BEA has released a tech preview version of its flagship product, WebLogic Server, the most advanced JEE application server. The new application server has features that make many other envy, as it is able to do the hot deployment of classes.
Experience using the Eclipse Europa Fall using BEA Connector for WebLogic 10.3 shows a very significant increase in time to deploy changes in the Java classes.
One of our project adapted this environment which makes development pretty much faster and enjoyable.
More time for beers and fewer time waiting to deploy...
