What fun we had at LAMS.
The really critical bit that Chuck missed before:
./kernel/component/src/java/org/sakaiproject/component/kernel/component/ContextLoader.java
public class ContextLoader extends
org.springframework.web.context.ContextLoader
{
protected ApplicationContext loadParentContext(ServletContext servletContext)
throws BeansException
{
// get the component manager (we know it’s a SpringCompMgr) and from that the shared AC
ConfigurableApplicationContext sharedAc = ((SpringCompMgr) ComponentManager
.getInstance()).getApplicationContext();
return sharedAc;
}
}
./kernel/component/src/java/org/sakaiproject/component/kernel/component/SpringCompMgr.java
public class SpringCompMgr implements ComponentManager
public synchronized void addChildAc()
{
m_childCount++;
}
public synchronized void removeChildAc()
{
m_childCount–;
// when we get back to 0, close our AC
if (m_childCount == 0)
{
close();
}
}
