I want to Deploy my server side java application on a server. I choose to use Heroku.
Currently, I am able to create server and client side application on java and run them from my laptop on different terminals and communicate between them. Now I want to do same over the internet and choose Heroku server but I don't understand how to deploy my application on its server. I tried to read their tutorial but I am not able to understand from it. Tutorials on youtube and other are very old.
Help me deploy my application to Heroku . I use Eclipse and know how to use git. Let me know if you need any other info.
Edit: As my first server application I would like to deploy a chat box. I will execute client side from my laptop and launch the server side (created by me) from Heroku.

I want to create web server for (localhost) which:
1-provides HTML code (https://leafletjs.com/)
2-receives requests (Ajax requests) from the client that calls corresponding methods in the backend and their send the result back to the client.
Install an "Apache Tomcat" application server and write a "Servet Application" or use "Java Server Faces". Google for those keywords.
I wrote a german tutorial about this: http://stefanfrings.de/jsf_tutorial/index.html there is a translation link in the upper right corner.
If you do not want to install an application server, then you may prefer to use Jetty, which is basically the same as Tomcat but embedded in your own executable program.
So I just got internship at this company, and they would like me to complete a project(Web application) which someone else did but didn't finish two years ago. But the person didn't leave any documentation about this web app. Right now I would like to run and test this web app, but I couldn't get it started.
So it's running on WebSphere Application Server in IBM Rational Application Developer, the code is written in java and javascript. (I could start the server, but I don't know where to go and open up the web app)
Sorry I'm really new to this, questions might be stupid, appreciate any help:)
Do you know what port it's running on? You should be able to access it from a web browser on the host machine by going to
http://127.0.0.1:XX
where XX is the port in question. If you don't know, try 80 - that's the default HTTP port and it's worth a shot.
The default websphere web port is 9080, so try http://localhost:9080/
So it's running on WebSphere Application Server in IBM Rational Application Developer
and
I could start the server
Assuming you are able to start the server via RAD as I assume from the above and you are able to publish the app to WebSphere via RAD, you should then be able to right click on the project folder and choose "Run on Server." It will walk you through publishing the app to the server and will then launch a browser to the index page or URL via the context path and web project settings. You can have RAD use an embedded browser (default) or adjust it to launch an external browser via Preferences -> Web Browser.
To manually check where a webapp will be deployed you can either check application.xml (if you have one) OR you can right click on the project root folder in RAD, choose Properties, and Web Project Settings. The context path is in a field there.
Run-On-Server will show you both server/hostname (usually localhost), port, and application context path in one operation.
I have build one chat application, which consists of server and client part & backend uses sql server 2005. Now i want to deploy my chat app on Apache web server. by converting it to exe and allow users an option to download my exe file through jsp file.
Now what i need to know is:
What exactly i need to convert in exe(is it server or client or both seperately).
Can my chat application automatically access database if i convert it into exe.
Do i need to deploy both client and server exe on web server.
I hope i am clear enough.
I am learning Java and am trying to do some experiments with networking Java programs.
I have a program made in 2 parts with a client and a server and it works in local testing but the program actually has usefulness for me and a friend of mine and I want to put the server online so both of us can connect to it and use it.
Where/How can I put the program online and have it running so that the client programs can connect to the ServerSocket with an ip address? (Preferably free)
If you dont want to pay server hosting then I would open a virtual server on my computer, then playaround with modem and forward related port to server ip. I would use a port more than 40000. Then just send your ip and port your friend or update application.
If you really want the application to go live within 5 mins, try Jelastic. If you have built a WAR file, simply sign up with their server,choose a provider closest to your geo location, configure Tomcat and you can upload the WAR file through their fantastic web console. Otherwise if you have some source control system(SVN,GIT etc), you just connect and build it with their Maven console and you can be ready. I used it for my start up(Cloudlabz) and really found it exciting.

You could also consider the cheapest Rackspace Cloud Server. You'll get a full fledged Linux server (distribution of your choice) for about USD 11/month. I've done that now and then myself to try things out.
Just install Java on it and you're good to go.

http://ideone.com/
is that what you want for this?
This is a free web app for you to run your program online....so you can just paste your code and run it.
On the cloud you could use two different services in order to host your Java application.
IaaS (Infrastructure as a Service). Where you can just rent a specific infrastructure on the cloud and you could install and configure all the services that you need.
PaaS (Platform as a Service). In this case, you still enjoy the infrastructure on the cloud + the service Aaren full pre-configured. It means that you can deploy your application without installing or configuring anything. You just need to deploy your application. You have an example about how it works here. Also, you usually can test your Java apps on the cloud without paying.
You should host the server in Heroku ,they offer a free hosting with limits , I have an app there
I would like to know if I purchase a VPS service(linux based) over the net.
Do I need Tomcat to be installed in order to launch my java based server (socket server)?
If yes Which version do I need, and can you please give me a reference for an online guide for how to install and run things on a VPS which is based on Linux.
Thanks
If your are not deploying web apps (WAR's), you don't need a application server like tomcat or glassfish. So to run your java based server, you only need the JRE.
Get a Windows-based VPS if you are not familiar with Linux, as you have to administrate the server (apply patches, etc.), if it is not managed by your provider.
Have a look at this Superuser question for Linux books.
