(I know how to create threads). I would advise you not to create your own threads. Instead, use a thread pool and queue your jobs into that. 3rd-party thread pools exist, or you can use the ones available in Java 1.5+ in the java.util.concurrent package. You can get started by reading the javadoc for java.util.concurrent.ThreadPoolExecutor and going from there. > So Tomcat has nothing like this in itself? Any trick , shortcut?

Another option would be to queue the job in a database, then run a completely separate process to go and process them batch-style. This solution can even process jobs that were queued but not processed before you took the server down for some reason. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAksBvL4ACgkQ9CaO5/Lv0PDOYACfbdxU+QpIuwSz06Z0c/HHFUjs Pq0An3fNU9rGzjc2YZnFrw4E4TY4ngf7 =xAyX -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
