I've created a web application that runs a web service (WCF). The source code is long gone but I just checked that the app itself is still up and running. Given that I have the address to the service (something.azurewebsites.com) and the name of one of the methods exposed (parameterless Ping), how can I learn the location of the WSDL file?
As far I recall, I've exposed it the most common way, the publish file fetched from the suggestion on Azure portal. I'd like to just call the method Ping to verify something, so rebuilding a whole new service seems a bit overkill.
Suggestions on what the exact URL might be? Alternatively, suggestions on a tool to sniff that up?
Go to the Azure portal and find the FTP address for your "something.azurewebsite.net". Then use an FTP program to connect to the server and browse the files. This way you might be able to find the ".svc" file. For that matter, you might be able to download all of your code and use a tool like Reflector to view the .Net compiled code.

I would like to open PDF file inside my Django application, something like
file:///...
I know that a lot of posts state that this should not be done because security reason, and that google block this calls with error. link.
But, I know that:
I saw this behaviour so, I know it can be done somehow
I don't have security risk, because application is internal, not connected to the internet (available over lan)
Protocol file:/// wouldn't exist if there wouldn't be a way to use it.
I also read somewhere that you need to put file in 'public' if you would like to access it via this method. Do anyone know how to do this?
file:// is only available for browsers, not servers.
If you want your Django application to access local files, you need to upload them to the Django application server (at which point they're not really local).
(If the application server is running on the same machine as the client, naturally you can use Python's usual file functions to read the local file system.)
JavaScript can also access local files and process them in-browser as long as they're manually selected by the user.
I am trying to import a WSDL in to my Domino Designer 9.0.1 client. I have downloaded the WSDL file and specify it in the Local File part of the wizard.
I click OK and get the error
"The requested operation failed. Server redirected too many times (20)"
I have imported other WSDL's without a problem and the only difference with the one I now need, is that I need to login to see the WSDL.
Does this stop the wizard?
If so, is the only option writing the java agent from scratch to access the data?
Obviously I cannot provide the actual wsdl I am trying to attach to as it is a paid service, so not sure what other information I can provide to help find a solution.
Thanks

I want my customers to upload some file to my server. My current design is as below:
I make a folder on my server with R/W permission to Anonymous user like this: http://myserver/uploads
Customer contact my web service to indicate they want to upload something, and the webservice returned a path like this: http://myserver/uploads/xxx-xxx-xxx-xxx, the xxx part is a GUID.
But I don't know what to do next? I believe customer has the permission to write to the virtual path returned by the web service, but how could I write my client-side code so that it can actually copy things to that virtual path? My client-side is a Win32 application, not a web page.
What if I want the customer upload files within a web page, how to do that? I know that there's a "PUT" method in HTTP protocol that could be used to upload things to server, but how to use that?
I am new to this kind of web development. I hope I made myself clear. If there's any better design, please let me know.
Many many thanks.

