Subject: Re: Some JSP Questions..
I have some questions in JSP. Could any one one has answers for these
questions..
1. Difference between Include and Forward tags.?
action :
<%@ include file = filename>
Include action is used to include resources at runtime. The file
included is parsed at translation time.
Most jsp containers keep track of included file and recompile if it
changes.
if you change the included file then you need to recompile the
includer file also to get the result on the page.
directive
<jsp:include page=pagename flush = true/false />
you can use this if your resource is not going to change
frequently
<jsp:forward>
teh resource to which you are forwarding should also have the same
jsp context
execution in the current jsp page is stopped when it encounters
this tag , buffer is cleared
if output stream is not buffered then IllegalStateException is
thrown
2. Difference between Class and beanName in UseBean tag.?
class is the name of the class name fully qualified
beanName - name as you would suypply to instantiate() method in
java.bean.Beans class
you can have type and bean Name and omit class
attribute
eg: <jsp:useBean id="languageBean" class="LanguageBean"
scope="Page">
you should have a class called
public Class LanguageBean{}
id is basicaly to refer this bean in the page
3. Does a bean has to be put in a package to be used from a JSP page.?
need not be always but as such java language prefers to have a
class in a package
package serves like the directory service in JNDI.
hope this helps

Ramesh Kesavanarayanan
