When I have to bridge that gap between Spring and non-Spring classes, I
have usually created a Factory with a static getter and a non-static
setter (or use constructor injection). Then, I would wire a bean in
Spring to construct an instance of the factory and call the non-static
setter. The setter would set the value of the static instance element.
Then, you could just call DataSourceFactory.getDataSource() to get the
instance. It saves you from replicating a lot of Spring setup that
already works perfectly. I haven't tried this exact thing in Jetspeed
yet, but I have done it in other similar environments.
Example:
public class DataSourceFactory {
private static DataSource instance;
public static DataSource getInstance() { return
DataSourceFactory.instance; }
public void setInstance(DataSource ds) {
DataSourceFactory.instance = ds;
}
}
Supplementary Spring config (in etc/assembly/override)
<bean id="dataSourceFactory" class="DataSourceFactory">
<property name="instance" ref="JetspeedDS" />
</bean>
Then, DataSourceFactory.getInstance() would return the Spring
"singleton" object for the data source.

Can I access that in a non-Spring class?

To the best of my knowledge, Jetspeed is wiring it via Spring in
WEB-INF/assembly/boot/datasource.xml. The Spring bean is called
"JetspeedDS".

Subject: Accessing Jetspeed Database
I am trying to access the Jetspeed database. There is a jetspeed.xml
file in {tomcat_dir}/conf/Catalina/localhost/. I know Jetspeed can
access the database but I can't seem to get access to it. Does anyone
know how Jetspeed is setting up the database connection? When I try the
following code, I get a naming exception. If anyone knows why that code
does not get the work please let me know ASAP. Thanks!
