Web Service timeout from Sharepoint webpart

[Joe L via .NET 247]

I have written a web part. The webpart calls a web service toget info. I ran into problems with the webservice notresponding. We decided to have a cutoff for the time to waitfor a response from the web service. I am setting the Timeouton the webservice proxy before calling the webservice method. Iam not getting the results I expected. Below is the code andthe exception I get.

...
Results results = null;

try
{
MyWebService mws = new MyWebService();

// Set Timeout
mws.Timeout = 10000;

//get ws results
results = mws.getResults();
}
catch (Exception e)
{
// Throw exception to be caught in webpart control
throw new ApplicationException("Error calling MyWebService: ",e);
}
...

When Timeout is set to 10,000 miliseconds:

[WebPartPageUserException: The WebPart, Version=1.0.0.0,Culture=neutral, PublicKeyToken=750984491ffadf33 assemblyspecified in a Register directive of this page could not befound.]

When Timeout is set to 20,000 miliseconds:

System.Web.HttpException (0x80004001) Request Timed Out. (what Iexpect)

When Timeout is set to 30,000 miliseconds:

Again Request Timed out and some successful webpart loads (alsowhat I expect)
