I hope someone can help me i would be extremly greatful if someone could. Please

Hello --
One way to do this would be something like this:
1. Start out with a page where filtering parameters could be entered, submit to the servlet with a starting position of 0.
2. Grab all the rows from the oracle database, toss them in an array.
3. Draw items in a table from the starting position to the number of entries per page from the array.
4. Put a Previous and Next button on the results page to submit back to the servlet in step 2 where the starting position is the current position - number of results per page for previous, next is the has a starting position of current position + number of results per page. You'll want to do range checking, etc on this.
The key trick is to ask one servlet to do steps 2-4. I've used hidden variables on the form with some javascript to set the new starting parameter for previous and next. You could assemble a URL in javascript also.
There are probably slicker ways to do this, but for 2000 rows, it should probably work well enough.
Good luck.
