The -X option seems to be interpreted by the Java Virtual Machine.
You can either try to run the application using "java -jar SNMP4J.jar 
[options...]"
or at last resort, rename the -X parameter in the code and recompile it.
I will provide an alternate option name for the encryption passphrase in the
next release.

Take a look at the JavaDoc of the Snmp class for an example.
