loading large amount of data into jTable

["Lim Hock-Chai" <Lim.Hock-Chai@xxxxxxxx>]

I've two questions regarding loading large amount of data to jTable:
 
Currently, I load the data into a Vector.  The Vector is then passed to a class 
that extend AbstractTableModel.  This works well, however, I encounter the 
following two problem: 
 
1) When user's request result in a large amount of data, the program receives 
java.lang.OutOfMemoryError.  In RPG, we typically load one page at a time using 
subfile, which result in good performance and user knows to redefine the 
request to get to the page he/she wanted.  What is the typical way of handle 
this in java?
 
2) I would like to display the table to the user as the data is being loaded, 
much like open a large Excel spreadsheet, user is able to scroll down as the 
data continue to load.
 
thanks
