Paging records

Hi,

Ive been researching how to implement paging in my JSP. I can allow a user to select teh number of records they want to display and then I need to implement this functionality. I will probably need to write a custom tag to do this but Im not overly sure. Could someone help me out?

Thanks,
Sarah

There are a number of ways to do paged table displays. Custom tags work, Struts iterators work, I've done a number of things in straight Java over the years (some of them pretty ugly ), and most recently, there's an extended data table display in the apache MyFaces project that does multipage display.


Customer surveys are for companies who didn't pay proper attention to begin with.

Hi,

So if I were to write a custom tag, how would I go about dividing my list? And displaying the particular pieces of it that I need? As in if a user hits on page 2, should I be going to my action class or should the custom tag handle it?

Sarah, this is a subject that has been discussed many times in this forum. Take a look back and you will find topics that address this issue.

My tactic has been to have the database do the dicing and slicing of the large dataset, rather than the UI layer. After all, why send data to the front end that is just going to be ignored?
