You may have thought we'd be taking it easy after our big Seam 2.0 release a few weeks ago, but we've been hard at work getting ready for 2.0.1. It's almost ready, so we're releasing CR1 today. (downloadrelease notesdocs)
There has been a couple of interesting blog entries about Hibernate Shards and data sharding / partitioning in the last few days (here and there). Both give a decent five / ten minutes overview of Hibernate Shards.
A robust web application should not crash and die when the session times out. I guess we can all agree on that, but thanks to the stateless nature of HTTP and the usual hacks attaching session state onto that protocol, this is quite difficult to accomplish. Just search for session timeout on Google. So here I am with my JSF/Seam/Ajax4JSF/jQuery application, trying to make it more robust.
Seam offers some basic infrastructure for CAPTCHA creation and validation, so all you have to do if you want to add CAPTCHA validation to a form is add a single form field and show the picture with <h:graphicImage/>. The only built-in implementation we shipped with Seam 1.x and 2.0 was based on JCaptcha, but you could easily extend it and do your own question/answer thing. This is actually what I did and you can see my simplified math question CAPTCHA if you try to post a comment to this entry.
