I'm trying to merge large existing web app into sails.js. so I moved the folders into assets and build a custom route , 'GET /': '/assets/client/launch.html' and get 404 when I point my browser to http://localhost:1337/ as the / is correctly redirected to http://localhost:1337/assets/client/launch.html which produces the 404.
Now the file exists in the folder assets/client (and in .tmp), so I am thinking the Sails router is getting in the way.
I would leave the client (70K lines of JS) that generates all the UI dynamically and sailjs server that provides authentication separate and enable CORS but my customer wants client packaged with server. This type of operation is simple in frameworks like ASP.NET MVC but am wondering if Sails is up to the task.
Well, If everything you tried did not work out. There might be another solution ,
First of all since you are talking about sails app I am assuming other bundle must be sails as well ,
So here is what you do-
Change the port for another app that you want to attach to this.
Second whenever you want to go to page on another app simply redirect the client to another port ie
in html or esp put a href tag with different port.
<a href="localhost:PORT/route_to_file">
</a>
I got it working by placing my app into assets where we need to launch from assets/client/index.html as there would be too many dependencies to change. As I said above could not just add a route as Sails must getting in the way. However as in Chapter 3.2.2 of Sails in Action I generated a static asset npm install sails-generate-static --save. then I redirected to assets/client/index.html. As an aside that book is great and would highly recommend it.

So, I have a Spring-MVC RESTful backend, that is cross-domain enabled. It is unit-tested, I can call my web-services and get back the correct JSON.
I have a SmartGWT 5.1p and GWT 2.7.0 front-end application that works great in SuperDev mode or Classic Dev Mode, either works great. When I do this, I am using the old Firefox 24 browser with the GWT plugin, and I can see my app work just great. My datasources are tied to RESTful web-services, and I can create, retrieve, update, and delete records via my DataSources.
I can compile the whole app via Maven, and get a WAR created just fine. I tried moving this WAR over to a tomcat server, and it deploys correctly. I can see the app running in tomcat with no errors in the logs.
Then when I go to the first page, the app comes up s normal with no errors. The first thing I do is add a username and password into a form, and then it is supposed to call a LoginDataSource which is tied into a LoginCOntroller, or login web-service.
What I can see from firebug is that when I make my call, rather than just calling:
http://mydomain:8080/admin/login/user/myusername/pwd/mypassword
I get:
http://mydomain:8080/admin/login/user/myusername/pwd/mypassword?0{and a whole lotta stuff after this) ... the query string I presume.
When I hit the Submit button, I get a SERVER TRANSPORT error, and that's it, I don't get any more information that that. There is nothing else to report from firebug except that the OPTIONS and GET add a whole lot of query string nonsense after the password.
I can look in the tomcat logs, and I don't see any errors in there at all. I don't even see the URL call to the web-service.
Any help on this would be much appreciated. I've been dealing with SmartGWT for years, and switched to back-end development for a while, and not I am trying to make my SmartGWT front-end work as well. But, I am a little rusty as to what is happening now.
Thanks!
The problem is not the querystring, it's the old base url I have in the datasource. There is a method in each datasource called: getServiceRoot
In getServiceRoot, I was using a hardcoded "localhost:8080", which in client code that doesn't work. That means whoever is running the app in their browser, "localhost" means their machine. So, I had to change the getServiceRoot to do the following:
protected String getServiceRoot()
{
String baseUrl = "http://" + Window.Location.getHostName();
return baseUrl + UrlConstants.SOME_URL_REST_ENDPOINT;
}
Since I have two WAR's on the same machine;
one WAR is a Spring MVC back-end RESTful web-services
the other WAR is the front-end, SmartGWT client application
This is a problem I run into ... I think just because both are on the same machine, that to the front-end, just call the code on the localhost, because it is there. But to the browser, that could be any other machine.
I suppose I could have just hard-coded the public IP address of the machine running tomcat, and then the client-side SmartGWT would then certainly find the RESTful web-services. Or, I could have used a Spring Env Profile to make that happen as well. But the code change I made should work, provided both WARS are on the same machine.
I just got to remember that client-side code in a browser is relevant to the machine the browser is running on.
So, this is fixed. If anyone needs any clarification, please let me know.
very new at this. Could someone tell me what is the best method of submitting a form when using phonegap and JMQ? What I want to be able to do is passing the form data to a php file and then having the results passed back into app so that the user isnt directly accessing the php file at any point.
I found the following page link which basically does what I want but I keep getting "Origin null is not allowed by Access-Control-Allow-Origin" when testing out the code. So I'm guessing this will only work if the app is located on a server also?
Any happy would be great. thank <3
To test your solution on the computer you need to launch chrome from the terminal with the argument --disable-web-security. See this answer: Disable same origin policy in Chrome
In your Phonegap application you add a line of code to your config.xml in the www-folder: <access origin="*.yourdomain.com" />. Build, and you are now allowed to request all domains and subdomains from yourdomain.com. For more details on whitelisting see http://docs.phonegap.com/en/3.0.0/guide_appdev_whitelist_index.md.html#Domain%20Whitelist%20Guide
You are not able to make post through the local files, so Yes, you need to have it running in a Web Server.
But if you deploy your application, it should work either in a emulator or in your device.
So, this is a pretty trivial thing to accomplish apparently, but for some reason it just will not work for me. I created a VERY SIMPLE GWT app. It uses UIBinder just to display a label and a button, no actual processing or handling takes place. I did this to test deploying the app using strictly JS and html that is not hosted by Eclipse and Jetty or whatever.
