Oracle JDeveloper 1. Tutorials. This tutorial provides a tour of the major components in the Oracle JDeveloper 1. IDE, and shows you how they can be used to build a basic Java- based application. Using this new class, you then explore some of the features of the JDeveloper IDE, including Code Assist and the Debugger. Finally you create a page flow diagram, add a Java class as a managed bean and use the managed bean in a JSF page. Before starting this tutorial you should have access to or have installed Oracle JDeveloper 1.
You can download it from Oracle Technology Network. Install it into a directory of your choice, which, in this tutorial is referred to as JDEVELOPER. Start JDeveloper by selecting Start > Programs > < JDEVELOPER. In the Select Role dialog, select Studio Developer and click OK.

This chapter provides an overview of the new features available in Oracle Enterprise Manager Cloud Control 12c. It covers new features in Oracle Enterprise Manager.
Shaping, which is based on the role of the user, allows the JDeveloper environment to tailor itself. It does this by removing unneeded items from the menus, preferences, new gallery, and even individual fields on dialogs. Shaping can even control the default values for fields on dialogs within the tool. When you first start JDeveloper, you are prompted to select a role that describes how you are going to use JDeveloper. If you select a role of . Once loaded, the JDeveloper IDE appears. The very first time you open JDeveloper, the Start Page displays.
You can re- invoke the Start Page later by choosing Help > Start Page. Notice the various options available to help you learn about JDeveloper. Click the New Application link in the Applications window.
In the New Gallery, select the Custom Application and click OK. In the Name your application page of the Create Custom Application wizard, modify the default application name to My.

- Oracle JDeveloper 12c tutorial with step by step instructions for building a basic application, using the major components of the JDeveloper IDE.
First. Application, and make sure that the Application Package Prefix is empty. Note that the Directory Name changes accordingly.
By default all applications are stored in \JDeveloper\mywork\ directory. In the Name your project page of the wizard, change the default Project Name to My. Project, and in the list of available project features, select Java. Server Faces (JSF) and click the Add button to move it into the selected pane.
It is a view of all the objects you need while you are working. An application keeps track of all your projects while you are developing your Java programs. Applications are stored in files with the extension . When you open JDeveloper, the last application used is opened by default, so that you can resume where you left off.
In JDeveloper you always work with projects contained within an application. A JDeveloper project is a logical grouping of related files.
You can add multiple projects to an application to easily access, modify and reuse your source code. In the Applications window, projects are displayed as the second level in the hierarchy under the application. The Applications window should look like this: The Applications window is the main JDeveloper window from which you access the components of your application. By default the Applications window displays on the left side of the IDE. By default, the first category, General, is highlighted in the Categories list. The other categories enable you to work with other JDeveloper technologies to build the various tiers of an application.
In the Items list in the right- hand pane select Java Class. After the constructor, press . There are also red boxes in the right margin of the source editor. If you mouse over these boxes or over the wavy red line, a tooltip displays information about the error or errors.
You see other examples like this in the Working with Code Assist topic later in this tutorial. At the end of the line, press . However some indicators remain, showing that the syntax is still not complete. Notice that auto- completion is also accessible from the Source > Complete Statement menu option.
Add code to provide the missing return statement. In the blank line between the two curly braces that were added to the method, add the following code: Notice that when you type the first double quote symbol (. Notice also that a green box has appeared in the upper right margin to indicate that there are now no syntax errors.
Code templates are a feature of the Java Source Editor. Code templates assist you in writing code more quickly and efficiently while you are in the source editor. You can edit existing templates or create your own.
This step shows you how to use some of the existing code templates in the Dog class. There is a code template for adding a main method to a Java class.
Press . Type the letter m, and press . Type fo to restrict the list. Four templates are suggested. Notice that changing the first i variable name in the loop changes all subsequent references. Limit the loop to 3 iterations. Enter a System. out.
Place the cursor on the blank line inside the curly braces of the for loop, and type sop. Press . Add code to use the loop to display the say. Hi message. Inside the parentheses after println, enter the following code: count + my. Dog. say. Hi(). Start typing count + my.
Dog. s and JDeveloper completes the say. Hi method for you. The complete line should read: System.
Dog. say. Hi()); Right- click in the editor and select Reformat from the menu to have JDeveloper restructure your code. Your code should now look like this, with a bit more breathing room around the methods: Save your work.
Go to File > Save All, or click the Save All button in the toolbar. In code and all other cases, the file name will be in italics until it it saved. In the Applications window or in the source editor, right- click Dog.
Make from the context menu. At the bottom right of the JDeveloper IDE, the log window should show successful compilation. If the log window does not display, use Window > Log to display it ( or press . Compiling a class in JDeveloper automatically saves the . When you use the Make option to compile your class, JDeveloper saves all the files in your project.
When you run a class, it is automatically compiled and saved. The log window displays 3 counts of the 'woof Jeff' message. Code Assist examines your code in the editor and provides assistance to fix common problems. Here you use the Dog class to explore some examples of the suggestions that are offered. Create a Cat object.
At the start of the main method, just after the first curly brace, press . In the new line, enter the following code: Notice that the red wavy lines and margin indicators have again appeared. A message tells you that 'quick fixes and code assists' are available for this line. If you click on the first suggestion in the list offered, JDeveloper creates a class called Cat. On this occasion you don't want to create the Cat class immediately, so you remind yourself to do it later by setting yourself a task: press . It indicates where you have created a task.
Hover over the marker with the mouse to see what the task is. Notice that the red markers have now disappeared, to be replaced by a green marker indicating that there are no errors in your code.
Add two variables to the class. Declare two variables as follows: In the code editor, right- click and select the Generate Accessors option from the context menu. The Generate Accessors option is also available from the code editor toolbar using the Generate Accessors icon. In the Generate Accessors dialog, check the Dog box to generate Getter and Setter methods for both variables. Make sure the Notify listeners when property changes is not selected.
Notice that you can define the scope for the methods, and define other properties to be implemented in the setter methods such as involving listeners and verifying the new value. Getter and Setter methods are generated into the Dog class Right- click within the code editor and from the context menu select Source > Generate Constructor from Fields. In the Generate Constructor from Fields dialog, check the checkboxes for both fields and click OK. The new constructor method is added to your code. Although you won't use this constructor in this tutorial, you can leave it in place just to have some more interesting code in the class. Using the code editor, you can search for text and display all occurrences of the specified search criteria.
You can also use a highlighting facility that retrieves all occurrences of an object. Place your cursor in the code window and then make sure the Search option Auto Code Highlight is not selected. Select Search from the menu, and make sure there is not a check mark beside Auto Code Highlight.
If there is, then click the menu option and when you revisit it, the check will be gone. In the Search box on the left of the code editor toolbar, type name. The first instance of name found after your cursor location is highlighted in the code editor. Click the Find next arrow to move to the next occurrence of the string. Click the magnifying glass icon to view additional options and ensure the check the Highlight Occurrences option is selected.
Then, click the Find next arrow to highlight all occurrences. Notice that the search function highlights all the occurrences of . This moves you to the corresponding usage in the code. You can determine the way you want code insight to behave (when and how fast). From the main menu, select Tools > Preferences. In the Preferences dialog, expand the Code Editor node and select Code Insight. This is just one of the preferences you can set to customize your coding environment.
Click OK. You can view the definition of a variable or method without navigating to a different file or opening a new editor. Hold down the Shift key and then hover over a variable or method to show its definition in a ghost window. This feature makes it convenient to quickly view code without moving cursor focus from your current code. In the Structure window, move your mouse over one of the nodes and press the .
This way you can also display the code structure within the class structure.
