Trying to run the webstart remote poller under Java 7u45 or newer fails with the following exception:
java.lang.SecurityException: Missing required Permissions manifest attribute in main jar: http://172.16.14.15:8980/opennms-remoting/webstart/org.opennms.features.remote-poller.jar at com.sun.deploy.security.DeployManifestChecker.verifyMainJar(Unknown Source) at com.sun.deploy.security.DeployManifestChecker.verifyMainJar(Unknown Source) at com.sun.javaws.Launcher.doLaunchApp(Unknown Source) at com.sun.javaws.Launcher.run(Unknown Source) at java.lang.Thread.run(Unknown Source)
The reason is that Java 7u45 started enforcing the requirement that the JAR manifest of an JNLP app have a "Permissions:" attribute. A "Codebase:" attribute may also be required. For our case, I believe the following need to be added to the JNLP JAR:
Permissions: all-permissions Codebase: *
I've been poking at the webstart-maven-plugin and its <updateManifestEntries> property in an attempt to make this happen in the build, but have not gotten it to work so am punting it to a bug issue.
Even after updating the webstart-maven-plugin version to 1.0-beta6, though, the specified attributes aren't making it into the manifest. My Maven-fu just isn't up to this one, what with all the lifecycles and forks and remembering which one to use for the salad.
