question

We have a helper class called SpeechletServlet which is based on the HttpServlet specification, It handles requests coming from the Echo Platform.
Since this is based on the HttpServlet specifications. It can be hosted in any servlet container e.g. Tomcat which supported by AWS Elastic beanstalk.

Example Code:

package helloworld;
import com.amazon.speech.speechlet.servlet.SpeechletServlet;
@SuppressWarnings("serial")
public class HelloWorldServlet extends SpeechletServlet {
                
    public HelloWorldServlet() {
                
        this.setSpeechlet(new HelloWorldSpeechlet());
    }
}

Then add the new Servlet in your web.xml file:

<|?xml version="1.0" encoding="UTF-8"?>
<|web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://java.sun.com/xml/ns/javaee" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
id="WebApp_ID" version="2.5">
  <|servlet>
    <|servlet-name>HelloWorldServlet<|/servlet-name>
    <|servlet-class>helloworld.HelloWorldServlet<|/servlet-class>
  <|/servlet>
  <|servlet-mapping>
    <|servlet-name>HelloWorldServlet<|/servlet-name>
    <|url-pattern>/hello<|/url-pattern>
  <|/servlet-mapping>
<|/web-app>

e sure to copy all the Echo SDK /lib and /third-party dependencies to the WebContent/WEB-INF/lib folder of your AWS Elastic beanstalk project.
Then deploy you project to AWS Elastic Beanstalk and enable ssl - Configuring HTTPS for your AWS Elastic Beanstalk Environment
Thank you very much for your feedback.

Thanks!, One thing I'm struggling with is to find a [free] way to deploy my code without having to buy an SSL certificate! So I was hoping we could use self-signed certs. Or if Amazon could have an Echo AWS PaaS service where I can just deploy my code. Noel

We currently support self-signed Certificates for dev/test to support this very use-case. please see the Echo SDK Getting Started for details.
