        prepstat.setString(2, projectID);
        prepstat.setString(3, positionID);
        prepstat.executeUpdate();   // this is where the exception occurs

Answer 1

Did you specifically state that the connection was readwrite in your connection string?

I am not familiar with JDBC, but ODBC would be:

"Driver={Microsoft Excel Driver (*.xls)};" & _
"DBQ=C:\MyFolder\MyWorkbook.xls; ReadOnly=False;"

Excel is read-only by default: http://support.microsoft.com/kb/257819

在创建DSN时只需要取消选中只读即可。
