Good afternoon, I have a web application and I want to return data to a jsp, but when I log in, it does not show anything on the screen (blank screen) and I get the following error:

Ultimately he tells me this:

Thanks

I edit so I do not complicate it more than it is

<c:forEach items="${requestScope.listadoAnestesia}" var="anestesia">
                    <tr>
                        <td>${i}</td>
                        <td><fmt:formatDate type="date" value = "${anestesia.FecPrestacion}" /></td>
                        <td><c:out value="${anestesia.fecARA}" default="---"></c:out></td>
                        <td><c:out value="${anestesia.fecRendicion}" default="---"></c:out></td>
                        <td><c:out value="${anestesia.afiliado()}"></c:out></td>
                        <td><c:out value="${anestesia.nroAfiliado()}"></c:out></td>
                        <td><c:out value="${anestesia.osocial()}"></c:out></td>

The error is given to me in the first option I retrieve from the request

This is my class, it is a model from which I dump the data that I need to show so I do not complicate so much in the JSP, this data is added in the servlet that returns the data.

Correct use of Symfony models when complex Querys are needed Assign value to a date in angular 2 (binding)

score 1 · Accepted Answer

The error that is telling you is that anestesia is of type String , type that has no property or method " FecPrestacion ".

This seems to be happening because your listadoAnestesia does not contain a collection of your model ModeloAnestesia but of elements string ; the code you should share is how you generate that list.

EDIT

Additionally, viewing your model results in you having no property FecPrestacion but a private variable called fecPrestacion (with lower case at the beginning, Camell notation). This is that, in addition to not existing that property, the one that does exist is private so you can never access it from outside.

Try changing the code in the view so that you call the getters of your properties, like this:

<c:forEach items="${requestScope.listadoAnestesia}" var="anestesia">
    <tr>
        <td>${i}</td>
        <td><fmt:formatDate type="date" value = "${anestesia.getFecPrestacion()}" /></td>
        <td><c:out value="${anestesia.getFecARA()}" default="---"></c:out></td>
        <td><c:out value="${anestesia.getFecRendicion()}" default="---"></c:out></td>
        <td><c:out value="${anestesia.getAfiliado()}"></c:out></td>
        <td><c:out value="${anestesia.getNroAfiliado()}"></c:out></td>
        <td><c:out value="${anestesia.getOsocial()}"></c:out></td>
    </tr>
</c:forEach>

EDIT 2

According to this question , all you have to do is delete the " requestScope " on the label to the forEach (and ignore my edit previous):

<c:forEach items="${listadoAnestesia}" var="anestesia">
    <tr>
        <td>${i}</td>
        <td><fmt:formatDate type="date" value = "${anestesia.fecPrestacion}" /></td>
        <td><c:out value="${anestesia.fecARA}" default="---"></c:out></td>
        <td><c:out value="${anestesia.fecRendicion}" default="---"></c:out></td>
        <td><c:out value="${anestesia.afiliado}"></c:out></td>
        <td><c:out value="${anestesia.nroAfiliado}"></c:out></td>
        <td><c:out value="${anestesia.osocial}"></c:out></td>
    </tr>
</c:forEach>

but also consider that the attribute that you are defining in cargaAnestesista is "anesthesia" and in the jsp you iterate over "anesthesia list", you must use the same attribute name .
