JMX - Skeleton Error

[cht47]

Hello,
I want to monitor some values of our backend software (tomcat).

I've installed the Java-Gateway and configured everything. Now I get the following exception:

java.io.IOException: Failed to retrieve RMIServer stub: 
........
skeleton class not found but required for client version

I talked to our head of R&D and he told me that we are not using any stubs or skeletons and I should set the option:

java.rmi.server.ignoreStubClasses=true

in the client.

But where can I add options to the Java gateway (except the conf file)? I've installed it on Ubuntu 16.04 via repository. The server and gateway runs on the same system.

Thanks in advance.
