External scripts really are the best answer for this. It is not possible to 'PUSH' information like this without a dedicated client!
>>> [EMAIL PROTECTED] 12-21-2004 10:14 >>> Hi, I'm having a similar problem in my application. I've got several servlets called by the users. Every requets save some information in DB, that has to be sent to another server later and in a compress format. So I need sth similar toShilpa is asking, a process which runs every X minutes to recover the information and send it to the Server. My solution to this problem was to implement a "ServletContextListener" inside Tomcat. When Tomcat starts my application the "contextInitialized" method is called, and then a thread is started to do the task explained above. I use "Thread.sleep(step)" to wait for the next execution. I didn't find anyway to set a timer for a servlet, and I didn't like the option of creating an external script . Any other suggestions to solver this problem?

I once wrote a shell script that calls a http address on the local machine but cannot remember how ;) if you are using oracle then you can setup this timer thread inside the database itself. don't add a thread into your web application. >> >> >> > >I concur.
