Creating Polite Long-Running Methods use javabean barcode 3/9 generator tobuild barcode code39 for java iPhone The final step i barcode code39 for Java n providing a clean shutdown is to make any long-running methods behave politely. Methods that might run for a long time should check the value of the field that notifies them of shutdowns and should interrupt their work, if necessary:. public void doPo st(...

) { ...

for(i = 0; ((i < lotsOfStuffToDo) && !isShuttingDown()); i++) { try { partOfLongRunningOperation(i); } catch (InterruptedException e) { ...

} } }. 10 Java Servlet Technology The mood Example Application The mood Example Application The mood example application, located in tut-install/examples/web/mood, is a simple example that displays Duke s moods at different times during the day. The example shows how to develop a simple application by using the @WebServlet, @WebFilter, and @WebListener annotations to create a servlet, a listener, and a filter..

Components of the mood Example Application The mood example application is comprised of three components: mood.web.MoodServlet, mood.

web.TimeOfDayFilter, and mood.web.

SimpleServletListener. MoodServlet, the presentation layer of the application, displays Duke s mood in a graphic, based on the time of day. The @WebServlet annotation specifies the URL pattern:.

@WebServlet("/re tomcat Code 3 of 9 port") public class MoodServlet extends HttpServlet { ...

. TimeOfDayFilter sets an initialization parameter indicating that Duke is awake:. @WebFilter(filte barcode code39 for Java rName = "TimeOfDayFilter", urlPatterns = {"/*"}, initParams = { @WebInitParam(name = "mood", value = "awake")}) public class TimeOfDayFilter implements Filter { ...

. The filter calls the doFilter method, which contains a switch statement that sets Duke s mood based on the current time. SimpleServletListener logs changes in the servlet s lifecycle. The log entries appear in the server log.

. Building, Packaging, Deploying, and Running the mood Example You can use either NetBeans IDE or Ant to build, package, deploy, and run the mood example. The Java EE 6 Tutorial: Basic Concepts The mood Example Application To Build, Package, Deploy, and Run the mood Example Using NetBeans IDE Select File Open 3 of 9 for Java Project. In the Open Project dialog, navigate to:. tut-install/examples/web/. 3 4 5 6 7 8. Select the mood folder. Select the Open as Main Project check box. Click Open Project.

In the Projects tab, right-click the mood project and select Build. Right-click the project and select Deploy. In a web browser, open the URL http://localhost:8080/mood/report.

The URL specifies the context root, followed by the URL pattern specified for the servlet. A web page appears with the title Servlet MoodServlet at /mood a text string describing Duke s mood, and an illustrative graphic..

To Build, Package, Deploy, and Run the mood Example Using Ant In a terminal window, go to:. tut-install/exam Code39 for Java ples/web/mood/. Type the following command:. This target buil Java 39 barcode ds the WAR file and copies it to the tut-install/examples/web/mood/dist/ directory. . Type ant deploy. Ignore the URL shown in the deploy target output. In a web browser, open the URL http://localhost:8080/mood/report.

The URL specifies the context root, followed by the URL pattern. A web page appears with the title Servlet MoodServlet at /mood a text string describing Duke s mood, and an illustrative graphic..

The Java EE 6 Tutorial: Basic Concepts P A R T I I I Web Services Part III introdu ces web services. This part contains the following chapters:. 11, Introducti 39 barcode for Java on to Web Services 12, Building Web Services with JAX-WS 13, Building RESTful Web Services with JAX-RS . This page intentionally left blank C H A P T E R Introduction to Web Services Part III of the Code39 for Java tutorial discusses Java EE 6 web services technologies. For this book, these technologies include Java API for XML Web Services (JAX-WS) and Java API for RESTful Web Services (JAX-RS). The following topics are addressed here: What Are Web Services on page 203 Types of Web Services on page 203 Deciding Which Type of Web Service to Use on page 206.

What Are Web Services Web services are javabean Code-39 client and server applications that communicate over the World Wide Web s (WWW) HyperText Transfer Protocol (HTTP). As described by the World Wide Web Consortium (W3C), web services provide a standard means of interoperating between software applications running on a variety of platforms and frameworks. Web services are characterized by their great interoperability and extensibility, as well as their machine-processable descriptions, thanks to the use of XML.

Web services can be combined in a loosely coupled way to achieve complex operations. Programs providing simple services can interact with each other to deliver sophisticated added-value services..

Types of Web Services On the conceptua jdk Code-39 l level, a service is a software component provided through a network-accessible endpoint. The service consumer and provider use messages to exchange invocation request and response information in the form of self-containing documents that make very few assumptions about the technological capabilities of the receiver..
