title: updating welogic.xml
body: <p>my weblogic.xml looks like this</p>
  
  <pre><code>&lt;security-role-assignment&gt;
  &lt;role-name&gt;employee&lt;/role-name&gt;
  &lt;principal-name&gt;scott&lt;/principal-name&gt;
  &lt;principal-name&gt;john&lt;/principal-name&gt;
  &lt;principal-name&gt;peter&lt;/principal-name&gt;
  &lt;/security-role-assignment&gt;
  </code></pre>
  
  <p>But when i add new employee(programmatically) lets us say 'mark' i want weblogic.xml
  to be updated for 'mark' also. Actually i can see new employee in admin portal.
  But weblogic.xml will not be updated.
  How to this programmatically. Any suggestions.</p>
  
  <p>Thanks </p>
