Why can't I connect to ElasticSearch through Java API? -

i'm having trouble connecting vanilla elasticsearch cluster via java api.

to reproduce:

#start elasticsearch elasticsearch -f  #checking in new window $ curl -xput 'http://localhost:9200/twitter/tweet/1' -d '{\     "user" : "kimchy",\     "post_date" : "2009-11-15t14:12:12",\     "message" : "trying out elastic search"\ }' 

result:

{   "ok": true,   "_index": "twitter",   "_type": "tweet",   "_id": "1",   "_version": 3 } 

---

$ curl -xget 'http://localhost:9200/twitter/tweet/_search?q=user:kimchy' 

result:

{   "took": 2,   "timed_out": false,   "_shards": {     "total": 5,     "successful": 5,     "failed": 0   },   "hits": {     "total": 1,     "max_score": 0.30685282,     "hits": [       {         "_index": "twitter",         "_type": "tweet",         "_id": "1",         "_score": 0.30685282,         "_source": {           "user": "kimchy",           "post_date": "2009-11-15t14:12:12",           "message": "trying out elastic search"         }       }     ]   } } 

so, works via http. trying via java (per this page):

public static void main(string[] args) {      client client = new transportclient()     .addtransportaddress(new inetsockettransportaddress("localhost", 9200));      indexresponse response = null;     try {       response = client.prepareindex("twitter", "tweet", "1")           .setsource(xcontentfactory.jsonbuilder()                       .startobject()                           .field("user", "john")                           .field("postdate", new date())                           .field("message", "who dont work")                       .endobject()                     )           .execute()           .actionget();     } catch (elasticsearchexception e) {       // todo auto-generated catch block       e.printstacktrace();     } catch (ioexception e) {       // todo auto-generated catch block       e.printstacktrace();     }      system.out.println(response); } 

and following stack trace:

may 21, 2013 8:27:42 org.elasticsearch.plugins info: [bes] loaded [], sites [] may 21, 2013 8:27:49 org.elasticsearch.client.transport info: [bes] failed node info [#transport#-1][inet[localhost/127.0.0.1:9200]], disconnecting... org.elasticsearch.transport.receivetimeouttransportexception: [][inet[localhost/127.0.0.1:9200]][cluster/nodes/info] request_id [0] timed out after [5002ms]     @ org.elasticsearch.transport.transportservice$timeouthandler.run(transportservice.java:342)     @ java.util.concurrent.threadpoolexecutor$worker.runtask(threadpoolexecutor.java:895)     @ java.util.concurrent.threadpoolexecutor$worker.run(threadpoolexecutor.java:918)     @ java.lang.thread.run(thread.java:680) exception in thread "main" org.elasticsearch.client.transport.nonodeavailableexception: no node available     @ org.elasticsearch.client.transport.transportclientnodesservice.execute(transportclientnodesservice.java:202)     @ org.elasticsearch.client.transport.support.internaltransportclient.execute(internaltransportclient.java:106)     @ org.elasticsearch.client.support.abstractclient.index(abstractclient.java:84)     @ org.elasticsearch.client.transport.transportclient.index(transportclient.java:310)     @ org.elasticsearch.action.index.indexrequestbuilder.doexecute(indexrequestbuilder.java:315)     @ org.elasticsearch.action.actionrequestbuilder.execute(actionrequestbuilder.java:62)     @ org.elasticsearch.action.actionrequestbuilder.execute(actionrequestbuilder.java:57)     @ scratch.main(scratch.java:30) 

and closest thing i've found far problem here, thread trailed off without resolution.

the transportclient default port 9300. have use instead of 9200 in java code. why connection fails.
