Clustered Session Management: Inifinspan

Configuring Embedded Inifinspan Clustering

When using the Jetty distribution, you will first need to enable the session-store-infinispan-remote module for your Jetty base using the --add-to-start argument on the command line.

$ java -jar ../start.jar --create-startd
INFO : Base directory was modified

$ java -jar ../start.jar --add-to-start=session-store-infinispan-remote

INFO : Base directory was modified

Doing this enables the remote Infinispan Session module and any dependent modules or files needed for it to run on the server. The example above is running an fresh ${jetty.base} with nothing enabled. Because Infinispan is not a technology provided by the Eclipse Foundation, users are prompted to assent to the licenses of the external vendor (Apache in this case). When the --add-to-start argument was added to the command line, it enabled the the session-store-infinispan-remote module as well as the sessions and server modules, which are required for Infinispan session management to operate. It also downloaded the needed Infinispan-specific jar files and created a directory named ${jetty.base}/lib/infinispan/ to house them. In addition to adding these modules to the classpath of the server it also added several ini configuration files to the start.d directory of the ${jetty.base}.

Note

If you have updated versions of the jar files automatically downloaded by Jetty, you can place them in the associated ${jetty.base}/lib/ directory and use the --skip-file-validation=<module name> command line option to prevent errors when starting your server.

Opening the start.d/session-store-infinispan-remote.ini will show a list of all the configurable options for the JDBC module:

# ---------------------------------------
# Module: session-store-infinispan-remote
# Enables session data store in a remote Infinispan cache
# ---------------------------------------
--module=session-store-infinispan-remote

#jetty.session.infinispan.remoteCacheName=sessions
#jetty.session.infinispan.idleTimeout.seconds=0
#jetty.session.gracePeriod.seconds=3600
jetty.session.infinispan.remoteCacheName
Name of the cache in Infinispan where sessions will be stored.
jetty.session.infinispan.idleTimeout.seconds
Amount of time, in seconds, that the system allows the connector to remain idle before closing the connection.
jetty.session.gracePeriod.seconds
Amount of time, in seconds, to wait for other nodes to be checked to verify an expired session is in fact expired throughout the cluster before closing it.

Configuring Embedded Inifinspan Clustering

During testing, it can be helpful to run an in-process instance of Infinispan. To enable this you will first need to enable the session-store-infinispan-embedded module for your Jetty base using the --add-to-start argument on the command line.

java -jar ../start.jar --add-to-start=session-store-infinispan-embedded
