Hi All,
Can you please tell me the best way to do pagination in jsp.
I am using pager tag in the jsp. But the problem i am facing
is for every page link The query is fired to the database and it
is taking long time when the set of record are in lakhs.
I am using CachedRowset for this.
Can anybody suggest or give suitable example where i can retrieve
a set of record in one hit to database. store that in session object(cache)
and when i click my page link it should fetch the record from the object
in session and not from database.
Or is there any other way this can be best achieved.
thanks in Advance

I am trying to generate dynamic report for my project
Everytime i will be selecting different fields to be displayed
in the report based on some criteria . My idea is to set the data with is retrived
from resultset into my dto(data transfer object) and display this in jsp.( I am sucessfull in generating the
dynamic query).
But i am facing problem in set the values to dto since my query fields
vary every time. I am not able to understand to which dto property
i have to set values returned from resultset since i do not know in advance which fields will be selected
by user. All the values are coming from only one table.
I am not using any report framework for this project. Can anybody suggest how
this can be solved.

thanks in advance.

that error.
