I want to display few rows per jsp page, the number of rows should be selected by the user. I'm executing the query in a stateless session bean. I have a Java bean wrapper around it, whose methods I call in my jsp page. Can I get selected number of rows in the resultset itself, ie, specify the number of rows I want from the query when creating the query itself ? Is this why Scrollable resultsets are used ? And do preparedstatements support scrollable resultsets ?
Any clarifications regarding this will be helpful.

one possible soln ..
u can give the bean a session scope and get only required no of rows each time.
ans have a counter variable in bean and reset it on each call.
hope it will solve it..
