title: Spring EL not loading SystemProperties
body: <p>I am using below configuration in context xml file to load properties in Java code, but i am getting just property name instead of value. when i run my app server and tries to access sytem properties using below way, it doesn't work. but if i use System.getProperty('') then it works. I dont know what i am missing.</p>
  
  <pre><code>&lt;bean id="bean1" parent="parentBean"&gt;
       &lt;property name="beanDao" ref="beanDao"/&gt;  
      &lt;property name="outputLocation"  value= "#{systemProperties['PRO1.LOCN']}"/&gt;
  
  &lt;/bean&gt;
  </code></pre>
  
  <p>Java file:</p>
  
  <pre><code>@Override
  public String getOutputLocation() throws Exception {
      // TODO Auto-generated method stub
      return outputLocation;
  }
   * @param outputLocation
   *            the outputLocation to set
   */
  public void setOutputLocation(String outputLocation) {
      this.outputLocation = outputLocation;
  }
  </code></pre>
