Is it possible to somehow override the login method of the Secure.java class of the Secure-Module in Play! Framework, so that another version of the login form is displayed?
In my case, i want to display a mobile version of the login-form if a mobile browser is detected.
I know i should not change the Secure.java class itself, but i don't really see any other solution to this problem.
As discussed in other posts you have the request in your Play! controller. So in this request you could ask which agent is trying to view your website:
String agentInfo = request.headers.get("user-agent");
The you can determine which template will be rendered for this agent:
if (agentType.isWhatEverHeIs) {
renderTemplate("Application\mobileTemplateForBadPractise.html");
} else {
render();
}
But what I would encourage you to do is responsive webdevelopment. Create your templates as smart as possible, let the template and css and javascript do this and keep your business logic in your controller.
You could use the Twitter Bootstrap to achieve this, but there are many more! Like Skeleton.
You even got the request object inside your templates so that you can optionally render things in your template (or not) based on the agent.
Even simpler, simply create/override the secure/login.html template and use responsive design : media queries. No need to change the controller or check agent or whatever.

So I'm working on implementing Oath2 authentication to allow my app to access Intuit Quickbooks company resources (items, customers, etc).
Intuit provides working examples using Spring, but I'm developing my app using JavaEE 8 with GlassFish5.
The Spring sample app callback contoller is structured as follows:
#Controller
public class CallbackController {
...
#RequestMapping("/oauth2redirect")
public String callBackFromOAuth(#RequestParam("code") String authCode, #RequestParam("state") String state, #RequestParam(value = "realmId", required = false) String realmId, HttpSession session) {
...
//after successful validation
return "connected";
This is the redirect handler controller; which address it's configured at the intuit portal (in this case, http://localhost:8080/oauth2redirect) that will be called after user approves the app and intuit will send back authorization code to this url.
So I'm a bit stuck finding what's the equivalent Spring callback redirect handler in JavaEE.
Is a #WebServlet or #WebService needed here? But then it wouldn't integrate nicely with JSF to just return the "connected" string so that it redirects to desired page (in this case connected.xhtml).
Not looking for workarounds, but the correct and standard way of implementing this on JavaEE. If you can point me to some sample apps out there or tutorials I would greatly appreciate it.
Thanks a lot in advance!
Here's full source code for callback handler controller and the full sample app.
There is at least not a really good alternative in JSF. Yes, you could 'abuse' JSF but there are other, better standards for this and this is (almost) what Spring also does. If you read the Spring Specs , you'll see the word 'Rest' being used a lot.
Well, there is a real java standard called 'Jax-RS' that is the standardized counterpart of what you do in spring.
This provides a decent analysis of the two So Jax-RS is the way to go.
But a #WebServlet or #WebService integrate perfectly with JSF. You can store any authentication information in the session and use that from JSF. No problem at all.
Can anyone share some detailed info on how to create a Single Page Application (SPA) in Liferay 7 using SennaJS.
I could't found any documentation on How to create SPA in Liferay 7.
It comes by default, except if you unset the following property:
javascript.single.page.application.enabled=true
BTW, it is rather annoying in dev instances, as it takes a while to load pages in the first access, sometimes you even need to reload the page. Also, be aware, in some especial cases, some applications might break, normally due to code that counts with page reloads to function properly.
you can even create it in 6.2 by using the following code.
// initializing senna
var app = new senna.App();
// Set links selector for navigations
app.setLinkSelector(".senna-link");
// set basic path of liferay site
app.setBasePath('/web/spa-demo/');
// Id of DOM element which will be replaced from
// next page request
// using content div - default in liferay theme
app.addSurfaces('content');
// define routes for all the navigation links
// route link = Base path + page link
app.addRoutes([
new senna.Route('home', senna.HtmlScreen),
new senna.Route('second', senna.HtmlScreen),
new senna.Route('third', senna.HtmlScreen),
]);
Thing which you need to take care of, if it is SPA, then all the events need to be bound first i.e. delegate as there is not going to be page refresh.
i.e things like document.getReady is only going to be called once.
Whatever the portlet you are going to create and deploy with Liferay SDK/Workspace OR any compatible liferay plugin it will be SPA by default.
No need to do any coding on top of it.
I created a new Web API project and created the following routing spec (actually I have simplified, looking for the bug):
// Web API configuration and services
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}"
);
When I make a call via ajax with the route:
/api/account/GetSUID/0
everything works fine. When I just use a different controller:
/api/tile/GetTileSet/0
it returns a status of 200 but instead of hitting my controller, it just returns the contents of the default page in jqXHR.responseText! It is as if it is just skipping any API routing like I am requesting the default site page.
