Hi,

You need to set the Server session. Please check the below code

CreateServerSessionCommand createSerSesCmd = new CreateServerSessionCommand(simpleConnection);

createSerSesCmd.execute();

session = createSerSesCmd.getSession();

assign this session to cmd object i.e. cmd.setSession(session)

Now try to run the code.

Note: Session is nothing but a String variable
