Re: dwr java chat demo in t5
You would do this by the topic (eg: "/chat/user1"). You can add custom Authorizers for topic security.
Re: dwr java chat demo in t5
Lance, thanks again, i will check the docs. Seems that longpolling or jsonp is supported best by servers and browsers. The first question i will have if there is a kind of client identification built in. The chat messages must be propageted to the correct users and not to all users. Is a client identification part of the project or does this completely depends on my own businesslogic?

Re: dwr java chat demo in t5
The supported browsers section on the atmosphere page can be ignored as this refers to atmosphere.js which is not used by the cometd integration. Only the supported servers section is relevant. Best to check the cometd docs for supported browsers at www.cometd.org
Re: dwr java chat demo in t5
tapestry-cometd is built using the cometd integration in atmosphere. Atmosphere supports a variety of push mechanisms including WebSockets, Server Side Events (SSE), Long-Polling, HTTP Streaming (Forever frame) and JSONP. Out of the box, tapestry-cometd is configured to use org.cometd.websocket.server.WebSocketTransport but this can be configured in your AppModule ( https://github.com/uklance/tapestry-cometd/blob/master/src/main/java/org/lazan/t5/cometd/services/CometdModule.java#L54 ) The supported servers and browsers are listed here: https://github.com/Atmosphere/atmosphere/wiki/Supported-WebServers-and-Browsers Some more docs here https://github.com/Atmosphere/atmosphere https://github.com/Atmosphere/atmosphere/wiki/Getting-started-with-Cometd https://github.com/uklance/tapestry-cometd/wiki/Configuring-the-CometD-Servlet http://cometd.org/
Re: dwr java chat demo in t5
Hi, Lance, wow, thank you for pointing me to your project! Integration is more than easy, your example works outofthebox in my browsers. I had to install jetty7 support, seems that jetty6 does not support websockets. What are the disadvantages of websockets compared to ajax? I think not all browsers support websockets? Especially the older versions? But i think that all the major browsers support that in their latest versions? I did read that the t5 team want to integrate push, but did not see how this is scheduled. So i want to go with your project. Thanks again, Lance!

Re: dwr java chat demo in t5
Hi, as a previous dwr committer myself, I was keen to provide dwr reverse ajax / tapestry integration. After speaking to the dwr team, I found that the push mechanism in dwr was not considered bulletproof and was directed towards cometd For this reason, I have created tapestry-cometd, a push library for tapestry that requires zero javascript https://github.com/uklance/tapestry-cometd You must be aware that the tapestry team currently have push as a high priority feature for the next release. So watch this space for an out of the box solution. In the meantime, I'll be happy to help with a tapestry - cometd solution .
dwr java chat demo in t5
Hi @all, i was suprised that t5 does not support reverse ajax ;-( googleing around, the only thing mentioned often enough is dwr and i ended here: http://apache-tapestry-mailing-list-archives.1045711.n5.nabble.com/Implement-chat-function-td5606481.html Actually, i want to do the same thing as the threadstarter: A loggedin user can start a one-to-one chat with an admin. The admin can handle multiple chats at the same time... I don't really know if dwr is what i really want and if dwr is the best thing recommended? Or are better solutions out there? So i've tried to integrate the Java Chat with the latest dwr-RC3 from dwr first, but only with partial success. My implementation does not have the same behaviour like the demo: http://directwebremoting.org/dwr-demo/reverseajax/java-chat.html I've put the HTML source (i had to replace the div with an ul) and the Javascript source into a .tml and the Java source into a corresponding java class into my t5 jumpstart project. GOOD: i can see the clients polling: ... [INFO] log.accessLog Incoming request: /dwr/call/plainpoll/ReverseAjax.dwr [INFO] log.accessLog Incoming request: /dwr/call/plainpoll/ReverseAjax.dwr [INFO] log.accessLog Incoming request: /dwr/call/plainpoll/ReverseAjax.dwr [INFO] log.accessLog Incoming request: /dwr/call/plainpoll/ReverseAjax.dwr ... GOOD: the addMessage() Method is called when the button is pressed ok, this is default behaviour GOOD: with opera i first get the expected behaviour: open page in opera and firefox, type "opera1" in opera and the message will be displayed in firefox and opera correctly. NOT GOOD: Then i type an "opera2" in opera and in opera i see the correct output: opera2 opera1 But in firefox, the first message did not disapear, i get: opera1 opera2 opera1 BAD: now i type "firefox" in firefox and i get in opera: opera2 opera1 firefox opera2 opera1 In the firefox browser nothing happens... the textfield is not reset and i still have: opera1 opera2 opera1 BAD: when i now type an "opera3" in opera, i get in opera: opera3 firefox opera2 opera1 initially what i did really expected, but before was the wrong output, which is now replaced with the correct output :-) In firefox still everythig is wrong: opera1 opera2 opera1 opera3 firefox opera2 opera1 VERY BAD: i get a lot of: 2013-05-22 22:28:47.976:WARN::header full: java.lang.NullPointerException and: 2013-05-22 22:28:47.976:WARN::header full: java.lang.IllegalStateException: last? and i don't know anything about these message, from where they come and what they mean and how i can trace them Also with chrome i am facing similar issues to firefox. I know the most questions will come, when i want to access tapestryservices later, but when i get these strange behaviour i don't know if dwr is the right thing when i don't get this simple example running. The thing is that i don't really know what the clients are calling. They call the dwr-servlet via the generated .js: "return dwr.engine._execute(p._path, 'MyChat', 'addMessage', arguments);" but how does dwr response? In the end i must access a t5 service, so the response must be filled with data from the t5 service... At this point i can not imagine how i can encapsulate dwr with t5 and let dwr interact with t5. Informations and examples are more than rare :-( A reverse ajax chat-webapp is not the most extreme case i can imagine :-) Anybody out there with some suggestions?
