Hi David,i will make it simple.My main moto is using java i want to do CRUD
operations with ElasticSearch,in this process i came to know about
ElasticSearch related Java
Api's URL :
http://www.elasticsearch.org/guide/en/elasticsearch/client/java-api/current/index.html
,from this i followed the steps as it is starting from Maven to Client
Api.I am using Eclipse Kepler and created WebDynamic Project and build the
respective jars,and copied the code from Client Api(Node based and
TransportClient) and execute using JavaApplication i.e.main() which uses
console app i.e. eclipse cmd. so,for now am trying atleast to connect to
Elasticsearch ,after getting this then i will move on with CRUD operations
using JSON. ANY GUIDANCE GIVEN WILL BE HIGHLY APPRECIATED.
URGENT REQUIREMENT.
Thanks in advance.
