Open source Java EE application Server

Java EE application servers are available for enterprise-class Java application deployment, with JBoss, Tomcat, and Apache Geronimo being the most mainstream open source Java EE application Server today.

The following table compares the features of the JBoss 4.2, Tomcat 6, and Geronimo 2 application servers in a comprehensive way: (the "partial support" statement used in the table indicates that the application server is not fully supported and requires some additional packages.) The "in-principle support" statement indicates that the application server requires the support of a third-party installation package. ）

Geronimo 2 is closest to Java EE 5. The Tomcat 6 itself is a lightweight solution, so it does not include all the features of Java EE 5, but it has less memory footprint and runs faster than the other two types of servers.
Description

1, Sun's Java EE 5 standard is an industry standard, and as the implementation of this standard, open source Java EE 5 Application server should be consistent with its best;

2. EJB (Enterprise JavaBeans) refers to Java components that can be deployed on Java EE servers. It usually packages some business functions into reusable components;

3. JSF (Java Server Faces) is a component-based architecture deployed in Java EE applications that provides a basic web development user interface, and JSF uses a component-driven model;

4, the customer-based plug-in support, it means that the original application server functions on the basis of the development of new functions, and can be well coordinated use;
