Additionally the JSF AJAX stuff seems very easy to get up and running
when you have a JSF application already.

Can you comment on the performance of JSF?

I found the performance of JSF in the MyFaces implementation from Apache quite fine, but we did not do a large scale performance analysis as this is not currently running with a large number of concurrent users.

It most likely needs attention since it serializes the state between request (for scaling I believe), but for my usage it was very nice. The abstractions in the tables helps enormously when you need to e.g. add a column to an existing complex table.

I also found that there was an extension (updateSomething) which allows you to update the target context with information in the current context when following a link. That is extremely useful in decoupling parts of the application - you only transfer the key values needed.

Have you tried the NetBeans Visual Web Pack, which builds on it and adds to it?

We are an Eclipse shop so I have briefly looked at Netbeans but at that time we did not have the need for that. We have a very plain design and I carefully and loving handcraft the code, so using GUI-stuff is not yet.

I was very interested in hearing Ed Burns talk on JSF with Ajax at JAOO last year, and I would believe this to be production quality today.

Is anybody using this on the '400? or on another web server using the '400 as a data store?

We are getting into letting the AS/400 do some of the heavy lifting in web applications based on Jetty and Tomcat with Resin waiting on the side. We are standardizing on executable jar-files and have learned that everything deployed to the AS/400 must be unpacked before hand to allow the JVM to cache work done.

We have not yet deployed JSF-applications on an AS/400, but we run web applications in production.
