Just realized my reply doesn't goes through the mailing list, reposted here.
Hi, thanks for the reply. Sorry If I'm not clear enough with my question. Lets say I have a hashtag entity that i stored in the database and managed by HashtagDAO (a tapestry service). And then i have a TwitterParserService that check if a tweet contain a hashtag that i saved in the database. The problem, if someone add or changed the hashtag in the database i want the TwitterParserService to immediately know about the change and check the tweet using the new hashtags. In j2se it will be a straight forward pub-sub/observer pattern. Just create an interface for the listener, let the TwitterParserService implement it and set as the default listener, and invoke it from HashtagDAO. But i don't think it would work with tapestry services class. I could do some kind of pooling mechanism. But i think a pub-sub mechanism would be better. Using Rabbit MQ or JMS feels like an over engineer solution for this simple case. Thanks.
