JAVA cache at System Level

It could be useful to avoid that each user, on a multiuser operating system, have own java cache under his home directory, i.e. a corporate application used by each user. Every time the jnlpi is upgraded, every user have to download the new version in his home directory cache.

Using system level cache, only the first user launching the jnlpi will download the java application in the cache.


vi /usr/java/jre/lib/deployment.config

deployment.system.config file:/etc/java/deployment.properties

vi /etc/java/deployment.properties

deployment.system.cachedir /var/tmp/java/wscache
deployment.system.security.trusted.certs /var/tmp/java/security/trusted.certs

mkdir /var/tmp/java
mkdir /var/tmp/java/wscache


Warning. There will be problems with write and read permission on such directory...
