Examples with DiscoveryListener org.apache.openejb.server.DiscoveryListener used on opensource projects

Example 1 with DiscoveryListener

use of org.apache.openejb.server.DiscoveryListener in project tomee by apache.

the class Tracker method fireServiceAddedEvent.

private void fireServiceAddedEvent(final URI uri) {
    if (log.isInfoEnabled()) {
        log.info(String.format("Added Service{uri=%s}", uri));
    }
    if (discoveryListener != null) {
        final DiscoveryListener discoveryListener = this.discoveryListener;
        // Have the listener process the event async so that
        // he does not block this thread since we are doing time sensitive
        // processing of events.
        executor.execute(new Runnable() {

            @Override
            public void run() {
