object doesn't support this property or method error while trying to access an existing method of a C# dll in JavaScript

Hi,

I'm seeing this error in my WebClient.

We use two virtual directories. And each uses different Application pools. One uses ASP.NET v4.0 and Other uses ASP.NET v2.0.

The WebClient files are in the virtual directory which uses ASP.NET v4.0 Integrated.

And we have a RPScript.js, RPEditor.aspx file and a RpEditor.dll file in the virtual directory which uses ASP.NET v2.0 Integrated.

And we have the below code in the RPScript.js file.

document.write('<OBJ' + 'ECT id="rpObject" onmouseover="OnMouseOver()" style="MARGIN-TOP: 20px; MARGIN-LEFT: 10px" height="360" width="650" classid="' + window.location.protocol + 'RpEditor.dll#Acc.Editor.RpEditor.RpEditorCtrl" name="rp" VIEWASTEXT><\/OBJ' + 'ECT>');

And window.location.protocol = "http:"

And the RpEditor.dll contains functions like Initialize, CreateReport functions.

When I try to access RPEditor.aspx from my WebClient I'm receiving the "object doesn't support this property or method" error in the RPEditor.aspx when I call rpObject.Initialize() function.

But I know the function exists in the dll.

Am I missing anything here? Please Advice.

Thanks.
