How Do I Debug This?

I have tested a web app and then deployed it to the site. When trying to open it I get an error that it cannot open the database.
The database is present and the path is correct.
The query is (see code snippet):

SELECT [Name] FROM [Cabinet] WHERE ([Position] = ?)

with default parameter = "District Governor"

The stack trace shows instructions leading up to the error but does not help me in determining why I cannot open the database file.  Can someone suggest how to use this to get to the why, not just the where?
From Default.aspx:
 
                        <asp:SqlDataSource ID="DGNameDataSource" runat="server" ConnectionString="data source=E:\VisualStudio2005\Projects\MD12S\App_Data\lions12s.s3db"
                            ProviderName="System.Data.SQLite" SelectCommand="SELECT [Name] FROM [Cabinet] WHERE ([Position] = ?)">
                            <SelectParameters>
                                <asp:Parameter DefaultValue="District Governor" Name="Position" Type="String" />
                            </SelectParameters>
                        </asp:SqlDataSource>
 
 
Stack Trace:

In your server, do you have you database in this path?
data source=E:\VisualStudio2005\Projects\MD12S\App_Data\lions12s.s3db
You need a valid path of your database after publishing your website.

Are you able to open the database on the development computer? It could be that the ASP.NET account does not have access permissions to the folder and drive. Try by copying the database file to the app folder.

in your question you said yourself that the database IS there at the specified path and now you accepted the answer which said database should be present at the path.

I failed to notice that the path in the error message and the xml snippet was incorrect. I apologize for my error.

The only resolution was to change the connection string to point to the |DataDirectory| rather than the physical path.
