I am a newcomer to JSPs, and have been experimenting with writing them at
work. We are trying to build a web-based application and would like to
follow the MVC architecture, and would like to generate our pages using
jsps. After I read this email, I checked my company's Web-inf \Classes
directory, and found that we have been compiling in that directory, so the
directory has many .java files as well as .class files. Will this be
detrimental in any way? Should these .java classes be removed from
Web-inf\Classes and placed into a different directory?
Thank-you very much,
Donna
