Help wanted: java.lang.IllegalArgumentException: No selectors

Closed this issue 7 years ago · 2 comments

Hi,

I'm trying to start Stubby but i'm getting a IllegalArgumentException when doing so.
I tried to parse the YAML file to make sure that it is Stubby-proof, and it seems to work. So that doesn't seems to be the problem.
Can someone please tell me what i'm doing wrong?

    private static final int STUB_PORT = 4200;
    private static final int ADMIN_PORT = 8822;
    private static final String STUB_YAML_LOC = "stubdata.yml";

    public Stubby() {
        startStub();
    }

    public void startStub() {
        try {
            File configFile = new File(STUB_YAML_LOC);
            List<StubHttpLifecycle> list = new YAMLParser().parse(configFile.getParent(), configFile);
            stubbyClient.startJetty(STUB_PORT, ADMIN_PORT, STUB_YAML_LOC);
            LOGGER.info("Stubby successfully started.");
        } catch (Exception e) {
            LOGGER.error("Error while starting Stubby", e);
        }
    }

Hi Robin, 1. What stubby4j artifact are you using - what's the full name of the artifact? 2. Do you have another Jetty binaries on the classpath? 3. What happens if you don't pre-parse the YAML, but just start the stubby: stubbyClient.startJetty(STUB_PORT, ADMIN_PORT, "stubdata.yml"); ? 4. Are you getting this exception when running tests in the IDE?

Hi,

Thanks for your quick reply.
There was a Jetty dependecy on my classpath comming from Selenium. After i excluded that Jetty dependency it started working without any problems.

So, thanks a lot 👍
