SQL Loader fails to process string columns with more than 255 characters

Question

Hi all,
I am using LKM file to sqlldr(oracle) to load data from flat file to oracle. I am aware of the fact that if you don't specify length of the input character data, sqlldr uses default of 255 characters. But, in my source datastore I have specified the column length to be 1000, but sqlldr still fails to process records with more that 255 characters.
Any idea how to change this behavior of sqlldr?
Appreciate your response.

You can change the step "Generate CTL File"
and replace the section:
          } else {
          // The source column is a STRING => no options to add
               format = "";
          };with
          } else {
          // The source column is a STRING => add char(length) for length greater than 255
               taille = new Integer(colPrecision).intValue();
               if (taille > 254)
               format = "CHAR("+colPrecision+")";
               else
               format ="";
          };
