HttpServletRequest interface extends the ServletRequest interface to provide request information for HTTP servlets. In this example, we are using Java 7 try-with-resources to automatically handle the closing of the ClosableHttpClient and we are also using Java 8 lambdas for the ResponseHandler. Solrj is a java client to access solr. HttpClient provides full support for HTTP over Secure Sockets Layer (SSL) or IETF Transport Layer Security (TLS) protocols by leveraging the Java Secure Socket Extension (JSSE).JSSE has been integrated into the Java 2 platform as of version 1.4 and works with HttpClient out of the box. A great walk-through for setting up a fully working example for both a Java client and server (using Tomcat) can be found on this website.
