you must understand java classpath means.

classpath is the key of your question.if you understand it,you can get answer by yourself.

check your system variable and make sure your classpath is right.

myeclipse 5.5GA

in redirect, lost original request

in forward ,keep original request.

just so so

public interface A{ public void a(); public void b(); public void c(); ......very very much method()...... }

when we wan`t use one method() of interface A like c(),but i don't want implment all method().

so you need a adapter to implment all method of interface A,the method in adapter do nothing like public void a(){} public void b(){} public void c(){} ......

when we have one adapter ,you can extend it and overriding thr method which you wan`t use.

please google adapter

You should understand MVC .

please use jsp as the view only,why do you wan`t insert java code in you jsp?

why not use jstl?why not use tag?

you`d better don`t type method in your jsp.

MVC MODEL1 jsp+javabean

use the jsp as both the Controller and the view.

model2 jsp+servlet+javabean

use jsp as the view only

use servletas the Controller only

why not use connection pool?
