Where can I deploy my java REST webservice for free so that I can access it remotely?

I have developed a REST web-service in Java interacting with a MySQL database.I want to deploy the web-service and the create a database at a server so that I can invoke it from an application.I tried Microsoft Azure but was unable to get it done.Where can I find relevant information for this?

I had similar problems with a MySQL database using the third party option in the Azure Marketplace from ClearDb. What I ended up doing was switching my database from a MySQL instance to an Azure Database Instance (Subset of SQL Server's features.) This worked perfectly for me! I was able to query from my database feed data to my api, and access the API through my Azure Web App.
I understand this may not be an option for you, however, Digital Ocean is a great cloud hosting option (with scaling similar to Azure, although not as good in my honest opinion.) You can set up a Linux Environment with a MySQL Server and JVM and serve your whole API through there. Best of Luck!

#coderden, According to your description, I think you have been deployed your Java Application on an Azure WebApp. Then when you created a MySQL database on Azure for connection from the Java webapp, please make sure the webapp & mysql instance created in a same resource group and note the connection string of MySQL on Azure.
As reference, please see the article to try again although it's for PHP, the steps are the same for Java.

Creating Java Restful webservice on Windows Azure

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.

linking my java web application to the web?

I am beginner java web developer, now my question is after i developed my application, how to make users see it on the web?
I used JSF,MySQL and GlassFish server in my development stage and now i want to publish it.
I got a domain name and an a web hosting account on goDaddy.com
In other words what to do after i develope my web application?
what steps should i take in server creation and other stuff?
I have searched alot but there is no specific way for it. I am trying to make this dynamic website based on jsf development--and it is already done--become alive and out their like any other web site?
any guide lines and steps should i take in making this steps ?

Either you will need a "Production" server to host the application yourself or use a hosting service of some kind that provides a Java EE container. If you're tied to Glassfish, you can Google for those providers like http://glassfishhosting.com/.
Other options that might be good fits for you are cloud services. Something like either Rackspace or Amazon EC2. Each has their own pricing tiers that scale based on usage. Good luck to you going Live!

Can host the code on Github and push it to Heroku.

I don't know the provider you chose but you need a java application server for your live environment. And optimally this should be the same server as your development server.
For our projects we buy a virtual server and install Glassfish on it. This costs around 15 € per month and we have the same environment for development and production.

running php and java on the same server

I have web services written using java which interacts with the android application only now we need to implement a front end web portal using php frame work codeigniter. We have common database mysql 5.1 which interacts with both the web services and also web portal, is it possible to configure the LAMP stack in a server which is already running tomcat6 servlet container but with out apache web server. How do I processed further and when Iwas search for same issuse I found something called php java bridge is that what I have to use??
Let me be more precise on this, I have ec2 ubuntu instance already running, domain is parked in godaddy, i have configured the A records with the ip of my ec2 instance, so when the requests comes in it will be directed to the application which is running in the tomcat6/webapps/ROOT but now I need to redirect it to the php application how do I do it and also requests from android should be directed to web services which are java based, how do I manage this?
Kindly help out

You can proxy requests to the tomcat server from Apache ... have two virtual hosts, one for the tomcat and one for the php ... all co-ordinated by apache.
http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html
It is recommended that you also read the Workers HowTo document to learn how to setup the working entities between your web server and Tomcat Engines. For more detailed configuration information consult the Reference Guide for workers.properties, uriworkermap and Apache.

Server to run java servlet

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)
