have 2 listeners mySessionListener and myContextListener then in DD u would declare them as

<listener>
<listener-class>mySessionListener</listener-class>
</listener>

<listener>
<listener-class>myContextListener</listener-class>
</listener>

Notice that we have 2 separate listener elements. Its not 2 listener-class in one listener element.

Hope this makes it clear.
