Java EE 5 Development Waiting on Vendors
twofish writes "Java EE 5 was a major update and most of the major application server vendors
do not yet have compliant versions released. Dr.
Dobb's reports that this is delaying most solution providers from developing
products based on it, as their customers are not ready for them. However there
is some significant movement among the big players. Among the major vendors,
Sun has released support, WebLogic is close with JBoss following soon after.
Oracle has not announced a road map and IBM is lagging significantly behind,
with full support not due until 2008."
Why switch? If you need a feature from 1.5 or 1.6 then upgrade. Many server side applications of Java have absolutely no reason to upgrade. Most companies will be using 1.4 for many years.
There are significant upgrades on the rich client side for 1.5 and 1.6 especially in the Look and Feel area. My 1.6 apps in GTK look just like a native app, thus I use 1.6 for on the client side. I still however use 1.4 on the server side since there are no performance benefits for my applications. Nice thing about java is everything is byte code compatible downstream. I am sure there are providers out there who still use 1.3 on the server side.
Are you intolerant of intolerant people?
