Seesion is Expired.click here etc...
It is coming vert frequently.
how to overcome this problem

I think the session timeout has to be configured individually for your servlet-container. Just look up the manual for it. Otherwise there is an add-on here called SessionGuard. Give it a try, perhaps it helps you!

Hi Vamshi,

Marc is right, check your web.xml and change your session-timeout (or add it if you don't have it configured), in other case the session timeout would be the container configured.

The web.xml should look like:

<web-app id="WebApp_ID">
    <display-name>Vaadin Application</display-name>
    <!-- ApplicationServlet from Vaadin jar will respond to requests. -->
    <servlet>
        <servlet-name>VaadinApplicationServlet</servlet-name>
        <servlet-class>com.vaadin.terminal.gwt.server.ApplicationServlet</servlet-class>
        <init-param>
        <!-- Define our application class for servlet. -->
            <param-name>application</param-name>
            <param-value>com.example.YourApplication</param-value>
        </init-param>
    </servlet>
    <!-- Make the servlet respond to all requests. -->
    <servlet-mapping>
        <servlet-name>VaadinApplicationServlet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
    <!-- session config -->
    <session-config>
      <session-timeout>30</session-timeout> 
    </session-config>
</web-app>

HTH.
