How can I evaluate the content of an expression language variable in the Eclipse debugger?

I am using Eclipse and I have the following problem debbugging a JSP page.

So into a JSP page I have something like this:

<c:forEach items="${listaScuoleDS}" var="scuola" varStatus="item">
    ................................................
    ................................................
    DO SOMETHING
    ................................................
    ................................................
</c:forEach>

So, as you can seem in the forEach cycle I am using the expresion language that identify a collection on which iterate: items="${listaScuoleDS}"

Now, starting the application in debug mode and putting a brackpoint on the previous <c:forEach ....> statment, the application correctly stop on this line but I can't analyze the content of the "${listaScuoleDS}" variable.

I try to put "${listaScuoleDS}" into the Ecipse expression debug tab but I obtain no value.

How can I see the content of the previous EL variable in debug mode?

There's an implicit object called pageContext. You should be able to access this variable through your debugger. I have noticed that this method may not work in IntelliJ but it does work in Eclipse.

In Eclipse: Open Debug Perspective and write 'pageContext' in the Expressions window.

Here are a couple reference:

Unfortunately you can not debug tags bound to taglibs inside JSP-Files.
