1 17 Copyright © 2005, Oracle. All rights reserved. Deploying Applications by Using Java Web Start

2 17-2 Copyright © 2005, Oracle. All rights reserved. Objectives After completing this lesson, you should be able to do the following: Define the architecture of Java Web Start Describe the benefits of using Java Web Start Deploy an application by using Web Start

3 17-3 Copyright © 2005, Oracle. All rights reserved. What Is Java Web Start? It is an application deployment technology based on the Java 2 platform. It launches full-featured applications via any browser on any platform, from anywhere on the Web.

4 17-4 Copyright © 2005, Oracle. All rights reserved. Running a Web Start Application 1.Request the application. 2.Launch Web Start on the local machine. 3.Download the application. 4.Launch the application (Draw). HTTP

5 17-5 Copyright © 2005, Oracle. All rights reserved. Advantages of Web Start Renders a very responsive and rich user interface Launches applications from the Start menu on the desktop Does not require browser to be running Allows applications to work offline Automatically updates applications when invoked

6 17-6 Copyright © 2005, Oracle. All rights reserved. Examining the JNLP File The JNLP files defines: The location of the application resources Information that appears while the application loads What the application resources are

7 17-7 Copyright © 2005, Oracle. All rights reserved. Deploying Applications with JDeveloper The JDeveloper Deployment Profile Wizard: Detects interclass dependencies Creates.ear,.war,.jar, or.zip files Enables you to have control over other files added to the deployed archive Enables you to save deployment profile settings in project files: –To simplify redeployment when code changes –That can be automatically updated with new classes as they are added to the project

8 17-8 Copyright © 2005, Oracle. All rights reserved. Creating the Deployment Profile File Select File > New

9 17-9 Copyright © 2005, Oracle. All rights reserved. Saving the Deployment Profile Select a destination and name for the deployment profile.

10 17-10 Copyright © 2005, Oracle. All rights reserved. Selecting Files to Deploy Select the file types to include. Other settings differ for other deployment profile types.

11 17-11 Copyright © 2005, Oracle. All rights reserved. Making an Executable.jar File Set the Main Class field to the class name containing a main() method, in JAR Options.

12 17-12 Copyright © 2005, Oracle. All rights reserved. Creating and Deploying the Archive File Right-click the Deployment Profile file. Select the Deploy to menu option. The.jar file is created in the directory listed in the deployment properties.

13 17-13 Copyright © 2005, Oracle. All rights reserved. Using JDeveloper to Deploy an Application to Java Web Start Step 1: Generate deployment profiles and archive the application. Step 2: Start OC4J and create a connection. Step 3: Use Web Start Wizard to create JNLP file. Step 4: Archive and deploy your application to OC4J server.

14 17-14 Copyright © 2005, Oracle. All rights reserved. Step 1: Generate Deployment Profiles and Archive Application Package all the Java application files into a simple.jar archive.

15 17-15 Copyright © 2005, Oracle. All rights reserved. Step 2a: Start OC4J Use the command line to start the server.

16 17-16 Copyright © 2005, Oracle. All rights reserved. Step 2b: Creating a Connection Use the Connection Wizard to create a connection to the application server. You must specify: The type of connection (OC4J) The username and password for authentication Local URL, target Web site, and local directory for OC4J

17 17-17 Copyright © 2005, Oracle. All rights reserved. Step 3: Use Web Start Wizard to Create a JNLP File Specify the Web Start name, application archive (.jar ), and main application class. Include information to be displayed to the user while downloading (for example, application title, vendor, and brief description)

18 17-18 Copyright © 2005, Oracle. All rights reserved. Step 4: Archive and Deploy the Application to the OC4J Server Specify properties of the Web components and deployment description. Deploy to the OC4J connection created in step 2. Run the generated HTML file.

19 17-19 Copyright © 2005, Oracle. All rights reserved. Summary In this module, you should have learned how to: Describe how a Java Web Start application runs Describe the benefits of using Java Web Start Use JDeveloper to deploy an application by using Web Start

20 17-20 Copyright © 2005, Oracle. All rights reserved. Practice 17: Overview This practice covers the following topics: Archiving your Java application Creating a new project to hold the Web Start files and setting the OC4J server preference Installing and starting the stand-alone OC4J application server Creating an application server connection in JDeveloper Archiving and deploying the application files to OC4J, and testing the application
