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.
