[OFBiz] Dev - Devolopment IDE / editing Classes at runtime

[Danny Gaethofs]

Michael,

I tried out OFBIZ half a year ago with a lot of
difficulties to get it working. Since then I have been
looking at other applications written in Java and
deployed on Tomcat.

I have been reading this and other threads about
Tomcat for the last hour. Now I begin to understand a
lot of things I did not captured before. As I was  new
(still am) to using all of this stuff, Tomcat, Java,
OFBIZ.

I have some experience with one of the upcoming
commercial ERP application build on an object oriented
IDE. I am not saying OFBIZ should work the same but
this environment has some strong features for a
developer. 

My idea is to have:
1. Separation between the application and the IDE and
the container/application server (whatever it is
called)

2. Ability to modify and compile classes, data
definition from within the IDE without having to log
out of the application.


Regards,
Danny
