Liferay ERROR [RuntimePageImpl-16] is not a valid include

Question

I'm struggling with the doView() method and initializing parameters from the portlet.xml. What I've been trying so far, is to just redirect to another view when I click a button, or a link. For that, I created two JSP:

view.jsp vista2.jsp

I define them in portlet.xml:

<portlet>
    <portlet-name>res-prot</portlet-name>
    <display-name>Res Prot</display-name>
    <portlet-class>com.test.ResProt</portlet-class>
    <init-param>
        <name>view-jsp</name>
        <value>html/resprot/view.jsp</value>
    </init-param>
    <init-param>
        <name>vista2-jsp</name>
        <value>/vista2.jsp</value>
    </init-param>   
    (...)

Then, I initialize them in the init() method:

String viewJSP;
String vista2JSP;

public void init() throws PortletException {
    viewJSP = getInitParameter("view-jsp");
    vista2JSP = getInitParameter("vista2-jsp");
}

Finally, I call to the doView() method, which calls the viewJSP if a parameter "navegacion" is empty:

@Override
    public void doView(RenderRequest renderRequest, RenderResponse renderResponse) throws IOException, PortletException {
        String destino = viewJSP;

        try {
            // we redirect only if "navegacion" is sent from the jsp
            if (renderRequest.getParameter("navegacion") != null){
                if(renderRequest.getParameter("navegacion").equalsIgnoreCase("vista2JSP")){
                    destino = vista2JSP;
                }
            }
            System.out.println("DESTINO: "+destino);
            include(destino, renderRequest, renderResponse);
        } catch (Exception e) {
            e.printStackTrace();

        }
    }

Then, in the vista2.jsp I just use a renderURL to do that call, but I don't even get there. I get this error and the portlet shows empty:

09:21:41,402 ERROR [RuntimePageImpl-16][MVCPortlet:357] html/resprot/view.jsp is not a valid include

This is how this dirty project is organized (remember that this is only for testing purposes):

What's failing here?

EDIT:

If I begin the route by "/", it throws a different error:

EDIT 2: If I move "view.jsp" to the root folder, keeps throwing the same error:

Answer 1

You should replace

<value>html/resprot/view.jsp</value>

By

<value>/html/resprot/view.jsp</value>
