To me the only way I will ever use ASP.NET is with the castle monorail project cos that way I will use front controller design patern with C# and can still use the front controler design pattern with php (code igniter, cakephp) and also with java. so I will learn in php and apply knowledge in java and C# and also learn new things C# or java and apply the knowledge in php. all the front controller enabled frameworks use MVC approach. tell me what u think

php: code igniter, cakephp somphony
java: spring, hibernate, struts
C# : castel monorail, maverick

google for those projects and I bet u u will be able to build an application in java and convert it to php in one night if u understand how the projects and frameworks operate
