Hi, It's been quiet on the list lately, but development is still in progress. I've mostly been busy working on the hibernate layer in webical. It kept giving problems like NonUniqueObjectExceptions, LazyInitializationExceptions and really weird lockups without any explanation. I've tried to solve this while still reusing the Spring DaoSupport and other facilities, but it wouldn't behave properly so I've ditched it together with the OpenSessionInviewFilter. The setup is now a lot simpler. A dao implementation subclasses a general class (BaseHibernateImpl) with all kinds of support methods (much like HibernateDaoSupport). The sessionmanagement is based on an aspect and an annotation. Each method marked with the @Transaction annotation is wrapped with the necessary code to setup and flush the session. It seems to work really good and its simple to avoid all the before mentioned problems by keeping the marked methods really simple and small. The daos are still to be cleaned up a bit, but it seems a step in the right direction. Other recently added things: - Jetty and webdav-servlet integration in the unit tests. Now we don't need internet to run the unit tests. Jetty is started with a clean webdav root before each test. This also means no more failures because test ran halfway through and the ics is left in a messed up state. - A fixed user id for development purposes. This way developers don't need to log in after each restart - Jetty launch for development with an integrated webdav-servlet with one ics in the webdav root. See developers-readme.txt for Jetty vs tomcat setup. - A database bootstrap configuration in src/main/webapp/applicationContext-bootstrap. Configuration is inserted in the database on each startup. - Encryption in the database for passwords. Planned in the near future: - An Aspect to catch LazyInitializationExceptions and reattach the Object to the current Session - Usage of hsqldb or Apache derby for development - Refactoring of the Ajax dayview Regards, Ivo -- Ivo van Dongen Func.
