Executable app(.exe) not running via the ASP.Net Webservice(.asmx) - .net-4.0

Question

I want to execute a process from the ASP.Net Webservice(.asmx).
In the Webservice hosted directory, I have a executable app in "importerapp" folder of the webservice directory. My executable app is ( Named as Import.exe) is working good by double clicking.
My webservice is running with no error but the process is not executed.
[WebMethod]
[ScriptMethod(UseHttpGet = true)]
public string executeProcess(RunMode mode )
{
Process process = new Process();
process.StartInfo.FileName = Server.MapPath("importerapp/Import.exe");
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.Arguments = "mode=" + (int)_runMode ;
process.Start();
process.WaitForExit();
string output = process.StandardOutput.ReadToEnd();
string error = process.StandardError.ReadToEnd();
return("Job Submitted OK with params: "+_runMode + error
+ output +"Exit Code:"+ process.ExitCode );
}
In the browser, The output is as below.
<string xmlns="http://tempuri.org/">Job Submitted OK with
params: Exit Code:0</string>
That means, the "error" and "output" variable is null and exit code is 0 which means success.
But the processing is not doing anything, even not creating logfile( I am using nLog library).
Environment: WIndows7, IIS 7.5, .Net4.0, C#, ASP.Net
Please advise.
Thanks.

Job Submitted OK with params: Exit Code:0
This, according to your code, means that _runMode variable is not initiated. I think you forget to pass the parameter mode to your process
