How to deploy JAVA Application on Azure Service Fabric

At this moment, Azure Service Fabric does not support JAVA application natively (but it's on the support roadmap). However, we can host the JAVA application as a Guest Executable for the time being.

In this article, I will walk you through how to deploy JAVA application on Azure Service Fabric in details.

1. Prepare JAVA Application
   I follow the Embedded Jetty Examples to create a simple file server.
   The source code is like below.
   

    1 package org.eclipse.jetty.embedded;
    2 
    3 import org.eclipse.jetty.server.Handler;
    4 import org.eclipse.jetty.server.Server;
    5 import org.eclipse.jetty.server.handler.DefaultHandler;
    6 import org.eclipse.jetty.server.handler.HandlerList;
    7 import org.eclipse.jetty.server.handler.ResourceHandler;
    8 
    9 public class FileServer {
   10 
   11     public static void main(String[] args) throws Exception{
   12         // TODO Auto-generated method stub
   13         // Create a basic Jetty server object that will listen on port 8080.  Note that if you set this to port 0
   14         // then a randomly available port will be assigned that you can either look in the logs for the port,
   15         // or programmatically obtain it for use in test cases.
   16         Server server = new Server(8080);
   17         
   18         // Create the ResourceHandler. It is the object that will actually handle the request for a given file. It is
   19         // a Jetty Handler object so it is suitable for chaining with other handlers as you will see in other examples.
   20         ResourceHandler resource_handler = new ResourceHandler();
   21         
   22         // Configure the ResourceHandler. Setting the resource base indicates where the files should be served out of.
   23         // In this example it is the current directory but it can be configured to anything that the jvm has access to.
   24         resource_handler.setDirectoriesListed(true);
   25         resource_handler.setWelcomeFiles(new String[]{ "index.html" });
   26         resource_handler.setResourceBase(".");
   27         
   28         // Add the ResourceHandler to the server.
   29         HandlerList handlers = new HandlerList();
   30         handlers.setHandlers(new Handler[] { resource_handler, new DefaultHandler() });
   31         server.setHandler(handlers);
   32         
   33         // Start things up! By using the server.join() the server thread will join with the current thread.
   34         // See "http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Thread.html#join()" for more details.
   35         server.start();
   36         server.join();
   37     }
   38 
   39 }
