Tynamo-Conversations + Tapestry-Atmosphere
Hi all,
I'm trying to intrgrate tapestry-atmosphere library in my project,
where we already have tynamo conversation and tynamo security.
The following exception is thrown, when I try to broadcast message:
internal.PerRequestBroadcastFilterImpl -

I checked cookies in this request and they are not empty. What could
be the cause of this problem?

I notice from the exception that the error originates from
SecurityComponentRequestFilter
So it sounds like you'll need to contribute a ComponentRequestFilter. Make
sure you order it "before:" the tynamo filter.

I'm not familiar with tynamo security but Kalle has pointed out it uses a
HttpServletFilter to initialise some per thread values.
tapestry-atmosphere uses tapestry-offline to render component events.
Unlike a normal request / response this doesn't go through the
HttpServletRequestFilters etc.
Take a look at the request processing diagram at the bottom of this page
http://tapestry.apache.org/request-processing.html
tapestry-offline invokes the
org.apache.tapestry5.services.ComponentRequestHandler directly.
Looking at the diagram, it looks like you have an opportunity to initialize
the thread by contributing a ComponentEventFilter or a
ComponentEventRequest filter.
If you want to test for an offline request, you can check
OfflineCookieGlobals.isCookiesStored()

I haven't paid close attention to this thread but the securitymanager
certainly isn't accessible. It's perhaps quite understandable that the
security library requires certain request (thread) attributes to exist to
uniquely identify the user, just the same way a persistence framework
requires a session/entitymanager. It's relatively simple to bind the
securitymanager to the currently executing thread, see
https://github.com/tynamo/tapestry-security/blob/master/src/main/java/org/tynamo/security/services/impl/SecurityConfiguration.java.
That said, I'm not sure what would be the best invocation point to make it
happen with atmosphere/tapestry-offline.

I'm sorry for the inconvenience, but there is another exception that I
cannot overcome:
when I turn https on and add secure=true to the container component,
the following exception is thrown:

Seems that SecurityManager is not accessible because of component
"offline" rendering. Are there any solutions to fix it?

Thank you for the reply. Yes, that is the problem for me: I don't know
where to bind SecurityManager.

Great! I'll add an issue to copy the isSecure() flag from the async
request.
> how can I override your "tapesty-atmosphere.js"?
stick it in the right path under WEB-IBF/classes and your container's
classloader will give it precedence.

Thank you, Lance!
Now it works perfectly.
And one more question: I would like to push custom javascript using
atmosphere. I've seen this
https://github.com/uklance/tapestry-atmosphere/issues/5 and my
question is, how can I override your "tapesty-atmosphere.js"?
Thanks,

Hi Sem, it looks like RequestSecurityManagerImpl is trying to redirect the
async request. Obviously redirecting an async request doesn't make sense,
hence the UnsupportedOperationException.
I can only guess that you have the @Secure annotation on the page. Correct?
Ultimately, we want Request.isSecure() to return true so it doesn't attempt
the redirect. I can see two ways of doing this:
1. Override / decorate PerRequestBroadcastFilter. You could extend
PerRequestBroadcastFilterImpl and override
createOfflineRequestContext(AtmosphereResource resource) to call
DefaultOfflineRequestContext.setSecure(true). Luckily this method is
protected so is a couple of lines of code.
2. Override / decorate OfflineObjectFactory such that Request.isSecure()
returns true.

https://github.com/uklance/tapestry-offline/blob/master/src/main/java/org/lazan/t5/offline/services/internal/OfflineObjectFactoryImpl.java
Cheers,
Lance.

Thanks, I just stored Subject in the session and retrieved in the
filter. Not ideal, but ok.
Much to my regret, there are another exceptions: first was with the
not defined tapestry-online symbols and after I defined them I have
another one:

Seems it fails at
org.apache.tapestry5.internal.services.checkForInsecureComponentEventRequest
because the request is not secured, but the page is and tapestry tries
to redirect using OfflineResponse.sendRedirect which throws this
exception

Posted by Lance Java <la...@googlemail.com>.
Youre correct, the HttpServletRequest and HttpServletResponse are not
available. This was a design decision made by tapestry-offline. I guess I
could make this pluggable.
But the Request and Response tapestry wrappers ARE available. Also, the
ApplicationStateManager is available. I felt that these are adequate and
tapestry users should never need the raw http objects.
Can you make do with the Request and Response tapestry wrappers? Do you
actually need the raw http objects? Or just properties from it? If not you
could always create a proxy (not ideal I know).

