Hi Wouter, Thanks, Your XDoclet UID generation idea was what I was thinking about to make it more production ready. That's a change I'll be making soon to my templates.
Ultimately it doesn't matter to me since I'll be doing a bit of template modification myself, but I was thinking of people who are starting fresh with no predefined DB schema and just want to be able to get a feel for creating EJB applications with this way-cool EJB generator. Often apps that start out to be just prototypes end up as the production application. Something you'll learn about me is that I'm always trying to lower the "cost" of entry to any tool that I write or use. I'm looking foward to the plugin concept (it's been called something else, but I don't remember now) which should help much in that regard.

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.
