Using Query parameter    lt a href  edit jsp userId   user id     gt      Using Hidden variable     lt form method  post  action  update jsp  gt              lt input type  hidden  name  userId  value    user id   gt         you can send Using Session object      session setAttribute  userId   userid     These values will now be available from any jsp as long as your session is still active       int userid   session getAttribute  userId

Use sessions  On your search jsp  Put your scard in sessions using session setAttribute  scard   scard       the 1st variable is the string name that you will retrieve in ur next page and the 2nd variable is the its value i e the scard value   And in your next page you retrieve it using session getAttribute  scard    UPDATE   lt input type  text  value   lt   session getAttribute  scard    gt    gt