I am baffled by this one as I have written literally hundreds of web API functions over the past few years in several other projects. I have never had any issue making calls to multiple controllers. I have looked high and low for what could be happening here and am hoping that someone here might have an idea.
Here is a sample method on the controller:
[HttpGet]
public HttpResponseMessage CheckRequestedID(int id, [FromUri]string Search)
{
if (!BSDIUtil.HasAllAcceptableCharacters(Search))
return Request.CreateResponse(HttpStatusCode.BadRequest);
if (FolderModel.IDAlreadyExists(DAL, Search)) // We can check this because this function is only called when staff members are creating accounts for other people (participants always use their email).
return Request.CreateResponse(HttpStatusCode.OK, false);
else
return Request.CreateResponse(HttpStatusCode.OK, true);
}
This will work if on the account controller but not on the tile controller.
One other thing, I am using the "Community" edition of Visual Studio and Windows 8.1
This is not a problem that is likely to occur often but I have solved it and figured I would post it here in case anyone else has the same issue.
I am using web api in the context of a standard web forms app (although I am only using webforms for my reporting pages). In the web.config for a web forms app, you can declare the paths that the user has access to before authenticating. I was only providing access to the account controller: all others were not permitted due to my authentication mechanism. Once I authenticate (e.g. the forms authentication call) or if I change the location path to include only "api", the problem goes away.
I was facing same problem but in different context. Had many controllers and respective routing templates. Only one controller was responding to requests.
Later i realized my other controller classes were not public!!
I am using Mvvmcross crosscore in my project
I am trying to bind my loginviewmodel to the loginviewcontroller
I bound a command for the login button. the app waits until it gets a login response, which is stored in the loginViewModel itself..
How can I communicate this to the loginviewcontroller --- regarding the login status and login error message if any
Can I access the viewmodel datacontext inside my loginviewcontroller ??? and how ?
What is the best approach to communication any items in the viewmodel back ( I basically mean all the NON-UI binding items)
I am using Mvvmcross crosscore in my project
I'm assuming from this that you followed the CrossLight sample N=39.
Can I access the viewmodel datacontext inside my loginviewcontroller ??? and how ?
If you followed N=39. then you can access the DataContext using the property called DataContext - see https://github.com/MvvmCross/NPlus1DaysOfMvvmCross/blob/master/N-39-CrossLight-Touch/CrossLightTouch/MyViewController.cs#L33
public object DataContext
{
get { return BindingContext.DataContext; }
set { BindingContext.DataContext = value; }
}
Beyond this, there are many other examples in the N+1 videos which demonstrate how to communicate between ViewModels and Views including error messages and loading dialogs - e.g. N=34 shows one implementation of progress dialogs - https://github.com/MvvmCross/NPlus1DaysOfMvvmCross/tree/master/N-34-Progress
A complete index of N+1 videos is available on http://mvvmcross.wordpress.com
Obviously not all of these are appropriate for your CrossLight approach to development, but this is where you can allow your custom mvvm approach to fill the gap - it's code for you to write in your custom framework.
One of the best methods solving viewmodel interdependencies is using a loosely coupled approch using the MessageBus/Event Aggregator pattern. There's a plugin for MvvmCross. Or you could use the excellent TinyMessenger.
In principle when using this approach, you no longer establish hard references between the publisher and consumers of arbitrary notifications. Instead notifications get published on a message bus and every one is free to listen and subscribe.
I'm looking at Mixu's Auth module for Kohana 3.1 but want to implement the UI into my own site templates. At the moment my site runs properly using its own template until it gets to a restricted page. At that point it loads the useradmin module's template for logins. I'd like to just load the page components into my own template and navigation.
What is the best way to go about this please? I had imagined I would be able to arrest the flow at some point within my 'application' environment without editing the 'module' environment.
EDIT:
I'm a little further along now. I've created two Controller classes:
application/classes/controller/app.php
application/classes/controller/user.php
Each extends the module class and replaces the template reference. Eg:
<?php defined('SYSPATH') or die('No direct access allowed.');
class Controller_User extends Useradmin_Controller_User {
public $template = 'smarty:maintemplate';
}
I guess this is the right approach. I'm using Smarty Templates which is compounding the issues as I need to merge different templates. I'll keep plugging away and see how I go.
I don't know about the best way, but I had a similar situation.
In the end, I copied part of the code from the module that I needed, and rolled my own implementation of the module.
Btw. Smarty is ok, but Kostache (Mustache for Kohana) rocks. More flexible and you can use the same templates for php and javascript.
