Re: [Springframework-developer] Optional dependencies

[Srikanth S <sri...@co...>]

Hi Rod

I don't think it would be a good idea to make developers depend on 
something like Struts. A good example would be  Jakarta commons logging 
which allows logging with different logging packages such as log4j, 
jdk1.4 etc.  without depending on unused packages. I do not think Struts 
needs any special treatment. As argued in your in book Struts is too JSP 
centric which is by far most ugly presentation mechanism. Going forward 
XML based transformations would be the  most popular way for 
presentation and we should do what ever it takes to make that more popular.
