Example 10 with ContextHandler

use of org.eclipse.jetty.server.handler.ContextHandler in project jetty.project by eclipse.

the class DebugListener method contextInitialized.

@Override
public void contextInitialized(ServletContextEvent sce) {
    sce.getServletContext().addListener(_servletRequestListener);
    ContextHandler handler = ContextHandler.getContextHandler(sce.getServletContext());
    handler.addEventListener(_contextScopeListener);
    String cname = findContextName(sce.getServletContext());
    log("^  ctx=%s %s", cname, sce.getServletContext());
    if (_dumpContext) {
        if (_out == null)
            handler.dumpStdErr();
        else {
            try {
                handler.dump(_out);
            } catch (Exception e) {
                LOG.warn(e);
            }
        }
    }
