You don't need another portlet -I believe the "proper" way to do what you
want is to use AJAX like you have been trying to do with option 2 but use
serveResource on your portlet to serve the AJAX calls. Assuming you
subclass GenericPortlet then the responsibilities are something like:
*doView:* Write the html framework of your portlet containing an empty div
where AJAX can put the content. You need to give that div a namespaced id
e.g.
String id = response.getNamespace()+"outer";
writer.println("<div id=\"" + id + "\">");
doView also needs to start the JavaScript. The JavaScript needs to be
given
the resourceURL (for the AJAX callbacks) and the id above (so it knows
which
piece of html to update). e.g.
writer.write("<script type=\"text/javascript\">");
ResourceURL url = response.createResourceURL();
writer.write("window.setInterval(function(){updateContent('" +
url.toString() +"','" + id + "');},5000,'JavaScript');");
writer.write("</script>");
*serveResource:* return the html or XML to provide the information your
javascript needs to update its window.
