Get value of an attribute of an object and put it in a variable in jsp

  • 772

I need to get the value of an attribute of an object (user.state) and put it inside a JSP variable (state) to then make if statements depending on that variable. Here the code.

<tbody>
                <tr>
                    <td><c:out value="${usuario.id}"/></td>
                    <td><c:out value="${usuario.apellidos}"/></td>
                    <td><c:out value="${usuario.nombre}"/></td>
                    <td><c:out value="${usuario.usuario}"/></td>
                    <td><c:out value="${usuario.clave}"/></td>
                    <td><c:out value="${usuario.permisos}"/></td>
                    <td><c:out value="${usuario.estado}"/></td>
                    <% String estado=(AQUI ES DONDE NECESITO OBTENER EL VALOR DE usuario.estado);%>
                    <td><form action=""><button type="button" class="btn 
btn-block btn-info btn-xs" name="${usuario.usuario }" value="${usuario.usuario }">Editar</button></form></td>
                    <td><form action="DeshabilitaServlet" method="post">

    I already found a solution and it is using JSTL itself

    <tbody><tr>
              <c:forEach var="usuario" items="${listarUsuario}">

                <tbody>
                <tr>
                    <!-- <td><c:out value="${usuario.id}"/></td> -->
                    <td><c:out value="${usuario.apellido_p}"/></td>
                    <td><c:out value="${usuario.apellido_m}"/></td>
                    <td><c:out value="${usuario.nombre}"/></td>
                    <td><c:out value="${usuario.usuario}"/></td>
                    <td><c:out value="${usuario.clave}"/></td>
                    <td><c:out value="${usuario.permisos}"/></td>
                    <td><c:out value="${usuario.estado}"/></td>
                    <td><form action="editaServlet"><button type="button" class="btn btn-block btn-info btn-xs" name="ediusario" value="${usuario.usuario }">Editar</button></form></td>
                    <c:choose>
                        <c:when test="${usuario.estado=='1'}">
                                <td><form action="DeshabilitaServlet" method="post"><button type="submit" class="btn btn-block btn-success btn-xs" name="usu" value="${usuario.usuario }">Activado</button></form></td>  
                        </c:when>
                        <c:when test="${usuario.estado=='0'}">
                                <td><form action="DeshabilitaServlet" method="post"><button type="submit" class="btn btn-block btn-warning btn-xs"  name="usu" value="${usuario.usuario }">Desactivado</button></form></td>  
                        </c:when>     
                    </c:choose>

                    <td><form action="EliminarServlet" method="post"> <button type="submit" class="btn btn-block btn-danger btn-xs" name="elimusuario" value="${usuario.usuario }">Eliminar</button></form></td>




                    <!-- <td><a href="<s:url action="edit"><s:param name="user.id"><c:out value="${user.id}"/></s:param></s:url>" class="btn btn-primary btn-xs">Editar</a></td>
                    <td><a href="delete.action?user.id=<c:out value="${user.id}"/>"><button class="btn btn-danger btn-xs">Delete</button></a></td>  -->

                </tr>
                </tbody>
                </c:forEach>
          </tbody>

    With the and apart from being able to use them as an if , they can use the variables that the servlet sends, in this case capture user.state and depending on whether it is 1 or 0 execute an action
