A subsystem can be mounted, that is, its existence can be declared to the main server. To
mount a subsystem, use the ChildApplicationContextFactory bean. This is an
object that wraps the Spring application context that owns the subsystem and its beans. It
initializes its application context as a child of the main Alfresco Community Edition context with an appropriate
PropertyPlaceholderConfigurer that will expand its configuration
instances that you define should extend the
abstractPropertyBackedBean definition. The identifier that
you define for the bean automatically becomes the subsystem category and
defines where the factory will look for configuration files, in the search
Open the core bootstrap-context.xml file
(the file that controls the startup of beans and their order).
Locate the following bean definition:
<!-- Third party transformer Subsystem -->
<bean id="thirdparty" class="org.alfresco.repo.management.subsystems.ChildApplicationContextFactory"
The autoStart property is set to
true, meaning that the child application context will be refreshed
when the server boots up, activating the beans it contains. For
subsystems containing background processes or daemons (for example,
the file server subsystem), it is very important to set this property,
otherwise the subsystem will never activate.
Save your file.
