It looks like you have a cross-origin issue (localhost:8888 vs localhost:8080), and CORS would help.

[Ignacio Baca Moreno-Torres]

This is a minimal example using CORS https://github.com/ibaca/autorest-streaming-example/blob/master/server/src/main/java/com/intendia/gwt/example/Main.java#L95

Also, in chrome it is quite easy fix it, because it explain what header is required to make it work. Not sure if Firefox errors are as descriptive as chrome.
