Open Source Java Application Servers are dominating the market for Java Application Servers. While proprietary vendors like IBM, Oracle and BEA have wide acceptance, Open Source projects like Apache Tomcat, JBoss, Sun Java Enterprise System and Glassfish make up a significant chunk of the usage. Those are the findings of BZ Research, a division of BZ Media from a survey of Java developers.
