well only thing i can't understand here is how how is that you are sending a Vector from applet to servlet..

never mind as you have said you have collected a vector object in a servlet assuming that you redirect or forward that to the next JSP by storing that vector as an attribute in the scope of request/session/ServletContext(application)

public void doGet(req,res){

--

--

--

request.setAttribute("acquireVector",appletVector);

request.getRequestDispatcher("/someRandom.jsp").forward(req,res);

}

-

--

-

--

someRandom.jsp:

===============

-

--

-

--

<%

-

--

Vector vec = (Vector) request.getAttribute("acquireVector");

-

--

%>

if you want to know of how to do this using session you can take a look on your earlier post.

>am trying to save the vector in a session variable

how is that you are saving it under session ?

It be gr8 if you explain all this by presenting a your code snippets.

where someone out here can get a gud idea to fix your issue.

and to my knowledge the only conditions where a session variable in one JSP doesn't work

1). the session attribute is removed from session.

2). the existing session is unbound / invalidated / timed out and a new session is being created in a new JSP

now inorder to overcome those

1). make sure you remove that attribute from session appropraitely.

2).

case 1: say the session is still active at the container side and a new session is being created make use of jsessionid to bind the newly created session to the existing by which you can overcome this problem.

case 2:where a request object is destroyed and a session object bound is destoryed at the container please look into the cases where this is happening you have no other scope of doing this my last advice would be making use of servletContext / application scope (It is termed as one of worst practices too)

Hope that might help :)
