@mikeloukides article Who leads the Java parade? - OReilly Radar asks who will fill the Java leadership void now that Sun is absorbed by article.
However, he misses one of the biggest Java company leaders out there - Red Hat and their JBoss division. Hibernate shaped the JPA JSR. Seam, not Spring, drove the CDI (formerly WebBeans) JSR. JBoss AS 7 and its blazing speed are potential game-changers in the JEE space.
Torquebox while being a JRuby container leverages JBoss AS to provide the some of the fastest Rails hosting out there. Drools is innovating the Rule space. And HornetQ has broken JMS SPEC records .
Infinispan will play a big role in Data Clouds and caching tiers, especially with the addition of Hibernate OGM.
So who leads the Java Parade? Obviously, its the most innovative java company.
