sendRedirect() means it's client side redirect at that time
new parameters can be added.(i.e HttpRequest, HttpResponse)
forward() meand it's server side redirect at that time same
parameters can be used.
forward() can be used forwarding the request from one
servlet to jsp.(i.e with in the container).
redirect() can be used redirecting the one jsp to another
jsp(i.e different containers).
When we use forward, then servlet container forwards all
request to the target page. but in the case sendRedirect,
container makes a new request to the target Page.
So in forward , url link doesn't change but in sendRedirect
url line change . Because container makes a new request,
sendRedirect is much slower than forward.
If a target page has no relation with current
page , then we can use sendRedirect(I think so....)
forward() is a action element in jsp. it is used to pass
ctrl from current page to another jsp page and it is a
method in jsp.
send redirect() is a method in servlet.
there are two methods used. as
HttpServletResponse.encodeReDirctURL().which takes String
represents a redirction url.next sendredirect() method.
which takes the String returned from the
encoderedirectString() and send it back to the client for
redirection
forward mean forwarding the requset to some another jsp or
servlet this is done by server we have do describe the page
in the forward method's argument note thatforward method
argument accept only string ..
while sendredirect is on client side . the new request
object is created.
Both senredirect and forward metods are used to forward the
request to another resourse
but
1)the request dispatcher() is used when we want to redirect
the client requestto some other resourse (ie:out of context)
or whenver we want to redirect errors
where as
use forward()when we sending a page that is within in the
same site
2)forward() are executed on the serverside but send redirect
()are on the client side

1.forward will forward the request without saving the client
information where as sendRedirect will save the previous
information and send to another requested page.
2.The forward operation happens in the same request itself.
Once if you forward a request, you cannot add any more
response content after the forward command. Becuase, the
servlet ignores the remaining things and forwards the
request to another servlet.
The send redirect is the one, which redirects you to some
other servlet or page. The redirection is not within the
same request, but it is a new request. Using send redirect,
you can access a page available on another context / server.
I'll explain this with an example. If suppose u ask ur
servant(who is uneducated), to go to the market and get u a
Pepsodent.Now if the shopkeeper is not having a pepsodent
he will simply hand over Close Up to the servant.This
scenario is something simialr to the "forward" method. If
the requested resource is not available u will be
redirected to a different page whose url is specifiedd in
the forward method call. But u wont be able to see the
cnage in the url in the address bar. It's all done
internaly. In case os sendRedirect, its just like ur call
is moving from one page to another and u will able to see
the cnage in the url too. Its like normal page navigation.
Hope you would have a got a picture of it.
i developed a Stateless Session bean program.And created a
client by a common java class as
class m
{p s v m(String s[]){....}}
And i called the bean deployed in weblogic.from cmd prompt
And that run.
mind it i have to set setenv,seting classpath for that bean
jar file before compile and run it.
ok
when i do a servlet programme deployed in tomcat and call
that bean then it give classdefnotfoundException and
NoInitialContext like this.So how i sucessfully do this?
Ok
when i call that bean from java class from the console like
i previously told, if i don't set setenv i found the same
error on the cmd prompt.
pls help to get out of it
