Answer 1

The problem is that you are explicitly creating the properties and passing them into the InitialContext constructor. This means the jndi.properties on the class path won't be read.

Your code should be something like:

Context context = new InitialContext();
ConnectionFactory connectionFactory = (ConnectionFactory) context.lookup("ConnectionFactory");
Queue queue = (Queue) context.lookup("MyQueue");

Answer 2

You can set static properties as well as retrieve them from a file as such:

    InputStream is = getClass().getResourceAsStream("/my.jndi.properties");
    Properties jndiParameters = new Properties();
    jndiParameters.load(is);
    jndiParameters.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.activemq.jndi.ActiveMQInitialContextFactory");
    jndiParameters.put(Context.PROVIDER_URL, "tcp://localhost:61616");
    Context ctx =  new InitialContext(jndiParameters);
...

This works as long as you set the static props after you load the resource. Helpful if you're loading the provider url from somewhere else for instance.