I compile my app, run it in eclipse, and it works fine. However, when I try to run the html page directly from the WAR directory, it does not work.
Do I need this running on a webserver for it to work? It is just html and js, so I shouldn't? I've been to the GWT site about deploying, and surfed quite a few forums. They seem to always mention the necessity of a server, but it seems like it should not be necessary?
Since it is a pure JavaScript and HTML it should work properly without server. Checkout this link: Compile and run in Production Mode with Eclipse
In your EntryPoint class, in onModuleLoad() there's a RootPanel.get("someDivId") call somewhere. Make sure your html page (=the host page) contains a div with that id.
Also make sure your host page calls the right java script file. It's easy to forget to edit the host page after you renamed your GWT module (see rename-to in your .gwt.xml), as the generated JavaScript file matches your module name.
This will work locally on all browsers except Chrome for security reasons.

I have an application that started life as an MVC (1.0) app in Visual Studio 2008 Sp1 with a bunch of Silverlight 3 projects as part of the site. Nothing fancy at all. Using Ninject for dependency injection (first version 2 beta, now the released version 2 with the MVC extensions).
With the release of .Net 4.0, VS2010, MVC2 etc., we decided to move the application to the newest platform. The conversion wizard in VS2010 apparently took care of everything, with one exception - it didn't change references to mvc1 to now point to mvc2, so I had to do that manually. Of course, this makes me think about other MVC2 things that could be missing from my app, that would be there if I did File -> New Project... But that is not the focus of this question.
When I deploy this application to the IIS 7.5 server (running on Win2008 R2 x64), the application as such works. However, images, scripts and other static content doesn't seem to exist. Of course they are there on disk on the server, but they don't show up in the client web browser.
I am fairly new to IIS, so the only trick I knew is to try to open the web page in a browser on the server, as that could give me more information. And here, finally, we meet our enemy. If I try to go directly to the URL of one of the images (http://server/Content/someimage.jpg for instance), I get the following error in the browser:
The IControllerFactory 'Ninject.Web.Mvc.NinjectControllerFactory' did not return a controller for a controller named 'Content'.
Aha. The web server tries to feed this request to MVC, who with its' default routing setup assumes Content to be a controller, and fails.
How can I get it to treat Content/ and Scripts/ (among others) as non-controllers and just pass through the static content? This of course works with Cassini on my developer machine, but as soon as I deploy, this problem hits.
I am using the last version of Ninject MVC 2 where the IoC tool should pass missing controllers to the base controller factory, but this has apparently not helped. I have also tried to add ignore routes for Content etc., but this apparently has no effect either. I am not even sure I am addressing the problem on the right level.
Does anyone know where to look to get this app going? I have full control of the web server so I can more or less do whatever I want to it, as long as it starts working.
Thanks!
I had a similar problem with StructureMap and favorite.ico what I ended up doing was to add a route to ignore that path.
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("favicon.ico");
Keep in mind that I have absolutely no idea really but another thing that changed is the need for Default.aspx, also if you have any custom pages those would need to mapped. That's the only two problems I had with routing.
routes.RouteExistingFiles = false;
EDIT: I meant that the RouteExistingFiles should be false otherwise I get that exception in MVC2 :)
Turns out this was caused by some account settings - I was unaware of the IIS AppPool\sitename account automatically being created by IIS in Win2008 R2 server. After trying "everything", I came across this information, gave the proper rights, and stuff magically started working.
Pretty hard thing to debug, especially for someone (me) with very limited IIS experience.
I want to use the #! token to make my GWT application crawlable, as described here:
http://code.google.com/web/ajaxcrawling/
There is a GWT sample app available online that uses this, for example:
http://gwt.google.com/samples/Showcase/Showcase.html#!CwRadioButton
Will serve the following static webpage to the googlebot:
http://gwt.google.com/samples/Showcase/Showcase.html?_escaped_fragment_=CwRadioButton
I want my GWT app to do something similar. In short, I'd like to serve a different flavor of the page whenever the _escaped_fragment_ parameter is found in the URL.
What should I modify in order for the server to serve something else (a static page, or a page dynamically generated through a headless browser like HTML Unit)? I'm guessing it could be the web.xml file, but I'm not sure.
(Note: I thought of checking the Showcase app provided with the GWT SDK, but unfortunately it doesn't seem to support serving static files on _escaped_fragment_ and it doesn't use the #! token..)
If you want to use web.xml, then I think it won't work with a servlet-mapping, because the url-patterns ignore the get parameters. (Not 100% sure, if there is another way to make this possible.)
You could of course map Showcase.html to a servlet, and in that servlet decide what to do, based on the get parameter "_escaped_fragment_". But it's a little bit expensive to call a Servlet just to serve a static page for the majority of the requests (not too bad, but still. You could set cache headers, if you're sure that it doesn't change).
Or you could have an Apache or something in front of your server - but I understand, I wouldn't like to have to do that either. Maybe your JavaEE server (which one are you using BTW?) provides some mechanism for URL filtering before the request gets passed on to the web container - I'd like to know that, too!
Found my answer! The Showcase sample supporting crawlable hyperlinks is in the following branch:
http://code.google.com/p/google-web-toolkit/source/browse/branches/crawlability/samples/showcase/?r=7726
It defines a filter in the web.xml to redirect URLs with the _escaped_fragment_ token to the output of HTML Unit.
