Below is the testcase setup methhod:

@BeforeClass
    public void bootContainer() throws Exception {
        Properties props = new Properties();
        props.setProperty(Context.INITIAL_CONTEXT_FACTORY,
                LocalInitialContextFactory.class.getName());
        Context context = new InitialContext(props);
        service = (HelloService) context.lookup("HelloServiceLocal");
    }

I get error at line where InitialContext() is created...
