getProperty not accessing correct object

[Dave Hathaway]

I am trying to use an object with getProperty, the object is created within a scriplet. I am not getting the object created in the scriplet - can anyone please let me know why?
here is the Server Page
<%@ page import="CounterBean" %>
<jsp:useBean id="counter" class="CounterBean" >
<% counter = new CounterBean();
counter.setCount(44);
System.out.println("counter count:" + counter.getCount());%>
</jsp:useBean>
<h3>
the count should be 44 but is?
<jsp:getProperty name="counter" property="count" />
</h3>
and here is my CounterBean
public class CounterBean
{
private int count;
public int getCount()
{
return count;
}

public void setCount(int count)
{
this.count=count;
}
}
When running the JSP I get the following output
the count should be 44 but is? 0
I expect the count to be 44.

<jsp:useBean id="counter" class="CounterBean" >
By using the "useBean" tag you are already doing something like this:
CounterBean counter = new CounterBean();
when it jsp is invoked for the first time(Later on , the same object may be used, depending on the scope setting).
So there is no need to initialise counter object again!
Remove the line counter = new CounterBean() from the scriptlet, and it should give the desired functionality.

Sowmya - thanks for the reply.
This will work but doesn't answer the question why can't I change the object reference of counter?
Sometimes I made need to change the object reference - if I wanted to say receive a counter from a vector of counters (list) which had been set by a servlet (setAttribute("list",list) - how I could I access this with getProperty.
I am getting the same problem having changed the object reference.
In this case...
<%@ page import="CounterBean" %>
<jsp:useBean id="counter" class="CounterBean" / >
<%
Vector v = (Vector)request.getAttribute("list");
Iterator i = v.iterator();
while (i.hasNext()){
counter = (CounterBean)i.next();
counter.setCount(44);
<h3>
the count should be 44 but is?
<jsp:getProperty name="counter" property="count" />
</h3>
<% } %>

Look at the Java source code that is generated. JSP is doing a lot of stuff you dont see.

I finally worked it out - to make the object visible to the bean setAttribute afterwards.
For Example:
<%@ page import="CounterBean" %>
<jsp:useBean id="counter" class="CounterBean" scope ="request" >
<% counter = new CounterBean();
counter.setCount(44);
request.setAttribute("counter",counter); %>
<h3>
the count should be 44 but is?
<jsp:getProperty name="counter" property="count" />
</h3>
</jsp:useBean>
