c:forEach not iterating over object fields
Tried this way too and it prints the employee object (not printing first name, last name and city values ).
<c:forEach var="object" items="${employeeList}"> <tr> <c:forEach var="field" items="${object['class'].declaredFields}"> <td><c:out value="${object[field.name]}"/></td> </c:forEach> </tr> </c:forEach>

JSP
c:forEach not iterating over object fields
employee list has List of Employee. Inner forEach loop is not printing the employee first name, employee last name and city in each iteration.
<c:forEach var="employee" items="${employeeList}"> <tr> <c:forEach var="result" items="${employee}"> [b] <td><c:out value="${result}"/></td>[/b] </c:forEach> </tr> </c:forEach>
public class Employee { private String firstName; private String lastName; private String city; public String getFirstName() { return firstName; } public String setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public String setLastName(String lastName) { this.lastName = lastName; } public String getCity() { return lastName; } public String setCity(String city) { this.city = city; } }
