2. Must I place all my class files in the WEB-INF
folder and all JSP's outside?
A1:
The class files should place into WEB-INF/classes
folder and the JSP files should place within a
separate folder.
A2:
Yes! Otherwise the web server/ application server
cannot access the .jsp files and classes.
The java class files can be placed either in
WEB-INF/lib or WEB-INF/classes. But it is recommended
to put the class files in WEB-INF/classes. The server will

A4:
Class files inside web-inf cannot be access by

A6:
1. Class files - Either they must be in
