   Server version (2.3.0) is not newer than 2.4.0

Here is my web.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

  <servlet-mapping>

    <url-pattern>/stockwatcher/greet</url-pattern>
  </servlet-mapping>

  <!-- Default page to serve -->
    <welcome-file-list>
    <welcome-file>StockWatcher.html</welcome-file>
  </welcome-file-list>

</web-app>

Here is StockWatcher.gwt.xml:

<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='stockwatcher'>
  <inherits name='com.google.gwt.user.User'/>

  <inherits name='com.google.gwt.user.theme.clean.Clean'/>

  <entry-point class='com.company.gwt.stockwatcher.client.StockWatcher'/>

  <source path='client'/>
  <source path='shared'/>

</module>

The problem repeats even if I download the project from tutorials page. How can I resolve the problem?

UPD: Strange, but when I tried to launch it again (no changes) I got "Problem occured" window:

‘Launching StockWatcher’ has encountered a problem.

Variable references empty selection: ${container_path}

Any idea why this happens?

    Resolved the problem by deleting debug configuration. When I tried to run in debug mode Eclipse has generated new debug configuration and everything worked fine.
