Currently I'm learning to build a REST API (backend) with the ionic application (frontend), but I'm facing an issue in backend REST API deployment. Thus, I'm asking this question to get some clues and answers related to REST API deployment, since I'm really new and no clue how to deploy a REST API. I had checkout some tutorial on youtube, but it seem like most of the example in videos are not using the technologies or environment that same as the REST API I built. The following shown the technologies I used to built my system frontend and backend:
REST API (BACKEND):
Language: Java, Spring MVC Framework
Database: Hibernate, Oracle SQL Developer
Web App Build Technology: Gradle, Gretty (To app start my application)
Ionic Application (FRONTEND):
Technologies: Angular Framework, HTML, CSS
How the application is working in localhost?
STEP 1: I will app start using Gretty plugin in gradle
STEP 2: I active the command "ng serve" (ionic serve) to run my ionic application
STEP 3: After both frontend and backend is successfully run, now I can access the provided link that generated from ng serve to access my web app and do anything I want.
Everything is working perfectly in local system, but it is different case when I test my ionic web app through my smartphone (Since ionic allows us to build progressive web app). The frontend ionic application will not able to communicate with backend when the operating environment of frontend is not in local system and I know it's really make sense, since my backend REST API haven't deploy which only able to operating on localhost. Therefore, I'm have tried to find solution on youtube and other internet sources to deploy my rest api online, but I don't see any information or deployment video that using the same technologies as I used to built my rest api (Spring MVC, oracle developer, gradle).
Thus, I'm asking this "stupid" question in here to find out whether any solution to deploy my rest api? or any suggestion to change the technologies that I used to built my rest api? or any mistakes I had made which violate the best coding practice in building rest api.
As a new programmer, I really appreciate the answers from all you guys. Thank you.
First, let's explain some concepts:
You backend is the application you coded, deployed on a server that exposes an endpoint for access - e.g. http://localhost:8080/yourApp - where your host/domain is your current computer (localhost) and the port is 8080 or anything you setup.
If you want to access from you smartphone:
1) Since your app is hosted on your pc, you need to be connected to the same wifi network
2) From your host machine, where you deployed your app, look for your ip address.
open your console/terminal
type ipconfig/ifconfig
look for your wifi and copy ipv4 address
3) redeploy your frontend pointing to your host machine ip
It worked before because you where on the same machine (localhost means redirect to your own device). When you switched to your phone it, also, redirects to your own smartphone.

I'm going to start developing a new simple "X management" kind app, like contact management or events management. What I want to know is which tools would be the best to achieve it in the way I want.
My app needs to be a web app running on a server that has a mysql database to save and retrieve some simple information. This app must have a web client but I want it to be able to be extended to work with an Android app client.
Things I've thought:
I've worked on Java with facelets and JPA travels management app running on a GlassFish server on localhost with a JSF web view, so maybe my web client and the full app could be done with this.
I've worked with web services such as SOAP and REST with Jaxb and xml schemes to retrieve information parsing some webs into xml or json to show on a client .net app. So I've thought I can add to my app, like last topic we talked about, a REST web service layer to easily work as I want, or at least I think it would be easy. If I do this the Android app could share the same app core code but using the REST service.
My question is what could be the best way to do an app with 2 client side in different platforms that could share some code to be easy to extend it moreover to a desktop app. I've talked about these 2 options because I'm a students of computers at university and those are the tools I know, but I can easy learn more. I've also think about just a REST service and create a web and an Android client to work on same service or something like that.
This post is getting long, so here is the summary: What technologies and tools do you think are the best choice to create an java web app that needs to have web and Android client? Also what server, like tomcat, GlassFish or another, should I use? And what about persistence layer? JPA with mysql is the best I know to work with.
Thanks a lot.
P.D: I work with eclipse
From my point of view:
You can use java jersey and java spring both ( java spring as Dependency injection) for creating RESTful Web service. So, In server side you will create endpoint and you can access data from any platform through those endpoint.
Server can be anyone. It's up to you. I always try to use tomcat but tomcat is not a full JavaEE container it's only a servlet container. So if you want to use full JavaEE version then you should use Glassfish.
And yes JPA .It can be easily used in any environment supporting JPA including Java SE applications, Java EE application servers, Enterprise OSGi containers etc.
On the other hand, still choice is yours.
I have just learned to create java rest API using jersey and Oracle database.
I'm developing in eclipse and using weblogic server to run and test web service on localhost.
My question is what are the options of live servers to deploy this service so that I can access this API in my android application or any web application???
You can do that. But you have to make sure that all the dependent jars are packaged with the your WAR project(eg; Oracle db related things).
