Last month I built a JSP and Servlet-based list paging framework to take long lists of items and display them over multiple pages, much like google. Before I did this, I of course looked around for free, public implementations of the same thing as I see no reason to re-invent the wheel. However, I wasn't able to find one to fit my needs. JSP Tags has a pager library that seems to be very popular, but it requires roundtrips to the server for each page and wants to manipulate the URL for its refreshes. I wanted to avoid (obvious) roundtrips and have more control over the refresh behavior.
It should be noted that I only had IE 5.5+ (IE6, really) as a target platform, although I usually make reasonable attempts to keep the latest Mozilla happy as well. This is a nice luxury I know and it likely made my solution more workable.
[...blah blah, more explanation how it works...]
The reason I felt I should blog this is that I'm debating internally if I should release my framework to the public, probably via SourceForge. I feel like I need to justify why the world needs another paging framework. I guess I'm unsure if the answer "well, I needed one" is good enough.
I'll keep thinking about it...
