I used Spring Roo for a small, public web application recently, and all went well until I attempted to deploy it on a hosted VPS.
The application didn't deploy, and I got the dreaded error message:
java.lang.NoClassDefFoundError: javax/el/ValueExpression
A little poking around led me to this Roo bug report that details the problem. ...

I'm about to start working on an existing web application that has business rules concerning the timelines of processes.
Things like "when X happens, if it's been more than 14 days since Y happened, do Z".
Believe it or not, in the past, this has been integration-tested by doing Y, waiting 14 ...

I'm woking on a "legacy" Java app that's written in Struts and uses EJBs. No Jetty or Tomcat for me - gotta use a "real" J2EE container - in this case, JBoss.

I've seen a lot of articles lately that talk about the nuts and bolts of moving from one J2EE server to another.
I've also seen that a number of companies are struggling with this issue, sometimes even just when upgrading to a newer version from the same vendor.

I got a request from a client for performance-tuning Tomcat.
Typically, I don't really do a lot performance tuning for Tomcat - usually, I front it with Apache HTTPD, and spend most of my performance tuning efforts on the application, not the server.
I got thinking about it, though, and remembered that ...

This morning's general session was the Microsoft keynote.
Microsoft and Sun made a pretty good attempt at trying to convince the crowd the the two companies are friendly competitors, and the interoperability is the highest goal for both. It looks like they may indeed be making inroads in the data center ...

On Wednesday afternoon, I attended the session, "Creating Compelling User Experiences", by Ben Galbraith from Mozilla.
It was a very interesting session, with lots of quotes from user interface luminaries. My favorite was a quote from usability expert Louis C. K. - "Everything's amazing, and nobody's happy".
My take-aways were:

First, an observation - today, I decided to stop lugging my laptop around, and left it at the hotel - I'm fully dependent on the SunRay terminals today - the wireless connectivity left a lot to be desired yesterday, anyway
