Hi Aslak, thank you for sharing your ideas on this.
I have also read the message by Ludovic Claude [[EMAIL PROTECTED]] on the middlegen-devel list and some weblog entries on the Net. I'd like to keep the solution as simple as possible. If the Velocity template does the job, it's OK. We can refactor later if it should become necessary. About IDE integration: We have just developed a commercial plug-in for the Poseidon CASE tool that drives the UML2EJB code generator from the active UML model. Poseidon, again, is integrated with the Netbeans IDE (or SUN One Studio?). Personally, I prefer Eclipse (one window only, not many tiles) but the Poseidon guys have planned that for some later release. Anyway, we should integrate at the meta-info level, not at the GUI level. Some GUI integration may drive ant, which in turn drives UML2EJB. Middlegen has its own GUI, right? Maybe this can be integrated as an Eclipse plug-in? The plug-in API is said to be relatively easy to handle. Who knows? Would be interesting if you showed me the Velocity template for XMI. Can you email it? Cheers... Matthias P.S.: Do you chat on Yahoo messenger with voice support? ---- Matthias Bohlen Consulting that helps project teams to succeed...
