Apache Geronimo ships with embedded Derby database. The Derby libraries are present in the server repository at <geronimo_home>/repository/org/apache/derby. By default, a Derby database by name SystemDatabase is created and the files related to the database are stored at <geronimo_home>/var/derby/SystemDatabase. Along with that, by default, server deploys a database connection pool over the SystemDatabase with the configuration name org.apache.geronimo.configs/system-database/2.1/car. The name of the database connection pool is SystemDatasource. The configuration artifacts are stored at <geronimo_home>/repository/org/apache/geronimo/configs/system-database. The deployment plan used for database connection pool is as follows.

By default, a JMS resource adapter that connects to embedded activemq message broker is deployed and running in the apache geronimo server. This is an outbound jms resource adapter that configures a connection factory and two message queues. The configuration name of the resource adapter is org.apache.geronimo.configs/activemq-ra/2.1/car. The artifacts of the resource adapter are stored at <geronimo_home>/repository/org/apache/geronimo/configs/activemq-ra. The deployment plan is as follows.

The following is the deployment descriptor of the JEE application client module that looks up an ejb and calls a method on it. The ejb converts the Indian Rupess (Rs.) into American Dollars ($). The client sends a double value which is Indian Rupees to ejb. The ejb returns equivalent American Dollars as double value.

Apache geronimo ships with ActiveMQ message broker and an inbound and outbound JMS resource adapter for the ActiveMQ broker. This sample illustrates deploying and running two MDBs that listen to a jms topic TextTopic. When the web client publishes a message to this topic, the two MDBs receive the message and process it. Because the message is published to the topic, all the configured listeners, in this case the two MDBs, receive a copy of the message. In addition to that, we will also illustrate how to deploy a JMS resource adapter within the application scope. Usually, the resource adapters are deployed at the server scope and can be used by all other applications as well. In this example, a JMS resource plan is embedded in the application deployment plan geronimo-application.xml and deployed while deploying the application archive.

The above pattern is the way how geronimo references various libraries available in the server repository. Any external libraries can also be uploaded to server repository using admin console portlet. After starting the server, click on Console Navigation => Services => Repository to display Repository Viewer portlet. In this portlet, users can upload required third party libraries by providing proper groupId, artifactId and version values for the libraries being uploaded. The activeMQ rar file is also available in the repository as org.apache.geronimo.modules/geronimo-activemq-ra/2.1/rar. Click on this link to get the usage instructions on how to reference this library in other modules.

The web client that look up the connection factory and topic and sends messages is as follows.
