Vaadin 7, Atmosphere and Server Push problems

Question

I've started to build a project using the Maven archetype for Vaadin 7.2.4 and am getting a lot of errors thrown up relating to Atmosphere startup issues. As things stand, I won't be able to enable push support which I'd require to use an addon (OAuthButtonPopup). Although there's lots of general chat about Atmosphere, I can't seem to find anything specific to this issue so am wondering if there is an installation/configuration issue on my side, particularly as there seem to be attempts to instantiate some classes relating to Jetty which doesn't seem relevant to my installation.

Current setup as follows: Java 8 SDK, Java EE7 JDK, Idea IntelliJ 13, Vaadin 7.2.4 and Wildfly 8.

Any pointers would be much appreciated.

Error trace on deployment as follows:

Answer 1

For me it looks like there are libraries included in your war package that should not be packed. You might look into your war to see what jar dependencies are included. Maybe some parts of jetty. You could use

mvn dependency:tree

to see where they come from and exclude them if necessary.

And to enable push this wiki page describes all the required steps: https://vaadin.com/wiki/-/wiki/Main/Enabling%20server%20push

Hi Raffael - looks like you may well be right. There appears to be quite a few Jetty-related dependencies included in the build. Looking at the tree, it looks like this is related to changing a line in the archetype pom from "vaadin-compiled" to "vaadin-compiler" (required to get the the archetype to build and compile on first execution - myself and others have flagged this on the Vaadin forums before).I'll try reverting to the original plugin type and see if that resolves the issue. – Kemppe

Answer 2

Following on the previous answers from rustproofFish and Raffael, I was able to fix the error by adding those exclusions:

   <groupId>com.vaadin</groupId>
   <artifactId>vaadin-client-compiler</artifactId>
   <version>${vaadin.version}</version>
   <exclusions>
        <exclusion>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-servlets</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-annotations</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-util</artifactId>
        </exclusion>
    </exclusions>

Answer 3

Thanks for the pointer Raffael - you were quite correct. There were Jetty dependencies included in the build as a result of changing one of the dependencies in the Vaadin 7.2.4 archetype from vaadin-client-compiled to vaadin-client-compiler in order to get the project to build and compile on first run (see posting on the Vaadin forums entitled GWT compiler error - Vaadin Charts using Maven and IntelliJ https://vaadin.com/forum#!/thread/4751650). The erroneous errors in the dependencies tree were as follows:

Changing the pom.xml entry back to vaadin-client-compiled, cleaning and rebuilding resolved the incorrect dependency; Atmosphere now starts without errors/warnings and push functionality appears to be present and correct based on my limited tests so far.

Answer 4

I had a similar error with Tomcat. I fixed the error by adding the following on my web.xml

    <init-param>
        <param-name>org.atmosphere.cpr.asyncSupport</param-name>
        <param-value>org.atmosphere.container.Tomcat7AsyncSupportWithWebSocket</param-value>
    </init-param>
