In FlexBuilder 3, there are two items under the 'Data' menu to import and manage web services. After importing a webservice, I can update it with the manage option. However, the webservices seems to disappear after they are imported. The manager does however recognize that a certain WSDL URL was imported and refuses to do anything with it.
How does the manager know this, and how can I make it refresh a certain WSDL URL?
In your src folder of the flexbuilder project you should see the generated classes. For instance, if you use the manager to generate the proxy classes for www.example.com you should see the folders /com/example with the generated proxy classes inside.
To consume these webservices in ActionScript use the statement:
"import com.example.*;"
To consume the webservice in mxml include the .as file using:
<mx:Script source="yourscriptname.as"/>
To refresh the generated proxy classes, consuming the latest WSDL, simply open the manager and select "update".
Also, I found this article very useful for consuming web services.
I hope that helps, the question was kind of vague about the problem.

I have inhherited a vs2010 c# web project (asp.net). It has a web reference to a web service. There's been a slight change to the service - a new operation has been added. I'd like to update the proxy class so that i can call the new operation but i can't find the class. I seem to remember there used to be a "show all files" button in solution explorer that would reveal the proxy class but i can see no sign of that. Unfortunately, i'm not able to refresh the proxy by pointing it at the web service metadata wsdl because vs is no longer installed on any pc that can reach the web service. Anyone know where i can find the proxy class?
It doesn't matter you can't find it in Visual Studio - you can always locate a proper file in your filesystem, under the project directory.
Problem was, the app was running - doh!
Yes, you are right. There is a "Show all files" icon in the tool bar. It will only be available when you have a project selected, so you want to select the web service's parent project:
Expand the service reference and under it the file called Reference.cs is the proxy class.
You should NOT be hand editing this though. You should make the changes to the service and then regenerate the proxy using the Update Service Reference right click option. But then if you really can't do that as you say, then just hand edit the file. But beware that any changes you make will be lost if someone does regenerate it again in the future. Very Risky! (I prey you are using source control)
There is a WSDL.exe command line tool.
Copy and execute this command line tool in the PC where you can have access to the WebService, it will generates the proxy again and you can replace them with the files in your project.

Is there some sort of configuration settings in FlashBuilder 4.5 where you can easily switch between webservice urls? Right now I have to delete and recreate the web service every time I switch from local to production and vice versa.
The need/requirement is this – Since I work in a startup, we keep changing servers, and their IP addresses. And being a service oriented application – I need to be able to edit the webservice endpoints in my Flex application in a easy manner every time this happens.
My Solution for this -
Assumption is that my webservice endpoint looks like this -
http:////ListAllServices/
1) Create a file config.xml in a folder named “settings” that sits in the root folder of your Flex application – outside the “src” folder. And the config.xml will be a simple xml file of the following format -
localhostTestFlexApp
At the end of this exercise the directory structure of your flex source code will look like this -
flex_src(root of the source code)
-com(some source folder)
–testapp
—view
—
-images
-settings
–config.xml
-appName.mxml
2) Now in your application code, setup a HTTPService object either in mxml or action script. Set the url of that object to this value- “settings/config.xml” – And the above xml fiel containing the current settings will be loaded into memory .
Now you can store these values in a singleton object and construct your Webservice call at runtime.
And whenever you want to move this to a new server in production, edit the tag of your config.xml and you should be good to go.
And this can be automated as well via the EnvGen ant task.
This is not the best way but yes it is very helpful while switching among servers.
Alrighty... The way I was doing it before in fact worked. The problem was browser caching.
For the benefit of others I modified the subsclass for the generated service and replace the wsdl variable with whatever endpoint I need.
We are hosting huge app for our cutomers. There are diffrent configuration and contents (images, user files). But the core code, directories structure, databse scheme is this same for every client.
I'm looking for a way to create one core code repository, so all clientes will use it. We do updates often, so this will make our live easyer.
The idea is to create the repo and In clients directories create just symbolic links to that repo direcories: bin, App_Resources, Css, SystemImages etc.
Is this a good idea? Will ASP.NET MVC app handle this correctly, or I've to add some code for it handle the 'virtual direcotories'?
