Hello, since the day I started looking for Flex Remoting, I have encountered the frameworks like Weborb, zend, amfphp. I am not choosing amfphp because someone told me that it is now dead and no one is working on it. Not even Zend because of the complexity. And finally choose weborb for php.

However, since I am new to weborb and flex itself. I first wanted to learn how the remoting works, the fundamentals and the architecture. I still could not find the answer because every tutorials/articles explain using one of the frameworks and I wonder is it possible to send/receive data without using any frameworks? Is there any good tutorial/article helps me to understand the fundamentals?

My second request is to help me understand weborb. The tutorials and articles goes the same way that I have explained. Is there any document/tutorial/article which explains what are the 3 xml files are inside the WEB-INF\flex\ and some explanation of the structure of the document and the elements/nods in it?
