The GlassFish WebTier Web container features are very extensible, modular, easy to use, and adaptable — while offering comparable performance is part of the Sun GlassFish Enterprise Server. With support for clustering, persistence, and messaging, just to name a few, as well as enterprise-class service and support from Sun and the backing of a large and thriving community, Sun GlassFish Enterprise Server is a superior alternative for those who wish to move beyond Web-tier application development. With GlassFish there is a clear, straightforward way to take advantage of technologies such as Enterprise Java Beans (EJBs), the Java Persistence API (JPA), Java Message Service (JMS), and other capabilities.
This white paper, Learning GlassFish for Tomcat Users, demonstrates that the Web container capabilities provided by GlassFish offer superior extensibility, scalablity, and usability compared to those of Tomcat—without sacrificing performance.
