Java 6 unsigned entry in resource

We are currently upgrading Ignition from 7.8.3 to 7.9.4. It’s working for users with Java 8, but users with Java 6 are getting the following error when trying to start a client:

Unable to launch the application. Found unsigned entry in resource: http://ignition:80/main/system/launchbin/launchclient.jar

These users are not able to upgrade Java due to other legacy applications. What can be done to resolve this issue? At this point I’m not sure if this is a bug in Ignition, a gateway configuration issue or a client Java configuration issue.

Any help would be much appreciated.


Java 6 turned into a nightmare for us. I switched to the Native Client launcher and bundled java with it so there is no system dependency on needing a java install. I push out the client with our corporate software deployment system. Much easier.


You need to use the Native Client Launcher to continue using Java 6.
