How to process 'db-text records'

  I have following records (length 70char) in a DB:
  "remark line 1"
  "remark line 2"
  "remark line 3"
  "remark line 4: how about this"

  The db keeps 'remarks' line by line, length 70chars

  I want to display them in a JSP and process them without changing their
  layout. I can 'read' and 'display them using jsp/html textarea. The user
  can change the info but how do I send them back in same format?

  user alteration, html textarea now has:
  "remark line 4: how about this"
  "remark line 3"
  "remark line 2"
  "remark line 1"
  "user adds this line"
  "and adds this spaced...................line"

  I can receive this textarea into my servlet but I think the result will
  be 1 string. This string can be divided in 70-char fields but: how can I
  keep this info line by line?
  All opinions welcome.
