Any way to reproduce this?

Our Channel API support is not the best -- we're missing web-sockets support to ease the impl. We'll get web-sockets once we upgrade AS integration to Wildfly8.

@luksa ^^

[chrisritter]

WildFly 8 Beta1 is due in August but the Final isn't due till November. When are you guys planning on upgrading to WildFly?

[alesj]

I'm upgrading as we speak. :-)

[chrisritter]

@alesj any news on channel support?

[alesj]

@chrisritter i just added Channel test to TCK, and @luksa is looking into it why it's failing.

It's now quite trivial to add a new test, due to Arquillian Drone integration, so I encourage you to add one that would expose your issue.

[alesj]

@chrisritter re-implemented ChannelService version is now in upstream master. Can you give it a spin?

[chrisritterc9]

@alesj Be happy to, I'll try it out tonight

[alesj]

@chrisritter any luck?

[chrisritterc9]

@alesj Sorry for the delay on this, ended up spending a lot more time on our internal release last week than I intended.

Tried building channel/common separately but it looks like there are two many changes since Beta 5 to do that any more.

I can and probably should build a very simple chat app for Capedwarf testing.

Yeah, that would be great -- if you hurry, and there are still some issues, we can try to fix them before next release -- which is definitely this week.

[chrisritter]

@alesj Just created a simple chat app... You can pull it from here: https://github.com/chrisritter/simplechat

[alesj]

@chrisritter thanks! Will have a look asap.

[chrisritter]

Any luck?

[alesj]

@chrisritter need to Mavenize the example first. ;-) Will probably do it 1st thing tomorrow morning, EuroBasket atm. :-)

[alesj]

@chrisritter pull-request sent -- for Mavenization + cleanup

Atm I get this error:

[chrisritterc9]

This means the channel presence service is missing: https://developers.google.com/appengine/docs/java/channel/#Java_Tracking_client_connections_and_disconnections

[alesj]

@chrisritterc9 >> This means the channel presence service is missing Hmmm, true.

I'm trying to figure out when and who/what should trigger this post to /_ah/channel/connect | disconnect.

In SDK this is done by LocalChannelServlet, which looks like it's triggered periodically -- command=poll. But I'm yet to see what invokes LocalChannelServlet::doGet with command=connect.

@chrisritter any idea?

[alesj]

Ha, looks like I got it working. :-)

[alesj]

@chrisritter I pushed the fix/impl into upstream. I can send chat msgs from 2 diff browsers. :-)

[chrisritter]

Sweet.
