        // printer.m_traceSelection = true;
        // printer.m_traceTemplates = true;
        // trMgr.addTraceListener(printer);
        XalanTraceListener traceListener = new XalanTraceListener(this);
        trMgr.addTraceListener(traceListener);
    } catch (TooManyListenersException e) {
    // ignore
    }
}

Example 2 with TraceManager

use of org.apache.xalan.trace.TraceManager in project mycore by MyCoRe-Org.

 * Returns a new transformer for the compiled XSL templates
 */
public static Transformer getTransformer(Templates templates) throws TransformerConfigurationException {
    Transformer tf = factory.newTransformerHandler(templates).getTransformer();
    // In debug mode, add a TraceListener to log stylesheet execution
