Prerequisit Question on SWF2

[mczauz]

I have a simple question. Does SWF2 require JEE5? I'm trying to setup SWF2 to work with WebSphere 6.0.x and am getting NoClassDefFoundError exception for ELContext class. This occurs when the servers start up and initializes the spring servlet. Below are the exceptions that I'm getting. Any help would be greatly appreciated.
