But how do I get the Collection of object from the doView function
to the JSP page?
Here is an example of using JSP and portlet tags, also showing both
app and portlet session scoping as well:
------
the JSP view:
<%@ page session="true" contentType="text/html;charset=utf-8"%>
<%@ taglib uri='/WEB-INF/portlet.tld' prefix='portlet'%>
<%@ taglib uri="http://java.sun.com/jstl/core"; prefix='c' %>
<[EMAIL PROTECTED] file="/WEB-INF/view/include/portletDefineObjects.jsp" %>
<jsp:useBean id="appScoped" scope="session" class="java.lang.String" />
<jsp:useBean id="portltScoped" scope="request"
class="java.lang.String" />
<b>test</b>
<form method="POST" action="<portlet:actionURL/>">
<label for='portletScoped'>Portlet Scope Value:</label>
<input type="text" name="portletScoped" value='<c:out value="$
{portletScoped}"/>' size="20"/>
<input type="submit" value="Submit"/>
</form>
<form method="POST" action="<portlet:actionURL/>">
<label for='appScopedCount'>Application Scope Value:</label>
<input type="text" name="appScoped" value='<c:out value="$
{appScoped}"/>' size="20"/>
<input type="submit" value="Submit"/>
</form>

the java doView:
public void doView(RenderRequest request, RenderResponse response)
throws PortletException, IOException {
String portletScoped = (String)
request.getPortletSession().getAttribute("portletScoped",
PortletSession.PORTLET_SCOPE);
if (portletScoped == null)
portletScoped = "";
request.setAttribute("portletScoped", portletScoped);
super.doView(request, response);
}
--
the action:
public void processAction(ActionRequest request, ActionResponse
response) throws PortletException, IOException
{
PortletSession session = request.getPortletSession(true);
String appScoped = request.getParameter("appScoped");
if (!StringUtils.isEmpty(appScoped))
{
session.setAttribute("appScoped", appScoped,
PortletSession.APPLICATION_SCOPE);
}
String portletScoped = request.getParameter("portletScoped");
if (!StringUtils.isEmpty(portletScoped))
{
session.setAttribute("portletScoped", portletScoped,
PortletSession.PORTLET_SCOPE);
}
}
