custom policyquestion -- dotnet web services enhancements

I have a webservice which is built on WSE 2.0.

On the client side I am using .net2.0 and WSE 3.0. I added webreference to
the above webservice.
And also I added a custom filter to add some custom header elements.

Here is my question
Why the custom filter ProcessMessage method is not getting executed when I
invoke a webmethod/
I would really appreciate you help.

Here is some of my code from the web.config

<configSections>
<section name="microsoft.web.services3"
type="Microsoft.Web.Services3.Configuration.WebServicesConfiguration,
Microsoft.Web.Services3, Version=3.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35" />
</configSections>

<microsoft.web.services3>
<policy filename="wse3policyCache.config"></policy>
<diagnostics>
<trace enabled="true" input="InputTrace.webinfo"
output="OutputTrace.webinfo" />
</diagnostics>
</microsoft.web.services3>

I created a configuration policy file called "wse3policyCache.config"

policies xmlns="http://schemas.microsoft.com/wse/2005/06/policy">
<extensions>
<extension name="requireActionHeader"
type="Microsoft.Web.Services3.Design.RequireActionHeaderAssertion,
Microsoft.Web.Services3, Version=3.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35" />
<extension name="customFilter"
type="CustomPolicy.CustomPolicyAssertion, CustomPolicy"/>
</extensions>
<policy name="ClientPolicy">
<requireActionHeader />
<customFilter />
</policy>
</policies>

I created a policy assertion class(CustomPolicyAssertion) and soapfilter
class(ClientOutputFilter )

using System;
using System.Collections.Generic;
using System.Text;
using System.Security.Cryptography.X509Certificates;
using System.Xml;
using Microsoft.Web.Services3;
using Microsoft.Web.Services3.Design;
using Microsoft.Web.Services3.Security;
using Microsoft.Web.Services3.Security.Tokens;

namespace CustomPolicy
{

public class CustomPolicyAssertion: PolicyAssertion
{
public override SoapFilter CreateClientOutputFilter(FilterCreationContext
context)
{
return new ClientOutputFilter ();
}

public override SoapFilter CreateClientInputFilter(FilterCreationContext
context)
{
return null;
}

public override SoapFilter CreateServiceOutputFilter(FilterCreationContext
context)
{
return null;
}

public override SoapFilter CreateServiceInputFilter(FilterCreationContext
context)
{
return null;
}
}
}

using Microsoft.Win32;
using System;
using System.Xml;
using Microsoft.Web.Services3;
using System.Diagnostics;

namespace CustomPolicy
{
public class ClientOutputFilter : SoapFilter
{
public ClientOutputFilter()
{
}

public override SoapFilterResult ProcessMessage(SoapEnvelope envelope)

{
EventLog.WriteEntry("OutputFilter", "Processmessage");

//write code here to modify

return SoapFilterResult.Continue;
}
}
}

Hi Pablo,
Thanks for the quick response. I did not add clientpolicy to the proxy, But
now i do. Still not executing the ProcessMessage method

Here is the code
[Microsoft.Web.Services3.Policy("clientpolicy ")]
public partial class ServiceProxyWse :
Microsoft.Web.Services3.WebServicesClientProtocol. And also i don not see a
setpolicy method in my web proxy class.

Thanks
Senthil

Hi Ken,

Did you set the "ClientPolicy" policy in the web service proxy ?. By the
way, WSE 2.0 and WSE 3.0 are not interoperable, you are going to need a lot
of plumbing code to make them work together.

Hi Pablo

I got it to work. When i added a webreference on the client it created two
classes one with WSE at the end. On the client code I was using a proxy class
without WSE.
I changed the client code to use class with wse. Everything works now.

Thanks
