Middle Tier issue (SOLVED)

[wjstarck]

I had Middle Tier working on a Amazon lightsail server, but I recently upgraded that install to 23.1.x

Now I can't seem to be able to login. The error I get is

Code: Select all

Server Error in '/OpenDentalServer' Application.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: Could not create type 'OpenDentalServer.ServiceMain'.

Source Error:


Line 1:  <%@ WebService Language="C#" CodeBehind="ServiceMain.asmx.cs" Class="OpenDentalServer.ServiceMain" %>

Source File: /OpenDentalServer/ServiceMain.asmx    Line: 1

Everything seems to be setup OK, and the application pool is set to Enable 32 bit applications.

Ideas?

Here are the contents of ServiceMain.asmx.cs:

Code: Select all

using System.ComponentModel;
using System.Web.Services;
using OpenDentBusiness;

namespace OpenDentalServer {
	/// <summary></summary>
	[WebService(Namespace="http://localhost/OpenDentalServer")]

	[ToolboxItem(false)]
	public class ServiceMain:System.Web.Services.WebService {

		///<summary>Pass in a serialized dto.  It returns a dto which must be deserialized by the client.</summary>
		[WebMethod]
		public string ProcessRequest(string dtoString) {
			return DtoProcessor.ProcessDto(dtoString,Server.MapPath("."));
		}

	}
}

Looks like I've had this issue once before:

https://www.opendentalsoft.com:8085/for ... ier#p32040

I have checked and rechecked my config multiple times after following the Middle Tier installation instructions.

1) I have my Open Dental program folder present on the Middle Tier server
2) I've copied the contents of the /bin folder in the OpenDentalServer project to the /OpenDental/bin folder on the Middle Tier server
3) I notice that there are ServiceMain.asmx and ServiceMain.asmx.cs files in both the Open Dental program folder *and the /bin folder. IIS loads the ServiceMain.asmx from the Open Dental program folder. Is this correct? What about Web.Config (there's one in each location as well)?

[wjstarck]

OK fixed.

I had to uninstall and reinstall IIS to get it to work.

Thanks to the Middle Tier Support team for taking a look at it yesterday.
