[SNMP4J] SNMP4J receiving traps in J2EE application server

[Mathias Bogaert]

Steve,

Use a ServletContextListener:

http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/ 
ServletContextListener.html

in the contextInitialized method, start the SNMP stack.

and in web.xml:

     <listener>
          
<listener-class>your.listener.here.StartupListener</listener-class>
     </listener>
