Elastic Stack Elasticsearch

Hi,

I am trying to use the java client but a receive the following error:

javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/elasticsearch/client/RestClient

Could you please help me to solve this issue?

Best regards,

You need to add the client to your project. Which you probably did not.

I'd read: https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.3/index.html

I use java 1.6 and I have insert in my pom the following dependency:

	<dependency>
		<groupId>org.elasticsearch.client</groupId>
		<artifactId>elasticsearch-rest-client</artifactId>
		<version>6.2.4</version>
	</dependency>

The application builts successfully but when I try to use the RestClient, i receive the following error:
java.lang.NoClassDefFoundError: org/elasticsearch/client/RestClient

Not sure this is your issue but you need at least Java 1.8.
