------------------------------------
Summary: Support session replication through OSGi 6 http whiteboard
Key: KARAF-4685
URL: https://issues.apache.org/jira/browse/KARAF-4685
Project: Karaf
Issue Type: Improvement
Components: cellar-http
Reporter: Roland Hauser
Currently, session replication can only be done through specifying the
Hazelcast filter/listener in the web.xml file of a web-application. This can be
a serious disadvantage if you also want to install a web-application to another
web-container which does not need clustering, and, consequently, does not
contain the Hazelcast libs. In this case, the application won't start.
I suggest an additional way how session replication could be realized without
the need of modifying the web-app: it could be done through a Cellar component
which implements a http whiteboard. I would realize this as follows:
- Register a Filter/Session listener to the OSGi service registry. Per default,
every web-application installed is considered for session replication.
- It should be possible to configure Hazelcast filter properties either through
a config file inside the OSGI-INF folder of the web-app, or, through the
ConfigAdmin service.
- If the sessions of a specific web-application should not be replicated, then
this could be flagged either through a config file inside the OSGI-INF folder
of the web-app, or, through the ConfigAdmin service.
What's your opinion?
