Enable Java 7 plugin for Linux Firefox

So the new Java update came out yesterday (version 7.51) and messed up access to our Checkpoint VPN SSL client.  And I find out that after installing the new version on windows you need to set the Java control panel security tab to Medium for our VPN to be trusted.

But I’m using Fedora 19 so there is no Java control panel.  After updating the JDK (because it has everything) and updating all of the alternatives spelled out really well here: http://www.if-not-true-then-false.com/2010/install-sun-oracle-java-jdk-jre-7-on-fedora-centos-red-hat-rhel/

I still can’t access the VPN snx web plugin.  Turns out it’s the same security issue from windows and OS X but I need to find the configuration.  Turns out it’s in you home folder under the .java folder.  Specifically this file /home/<user>/.java/deployment/deployment.properties

[important]In there you need to add some lines.[/important]  Probably not as many as I added but this worked for me and should for you.

#deployment.properties

deployment.modified.timestamp=1389762919697
deployment.expiration.decision.timestamp.10.45.2=1389762919
deployment.version=7.21
deployment.expiration.decision.10.45.2=later
deployment.expiration.decision.suppression.10.45.2=false
deployment.browser.path=/usr/bin/firefox

deployment.expiration.check.enabled=false
deployment.security.askgrantdialog.show=true
deployment.security.askgrantdialog.notinca=true
deployment.security.jsse.hostmismatch.warning=false[/important]

So the refrence for this took me a while to find but it’s located here: http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/properties.html
