I do not know why is this happening, cause Authentication works, except for that ugly exception that I think is thrown after trying to render the content presenter portlets
Some of the content presenter portlets work(I mean i can see it's content and can be modified)fine but the ones recently added don't Does anybody knows the reason???
It does not work even when i start a new project.

Answer 1

I'm using the sample at wlp docs
package login;
import com.bea.netuix.servlets.controls.content.JspContentContext;
import com.bea.netuix.servlets.controls.content.backing.AbstractJspBacking;
import com.bea.p13n.security.Authentication;
import com.bea.portlet.GenericURL;
import com.bea.portlet.PostbackURL;
import javax.security.auth.login.LoginException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class LoginBacking extends AbstractJspBacking {
private static final long serialVersionUID = 1L;
public static final String REDIRECT_ACTION = "redirect";
public boolean handlePostbackData(HttpServletRequest request, HttpServletResponse response) {
if (isRequestTargeted(request)) {
if (request.getParameter(GenericURL.STATE_PARAM) == null) {
String username = request.getParameter("username");
String password = request.getParameter("password");
PostbackURL url = PostbackURL.createPostbackURL(request, response);
if (username != null && password != null) {
try {
Authentication.login(username, password, request, response);
catch (LoginException le) {
request.setAttribute("loginErrorMessage3", new String("true"));
return false;
else if (request.getParameter("logout") != null) {
Authentication.logout(request);
url.addParameter(GenericURL.LOADSTATE_PARAM, "false");
url.addParameter(GenericURL.PAGE_LABEL_PARAM, "login");
try {
JspContentContext jspContext = JspContentContext.getJspContentContext(request);
jspContext.sendRedirect(url.toString());
catch (Exception ie) {
ie.printStackTrace();
return true;
In fact the problem is at the line that executes redirection ... jspContext.sendRedirect(url.toString());