Some blog entries which give you an idea about what are all these servers and which one to pick for open development and common standards - http://blogs.forrester.com/mike_gualtieri/11-07-15-stop_wasting_money_on_weblogic_websphere_and_jboss_application_servers,
and this one http://zeroturnaround.com/rebellabs/the-great-java-application-server-debate-with-tomcat-jboss-glassfish-jetty-and-liberty-profile/
This will give pretty good idea about what is all these servers :)
we are working on our graduation project project that has two main block
1- A website that is written in ASP.NET
2- A webservice that access the database (mySQL DB) , do some processing on data and communicate with that website to show the results.
We are using a java library [Apache Mahout] in that webservice to help us do that processing and that's why we need to write this webservice in JAVA
How can we create and host a Restful java webservice on Windows Azure ? What are the available options ?
Also , Is it possible to start the processing and stop it depending on a request that is sent from the website or another block (another webservice for example) ?
I hope the situation is now clear.I would appreciate if you could provide us with any resources that could help us understand how Restful java Webservice in Azure works :)
Today you have two options for running Java on Windows Azure: Cloud Services and Virtual Machines. Cloud Services (Platform as a Service) enable you to package up a web deployment (WAR) along with a JDK and your java server of choice (Jetty, tomcat, Jboss, etc) and deploy it. Your other option is to use a virtual machine (Infrastructure as a Service). You have a few different options for virtual machines (including officially supported Oracle images: http://www.windowsazure.com/en-us/campaigns/oracle/).
Your easiest option will be looking at Cloud Services (though this does require packaging no a Windows computer). There is a great Windows Azure plugin for Eclipse that will help you out tremendously (http://msdn.microsoft.com/en-us/library/windowsazure/hh694271.aspx). There are also a lot of tutorials, resources, and links to references here: http://www.windowsazure.com/en-us/develop/java/.
Azure websites now supports Java web applications - check it out - http://azure.microsoft.com/en-us/documentation/articles/web-sites-java-get-started/ - you use the default JDK 7 with Tomcat 7.0.50 or Jetty 9.1.0 OR you can even upload your own web container and configure it as per your requirements. Please refer to the link above.
I have created a Java web service using Axis2 Framework/Eclipse and deployed it on Azure Websites.
I want to utilise the Facebook JavaScript API in the client, but manage app logic and configuration on the server through REST web services. I've tried a lot of tutorials out there, but so far I haven't seen one that actually works.
What do you recommend as a server / web framework?
What technology should I use for my REST endpoints?
How can I host this application in a place where facebook will "see" it as a valid app?
I'm looking for a comprehensive tutorial or set of recommended practices to get started.
Thanks
I just so happened to create a blog series that takes you through EVERYTHING you will need. The articles:
Setup Eclipse (IDE) and JBoss AS7 (server)
Setup other JBoss Tools including Forge
Setup JAX-RS Web Service in Java using Forge (very easy!)
Setup account to Host the site for FREE with OpenShift
Setup an entire sample Facebook App
This blog series should be EXACTLY what you're looking for. You can find the first of three articles here:
http://ocpsoft.org/opensource/creating-a-facebook-app-setup-and-tool-installation/
I would recommend going with Spring Social module with has a good abstraction of the Facebook API.
You could then expose these services via REST with Spring Web Services or Jersey.
I am not sure about the hosting. Facebook should see it as a valid application no matter the host. Even your development computer/localhost cando it.
I'am developing a java servlet application, and tesing it on Eclipse + Apache Tomcat (refer: http://www.vogella.de/articles/EclipseWTP/article.html#overview_wtp).
The application is now tested on the localhost and accesed by any clients on the same LAN.
Now, I need to deploy it into the web server, where everyone from anywhere can access this servlet.
Coud you guide me the way that I've to do to archive this task.
You need to have a computer accessible to everyone - i.e. placed on the internet and not behind a firewall - with the appropriate software installed (and hardened against hacker attacks).
If you do not have such a computer, you can have a look at the Google Application Engine which allows you to deploy Java web applications (with some additional restrictions) to the Google cloud. This is free for low-volume applications.
Yes, you can do it by deploying your application in the Cloud Instance. Since we cannot able to make our server instance or computer to be run always(We may come across internet connection problems, Power Fluctuation, etc.,), We have lot of problems while making our instance public(In Security perspective too). So it is better to use cloud instances.
We have many Cloud Service Providers such as AWS by Amazon, Google Cloud, Microsoft Cloud, etc.,
Take a look on this List of Cloud Services Providers.(You have links for all top 10 providers)
