If you find yourself demonstrating the Fedlet (and, let's face it, who doesn't?), you should find this script useful. Assuming you've deployed OpenSSO to Glassfish via the autodeploy directory and created and deployed the Fedlet, it undeploys both, restarts Glassfish (not that you should really need to, but it's good to start from a safe, known base) and removes the OpenSSO and Fedlet configuration directories. Now you'll be ready to go round the loop again, without any JavaOne 2008-style hiccups
Anyone working with OpenSSO and/or Glassfish might find some aspects of the script useful; particularly the way it waits until the apps are undeployed before restarting Glassfish. Autodeploy is one of my favorite Glassfish features. Here's the output from the script:
pat-pattersons-computer:~ pat$ ./reset.sh Undeploying the fedlet..Done Undeploying OpenSSO........Done Domain domain1 stopped. Removing Fedlet config directory Removing OpenSSO config directory Starting Domain domain1, please wait. Log redirected to /Applications/NetBeans/glassfish-v2ur2/domains/domain1/logs/server.log.
