Faster than Fastest! -- Session Redeployment in GlassFish v3

Redeployment time is one of the metrics we track in our productivity metric (others include startup and deployment time). GlassFish v2 is already very fast - actually, according this survey ran by the ZeroTurnaround folks, GF v2 is the fastest JavaEE compliant container - but GF v3 is even faster.


One of the new features in GlassFish v3 is session state preservation across redeployments. Jan Introduced the new feature during GFv3 Prelude and now Alexis has published a Screencast (movie) using JPetStore (Spring, IBatis, etc). The screencast uses NetBeans 6.7 but it works equally well on the Eclipse Bundle.

Very much looking forward to GFv3 FCS...


Thanks for ur post. Mi check it out

As a quick note, we've had more than 1000 responses to the "Java EE Containers: Heaven or Hell" survey now (the blog post you reference). Since we only referenced the first 700 - we're going to have to update all the information by the end of the month.

So far, we've only seen 2 responses from people using GlassFish v3, and it would be great to see more. The 3 question survey is still live, here:

Hey David, GlassFish v3 is the new generation and v2 remains still by far the most widely deployed version, so I'm not surprised (even if an explicit choice for v3 might have helped gather more data).

Nevertheless GlassFish looks very good in those preliminary results, really really close to Tomcat which in many developers mind is considered the ultimate lightweight. Some might argue that this is because they haven't tried Jetty ;) I'll simply tell them they should try GlassFish v3 (Preview today, final in the Fall).
