Welcome to fun world of coding.

Did you have a question you wanted to ask?

[sheldoncs]

I run the web service in the ie browser and it works fine but when I am calling the service from a client i get the response error:
Message="Client found response content type of 'text/plain; charset=utf-8', but expected 'text/xml'. The request failed with the error message: -- System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.UnauthorizedAccessException: Access to the path 'd:\logFile.txt'

[tlhintoq]

I run the web service in the ie browser and it works fine but when I am calling the service from a client i get the response error:

Ok. You get an error message. What is your question? What part of the error message are you not understanding?

Here's the part that seems significant to me:

System.UnauthorizedAccessException: Access to the path 'd:\logFile.txt' is denied.

I would guess you are writing to a log file that you don't have access to.

[sheldoncs]

Yes, I want to write the incoming soap request to logFile.txt. I have both the client and server on my machine - localhost. It does not make sense to me that I am getting the UnauthorizedAccessException because the file is on my local machine.

[tlhintoq]

I have both the client and server on my machine - localhost.

Are they both trying to access the same log file?

One file on hard drive means there should be only one class reading from it or writing to it. Any more than that risks simultaneous attempts to access a single file.

Your client and your server should be writing to different files.
Each one should have some type of Logging class that is responsible for the file read/write.
Everything else in the application should access a method of the logging class to cause a write. I do this by raising an event of "LogThis(string Message)"

By having one one point that is responsible for writing in the log you can easily change the format of the log since there is only one place to make the change. Maybe you want to change it from
12:34 pm - This Happened
to
15oct09 12:34:56.123 - This Happened.

[sheldoncs]

Actually no,

The client is calling the server awaiting a response and is not trying to access the logFile. On the other side the server gets the request and through the SoapExtension at the ProcessManager, the BeforeDeserialize option consist of a procedure which attempts to write the incoming SOAP Request to the logFile.

Hope this explains it. I would like to post the code but everything is at the office.

[sheldoncs]

forgot to tell you that the client is a vb form

[sheldoncs]

I got it to work. it was a permissions problem.
