Accessing a variable outside java code fragment in a jsp(Spring MVC)

Question

in my scenario i have a code like below:

     <c:forEach items="${dbEntries}" var="c" varStatus="loop">
                    <tr> 
                          <% 
                              int i = 0;
                              System.out.println(i);
                          %>
                          <td rowspan="1">${c.getRh_name()}</td>                                 
                          <td rowspan="1">${c.getIpm_name()}</td>` 
                    </tr>
      </c:forEach>

now i want to access the variable from html. like below

<h1>${i}</h1>

but its not displaying.can anyone help??

you can set i varilbe in request scope request.setAttribute("variableName",i) and access <h1>${variableName}</h1>. <h1> tag is out of the foreach or? — Gurkan Yesilyurt

@GurkanYesilyurt where will i declare this request.setAttribute("variableName",i) . I mean in <% %> ?? — Bidipta Dauka

yes, expressions (EL) like ${anything} works with scopes (request, session etc.). If you access any variable you can set it in any scope before. — Gurkan Yesilyurt

Use jstl instead of java code inside jsp like this.

    <c:set var="salary" scope="session" value="${2000*2}" /> 
     <c:out value="${salary}" /> 
    <c:forEach begin="1" end="5" step="1">
         <c:set var="salary" value="${2000*2}" /> 
    </c:forEach> <c:out value="${salary}" />
