| /** |
| * An extension of <code>SQLException</code> that provides information |

| * Warnings are silently chained to the object whose method call |
| * caused it to be reported. |
| * This class complements the <code>SQLWarning</code> class. |
| * <P> |
| * Rowset warnings may be retrieved from <code>JdbcRowSet</code>, |
| * <code>CachedRowSet</code>™, |
| * <code>WebRowSet</code>, <code>FilteredRowSet</code>, or <code>JoinRowSet</code> |
| * implementations. To retrieve the first warning reported on any |
| * <code>RowSet</code> |
| * implementation, use the method <code>getRowSetWarnings</code> defined |
| * in the <code>JdbcRowSet</code> interface or the <code>CachedRowSet</code> |
| * interface. To retrieve a warning chained to the first warning, use the |
| * <code>RowSetWarning</code> method |
| * <code>getNextWarning</code>. To retrieve subsequent warnings, call |
| * <code>getNextWarning</code> on each <code>RowSetWarning</code> object that is |
| * returned. |
| * <P> |
| * The inherited methods <code>getMessage</code>, <code>getSQLState</code>, |
| * and <code>getErrorCode</code> retrieve information contained in a |
| * <code>RowSetWarning</code> object. |
