1.5 Components of Community Edition<br />
Apache Geronimo brings together technologies from the broader open source community<br />
to support the Java EE stack. For example: Apache Tomcat, ActiveMQ, Tranql, OpenEJB<br />
and so on. Apache Geronimo uses the Apache license, is highly customizable, and is<br />
community-driven. Figure 1.3 shows the components of Community Edition.<br />
Figure 1.3 – Components of Community Edition<br />
In the figure you can see that Community Edition is composed of the following:<br />
• Apache Geronimo kernel, which provides a framework for adding other services like<br />
the custom business services;<br />

don’t have to worry about any custom integration work or version compatibility issues.<br />
• Administrator console, powerful tool that allows developers to define Tomcat<br />
connections (HTTP, HTTPS, AJP), database pools, and security realms <strong>with</strong>out any<br />
coding or restarting the server.<br />
