[jboss-user] [Beginners Corner] - singleton ejb, loading classes from config.xml file?

Hello, I have a question regarding design in EJB. Should I use a singleton in my MDB or in stateless session beans. I have a servlet that calls a stateless session bean that calls a message driven bean. In the message driven bean constructor I call a singleton to set the mdb class variable. This singleton class reads the configuration file and initializes some framework classes. Is this ok to do initialization of classes from a configuration files and thus have singletons? In this configuration file I basically have something like a map between the xml message tab and the request class for that message and well as the action processor Thanks, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3988040#...
