Problem in Inserting Data in Excel after Publish

Question

Hi,
    I created a Application using ASP.net with C# , OLEDB provider which can connect either of the 3 databases (Excel/Access/SQL).
Now i am using Excel as the Database.
Before publishing, In the Local system the data is saved in the Database and Displayed in the grid
after Publishing in the server, the value is not saved in the database , it is not showing any error also.
Can  any one help me to resolve this problem.
Thanks in Advance
