Using Geoprocessing in a service cause exception.

I 've created a Toolbox tool in ArcMap. It's a very simple tool designed to clip raster data. It works fun in ArcMap. And I used it in a console application. Here is the code:

ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.EngineOrDesktop);
Geoprocessor gp = new Geoprocessor();
gp.AddToolbox(@"D:\Documents\ArcGIS\clipEnvelope\clipService.tbx");
gp.OverwriteOutput = true;
string rectangle = "94736.18 17841.65 97550.74 20512.60";
IVariantArray parameters = new VarArrayClass();
parameters.Add(rectangle);
gp.Execute("clipRaster", parameters, null);

The tool receive a envelope as parameter and "rectangle" in the code represent a envelope. The code works fun in console application. I used the same code in a ASP.NET Web application. And I received a COMException at the row "gp.Execute("clipRaster", parameters, null);".
Here is the detail of the exception:

用户代码未处理 System.Runtime.InteropServices.COMException

I am developing a ASP.NET Web application. So how can I solve the problem? I would be very grateful for the help.

You would need to initialize Server license, instead of Engine or Desktop, in your code since it is a web application (http://desktop.arcgis.com/en/arcobjects/latest/net/webframe.htm#aoinitialize.htm ). Engine and Desktop license are one user per license mode.

Just FYI, it's not really recommended to use ArcObjects SDK in ASP.NET web applications. Server Object Extension would be a better option to use ArcObjects in web environment (http://desktop.arcgis.com/en/arcobjects/latest/net/webframe.htm#652a31ce-4f02-43b5-bba9-9db26ce231af.htm ).
