Missing ChannelListenerAsync.java

[diarybooker]

I created one myself:

package no.eirikb.gwtchannelapi.client;

import com.google.gwt.user.client.rpc.AsyncCallback;

public interface ChannelListenerAsync { void onMessage(String message,AsyncCallback<Void> asyncCallback);
void onOpen(AsyncCallback<Void> asyncCallback);
void onError(int code, String description, AsyncCallback<Void> asyncCallback);
void onClose(AsyncCallback<Void> asyncCallback);
}

Hi

Could be a pull request?

Possibly, not quite sure how all that works.... I've never used github before, but I do now have a working version of your code, but I have edited it like crazy trying to get it working, so would have to start again to try to make it neater?!

Thanks MASSIVELY for helping me implement this in my product though, without this project I would never have figured it out!

What did you have to change?

It's been a while since I worked on this project.
Tried running the demo now, and it did not start with the normal mvn gwt:run.
Noticed it was missing target/gwt-channel-api-demo-0.3-SNAPSHOT\WEB-INF/appengine-web.xml, so I tried copying that manually, and had to manually compile, after that the demo works.

Like this:
cp -r src/main/webapp/* target/gwt-channel-api-demo-0.3-SNAPSHOT/
mvn gwt:compile
mvn gwt:run

It's possible I'm not doing it right or something, for a start I don't use Maven, so that might have an effect, but when I tried to compile it initially, it complained that there wasn't a Listener Async and then complained that there was no "onMessage" or "onjoin" defined on the server, beyond that I can't really remember what problems I had...

I have now added a second text box that allows you to subscribe to a second channel, which meant I could test 4 clients at the same time with two separate channels all interacting with the same server, then add a third channel to all 4 screens and have them all be fed by that channel!

I also added a 10 second delay and resent the message with a modifier so I could see asynchronous channel handling too
