From an HL7 messaging perspective, an Application is a consumer of a messages. Once a parser parses an incoming message, the message would normally be forwarded to an Application of some sort (e.g. a lab system) which would process the message in some way meaningful for it, and then return a response.
If you are wondering how to integrate HAPI into an existing server application, this is probably the place. Create a class that implements Application, then look at Responder and SimpleServer to see how to get HAPI to listen for messages on a socket and pass them to your Application.

Base class required for all Vaadin applications. This class provides all the basic services required by Vaadin. These services allow external discovery and manipulation of the user, {@link com.vaadin.ui.Window windows} andthemes, and starting and stopping the application.
As mentioned, all Vaadin applications must inherit this class. However, this is almost all of what one needs to do to create a fully functional application. The only thing a class inheriting the Application needs to do is implement the init method where it creates the windows it needs to perform its function. Note that all applications must have at least one window: the main window. The first unnamed window constructed by an application automatically becomes the main window which behaves just like other windows with one exception: when accessing windows using URLs the main window corresponds to the application URL whereas other windows correspond to a URL gotten by catenating the window's name to the application URL.
See the class com.vaadin.demo.HelloWorld for a simple example of a fully working application.
Window access. Application provides methods to list, add and remove the windows it contains.
Execution control. This class includes method to start and finish the execution of the application. Being finished means basically that no windows will be available from the application anymore.
Theme selection. The theme selection process allows a theme to be specified at three different levels. When a window's theme needs to be found out, the window itself is queried for a preferred theme. If the window does not prefer a specific theme, the application containing the window is queried. If neither the application prefers a theme, the default theme for the {@link com.vaadin.terminal.Terminal terminal} is used. The terminalalways defines a default theme.

Application interface is an attempt to create common classes and interfaces (the package de.sciss.app) which can be shared by different programmes, such as Meloncillo or FScape, without having to make adjustments in different places each time a modification is made. This interface describes the most prominent methods needed for a general GUI based application.

Application class represents a Flex application. It implements the Builder interface which allows for building the application incrementally. There are many ways to define a Flex application. The most common way is specify the location of the target source file on disk: Application app = new Application(new File("MyApp.mxml")); Before the Application object starts the compilation, it must be configured. The most common methods that the client calls are setLogger(), setConfiguration(), and setOutput(). A logger must implement flex2.tools.oem.Logger and use the implementation as the Logger for the compilation. The following is an example Logger implementation: app.setLogger(new flex2.tools.oem.Logger() { public void log(Message message, int errorCode, String source) { System.out.println(message); } }); To specify compiler options for the Application object, the client must get a Configuration object populated with default values. Then, the client can set compiler options programmatically. The setOutput() method lets clients specify where the Application object should write the output to. If you call the setOutput() method, the build(boolean) method builds and writes directly to the location specified by the setOutput() method. For example: app.setOutput(new File("MyApp.swf")); app.build(true); If you do not call the setOutput() method, the client can use the build(OutputStream, boolean) method which requires the client to provide a buffered output stream. For example: app.build(new BufferedOutputStream(new FileOutputStream("MyApp.swf")), true); Before the Application object is thrown away, it is possible to save the compilation data for reuse by using the save(OutputStream) method. Subsequent compilations can use the load(OutputStream) method to get the old data into the Application object. app.save(new BufferedOutputStream(new FileOutputStream("MyApp.incr"))); When a cache file (such as MyApp.incr) is available from a previous compilation, the client can call the load(OutputStream) method before calling the build(boolean) method. For example: app.load(new BufferedInputStream(FileInputStream("MyApp.incr"))); app.build(); The build(false) and build(OutputStream, false) methods always rebuild the application. If the Application object is new, the first build(true)/build(OutputStream, true) method call performs a full build, which is equivalent to build(false)/build(OutputStream, false), respectively. After a call to the clean() method, the Application object always performs a full build. The clean() method not only cleans up compilation data in the Application object, but also the output file if the setOutput() method was called.
The Application class also supports building applications from a combination of source files from the file system and in-memory, dynamically-generated source objects. The client must use the Application(String, VirtualLocalFile) or Application(String, VirtualLocalFile[]) constructors.
The Application class can be part of a Project. For more information, see the Project class's description.

Application represents a per-web-application singleton object where applications based on JavaServer Faces (or implementations wishing to provide extended functionality) can register application-wide singletons that provide functionality required by JavaServer Faces. Default implementations of each object are provided for cases where the application does not choose to customize the behavior.
The instance of {@link Application} is created by calling thegetApplication() method of {@link ApplicationFactory}. Because this instance is shared, it must be implemented in a thread-safe manner.
The application also acts as a factory for several types of Objects specified in the Faces Configuration file. Please see {@link Application#createComponent}, {@link Application#createConverter}, and {@link Application#createValidator}.
The implementation-created instance of an Application subclass may be injected into resource classes and providers using {@link javax.ws.rs.core.Context}.
In case any of the {@code Application} subclass methods or it's constructorthrows a {@link RuntimeException}, the deployment of the application SHOULD be aborted with a failure.

The application provides a point of reference and context for an entire application. It provides an interface to open application windows. @author Keith Donald
Application creation is handled by the framework engine.
