Thanks
But it is nothing with "form" and "request".
Maybe I should make me more clear:
For the first time this JSP loaded, it is not sure how many rows of a table
needed by user. Then user choos a select_box to set the rows number and then
JSP was reloaded with table contain the number of rows user selected.
<select size="1" name=item_num
ONCHANGE="location=this.options[this.selectedIndex].value;">
<%for(int i=1;i<=5;i++){%>
<option
value="\AddQuotation.jsp?actionfrom=<%=request_from%>&row_num=<%=i%>"<%if(ro
w_num==i){out.print("SELECTED");}%> >-<%=i%>-</option>
<%}%>
</select>
But user may set other fields before setting the number of rows, so when the
JSP was reloaded, all filled fields ahould be cached, is it possible?
