Atmosphere GWT sample about atmosphere-samples

[TotalFluke]

I managed to solve my issue. The javascript for atmosphere was missing from the war directory. I used the following maven dependency...

<dependency>
    <groupId>org.atmosphere.client</groupId>
    <artifactId>javascript</artifactId>
    <version>2.3.1</version>
    <type>war</type>
    <scope>compile</scope>
</dependency>

But this did not actually place the javascript in a place where it could be found by my project. I'm not sure it placed it anywhere at all. This is probably because I'm not using Maven correctly. Instead I had to manually add this javascript to the project.

Also, I needed to manually include the javascript in the html file like so...

    <script type="text/javascript" language="javascript" src="javascript/atmosphere.js"></script>

This fixed the problems described in this thread.

I am using 2.3.0-GWT27 with 2.3.0 runtime and still having this problem.

            <!-- Atmosphere -->
            <dependency>
                <groupId>org.atmosphere</groupId>
                <artifactId>atmosphere-runtime</artifactId>
                <version>2.3.0</version>
            </dependency>
            <dependency>
                <groupId>org.atmosphere.extensions</groupId>
                <artifactId>atmosphere-gwt20-client</artifactId>

            </dependency>

Did you solve your problem? I seem to have the same problem as you had.

[ternite]

No, I did not. I was trying to learn about Atmosphere and quit doing so after not being able to apply it in my usage scenario. In case you would want to know my alternative: I did not find one. But I admit I was not intensely looking for it, as it was for educational purposes only.
Maybe @BenDol was more lucky?

[TotalFluke]

I'm also getting this exact same problem, I've tried a range of versions of atmosphere-gwt20-client and it happens in all of them.

Any ideas what else I can try to fix this?

Thanks @TotalFluke. I had same issue and Your solution helped me to :D
I don't know why maven did not copy javascript directory ino /src/main/webapp.

I had to placed it there manually, ther run Development mode from eclipse.
