Apache TomEE Certified Web Profile Compatible

Leia em Português


Yesterday at JavaOne, the Apache Software Foundation announced the availability of Apache TomEE, the Java EE 6 Web Profile certified stack consisting of Apache Tomcat, Apache OpenWebBeans, Apache MyFaces, Apache ActiveMQ, Apache OpenJPA and Apache CXF. Formerly referred to as Apache Tomcat + OpenEJB, it has been renamed to Apache TomEE to signify the inclusion of the other Java EE implementations.

Apache TomEE joins other open-source Java EE implementations, such as GlassFish, JBoss and Apache Geronimo, and is one of only six certified JavaEE engines. Advantages of Apache TomEE include:

  • Size: the entire Web Profile is only 24Mb
  • Memory usage: very little required, and passed the TCK wtihout having to increase memory allocation from the default
  • Agility: the server can go through a start/deploy/test/undeploy/stop cycle in 2-3 seconds, when run in embedded mode
  • Open source implementation running on existing Apache projects

Its small size and embeddability makes it ideal for running in cloud environments, where it is often the case that there are large numbers of small systems rather than few large instances. It has alread been certified on Apache's EC2 t1.micro, m1.small and m1.large 32-bit images, with 64-bit certification a goal for the near future.

Information on Apache TomEE can be found from the Apache OpenEJB's project page at It is currently in beta release, available for immediate download.

  • Resin OpenSource and Resin Pro

    by Richard Hightower,

    Resin provides an OpenSource version of their Java EE Web Profile app server. It is open source. It was the first implementation outside of Oracle that was certified as Java EE Web Profile compliant.

    Resin Pro provides clustering, session replication, a health system, native HTTP and more. It gets used by some large trading systems, stock markets, some large SaaS providers, network appliances, etc. I used Resin for the first time in 2001. I have been a fan ever since.
