Your code should read:

I am trying to add a stopvm method to clienttest.java in the jax-ws sample directory of the sdk. I understand that to power down a vm I need to call the powerDown() method from the console object that is created as an attribute of the session object when the openExistingSession() method is called. However when I try and compile the following example Java cannot find the session objects console attribute.
