I have a Spring application running that uses SpringMVC and EclipseLink.
This application works well with multiple top level domains at the same point, for example you can access:
http://www.foo.com/user/list
http://www.anotherdomain.com/user/list
http://www.company.com/user/list
But now I need to load a customized design for each domain, so I need to identify what is the domain that's accessing.
I'll need to implement a class that would set views path, etc.
Anyone knows a good solution for this?
Get it from Header "Host". In Spring
you can try #RequestHeader String host in controller method as parameter.
OR
get it from HttpServletRequest.getHeader("host")

I am working on SaaS application where I have implemented ASP.Net Web API as a service layer. In my Web API, when any request generated, it will have one header value "x-companyid" which is company specific and identify request comes from which company (Tenant).
I require that companyID in all my ApiControllers in Web API project. Of course I can get header value in every ApiController by using "Request.Headers.GetValues("x-companyid") but it will be repeated in all ApiControllers.
I have tried to create "BaseApiController" and inherit all my ApiControllers from "BaseApiController" but it's not allowing me to override ActionExecuting so that I can extract header at common place.
Can anyone suggest how can I extract "x-companyid" header commonly in my project so that I don't have to repeat code in all ApiController?
Your Best friend are action filters.
as they intercept each api call for specific controllers.
All u had to do is to decorate the controler name with something u made like
[Tenant]
public foo MyController()
{}
this approach gives you controll over what controllers you wish to add this extract to happen becouse maybe youll need some lookup apis and stuff that dont need to be for a specific Tenant
here is a very Helpful link :

Update
since there is a only one company for each instance
i would recommend adding a singleton for the current tenant u can access that anyway

I have a problem when calling web Services in ASP.net MVC , I do the following
add the web service by add service reference to solution, and I include the service.cs file to the solution also, but when I try to create object in home controller , I have the following error
Could not find default endpoint element that references contract 'Service' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.
can any one help me please
thanks
There's a couple things going on here. First, you're using SVCUTIL to generate a proxy and configuration settings for a non-WCF service - .asmx is legacy. I was able to generate a proxy and config settings, but to overcome the error you got you need to call one of the overloaded versions of WeatherHttpClient.
I'm not 100% sure, but this is what I think based on what I observed.
The reason is because there are two endpoints defined in the configuration file (one for SOAP 1.1 and one for SOAP 1.2), and since both endpoints are named there is no default endpoint to choose from.
When I used var x = new WeatherHttpClient(new BasicHttpBinding("WeatherSoap"), new EndpointAddress("http://wsf.cdyne.com/WeatherWS/Weather.asmx")); I was able to create the proxy just fine.
However, when I called GetCityForecastByZip I got the following error:
Server did not recognize the value of HTTP Header SOAPAction: http://ws.cdyne.com/WeatherWS/WeatherHttpGet/GetCityForecastByZIPRequest.
So then I used WSDL.exe to generate the proxy a la .ASMX style. I included that in my project, and the following code returned a result (after including a reference to System.Web.Services - I was using a console app):
var x = new Weather();
ForecastReturn result = x.GetCityForecastByZip("91504");`
I would suggest for simplicity using WSDL.exe to generate the proxy for your service, as it seems to be simpler.
I will also add that I've done very little MVC, but I don't think this is an MVC issue. I hope this helps you.
I've got an ASP .Net application running on IIS7. I'm using the current url that the site is running under to set some static properties on a class in my application. To do this, I'm getting the domain name using this (insde the class's static constructor):
var host = HttpContext.Current.Request.Url.Host;
And it works fine on my dev machine (windows XP / Cassini). However, when I deploy to IIS7, I get an exception: "Request is not available in this context".
I'm guessing this is because I'm using this code in the static constructor of an object, which is getting executed in IIS before any requests come in; and Cassini doesn't trigger the static constructor until a request happens. Now, I didn't originally like the idea of pulling the domain name from the Request for this very reason, but it was the only place I found it =)
So, does anyone know of another place that I can get the host domain name? I'm assuming that ASP .Net has got to be aware of it at some level independent of HttpRequests, I just don't know how to access it.
The reason that the domain is in the request is...that's what's being asked for. For example these are a few stackexchange sites from http://www.stackexchangesites.com/:
http://community.ecoanswers.com
http://www.appqanda.com
http://www.irosetta.com/
If you ping them, you'll see they all point to the same IP/Web Server and be served by the same app (or multiple apps in this case, but the example holds if it was one big one)...but the application doesn't know which one until a host header comes in with the request asking the server for that site. Each request may be to a different domain...so the application doesn't know it.
If however it doesn't change, you could store it as an appSetting in the web.config.
Use global.asax or write a HttpModule and subscribe to start request events. You will have the request passed into your event handler.
Use this instead:
HttpRuntime.AppDomainAppVirtualPath
Or if you want the physical path:
HttpRuntime.AppDomainAppPath

How would I generate a proper URL for an MVC application to be included in an e-mail?
This is for my registration system which is separate from my controller/action. Basically, I want to send an email verification to fire an Action on a Controller. I don't want to hardcode the URL in, I would want something like the Url property on the Views.
In your Controller, the UrlHelper is just called "Url" - so:
void Index() {
string s = this.Url.Action("Index", "Controller");
}
The "this" is unnecessary, but it tells you where this Url variable comes from
I used:
Html.BuildUrlFromExpression<AccountController>(c=>c.Confirm(Model.confirmedGUID.Value))
It is part of the HTMLHelper (I think in the MVC Futures) so you may have to pass an instance of the HTMLHelper to your service layer, not sure. I use this directly in my view which renders to an email. That gives you the absolute URL and then I store the domain (http://www.mysite.com) in the config file and append it before the URL.
You should probably make the URL part of the configuration of your application.
I know you can do stuff with e.g. the Server property on your web application, but the application will never know if its IP or domain name is reachable from the outside as it might be hidden behind a proxy or a load balancer.
If I'm reading the question correctly, you need to controller/action outside the MVC code. If so, you will need to simply configure the URL in Application Configuration or some such place, unless you have access to the controller classes and use reflection to get the names.
I've got a web service:
http://machine001/Services/conversionService.asmx
This web service has one method in it called convert(string pInput).
I am trying to find out if there is a way to figure out, without logging into machine001 and without actually calling the convert method, if this web service has security applied.
If I am able to reach http://machine001/Services/conversionService.asmx, see the service description, create the proxy class and instantiate the web service object from any client does that mean there is no security?
Use your browser and go to:
http://machine001/Services/conversionService.asmx?wsdl
And see if the description contains WSE Security declarations. And to you're last paragraph, yes if you can do all of that and you did not do anything else to authenticate, it is unsecured.
