	 * <ul>
	 * If file type is MESSAGEFILE ,
	 * <li>Search file with the file locator (<code>IResourceLocator</code>)
	 * in session. And Now just deal with relative file name.
	 * 
	 * <ul>
	 * If file type isnot MESSAGEFILE,
	 * <li>Search file taking <code>fileName</code> as absolute file name;
	 * <li>Search file taking <code>fileName</code> as relative file name and
	 * basing "base" property of report design;
	 * <li>Search file with the file locator (<code>IResourceLocator</code>)
	 * in session
	 * </ul>
	 * 
	 * @param fileName
	 *            file name to search
	 * @param fileType
	 *            file type. The value should be one of:
	 *            <ul>
	 *            <li><code>IResourceLocator.IMAGE</code>
	 *            <li><code>IResourceLocator.LIBRARY</code>
	 *            <li><code>IResourceLocator.MESSAGEFILE</code>
	 *            </ul>
	 *            Any invalid value will be treated as
	 *            <code>IResourceLocator.IMAGE</code>.
	 * @return the <code>URL</code> object if the file with
	 *         <code>fileName</code> is found, or null otherwise.
