Problem Trying to minimize userlogin portlet

Question

Hi,
I have a UserLogin portlet which is working, but I would like to have minimized initially. My index.jsp is shown below, where I have tried to use PortletBackingContext to do the minimize, but I am getting an error which seems to be occurring when I try to access the context:
Errors found in C:\bea\user_projects\applications\myjlportal\app\portlets\userLogin\index.jsp:
Error at line 63 column 34:
Description: No variable, field, type, or package with this name could be found at this location.
Warning at line 67 column 23:
Description: This file does not exist.
Found 1 error(s) and 1 warning(s).
Can anyone tell me what the problem is?
Perhaps using a backing context is not the right way to go about doing this. If so, can anyone tell me how I might do it?
Thanks,
Jim

hi,
to change page, change status of a portlet use backingfiles like this one:
public boolean preRender(HttpServletRequest request, HttpServletResponse response) {
//log("preRender called");
PostbackURL url = PostbackURL.createPostbackURL(request, response);
HttpSession session = request.getSession();
String portletName = (String) session.getAttribute(PORTLET_NAME_PARAM);
String pageName = (String) session.getAttribute(PAGE_NAME_PARAM);
if (pageName != null) {
session.removeAttribute(PAGE_NAME_PARAM);
url.removeParameter(GenericURL.PAGE_LABEL_PARAM);
url.addParameter(GenericURL.PAGE_LABEL_PARAM, (String)pages.get(pageName));
if (portletName != null) {
session.removeAttribute(PORTLET_NAME_PARAM);
//url.removeParameter(GenericURL.PAGE_LABEL_PARAM);
url.addParameter(GenericURL.WINDOW_LABEL_PARAM, portletName);
if (session.getAttribute(MAXIMIZE_METHOD) != null) {
log("maximize portlet: " + portletName + " and change page to: " + (String)pages.get(pageName));
session.removeAttribute(MAXIMIZE_METHOD);
//url.addParameter(GenericURL.PAGE_LABEL_PARAM, LOGIN_PAGE_LABEL);
url.addParameter(GenericURL.STATE_PARAM, "maximized");
} else {
log("normalize portlet: " + portletName + " and change page to: " + (String)pages.get(pageName));
session.removeAttribute(NORMAL_METHOD);
url.addParameter(GenericURL.STATE_PARAM, "normal");
//url.addParameter(GenericURL.PAGE_LABEL_PARAM, FIRST_PAGE_LABEL);
try {
response.sendRedirect(url.toString());
} catch (Exception e) {
e.printStackTrace();
return true;
hope this helps
ciao
