title: How to add more hbm to existing mappingResources or existing hbm list in Spring
body: <p>I have a parent-app, which includes sub-apps.
  My Parent app has its own included list of hbms </p>
  
  <pre><code>   &lt;bean name="mappingResources"
        class="my.xxx.MyListFactoryBean"&gt;
          &lt;property name="sourceList"&gt;
              &lt;list&gt;
                  &lt;value&gt;aaa/bbb/aa.hbm.xml&lt;/value&gt;
                  &lt;value&gt;aaa/bbb/bb.hbm.xml&lt;/value&gt;
                  &lt;value&gt;aaa/bbb/cc.hbm.xml&lt;/value&gt;
              &lt;/list&gt;
        &lt;/property&gt;
      &lt;/bean&gt;
  </code></pre>
  
  <p>My sub-apps want to add its own list of dependent hbms to the parent-app's.
  The way it should work is, if it includes this sub-app then it would include the new hbms as well and the child-app would initiate the include.</p>
  
  <p>new hbms to be included could look like</p>
  
  <p>xx/dd.hbm.xml
  xx/ee.hbm.xml</p>
  
  <p>How can we do it?</p>