I would suggest that you take a look Single-tenant and Multi-tenant applications even if you say that your code base is the same for every one.
Here is a nice Multi-Tenancy ASP.NET example
I would also suggest that you check http://appHarbour.com as you can easily push changes from your master repository to appHarbour using Git or Mercurial.
Regarding your exact question, I also keep static files in a custom scheme under Amazon S3, so each client can upload there own files, plus the ones I have and all is based on a single location that does not put more resources just to delivery static files.
You can see my live web application using this technique checking the View Source.
This is maybe a really simple question, but I couldn't locate an answer:
For a client I need to HOST a webservice. The client has sent me a wsdl file that the webservice should 'implement'. How do I go about that? I've generated any number of client-rpoxies but this is the other way around. I can use both ASP.NET 2.0 webservices or Windows Communication Foundation.
wsdl.exe /server.
Generates an abstract class for an XML
Web service based on the contracts.
The default is to generate client
proxy classes. When using the
/parameters option, this value is a
element that contains
"server".
You can do a similar thing with svcutil.exe for WCF- something like:
svcutil.exe thewsdl.wsdl /language:c# /out:ITheInterface.cs (I've not tested this).
Edit- John Saunders makes a good point in his answer to favour the WCF approach- I recommend this too.
Actually, you should do this with svcutil.exe, not with wsdl.exe. WSDL.EXE is part of the ASMX web service technology that Microsoft now considers to be "legacy" code, which will not have bugs fixed.
You can do plenty with that WSDL (wissd'le) file.
From doing the WS Class manually to use the Auto Generated class from wsdl.exe
let's imagine that, for your example, you have this WDSL (tooked from WebServiceX.Net)
to create a C# auto generated proxy you go to your command prompt and write:
wsdl /language:cs /protocol:soap /out:C:\myProxyScripts http://www.webservicex.net/TranslateService.asmx?wsdl
Note: inside your C:\Program Files\Microsoft SDKs\Windows\v6.1\Bin folder you will find wsdl.exe or just do a dir /s inside your C:\Program Files\
if you want in Visual Basic, just use /language:vb or /l:vb
/language:
The language to use for the generated proxy class. Choose from 'CS',
'VB', 'JS', 'VJS', 'CPP' or provide a fully-qualified name for a class implementing System.CodeDom.Compiler.CodeDomProvider.
The default
language is 'CS' (CSharp). Short form is '/l:'.
This command will put inside your C:\myProxyScripts the auto generated proxy.
if your using the WSDL file in your computer, just change the URL to your full path, for example
wsdl /language:cs /protocol:soap /out:C:\myProxyScripts C:\myProxyScripts\myWsdlFile.wsdl
Note: your Generated proxy will be called the Service Name, the one you have specified, in our example, as:
<wsdl:service name="TranslateService">
I hope this helps you, understand the WSDL, the Auto Generated Proxies and that you can manage now everything in your end to fulfill your client wishes.
You can use the wsdl utility from microsoft to generate the server interfaces and implement them
Here is a short description of the WSDL utility.
wsdl.exe -
Utility to generate code for xml web service clients and xml web
services
using ASP.NET from WSDL contract files, XSD schemas and .discomap
discovery documents. This tool can be used in conjunction with disco.exe.
We have some Modules which have their own remote objects configured in remoting-config.xml. Each is packaged and deployed as separate web archives (WAR). For ex. Module1.war, Module2.war.
We are trying to integrate them in a flex application which is deployed in a separate web app. For ex. MainApp.war.
The remote objects work fine when invoked from within Module1.war and Module2.war. But the java remote objects are not getting invoked when called from the main flex application MainApp.war.
I have looked at Flex Developers guide and flexcoders Yahoo group.
How are you configuring your remote objects? Are you passing the path to services-config.xml in the "-services" compiler flag? If you are, I would avoid doing this, since it doesn't give you much flexibility in the location of your services endpoints.
Christophe Coenraets has a great article on best practices for configuring RemoteObject and other data access classes in Flex. The general idea is to externalize the URLs into an XML configuration file, load that with an HTTPService when the application starts up, then use the URLs to configure your Channel/ChannelSet which are binded into the RemoteObject.
