Hi, Thanks for all the answers:
1. Actually I'm doing a JMX Bean, to start a pool of threads to ping the 1400 remote units we have. Problem with this approach: Not Portable and I don`t know how to implement something like a timer that calls the startPing Process method of my JMX bean every 15 minutes. So I'm not fully satisfied with this.
2. I really like the Connector approach because you can use threads, and is Portable, but the problem is that I don't know nothing about connectors, and I don't know if it requires much time to learn; time is always a problem. bbergquist, you've posted that yo've done a SNMP Connector, could you share some code with me? I'm really a newby in connector issues.
3. The EJB Timer approach was one of my thoughts, but I have a lot of pings to do, and we are not supposed to do Threads in that beans, do we?
4. ServletContextInitialized -> problems with cluster, so dismissed
