Another question: in Jason Hunter's book, jsp stuff looks different from the
JSP tutorial
from java.sun.com. Hunter uses <bean></bean>, and the tutorial uses
<jsp:useBean>
instead. Any difference?
About the <servlet> tag, the reason I want to use it is: i want to refresh
my page every
5 minutes automatically. when I add some other jsp stuff like <%@....%> in
my page,
it cannot be refreshed automatically. And the Preston suggested me to use
<servlet>
tag instead. Do you have some other way to achieve that?
Thanks
Liwen
