Support for @Push-Annotion?

[stenersen]

Will the @Push-Annotion be supported for UIs? Right now the sample application does not start when i enable Push-Support. In my application (running in Tomcat) the server starts but the scopes get messed up.

[peholmst]

Web-socket based Push is currently not supported, but will hopefully be in the future.

[peholmst]

The problem is also present for CDI: http://dev.vaadin.com/ticket/12464

Please support @Push in the future.
Event @Push(transport = Transport.LONG_POLLING) results in:

java.lang.IllegalStateException: Cannot suspend a response longer than the session timeout. Increase the value of session-timeout in web.xml

Is there any other workaround to get push+vaadin+spring atm?

[LukaszByczynski]

Increase the value of session-timeout in web.xml. Push with Long Polling works with Vaadin and this Spring Addon.

[membersound]

So how long would the timeout have to be? The default (embedded) tomcat timeout is already 30mins. Why doesn't it work with it?

I don't have any web.xml as I simply extend SpringApplicationAwareServlet. How can I set the sessiontimeout in annotation based config for vaadin?

If it'd be in a http context, one could write:
HttpSession session = request.getSession();
session.setMaxInactiveInterval(10*60);

But how in vaadin?

[peholmst]

You can configure the session timeout by adding a server.sessionTimeout property to application.properties. As for why it does not work with the defaults, I have to investigate.

[peholmst]

Apparently, when using Vaadin in Spring Boot, the session timeout it set to -60 for some reason unless you set it explicitly in application.properties. I will try to find out why and make sure it is set to something more sensible. In the meantime, specify a timeout manually in application.properties.

[membersound]

Ok it really works using the property. Thanks for your support!
I can totally live with it, as I would later probably want to define the session timeout myself anyhow.

Hi,

I'm trying to get Vaadin's server push running alongside Vaadin4Spring as well. Being unaware of this issue, I blindly added the dependency to vaadin-push to my gradle build today and added @Push to the UI. Here's the error I'm getting:

o.a.c.AtmosphereFramework [JDK14LoggerAdapter.java:588] SessionSupport error. Make sure you define org.atmosphere.cpr.SessionSupport as a listener in web.xml instead

... well that's pretty much all information I have available right now. I don't even have a web.xml at the moment (never needed one). Any help on this would be much appreciated. Currently I am using Vaadin 7.3.0 RC1.

Thanks,

Alan

DId you try to add server.sessionTimeout to application.properties?

[Alan47]

Hi,

sorry for the late response, was a busy week. Well, the thing is that we do not have such a file so far. Where would that file go? Any reasonable defaults for the server.sessionTimeout?

[peholmst]

I have plans to add a default to the next release (I actually don't know why it is set to -60 when using Spring Boot). In the meantime, add application.properties to the root of your classpath and specify the property manually.

[Alan47]

Hello again,

thank you for your response. I've added an "application.properties" file in src/main/resources", just like in the example you've uploaded. In fact, I just copied your file entirely.

However, I still get the following warning from the atmosphere framework on spring startup:

SessionSupport error. Make sure you define org.atmosphere.cpr.SessionSupport as a listener in web.xml instead

It's only a warning, though. Is that normal, i.e. will it break the functionality of Vaadin Server Push?

[peholmst]

I'm not sure. I have to investigate.

[ghost]

Just to be clear, is 'server.sessionTimeout' not the same as 'server.session-timeout' ? And what are the time units?

[peholmst]

server.sessionTimeout should be the same as server.session-timeout. And the time units is seconds.

[peholmst]

See #169

[peholmst]

See #209 #203

Closing since this is no longer relevant to Vaadin4Spring. Any issues should be reported to the official Vaadin Spring add-on project.
