Everything works on Windows and list all output event adaptors which I created. But when I do the same on Linux it didn't show list of adaptors and show error mentioned above.

Youngoo,

WSO2 CEP 3.1.0 is well tested in Linux environments. Specially above scenario is a basic flow in CEP. Can you please let me know in which OS version, you observed above issue.. Are you using JDK 6 or 7 (Jdk 8 is not a supported jdk for CEP 3.1.0)
