The easiest way would be something like that:

--------------- global functions.js ---------------
function getBaseUrl() {
  var url = new LzUrl();
  url = LzBrowser.getLoadURLAsLzURL();

  //return whatever you like... i.e. omit path
  return url.protocol + "://"
    + url.host + ":" + url.port + url.path;
}


--------------- Laszlo App ---------------
<datasource name="ds">
  <method event="oninit">
    this.currentroleds.setSrc(getBaseUrl() + 'FetchRoleServlet');
    this.mapserverData.doRequest();
  </method>
  <dataset type="http" name="currentroleds"/>
</datasource>
<script src="global_functions.js"/>