A similar question: How to upload a file to a WCF Service?
Some possible solutions:
Image Upload Web Service in C#.NET
Upload any type of File through a C# Web Service
Progress Indication while Uploading/Downloading Files using WCF
I would avoid allowing anyone to write files to a directory. I know you have set up permissions to help guard against anything bad happening, but it is still setup to where anyone can read/write to it, not just to person you've told the URL to. Security through obscurity is not a best practice.
What kind of webservice are you using? WCF, SOAP, something else all together? I would have the file upload still be a service call (not just some PUT command to a directory). That way you can still apply security if needed. When you get right down to it, a file is nothing more than an array of bytes, so you can have your web service accept an array of bytes and write it out to the correct location. If I had a better idea of what technologies you are using (php, asp.net, jsp, etc) Then I might be able to make more precise recommendations.
HTH
You can use SOAP attachments, or if not using SOAP, something similar - specifying filename, content type and binary data, Base64-encoded.
OK, this is impossible, but I will try to explain the situation here.
Let's say we have cases, that we need a fast setup of a web server in order to have a simple soap web service running (querying a db and so on).
In VS though, upon debugging a web project, it creates a quick ASP.NET development server without relying on the actuall IIS that might be installed on the PC.
Is there any project that does something like that?
This would be ideal for small projects, where a simple executable would get a server ready to go and would allow web services to be executed right away.
I have looked at some stuff over the net like http://msdn.microsoft.com/en-us/magazine/cc163879.aspx and http://mtaulty.com/CommunityServer/blogs/mike_taultys_blog/archive/2004/05/24/4479.aspx but they seem to be quite outdated and i am not sure how well they work (havent tested them thoroughly)
EDIT: I have build an application like the one you suggest. However, how can i implement HTTP GET/POST requests to the service using this method? I tried using WebGet after my operationcontract but it didnt work. For example, my service is at http://localhost:8080/Service and i would like to use it such as http://localhost:8080/Service/getMethod?x=2.
I believe that the development server used by Visual Studio is based off of the Cassini code base (of which there is a fork here). I also found this article on hosting the asp.net runtime. It was also created a while back (2004), but has been updated since (2008). I think a lot of the core concepts are probably still the same.
Another approach would be a roll-your-own web server using the HttpListener class. This could take some work if you want to use it for hosting asmx type services, but if you were doing RESTful services, it isn't too bad of an option (this is actually how RavenDB works if you are not hosting it under IIS).
A WCF service can be hosted in almost any kind of application, including a Windows Service or a console application. There is no need for a web server at all.
Alright,
i've done it so im posting it here to help anyone who has issues with similar problems.
Create your WCF Service file as usual and then by using ServiceHost (or WebServiceHost) you can easily create a WCF service.
In order to use GET http requests to make it simple to communicate with mobile devices (such as iphone) you can use WebGet above your service methods and make sure you manually add a service endpoint using WebHttpBinding for WebServiceHost or WebHttpBinding with an WebHttpBehavior for ServiceHost.
Then you can call your service methods such as http://localhost:port/webhttpendpointaddress/mymethod?x=2.
I am trying to create simple flex application, which uses django as a back-end part. Have a question:
Usually when I run my application Flex Builder creates a file in a directory on my local PC and then opens a browser and points to it. Everything was fine, but when I decided to link django server to flex applications via xml data providers I started to get security errors. (Related to absence of crossdomain.xml). When I created the file and put it on the server:
<?xml version="1.0"?>
<!-- http://www.foo.com/crossdomain.xml -->
<cross-domain-policy>
<allow-access-from domain="http://127.0.0.1:8000"/>
<allow-access-from domain="127.0.0.1"/>
</cross-domain-policy>
Then tried the application again, I got error in console of my FB Error: Request for resource at http://127.0.0.1:8000/go/active/ by requestor from file:///Users/oleg/Documents/FB3/usersList/bin-debug/usersList.swf is denied due to lack of policy file permissions.
I don't know how to fix the error. But also the question is there a way to configure FB3 to put my swf files to the server directly, so I will not need any crossdomain?
Thanks
Oleg
We struggled with this a lot. The Flex security stuff didn't strike me as well built, but perhaps we just had different approaches in mind than Adobe's developers. The solution that worked for us was to serve both the SWF and the dynamic data from the same host and port.
On our development boxes, we tell Apache to serve the SWF from a directory in the workspace, and the dynamic data from a local copy of the app. When we push to production, SWF and app get pushed simultaneously to the same virtual host.
If that's inconvenient for you, the Apache ProxyPass directive can be used to make Apache front for other servers. I've not used that in production, but it's been very handy for developer setups.
I don't know a way to get FlexBuilder to automatically deploy your changed SWF; you could certainly look into an automation approach (like Maven and Flex-Mojos) to make that happen.
That said, getting rid of that error is usually just a matter of adding a policy file to the server.
The second error is caused because you're trying to fetch http resources from a "file" location. My recommendation is that you change your Flex Builder project so it outputs to a location within the Django web site, rather than to the flex-bin directory. This setting can be changed in the properties dialog of the project. Then, you should be able to have your front-end and back-end share the same protocol and domain.
