Category: ejbdoclet Group: None Status: Open Priority: 5 Submitted By: Andrew Stevens (stevensa) Assigned to: Andrew Stevens (stevensa) Summary: Improvements to BMP DAOs Initial Comment: I'm looking at improving the DAO stuff for BMP entity beans, in particular, I'm thinking of making it work more like the dataobjects. Specifically: - adding a template and/or subtask for generating the DAO interfaces (CustomerDAO.java in the samples), with an @ejb:dao class level tag in the bean class to control its generation. You then code the DB-specific subclasses for these (CustomerExampleDAO.java), inheriting from them. (to avoid compilation errors in your subclasses when new dao methods are added, perhaps the template should generate an abstract class with empty methods (or ones that throw an SQL exception) rather than an interface? - in the BMP template, it can check for whether a DAO is being used (similar to ifIsWithDataContainer) and automatically add the calls to the DAO into the generated ejbLoad etc. rather than having to code it in the bean class like CustomerBMPBean.java does. - the @ejb:dao tag can specify the env-entry to use for looking up the actual class, so we don't need to include getDAO() with an @ejb:dao-method tag in the bean class. - in fact, this means all mention of the dao can be removed from the bean class. So you could then switch from using BMPs with DAOs to CMP without changing any code, just switch the tag to @ejb:bean type="CMP" - and, ideally, it'll work with the "component inheritence" so I can have all my entity EJBs inherit from an abstract superclass, and using DAOs that inherit from an abstract DAO (with the PK and findAll finders being declared in the abstract DAO superclass). Any comments/suggestions/improvements? (especially from Vincent, since he checked in the existing bits) ---------------------------------------------------------------------- You can respond by visiting: http://sourceforge.net/tracker/?func=detail&atid=402707&aid=514224&group_id=31602 _______________________________________________ Xdoclet-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/xdoclet-devel
