Regarding java.sql.PreparedStatement

Question

hi all,
Iam using mysql as backend and working using servlets/JSP's.i have been trying to find out datatypes of fields using ParameterMetaData Interface using PreparedStatement.But iam getting an error stating that it is not implemented in com.mysql.jdbc.NotImplemented:Feature not implemented.
Here is my code
                       Class.forName("org.gjt.mm.mysql.Driver");
                Connection con=DriverManager.getConnection("jdbc:mysql://localhost/"+"uniguru","root","");
                System.out.println("con="+con);
               PreparedStatement ps = con.prepareStatement("INSERT INTO linkstable VALUES(?, ?, ?,?)");
               try
                 ParameterMetaData pmd = ps.getParameterMetaData();
                 System.out.println("pmd="+pmd);
               for (int i = 1; i < pmd.getParameterCount(); i++)
                    System.out.println("Parameter number " + i);
                    System.out.println("  Class name is " + pmd.getParameterClassName(i));
                    // Note: Mode relates to input, output or inout
                    System.out.println("  Mode is " + pmd.getParameterClassName(i));
                    System.out.println("  Type is " + pmd.getParameterType(i));
                    System.out.println("  Type name is " + pmd.getParameterTypeName(i));
                    System.out.println("  Precision is " + pmd.getPrecision(i));
                    System.out.println("  Scale is " + pmd.getScale(i));
                    System.out.println("  Nullable? is " + pmd.isNullable(i));
                    System.out.println("  Signed? is " + pmd.isSigned(i));
               catch(SQLException e)
                    System.out.println(e);
               }Iam trying to write a generic servlet so as to insert any table values.Presently iam inserting values in a table named linkstable and i need to find out the datatypes.
Thanx in advance.

Have you tried to update to a newer driver?
It's the driver that says that the feature you are trying to use isn't implemented/supported by it.
