I am about adding Vaadin framework to my jira plugin.
I have mapped my Vaadin servlet in servlet module in attlassian-plugin.xml

<servlet name="Jira Mobile Actions Servlet" key="jira.mobile.servlet.actions" class="com.atlassian.jira.mobile.servlet.MobileActionsServlet">
        <url-pattern>/actions/*</url-pattern>
        <url-pattern>/VAADIN/*</url-pattern>
        <init-param>
            <param-name>UI</param-name>
            <param-value>com.atlassian.jira.mobile.ui.EditUI</param-value>
        </init-param>
</servlet>

But the problem is where vaadin trying to load his resources js file.
In browser, this js file content looks like this: http://skrinshoter.ru/i/221118/PZnZQuwE.png
When i am wrong?
