RESTful Java Client With Apache HttpClient using POST

If you are using maven you can get httpclient from:

<dependency>
<groupId>org.apache.httpcomponents</groupId>
 <artifactId>httpclient</artifactId>
 <version>4.1.1</version>
 </dependency>

So this is my implementation of an RESTful java web service using POST.
I decided I should make this because I see a lot of tutorials on how to make a GET restfull service but I didn't find one with POST, or what I have found did not really work for me.
