Develop Java cloud applications in Eclipse
In this article we will talk about the Windows Azure Toolkit tools for Eclipse and the development of Java cloud applications using them.
Windows Azure Toolkit for Eclipse is an open source toolkit that adds functionality to the Eclipse development environment and allows Java application developers to conveniently develop, manage, and publish applications to the Windows Azure cloud .

You can find out more about the project at the following links:
To install the Windows Azure Toolkit for Eclipse add-on, you need a Windows 7 or 8 operating system, or Windows Server 2008 or 2012. The tools support JDK version 1.6 or higher and integrate into the Eclipse IDE for Java EE. You also need a set of Windows Azure SDK 2.0 tools that can be automatically installed when you first create a project in Eclipse.
To host applications in the cloud and run them locally, you need one of the Java application servers of your choice: Tomcat, GlassFish, Jboss, or Jetty. We will use Tomcat 7.0 in this article.
To install Windows Azure Toolkit for Eclipse, launch Eclipse and go to the menu item Help -> Install new software.
Enter http://dl.msopentech.com/eclipse in the "Work with" field. Select Windows Azure Toolkit for Eclipse from the list and click Next to customize the installation or Finish to install all the default components.
Create a "Dynamic Web Project" project in Eclipse and add a new JSP file under any name with the "New JSP File (html)" template to WebContent. Modify this file to your liking. You should have the picture shown in the picture.
Right-click on the project and select the menu item Windows Azure -> Package for Windows Azure. A wizard will prepare the placement of the project in the cloud. Enter the project name and click Next.
Make sure that the automatically set path to the local JDK location is correct and set the "Automatically upload the local JDK ..." parameter. Click "Next".
Select from the list the server option for running applications that you use locally and plan to use in the cloud. If necessary, manually set the path to this server on your disk. Select the option "Automatically upload the local server ...". Click "Next".
Make sure that the war file is added to the application list. Click "Next".
Optionally, enable one of the additional mechanisms for your cloud application: support for sticky sessions, support for caching, support for remote debugging of code. Click "Finish".
A new customized package will be created and added to Project Explorer for publishing to the Windows Azure cloud environment.
Select the package in the list and click the menu item "Run in Windows Azure Emulator"
The project will be launched in the local Windows Azure computing power emulator. The startup process will be displayed in detail in the Eclipse console.
During startup, you may see a request for permission to access the network from a UAC system, simply confirm this request. After a few seconds, your application server will start (in my case, Tomcat).
And the local emulator of computing power of Windows Azure.
Launch your browser and go to http: // localhost: 8080 / HelloWindowsAzure / NewFile.jsp - where NewFile.jsp is the name of the file you created and modified. You will see a working Java web application code ready for posting in Windows Azure.
Create an empty cloud services (Cloud Services) in Windows Azure. Stop the local code execution if the project was started and select the "Publish to Windows Azure Cloud" option.
You will need to download the Windows Azure subscription information. Click the "Import PUBLISH-SETTINGS file ..." button to import the subscription. You will be prompted to either download it from the administration portal or use the previously downloaded file from a local disk.
After downloading the configuration file and applying its parameters, the wizard will receive information about your Windows Azure subscription and download the list of subscriptions and the cloud services available in them. You can select the required publishing options:
Set all the necessary data, select the environment for placement as a production. Click the Publish button.
The process of placing the cloud service package in Windows Azure begins. Usually this process takes about a minute or two, depending on the configuration.
Open a browser and go to your cloud service to make sure the Java application is deployed and running in the Windows Azure cloud.
Now you can adjust its parameters, scale your application on demand, or specify automatic scaling parameters.
Java developers can take advantage of other features provided by the Windows Azure for Eclipse toolkit, including the use of Windows Azure service libraries, the use of remote access and debugging to cloud services, as well as other parameters and settings about which you can learn more about link on the MSDN website .
In early July, the Windows Azure Toolkit for Eclipse received an update . Among the new products are the following features:
Do not miss the previous announcements of updates to the Windows Azure platform, which are released almost every week:
For Java developers, there are a number of helpful resources in the Windows Azure cloud that I suggest you visit.
Below you will find links to resources that will help you in using the Microsoft cloud platform:

Work with Windows Azure Toolkit for Eclipse
Create a "Dynamic Web Project" project in Eclipse and add a new JSP file under any name with the "New JSP File (html)" template to WebContent. Modify this file to your liking. You should have the picture shown in the picture.
