Send HTML email in Java using URL as the content body

With the help of the Apache commons HttpClient we make a request to the given URL and then read the response data to insert that into the body of the email. The HTML email is done using the HtmlEmail class also available in the Apache commons library. This Java example uses gmail as its SMTP server but you can change that to anything of your choice, also the following jars are needed in the project classpath

• commons-email-1.2.jar
• commons-logging-1.1.1.jar
• httpclient-4.1.1.jar
• httpcore-4.1.jar
• mail.jar

   if (resEntity != null) {
    responseBody = EntityUtils.toString(resEntity);
   }
