It sounds like your class is representative of a factory pattern, albeit with some synchronisation. Is this correct? If so, you could: (a) Use a ServletContextListener to instantiate the class. It will need to be defined in your web.xml appropriately. This is an appropriate place to 'shutdown' the factory as well. or (b) Use one of the many frameworks that instantiate stuff for you. e.g. Spring Framework. Spring will do this in a webapp, standalone or testing context with no change to your actual class. To the best of my knowledge, most inversion-of-control frameworks (like Spring) use the ServletContextListener approach for instantiation in a web application. If you go for option (b) you should consider whether simply to use the framework only and drop your factory class (if that's possible). > > thanks > -- Best Regards, Brett --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
