best way to access the vector in jsp

[Gina Ferrara]

Hello all,
I like to know the best way to access a already populated vector in jsp.
I have servlet that talks to the backend beans and populate a vector

doGet() mehtod
{
….  
 Vector v = (Vector)getServletContext().getAttribute(“xmlvector”);
   request.setAttribute(“vector”,v);
   RequestDispatcher …...
   dispatcher.forward(request, response);
}

now in the jsp I have the following code

<%
Vector v = new Vector();
v = (Vector)request.getAttribute(“vector”);
XMLobject xmlobj = new XMLObject();
for (int i=0; i<v.size(); i++)
   xmlobj = (XMLObject)v.get(i);
  // do whatever you need to do with xmlobj
%>

So is this a best practice to access the object I have placed into the vector?
Is there a better way to do this?

Yes. You can use JSTL/EL. JSTL has a c:forEach tag for looping through a vector. EL lets you ${xmlObject.name} output properties of the loop element.

Just to make sure that there is no ambiguity, Jeanne's "yes" answer was to the question:

Is there a better way to do this?

Java code in scriptlets is an extremely poor practice that it almost 10 years out-of-date.
