Error in deploying EAR in glassfish

I'm trying to deploy ear in glassfish from eclipse. My project structure of EAR is the following

EAR
-SampleWebApplication
-SampleEJBApplication
BrokerTool (Java Application)

My application.xml file is

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns:xsi="http://ift.tt/ra1lAU" xmlns="http://ift.tt/nSRXKP" xmlns:application="http://ift.tt/W0LURl" xsi:schemaLocation="http://ift.tt/nSRXKP http://ift.tt/1evQWgx" id="Application_ID" version="6">
  <display-name>EAR</display-name>
  <module>
    <web>
      <web-uri>SampleWebApplication.war</web-uri>
      <context-root>SampleWebApplication</context-root>
    </web>
  </module>
  <module>
    <ejb>SampleEJBApplication.jar</ejb>
  </module>
</application> 

I click on EAR project Run As->Run on Server, I choose my glassfish and get the error.

 Severe: Exception during lifecycle processing
    java.lang.IllegalArgumentException: Could not find sub module [SampleWebApplication.war] as defined in application.xml
