.NET Forum / ASP.NET / Web Services / January 2006WSE2 to WSE3, what to do with the pipeline ?
Hi, I'm converting an app from WSE2 to WSE3. The WSE2 app contains the following code for 4 different Web services; service.Pipeline.OutputFilters.Add(OutputFilter); service.Pipeline.InputFilters.Add(InputFilter); There is no service.Pipeline in WSE3. I've seen some info that says I should use a Policy Assertion. But is there a tutorial that will help me re-wrte this code ?  SignatureRegards DaveP UK Hi Dave, I have written something regarding this topic in my weblog. http://weblogs.asp.net/cibrax/archive/2005/07/19/419921.aspx I hope this can help you.

But is there a tutorial that will help me re-wrte > this code ? Pablo, I have a problem. I can't find the proxy class ! My application is in VS2005, with the WSE3 tool and WSE3 turned on. When I want to create a proxy I do Add WebReference, then put in the WSDL, say http://localhost/EchService.asmx?WSDL. I call it es Then in my app I can say es.EchoService myService = new es.EchoService(); But I can't find the proxy code. Also, I can't use SetPolicy as this does not appear as a property of myService. It looks like my WSE3 implementation isnt complete. Can you suggest anything ? of myService SignatureRegards DaveP UK > Hi Dave, > I have written something regarding this topic in my weblog.

I just get EchService.discomap and EchoService.wsdl how to I get the proxy class source code ? SignatureRegards DaveP UK > Pablo, I have a problem.

ASP.NET automatically creates the proxies for the web services. You will able to find two proxies for your service: 1. es.EchoService 2. es.EchoServiceWse (This is the proxy for WSE) It will be better if you create the proxy class using the tool WSEWsdl3.exe Regards, Pablo Cibraro http://weblogs.asp.net/cibrax http://www.lagash.com >I just get > [quoted text clipped - 45 lines] >> > > re-wrte >> > > this code ?

EchoServiceWse allows me to SetPolicy. I don't understand why I can't see the source code for the classes, like EchoService.cs and EchoServiceWse.cs. The next step, I think, is to create a Policy file, and to name a policy, so that I can do EchoServiceWse.SetPolicy("myPolicy"); Do I use the Wse3 Tool to cfreate the policy xml file, or do it by hand ?

[quoted text clipped - 98 lines] >> >> >> > > re-wrte >> >> >> > > this code ? Pablo, I've tried using the Wse 3 tool, but it won't work for me. The tool seems to be just for security settings. I'm not doing any security. The web services that I'm calling ask for an id, or 'handle', to be placed in the SOAP header. I was just using the CustomInputFilter and CustomOutputFilter to do this, but this seems to be difficult in WSE3. What is the best way to put a string in the SOAP header on the request, and then to check what value is in the SOAP Header when my client receives the response ?

Hi DaveP, Are you using WSE only to add a soap header to the message ?. That can be done with a simple web service without using WSE. WSE is usefull when you need to add support for different WS-* protocols to your service. For example, public class MyService : System.Web.Services.WebService { public MyHeader CustomHeader; [WebMethod()] [SoapHeader( "CustomHeader")] public void MyWebMethod(string value) { } } /// <remarks/> [XmlRoot("MyHeader", Namespace=http://temp.uri")] [XmlType(Namespace=http://temp.uri)] public class MyHeader: SoapHeader { /// <remarks/> public string StringValue; } Regards, Pablo Cibraro > Pablo, > [quoted text clipped - 133 lines] >> >> >> >> > > re-wrte >> >> >> >> > > this code ? Thanks Pablo, this looks useful. I'm calling 4 Web services from a web app, and each time I call them I will need to set a different value. When they return I need to get the value from the SOAP Header that is returned. So before the call can I set the value in the SOAP Header class, for example MyHeader.SetValue("thisValue"); MyService1.MyWebMethod("blah"); string OutHeader = Myheader.GetValue(); MyHeader.SetValue("thatValue"); MyService2.MyWebMethod("bleh"); string OutHeader = Myheader.GetValue(); Does this look right ? I'll try it anyway. SignatureRegards DaveP UK > Hi DaveP, > Are you using WSE only to add a soap header to the message ?. [quoted text clipped - 164 lines] > >> >> >> >> > > re-wrte > >> >> >> >> > > this code ? Pablo, I'm calling Web services. I have no control over them. They are Java, and they are part of a vendor product. So I have to add values to the SOAP header without changing the Web service.

Hi DaveP, Ok, you can do the same on the proxy class for the web service. I mean, you can define a custom header in the same way. Does it make sense ? Regards, Pablo Cibraro. > Pablo, > [quoted text clipped - 182 lines] >> >> >> >> >> > > re-wrte >> >> >> >> >> > > this code ? Pablo, thanks, it makes sense. But.. this takes me back to my previous problem. My client is a Web App built in VS2005, and when I do an Add Web Reference I don't get the proxy class, I just get the discomap and wsdl. I can try it by using the command line tool, WseWsdl3.exe, but then I have to copy it back into my VS2005 structure. When I've finished this I have to document it as the way that our developers should work. It looks bad if I tell them to use Visual Studio, but to use a command line tool every time they have to add a Web reference ! Do you understand my problem ? Do you know if this will be fixed in VS2005 some day ? SignatureRegards DaveP UK > Hi DaveP, > Ok, you can do the same on the proxy class for the web service. [quoted text clipped - 189 lines] > >> >> >> >> >> > > re-wrte > >> >> >> >> >> > > this code ? Yes, I understand your concern very well. It is not a problem with VS2005, it is a problem with ASP.NET because it uses a new application model based on different folders (e.g, App_Code to store the code, App_WebReferences to store the web services proxies). The ASP.NET team in Microsoft will also provide the previous model (The model used by ASP.NET 1.1 and VS2003) in the next version, so you will able to chose the compilation model for your application. This is great news for many people, including me :). Regards, Pablo Cibraro. > Pablo, thanks, it makes sense. But.. this takes me back to my previous > problem.
