You can develop a custom thread identity service class by implementing the
com.ibm.wsspi.kernel.security.thread.ThreadIdentityService
interface that is
provided in the Liberty server. The
ThreadIdentityService
interface is a Service Programming Interface (SPI) that
enables support to receive notifications of user identity switches.
Procedure
-
Create a custom thread identity service by implementing the
ThreadIdentityService
interface.
-
Convert the implementation class into an OSGi service.
You can do the conversion in either of two ways:
-
Convert your
ThreadIdentityService
class into a Declarative Service (DS)
component.
-
Write a new
ThreadIdentityService
class that is a DS component and delegate it
to your ThreadIdentityService
class. Register your
ThreadIdentityService
class directly in the Service Registry (SR) by using the OSGi
core APIs.
-
Package the custom thread identity service as an OSGi bundle and export the
ThreadIdentityService
service.
-
Create a feature manifest to include the OSGi bundle.
-
After the feature is installed into the user product extension location, configure the
server.xml file with the feature name.
