Jetspeed uses two Spring containers in the Jetspeed Engine. The first container is the Bootstrap container. It contains all database-related Spring components. The second container is the general Jetspeed container. It contains all other Jetspeed components. The main file configured in the bootstrap is the datasource.xml file.
The Database can be configured in two modes either via JNDI or directly with JDBC and DBCP connection pool datasource.
When configuring with JNDI, Jetspeed does not handle the management of the JDBC data source. The data source and database connection pooling is handling usually by an application server, such as Tomcat or Websphere. With Spring, we configure a JNDI bean by JDNI name, and match that with the Tomcat or Websphere JNDI resource configured in the application server.
<bean id="JetspeedDS" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="resourceRef"><value>false</value></property>
<property name="jndiName">
<value>java:comp/env/jdbc/jetspeed</value>
</property>
</bean>
This method is the default configuration for Jetspeed. This allows the application to manage the database connection pool and possibly use with JNDI resource in other web applications
There is a second bean, commented out, in the spring datasource.xml. It has the same name as the JNDI-based implementation. So you can't use both of these beans at the same time. You must choose one, and comment out the other. With the JDBC/DBCP (Database Connection Pool) configuration, we setup the database connection directly in the Jetspeed web application. We also set up the four standard JDBC connection properties here:
<bean id="JetspeedDS" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close"
>
<property name="driverClassName"><value>com.mysql.jdbc.Driver</value></property>
<property name="url"><value>jdbc:mysql://localhost/j2test</value></property>
<property name="username"><value>j2</value></property>
<property name="password"><value>XXX</value></property>
</bean>
