Reset a scriplet variable on refresh

Question

I have a table and I want the lines to be numbered.

In my jsp, I have something like that:

<%! int i = 0; %> 
 <c:forEach items="${clients}" var="client">  
    <tr>  
       <td align="center"><%= ++i %></td>  
       <td><c:out value="${client.nomPrenom}"/></td>  
....

My problem is when I refresh the page, variable i is not reset to 0. It continues to ++

What do I do wrong?

You could do that using jstl as follows , as scriplets are not advised over decades

<c:forEach items="${clients}" var="client" varStatus="loop">  
    <tr>  
       <td align="center"><c:out value="${loop.index}" /></td>  
       <td><c:out value="${client.nomPrenom}"/></td>  
    </tr>
</ c:forEach>

see How to avoid Java code in JSP files? to learn more on using the jstl and EL

Your JSP is translated to servlet by server container. Every time you refresh your page _jspService is called.

Translation of JSP to servlet code :

public class HelloWorld2$jsp extends HttpJspBase {
        //code declare inside <%! %> method goes here
        public void _jspService(HttpServletRequest request,
                HttpServletResponse response)

        {
            // code declare inside <% %> method goes here

        }
    }

Instead of

<%! int i = 0; %>

Use Below Code:

 <% int i = 0; %>
