  1. Building Applications with Oracle JDeveloper 10g

  2. Objectives • After completing this lesson, you should be able to do the following: • Create new projects, workspaces, and applications • Build Java applications in JDeveloper • Enhance user interface frame design • Debug an application by using JDeveloper debugger • Define classes by using JDeveloper • Describe how JDeveloper can be used to build enterprise applications

  3. What Is Oracle JDeveloper 10g? • Oracle JDeveloper 10g provides an integrated development environment (IDE). • Build, compile, and run Java applications by using Oracle JDeveloper. • Use wizards to help build source code. • View objects from many perspectives: code, structure, layout, and so on.

  4. Exploring the JDeveloper Environment Component Palette System Navigator Property Inspector Code Editor

  5. Examining Workspaces • Contain multiple projects • Enable you to view currently used objects Workspace Navigator pane Structure pane

  6. What Are Projects? • Contain related files • Manage project and environment settings • Manage compiler and debug options Project Projectfiles

  7. Creating JDeveloper Items • JDeveloper items areinvoked by selecting File > New. • They are categorized by type: • General • Business Tier • Client Tier • Database Tier • Web Tier • Create any JDeveloper element.

  8. Creating an Application Workspace • In the General category, select Application Workspace to invoke the Property pane.

  9. Specifying Project Details

  10. Selecting Additional Libraries

  11. Adding a New J2SE New J2SE definitions include: • Java executable • A classpath • A source path • A doc path

  12. Looking at the Directory Structure • JDeveloper creates and stores .java and .class files by using the following convention: • <ORACLE_HOME>\jdev\mywork • Followed by the workspacename • Followed by the project name • \classes\<package name>\ • \src\<package_name>\ • Followed by class and src files

  13. Exploring the Skeleton Java Application • Contains application and frame classes

  14. Finding Methods and Fields • Find methods and fields by using the Structure pane.

  15. Supporting Code Development with Profiler and Code Coach • Improve code quality with Code Coach. • Evaluate execution stack with Execution Sample profiler. • Examine heap memory usage with Memory profiler. • Analyze event occurrence and duration with Event profiler for: • JVM events • Business Components for Java events • Custom events

  16. Customizing JDeveloper • Customize the IDE • Look and feel • General environment • Dockable windows • Component Palette • Load preset keymaps • Rename classes and packages by using refactoring.

  17. Using the Help System

  18. Obtaining Help on a Topic Use [F1] to invoke context-specific Help.

  19. Oracle JDeveloper 10g Debugger • Helps find and fix program errors: • Run-time errors • Logic errors • Allows control of execution • Allows examination of variables

  20. Setting Breakpoints • Setting breakpoints: • Manage multiple breakpoints • Manage conditional breakpoints • Define columns displayed in window • Description • Type • Status, and so on • Control scope of action • Global > Workspace > Project

  21. Using the Debugger Windows • View Debug information: • Classes: Displays list of loaded classes and status • Watch: Evaluates and displays expressions • Monitors: Displays information about active monitors • Threads: Displays the names and statuses of all threads • Smart Data: Analyzes source code near execution point • … and more

  22. Stepping Through a Program • Step through a program by using the buttons on the Debugger toolbar: • Start the debugger. • Resume the program. • Step over a method call. • Step into a method call. • Step out of a method call. • Step to the end of the method. • Pause execution. • Stop the debugger.

  23. Watching Data and Variables • The Smart Data tab displays analyzed variables and fields. • The Data tab displays arguments, local variables, and static fields from the current context. • To watch other variables: • Select a variable in the source window and right-click. • Select Watch... at Cursor from the context menu. • View the variable in the Watch tab. • Right-click a data item to modify it.

  24. Summary • In this lesson, you should have learned how: • JDeveloper builds, debugs, and runs all types of Java applications • JDeveloper can be used to develop: • Java applications • Java servlets • JSPs • EJBs • JDeveloper can be used to build enterprise applications

  25. Practice 6: Overview • This practice covers: • Exploring the Oracle JDeveloper 10g IDE • Creating a workspace and project • Including application files from the earlier lesson
