*/
public class Login extends MVCPortlet {
public void loginUser(ActionRequest actionRequest,
ActionResponse actionResponse) throws IOException, PortletException{
System.out.println("login action called");
String email = ParamUtil.getString(actionRequest, "emailId").trim();
String password = ParamUtil.getString(actionRequest, "password").trim();
ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY);
HttpServletRequest request = PortalUtil.getHttpServletRequest(actionRequest);
HttpServletResponse response = PortalUtil.getHttpServletResponse(actionResponse);
User userDetail = null;
try {
userDetail = UserLocalServiceUtil.fetchUserByEmailAddress(themeDisplay.getCompanyId(), email);
if(Validator.isNull(userDetail)){
actionRequest.setAttribute("EMAIL_NOT_EXIST", "Account not exist with email");
}else{
boolean passwordMatched = PasswordTrackerLocalServiceUtil.isSameAsCurrentPassword(userDetail.getUserId(), password);
if(!passwordMatched){
actionRequest.setAttribute("PASSWORD_NOT_MATCHED", "Please Enter Correct Password");
}else{
// if user exist with provide email and given password matched with user database password
ClassLoader pcl = PortalClassLoaderUtil.getClassLoader();
Class lClass = pcl.loadClass("com.liferay.portlet.login.util.LoginUtil");
java.lang.reflect.Method method = lClass.getDeclaredMethod("login", HttpServletRequest.class, HttpServletResponse.class, String.class, String.class, Boolean.TYPE, String.class);
method.invoke(null, request, response, email, password, false, CompanyConstants.AUTH_TYPE_EA);
//redirection after login...
String screenName = userDetail.getScreenName();
String portalURL = PortalUtil.getPortalURL(actionRequest);
if(PortalUtil.isOmniadmin(userDetail.getUserId()))
{
System.out.println("admin logged in, redirecting to admin specified private page");
actionResponse.sendRedirect(portalURL + "/user/"+ screenName+"/adminuser");
} else {
System.out.println("normal user logged in, redirecting to private page specified for normal user");
actionResponse.sendRedirect(portalURL + "/user/" + screenName +"/normaluser");
}
}
}
