The class reloading feture in T5 is a great productivity gain, for a T4 project I myself created an hibernateSessionFactory implementation that resides in tomcat's class loader so I don't need to wait for hibernate to initialize. this was small improvement but not near to desired speedup.
Question for Howard: With the current expirience with reloading page classes, what is a possibility for any of the commiters to implement a similar feature back to T4 ? is it: Hard, possible or impossible to implement ? Davor Hrg On 5/15/07, Inge Solvoll <[EMAIL PROTECTED]> wrote:
Thanks anyway, Matt! I've done some experimenting, what actually works (most of the time) is to recompile a class without structural changes. If you change a method name or parameter, you have to reload the application. Some people say Jetty have better performance and better support for configuring the class reloading you want, does anyone here have experience with that?
