I am working on x-pack watcher. I have added dependency of x-pack. > org.elasticsearch.client x-pack-transport 5.3.3 org.apache.logging.log4j log4j-api 2.7 org.apache.logging.log4j log4j-core 2.7 I can create watcher using curl request but unable to create from java code. I have created a watcher using curl and try to get it from jave code. here is my code. > package watcher; > > import java.net.InetAddress; > import java.net.UnknownHostException; > import java.util.Map; > > import org.elasticsearch.client.transport.TransportClient; > import org.elasticsearch.common.settings.Settings; > import org.elasticsearch.common.transport.InetSocketTransportAddress; > import org.elasticsearch.xpack.XPackClient; > import org.elasticsearch.xpack.client.PreBuiltXPackTransportClient; > import org.elasticsearch.xpack.watcher.client.WatcherClient; > import org.elasticsearch.xpack.watcher.support.xcontent.XContentSource; > import org.elasticsearch.xpack.watcher.transport.actions.get.GetWatchResponse; > > public class GetWatcher { > > ``` > public static void main(String[] args) throws UnknownHostException { > > @SuppressWarnings("resource") > TransportClient client = new PreBuiltXPackTransportClient( > Settings.builder().put("cluster.name", "my-application").build()) > .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300)); > > XPackClient xpackClient = new XPackClient(client); > WatcherClient watcherClient = xpackClient.watcher(); > > GetWatchResponse getWatchResponse = watcherClient.prepareGetWatch("my-watch").get(); > XContentSource source = getWatchResponse.getSource(); > Map map = source.getAsMap(); > for (String key : map.keySet()) { > System.out.println(key); > } > > } > > ``` > > } Error- > ERROR StatusLogger No log4j2 configuration file found.

Your error specifies a `java.lang.ClassNotFoundException` Try adding the following to your build.gradle (or pom or whatever build tool you are using). ```auto compile 'com.unboundid:unboundid-ldapsdk:3.2.0' compile 'org.bouncycastle:bcprov-jdk15on:1.58' compile 'org.bouncycastle:bcpkix-jdk15on:1.58' ``` Thanks, Baz. ---
