All the questions you are asking can be easily answered by writing some code
and playing around with paginated lists for about fifteen minutes. Maybe
you should consider using DisplayTag instead of paginated lists since that
will make your life easier and you won't have to worry about writing Java
code to handle paging. Using either method carries approximately the same
performance hit. As mentioned earlier, if performance is your goal, write
vendor specific SQL code to return smaller result sets.

Subject: what does the PaginatedList method means ?
Dear Sir:
After we called the iBatis queryForPaginatedList(), we get a list of
type PaginatedList.
Let us call it queryResultList;
The PaginatedList has several methods like:
void gotoPage(int i);
boolean nextPage();
boolean previosPage();
What does these methods mean ?
What I want is to get a list to be returned to client side to be
displayed.
Let us call it toBeDisplayList;
1) I want to go to page 5, so I write the following statement
queryResultList.getoPage(5); What does this mean ?
Suppose the queryResultList have 600 element originally, and each page
display 30 elements,
after calling queryResultList.getoPage(5) , does the queryResultList
become a subList that begins with the 121th element ?
2) I am in page 1, and I want to go to next page
boolean ok = queryResultList.nextPage();
The ok is true.
Does the queryResultList become the sublist that begins from 31th element
?
Do I need to call a subList method to return a sublist that I want to
display ?
Thanks,
John Chien
