If you would 'upgrade' the templates to be more production-ready you would force the user into using certain design patterns that may not be compatible with his particular business requirements, for example the UID generator described below, suppose you need to work with an existing DB and all primary keys are required to be java.lang.Long ? I guess that one 'magical' template does not exist since each particular case is too different. btw, I am using the XDoclet UID generation: <utilobject includeGUID="true" cacheHomes="true" /> I removed the UID generator from the template (together with the caching of the homes...) I prefer XDoclet to generate that code for me. another 2 cents ;-) cheers Wouter. >My 2 cents, > >Jonathan > > > >>>> "Matthias Bohlen" <[EMAIL PROTECTED]> 03/28/03 11:30AM >>> >Hi Ian, > >as I stated in a previous email, this class is a perfect example for >inclusion into the Struts cartridge of AndroMDA.
