Blank page when I add my portlet

Hi community,

I have a problem with a portlet I made for exo-ecm. I create a new page, added a new container in this page with the edit page button, and then I add my portlet in the container.
My portlet displays what I expect, but when I want to save the page, I get a blank page on Firefox or Internet Explorer...
Even if I want to go back in the history pages, I get a blank page until I am on the welcome page (when we are not connected).
So I don't understand what's happening, because I can see nothing on the tomcat console ...

Moreover, my "Map" button is not displayed in the portlet but in the container ...

My JSP page :

<html>
<%@ page language="java" %>
<%@ page contentType="text/html" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="html" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="core" %>
<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %>

<portlet:defineObjects/>
<core:view>
<head>
        <title>Map portlet</title>
</head>
<body>
<%
String userName = request.getRemoteUser();
if (userName.equals("exoadmin")) {%>
        Exoadmin :
        <html:form>
                <html:commandButton action="exoadmin" value="Map"/>
        </html:form>
<%} else {%>
        User
<%}
%>
</body>
</core:view>
</html>
