jsp hibernate's paging code page 3/3

jsp page one:
Page
Total page
="/bussiness/clInfo/?method=queryWithPage&pageMethod=
first
Previous page
Next page
Last page
" paramName="PAGER" paramProperty="currentPage" paramId="currentPage">
front page
Explain this line: "/bussiness/clInfo/?method=queryWithPage&pageMethod=first
method=queryWithPage is because my Action inherits DispatchAction, and requires a method parameter
pageMethod=first is used to determine which operation to perform in the PageHelper class
