How ready are Websockets?

werrenmi Sep 16, 2013 4:32 AM

Hello together

I try to switch from Coment to websockets. We use the JBoss EAP 6.1.Final (APR installed) and Errai 2.2.0.Final at the moment (migration to 3 is scheduled)

Unfortunately i found some problems. The JBossAS7WebSocketServlet imports not existing frame classes (for me a local build from Errai sources has also failed because those imports). As workaround i tried to copy the whole class code into a own servlet and fix those imports.

When i now try to switch the web.xml configuration to websockets like mentioned in the documentation (except i use my own websocket servlet instead), it results in a strange behavior. From time to time i have to reload the page more than one time to see the entire view. But in the Firefox console or in dev mode no error / exception appears, the websocket connection seems also to be successful established. Also in the server log i see only the entries about the websocket protokol and extension. The very confusing thing comes know. In our application the first view is a login mask. The login RPC execution seems to work. For the next view a list of Dto's has to be loaded via a further RPC and here the queue session id locks like lost.

Here is the stack trace:

Hi Michel,

The support for websockets is still experimental I think. Maybe when the official api is ready. The classes that you miss are in this dependency:

    <dependency>
      <groupId>org.jboss.as</groupId>
      <artifactId>jboss-as-websockets</artifactId>
      <scope>provided</scope>
    </dependency>

They are included in the pom, what I do read it that it is not supported on JBoss AS 6 as the name of the servlet also implies, there is also a commit from Mike Brock from 24-2-2013 that saids that it's no longer supported. So my suggestion would be to try and update to an higher version of Errai and JBoss AS to see if that fixes the problem.

Cheers,
       Erik Jan

werrenmi Sep 13, 2013 5:40 AM (in response to edewit)

Hello Erik

Yes of course, i already have seen this dependency, but in the JBoss7Websocket servlet the frame classes are imported for the package "org.jboss.as.websockets", but the correct package of the frame classes in the jboss-as-websockets dependency is "org.jboss.websockets.frame". Because that, this will end in a compiler error for me when i try to build Errai from sources.

I use JBoss EAP 6.1.Final, thats based on JBoss AS 7.2.0.Final.

I think so, to continue an own implementation makes maybe no sense when a standardized API comes with JEE7. Unfortunately this maybe comes too late for our first release, because the target is January of 2014. Maybe this issue: [#ERRAI-527] Resolve websockets to be no longer dependend on Alpha's - JBoss Issue Tracker solves this. Otherwise we should do the first release with Comet and switch in a later release to websockets.

Michel

edewit Sep 13, 2013 8:06 AM (in response to werrenmi)

Hi Michel,

We have a continues build and all our code builds from the source the package of the Frame class is "org.jboss.as.websockets" and it's included as such. Maybe see that you have a fresh checked out project and try to build again?

Ahh sorry about the confusion over which version of JBoss you are using, but with that version it should work.

I've tried it myself and I couldn't reproduce the connection problems that you are experiencing could you maybe send a small project setup so that we can reproduce the problem and see what is going on?

Hello Erik

Sorry for my late reply.

The missing package was really a strange import problem.

I have attached a test project. I can not exactly reproduce, the behavior is different from start to start of the AS. Also reloading of the page few time can help. When i try in the dev mode, no error was shown in the log, only in the firebug console an error occur after ~10 sec with the message "Firefox can't establish a connection to the server at ws://localhost:8080/websockets-test/in.erraiBusWS"

I tested it with a maintained JBoss AS 7.1.1.Final (Replaced jbossweb module), but also with an original JBoss EAP 6.1.Final with installed APR on Linux Mint. As browser i have used Firefox 23.

I hope this help

5. Re: How ready are Websockets?

edewit Sep 16, 2013 5:22 AM (in response to werrenmi)

Hi Michel,

What I notice is that the port is wrong, errai starts a separate server to handle the websockets and that defaults to port 8085. I added this property in my ErraiService.properties

errai.bus.web_socket_url=/errai-tutorial/in.erraiBusWS

so in your example that should be /websockets-test/in.erraiBusWS

also to see if the connection is established you can type errai_status() in your webbrowser console.

Hope that helps,

werrenmi Sep 16, 2013 7:42 AM (in response to edewit)

Hello Erik

As i understand, there are two possible websocket connectivities. One with the separate websocket server and on the other side the servlet. As i know the port 8085 is used as default for the separate server. But when to work with an additional websocket servlet, this separate websocket server is not started since the websocket processing will be done through this additional servlet, or i am wrong?

edewit Sep 16, 2013 8:18 AM (in response to werrenmi)

Hi Michel,

Yes you are right my configuration was trying it in both ways at the same time. So I retried and with just the servlet I get a 405 on all requests. I'll do some more investigation why that is. When I run a errai_status() it seems that my bus remains in a state of trying to connect. But with the separate server it seems to work, maybe you can try that as well?

8. Re: How ready are Websockets?

werrenmi Sep 16, 2013 8:37 AM (in response to edewit)

Hello Erik

I think you try on JBoss EAP 6.1.Final? The reason for the 405 is the missing APR installation. Here is the manual to install it: JBoss Web - Apache Portable Runtime and JBoss Web

With the separate server i can establish the connection as well, but as i understand, this server doesn't run in the AS Servlet Container, and therefore the scopes on the services doesn't work properly. In our application the login service has an injection point for that the corresponding injection target is javax.enterprise.context.SessionScoped scoped. Here i get the following exception:

14:35:14,703 ERROR [org.jboss.ejb3.invocation] (pool-15-thread-1) JBAS014134: EJB Invocation failed on component SecurityServiceImpl for method public abstract ch.apkern.achilles.apisecurity.client.session.ClientSessionDto ch.apkern.achilles.apisecurity.service.SecurityService.getClientSessionDto(): javax.ejb.EJBException: org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active contexts for scope type javax.enterprise.context.SessionScoped

Hi Michel,

One thing that you could try is to update to 2.3.2.Final there have been a lot of bug fixes and that is the most stable version with regards to the bus. I must admit that we haven't tried websockets for a while and like I said before it's very experimental. There could be support for CDI in the separate server implementation.

werrenmi Sep 17, 2013 9:55 AM (in response to edewit)

Hello Erik
I tried 2.3.2.Final, but the same behavior.

I looked a bit into the code and maybe found at least one problem with the Sec-Websocket-Protocol header param. In the class org.jboss.errai.bus.client.framework.ClientWebSocketChannel, the handshake will be started without defined protocols. On the other side, the org.jboss.errai.bus.server.servlet.JBossAS7WebSocketServlet defines the "J.REP1.0/ErraiBus" protocol. The error information in Firebug was very poor, but Google Chrome brings up this error exactly. I have checked out the 2.2.0.Final tag and recompiled with an equivalent protocol on both sides and it works.

But now, the handshake is very slow (over 20 sec).

Is it scheduled, to fix the Websocket implementation?

Hi Michel,

     I'm using Errai 3.0-SNAPSHOT. Is there good documentation on how to implement WebSockets in JBoss AS ? I'm following this: http://docs.jboss.org/errai/3.0.0.20140214-M4/errai/reference/html_single/#sid-53380177 but JBossAS7WebSocketServlet is not being resolved, same thing with WebSocketServlet.

     Were you able to solve this?

Thanks!
