Hello ,

I have to instantiate ES within a Tomcat process. Normally ES is instantiated as a separate process and clients connect to it.  
What I would like to do is to instantiate the ES within a Tomcat and connect to it using a client. How do I tell the Tomcat to instantiate Elasticsearch class so that the ES gets started when the Tomcat instance is up.

Embedding Elasticsearch is no longer supported, as outlined [in this blog post](https://www.elastic.co/blog/elasticsearch-the-server).

Thanks Christian for directing me to this post.  
Just out of curiosity what if I call the main method of Elasticsearch class using reflection and start it?  
I know this is not a good idea but will there be any repercussion in such a case?