Yes, this is the right place, but I don't have HttpServletRequest and
HttpServletResponse and I can't initialize security subject like here:
https://github.com/tynamo/tapestry-security/blob/master/src/main/java/org/tynamo/security/services/impl/SecurityConfiguration.java#L51
I've tried to make something like this:
ThreadContext.bind(securityManager);
Subject subject = SecurityUtils.getSubject();
subject.login(new UsernamePasswordToken("default", "default", true));
//this user exists
handler.handleComponentEvent(parameters);
But it causes another exception:
java.util.concurrent.ExecutionException:
org.apache.shiro.authz.UnauthenticatedException: This subject is
anonymous - it does not have any identifying principals and
authorization operations require an identity to check against. A
Subject instance will acquire these identifying principals
automatically after a successful login is performed be executing
org.apache.shiro.subject.Subject.login(AuthenticationToken) or when
'Remember Me' functionality is enabled by the SecurityManager. This
exception can also occur when a previously logged-in Subject has
logged out which makes it anonymous again. Because an identity is
currently not known due to any of these conditions, authorization is
denied.

Atmosphere is a bit of a strange dependency unfortunately. Different
containers and different container versions require different jars. The
table here shows the complexity
https://github.com/Atmosphere/atmosphere/wiki/Installing-AtmosphereServlet-with-or-without-native-support#quick-dependency-reference
So I chose to have a "provided" dependency and let the client decide.
Re: Tynamo-Conversations + Tapestry-Atmosphere
Posted by Daniel Jue <te...@gmail.com>.
Lance, I'm also starting to use your work in my application. I think it's
important to note that your code on github works with
atmosphere-runtime-native 2.1.0-RC2 from Dec 2013. Later versions of
Atmosphere seem to need different dependencies included, and also the
contribute method fails because some method signature in Atmosphere changed
after the version above.
Since we're not using build profiles like in your example, I've had to
manually include
<dependency>
<groupId>org.atmosphere</groupId>
<artifactId>atmosphere-runtime-native</artifactId>
<version>2.1.0-RC2</version>
</dependency>
in addition to
org.lanzan
tapestry-atmosphere
in my POM.

Run "mvn:dependency tree" from the command line and make sure your
dependencies match the table here
http://tapestry-atmosphere.uklance.cloudbees.net/. You might need to
<exclude> a dependency? Not sure.
I had troubles with tomcat and apache on cloudbees and had to upgrade to
http 1.1. Does it work on jetty (runjettyrun plugin?).
Possibly best to ask further questions on atmosphere users list if it's
more relevant there.
Re: Tynamo-Conversations + Tapestry-Atmosphere
Posted by Semen Vishniakov <vi...@gmail.com>.
Yes, the exception is gone now, thank you!
But I have another question now:
The demo and my project work perfectly with cometd long-polling
connection. But when I try to change it to WebSocket, the event is not
triggered. There is no errors or exceptions, in browser console I have
"Websocket successfully opened". I assume that the cause could be
tomcat configuration. I use the 7th version and I've added
atmosphere-runtime-native, atmosphere-compat-jbossweb and
atmosphere-compat-tomcat dependencies.
Any ideas?
Thanks in advance!
Sem.

I've just fixed the issue in tapestry-atmosphere 0.0.4 (tapestry-offline
0.0.2)
Please try with the latest version of tapestry-atmosphere.

Re: Tynamo-Conversations + Tapestry-Atmosphere
Posted by Lance Java <la...@googlemail.com>.
Hi Sem,
Taking a look into this, I was surprised to see that tapestry's request
does not have a getCookies() method
http://tapestry.apache.org/5.3/apidocs/org/apache/tapestry5/services/Request.html
Instead, the CookieSource has to go directly to the HttpServletRequest
https://github.com/apache/tapestry5/blob/a197470fc1e698ca713741150114543a3f30d25b/tapestry-core/src/main/java/org/apache/tapestry5/internal/services/InternalModule.java#L205
Under the hood, tapestry-atmosphere uses tapestry-offline to which fools
tapestry into rendering templates by spoofing a Request and a Response. I
took the design decision NOT to mock HttpServletRequest and
HttpServletResponse but it seems that's now causing an error in Tynamo
I feel that we should add a getCookies() method to
org.apache.tapestry5.services.Request (this would be a breaking change).
If CookieSource could then invoke this it would fix your error.
I'm guessing that Howard has a reason for leaving this off the Request
object?
Another option is for tapestry-offline to override the CookieSource service
but this gets a bit messy.
Cheers,
Lance.
