Visual WP For Excel Bulk Insert to SQL Server Table

Dear All ,

I have written below code in simple asp.net web application , It is working fine . But when I converted into SharePoint 2010 Visual web part It it giving error as below 

Error 1:
<Excel Path >for System upload .xls' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.

Error 2 :
Microsoft.ACE.OLEDB.12.0' provider is not registered in the local 

Error3:
microsoft.jet.oledb.4.0 is not registered


This Error is coming when I am using that app from client machine. 

try
            {
                if (fileuploadExcel.HasFile)
                {
                    //file upload path
                    string fileExtension = Path.GetExtension(fileuploadExcel.PostedFile.FileName);
                    string path = fileuploadExcel.PostedFile.FileName;
                    if ((fileExtension == ".xls") || (fileExtension == ".xlsx"))
                    {

                        //if (fileExtension == ".xls")
