Re: [appengine-java] Re: Channel API (Java) doesn't work locally, but in production mode.
FINALLY! We were able to fix the problem :) First of all we migrated to 1.5.0 Then we noticed that the exception I mentioned in my last post was caused by some jar files in the target folder, namely: appengine-api-labs appengine-api-stubs appengine-testing So we excluded those jars from being compiled into the target folder (we only need them for local unit testing.) After this steps were made the channel was finally working. Moishe, thanks for your help :) Kind regards, Z On Thu, Jun 16, 2011 at 5:18 PM, Zerot Samsa zerotsa...@gmail.com wrote: Well... i've tried simplyfing the channelId, but that didn't solve the problem So we migrated to version 1.5.0.

-- can you try with 1.5.0?
Basically the logic that's happening here is:
- the application calls create channel
- the dev appserver gins up a token consisting of a random string
plus the application-provided client id
- the dev appserver adds this token to a hashmap of token - clientid
- the dev appserver returns the token
Later, when the client connects, this happens:
- the client makes a post to /_ah/channel/dev?
command=connectchannel={{token}}
- the dev appserver intercepts this request and looks up the
channel query param in the hashmap of token - clientid
What seems to be happening in your case is that the dev appserver
can't extract the channel query param based on the application key
is null error. All I can think of is that there's something in the
token that's preventing the query params from being parsed correctly.
As a test, can you try simplifying your client id? (I can't read the
whole thing because Groups thinks it's an email address and elides it)

Re: [appengine-java] Re: Channel API (Java) doesn't work locally, but in production mode.
Yes, that's the value returned by ChannelService.createChannel(channelId), where channelId is the email address of an user, which explains the @. Should we use something else as the client id and/or remove all special characters of the clientId? Thanks.
