I have no other choice but to  do that way .

because , my jsp table's column is getting stretched from the DB's
long text.

so, i want to make it formatted before putting into the table.
i would like to add <br> tags so that in the final html , it will
wrapped and will give  newlines.

so, i need that method.

do you know any other easy alternative ?

What is the reason for the '-1' placed after
the length() call?

If splitting on word boundaries isn't an issue (and Chris Dollin's
solution is a better approach for that problem) then there's no
need to look at every character:

    public String chopString(String s, int blkSize) {
        String ns = "";
        while (s.length() > blkSize) {
            ns += s.substring(0,blkSize)+"<br>";
            s = s.substring(blkSize);
            }
        ns += s;
        return ns
        }

Here is another implementation:

public class BreakString
  {

  /**
   * break up a String into lines, and separate them with <br>,
   * breaking into lineLength chunks, ignoring word boundaries.
   * This code is optimised for speed by attempting to keep the inner
loop
   * as tight as possible, at the expense of some extra setup work.
   * @param s string to break
   * @param lineLength length of desired lines (not counting the
<br>).
   * @return string with <br> separators inserted.
   */
  public static String breakString(String s, int  lineLength)
     {
     final int stringLength = s.length();

     if ( stringLength <= lineLength )
        {
        return s;
        }

     // count of one or more lines, including partial lines.
     // Last line may be full or partial.
     final int lines = (stringLength + lineLength - 1 ) / lineLength;

     // compute space needed for original string
     // plus a <br> on all but the last line.
     final StringBuilder sb =
     new StringBuilder(stringLength
                       + ( "<br>\n".length()
                           * ( lines-1 ) ) );

     // do all but the last line, possibly 0 lines.
     final int startOfLastLine = (lines-1) * lineLength;
     for ( int i=0; i < startOfLastLine; i+= lineLength )
        {
        // copy over one complete line.
        sb.append( s.substring( i, i+lineLength ) );
        sb.append( "<br>\n" );
        }

     // copy over the last line, full or partial without <br>
     sb.append( s.substring( startOfLastLine, stringLength ) );

     return sb.toString();
     }

  /**
   * main, test driver
   * @param args not used.
   */
  public static void main ( String[] args )
     {
     System.out.println(breakString("123456789012345678901234567",
3));
     System.out.println(breakString("123456789012345678901234567890",
30));
System.out.println(breakString("1234567890123456789012345678901", 30
));

System.out.println(breakString("123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123",
30) );
     }
  }

}
