i'm in beijing. our project based on j2ee had been built for almost one year, but upon to two months ago, i decided to transfer it to MVC frame. so these days i studied MVC very hard, and now i think i have got somewhat spirit into it. btw, one year ago i experienced IBM Websphere, but it need so much system resources (at least > 512MB for WAS, and >256MB for WAS studio), then i decided to use Weblogic5.1+JBuilder4. as i am going to use MVC, we should share the experiences each other, do you mind?
