Hi Arijit,

In the GDSF config file, the following element defines a DataResource:

    <GDSF:DataResource name="marksheet" dbms="MyDBMS">
        <GDSF:QueryLanguageRef name="sql"/>
        <GDSF:DatabaseRef name="test"/>
    </GDSF:DataResource>

You've named your DataResource "marksheet" so the parameter
"DataResource1" in the GridDataServiceConfig has to reference that name.
Change it to the following line:

    <GDS:Parameter name="DataResource1">marksheet</GDS:Parameter>

Also the location of the DBMS must include the port number. Change the
following line to include the port number:

    <GDSF:DatabaseManagementSystem
          name="MyDMBS" type="mysql" location="localhost" version="8.1">

Did you set up the Database roles for this database? There is an example
roles file (ExampleDatabaseRoles.xml) that comes with the
distribution. You'll need to add an element for your database, similar to
the following:

     <Database name="marksheet">
          <User dn="No Certificate Provided" userid="" pass=""/>
     </Database>

Let me know if you're still having problems.

Regards,
             Amy
