Managing Result Set Data

Question

I am trying to display a large amount of data on a web page - enough data that I need to partition it into smaller sets of data to show on each page. It is also too much data to cache all of it.
The first idea I had was to use the rownum in the sql statement. For example for page 3:
SELECT * from table_name where rownum between 200 and 300
However I found this is not an appropriate use of rownum.
The only other idea I have is something like the following, where I return all the data and sort out what I want. But I know this is a common issue, and there has to be a better way to return blocks of data. Anyone have a suggestion?
int pageCount = 100;
int rowNumber = 0;
while(rs.next())
if( rowNumber < storedRowNum ) //row is less than specified range - do nothing
else if( rowNumber > storedRowNum + pageCount ) //row is greater than specified range - exit loop
else //this is the data range I want for this page - store in a Collection to display
}
