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

SV: Some JSP Questions..
Hi!
@include includes the file when jsp is compiled
This means that the source of the included page is parsed into the including
page when the page gets compiled. All variables and objects instantiated in
either page are accessible on both pages.
jsp:include includes the file at runtime
The page is included dynamicly when a request is made. The different pages
share request, response and session with the other but objects and variables
instantiated on either page can't be accessed by the other.

Mathias

Re: Some JSP Questions..
Good questions to help me study for the SCWCD exam...
Answers (from the JSP 1.2 specs)
1. Difference between Include and Forward tags.?
A A jsp:forward effectively terminates the execution of the current page. while a
jsp:include.../ element providers for the inclusion of static and dynamic resources
in the same context as the current page.
2. Difference between Class and beanName in UseBean tag.?
I do not understand this and it doesn't really answer your question but here are the
definitions (If anyone really understands the difference please help out)
class - The fully qualified name of the class that defines the implementation of the
object. The class name is case sensitive.
beanName - The name of a Bean, as expected by the instantiate() method of the
java.beans.Beans class. This attribute can accept a request-time attribute expression
as a value.
3. My opinion is no but I could not find any information on this in the specs. Anyone
else?

Re: Some JSP Questions..
The difference between Class and beanName is a subtle one and it's not used
much.
It's where you want polymorphism.
beanName=Secretary Class=Employee
is more or less equivalent to a statement like
Employee x = new Secretary();

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
Regards
Ramesh Kesavanarayanan
