Microsoft Access can’t open the database

hi all,

I have a problem with devoloping an asp program , that shouldl open ms-access using 

Set objAccess =  Server.CreateObject("Access.Application")

here is my asp code.

<%
    Dim objAccess
    Set objAccess = Server.CreateObject("Access.Application")
        objAccess.OpenCurrentDatabase request("APPL_PHYSICAL_PATH") & "databasename.mdb"
    objAccess.DoCmd.OutputTo 3, "reportName", "Snapshot Format (*.snp)", "snapshotname.snp", 0
    objAccess.DoCmd.Quit 2
%>

It shows the error in my IE browser.

error '800a1eba'

if i trap the error through asp code it shows below message.

Microsoft Access can't open the database because it is missing, or opened exclusively by another user.

What should be the reason of this error ?

Please help me?
Thanking in advance.
