Hi! I'm totally new to elasticsearch and I have troubles with elasticSearch + Java. System: Windows 7 (VirtualBox) Eclipse JavaEE (Kepler) JDK7 elasticsearch-0.90.3 Here is what I tried: Started two nodes (cmd): .../elasticsearch.bat checked by browser ([http://127.0.0.1:9200](http://127.0.0.1:9200)) --\> everything seems fine. checked by cmd (curl -XGET [http://127.0.0.1:9200/\_cluster/health?pretty](http://127.0.0.1:9200/_cluster/health?pretty)) --\> ok! Then I created a new Java Project: (added "elasticsearch-0.90.3.jar" and "lucene-core-4.4.0.jar" in the build path) import org.elasticsearch.node.Node; import static org.elasticsearch.node.NodeBuilder.\*; public class test { public static void main(String[] args) { Node node = nodeBuilder().clusterName("elasticsearch").node(); node.close(); } } And the result is: Aug 08, 2013 1:44:46 PM org.elasticsearch.node INFO: [Crown] version[0.90.3], pid[2724], build[5c38d60/2013-08-06T13:18:31Z] Aug 08, 2013 1:44:46 PM org.elasticsearch.node INFO: [Crown] initializing ...

The result is not showing up, and without it, we cannot help. 🙂 The elasticsearch jar should contain all the relevant Lucene class, so there is no need to use the Lucene jar. -- Ivan On Thu, Aug 8, 2013 at 5:22 AM, Atelophobia [new-account@gmx.net](mailto:new-account@gmx.net) wrote: > Hi! > > I'm totally new to elasticsearch and I have troubles with elasticSearch + > Java. > > System: > Windows 7 (VirtualBox) > Eclipse JavaEE (Kepler) > JDK7 > elasticsearch-0.90.3 > > Here is what I tried: > > Started two nodes (cmd): .../elasticsearch.bat > checked by browser ([http://127.0.0.1:9200](http://127.0.0.1:9200)) --\> everything seems fine. > checked by cmd (curl -XGET [http://127.0.0.1:9200/\_cluster/health?pretty](http://127.0.0.1:9200/_cluster/health?pretty)) > --\> ok! > > Then I created a new Java Project: > (added "elasticsearch-0.90.3.jar" and "lucene-core-4.4.0.jar" in the build > path) > > And the result is: > > -- > View this message in context: > [http://elasticsearch-users.115913.n3.nabble.com/Beginner-Question-ElasticSearch-and-Java-API-tp4039323.html](http://elasticsearch-users.115913.n3.nabble.com/Beginner-Question-ElasticSearch-and-Java-API-tp4039323.html) > Sent from the Elasticsearch Users mailing list archive at [Nabble.com](http://Nabble.com). > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > For more options, visit [https://groups.google.com/groups/opt\_out](https://groups.google.com/groups/opt_out). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
