I built the example in the MSDN documentation in the Section 'Building a
Basic .NET Remoting Application'. When I try to execute the Client.exe I get
the following error.

'System.Runtime.Remoting.RemotingException' occurred in mscorlib.dll
Additional information: Requested Service not found

How do I find out what service was not found?

Thanks for your helpful comments,
Ivan

Hi
If you are using app.config for configuring the remoting server and client
information then make sure the remoting server application's app.config has
the
<system.runtime.remoting> section and contains the service information.
Also ensure that the remoting client application's app.config hsa the
<system.runtime.remoting> section and contains the client configuration.

The particular error indicates that the remoting server information
contained within <client> is not correct.
<client>
<wellknown
type="RemotableType, RemotableType"
url="http://localhost:8989/RemotableType.rem"
/>
</client>
Here 'RemotableType.rem' is the objectURI attribute value you had given in
remoting server application configuration.

Hope you find this useful.

Hello blore,

I agree with your diagnostic. I went and very carefully inspected both
configuration files (the content of these configuration files is also
included in the MSDN Example source code) and I found that they are exactly
as you indicate that they should be. Since these files are small I am
including the text in this message.

In the example files I've tried both, the http and the tcp variations, with
the same results.

Thanks,
Ivan

<configuration>
<system.runtime.remoting>

        <wellknown

    />
    </service>
    <channels>
        <channel ref="http" port="8989"/>

Hi Ivan
I tried with a sample program and could replicate 'Requested service not
found' Remoting exception only when i give a wrong objectURI. if i don't run
the server, or change the other configurations this specific exception
doesn't occur. Hence according to me, giving a wrong objectURI is a reason
for the exception. I didn't come across other situations where in the same
exception is thrown.

Hi blore,

I found the problem!!!. It was the upper case "O" in
ObjectUri="RemotableType.rem"

... and this is after a very long lifetime of writing "c", and though I
don't think it is an excuse, I am somehow dissapointed that the compiler did
not flag this one out.

On a related subject, do you know if this area of the framework (remoting)
is going to change substantially in Version 2.0?, and if not, and you have
some ideas, what are a couple of good books on this subject?

Thanks,
Ivan

Hi,

I am also facing a similar Problem. On running the client Application I get
an error Requested Service Not Found. The o in Object Uri is small case only.

The web.config file is as follows:

configuration>
<system.runtime.remoting>
<application>

<service>
<wellknown mode="SingleCall" type="ClsRemoteObject.Maths,
ClsRemoteObject" objectUri="Maths.soap" />
</service>
<channels>
<channel ref="http" port="80"/>
</channels>

</application>
</system.runtime.remoting>
</configuration>

The client side Remoting code is as follows:

Dim channel As HttpChannel = New HttpChannel
ChannelServices.RegisterChannel(channel)

RemotingConfiguration.RegisterWellKnownClientType(GetType(Maths),
"http://localhost:80/TestClsRemoteWeb/Maths.soap") '"tcp://Anita:8085/Maths")
'

Here TestClsRemoteWeb is the Virtual directory.

Help me out.
