in java spring mvc web app, want pass request parameter in link. following portion of .jsp page code `
<c:url var = "updatelink" value="/customer/showformforupdate"> <c:param name="customerid" value="${tempcustomer.id}"></c:param> </c:url> <c:foreach var="tempcustomer" items="${customers}"> <tr> <td> ${tempcustomer.firstname} </td> <td> ${tempcustomer.lastname} </td> <td> ${tempcustomer.email} </td> <td> ${tempcustomer.id} </td> <td> <a href="${updatelink}">update</a> </td> the portion of code below works fine..it displays customer id 'tempcustomer'.
<td> ${tempcustomer.id} </td> however,
<c:url var = "updatelink" value="/customer/showformforupdate"> <c:param name="customerid" value="${tempcustomer.id}"></c:param> this portion of code doesnt work fine. value="${tempcustomer.id}" doesn't pass value of tempcustomer.id. when click, update link
<td> <a href="${updatelink}">update</a> </td> the url looks
http://localhost:8080/web-customer-tracker/customer/showformforupdate?customerid=
