5.3.2.2.7  Distribute the Application to Other Users Now that you have verified that the application works outside of the IDE, you are ready to distribute the application and allow other users to use it. To distribute the application, perform the following operations: 1) On your system, create a zip file that contains the application JAR file (SumApp.jar) and the accompanying lib folder that contains SumLib.jar.2) Send the file to the people who will use the application. Instruct them to unpack the zip file, making sure that the SumApp.jar file and the lib folder are in the same folder.3) Instruct the users to follow the stepsRead More →

5.3.2.4   Build a Free-Form Java Project There are also project templates available for free-form Java projects. In so-called free-form proj-ects, the NetBeans IDE uses targets in an existing Ant script to build, run, clean, test and debug your application. If the Ant script does not contain targets for some of these functions, the functions are unavailable for the project. To implement these functions, you write targets either in your Ant script or in a secondary Ant script. In general, it is better to use standard With Existing Sources project templates for import-ing projects. For Eclipse projects, it is best to use the Import Project feature,Read More →

6.1  INTRODUCTION TO RUNTIME OBJECT METHOD The Java runtime object method is to develop and build database-accessing operations using run-time Java code without touching JPA Wizards and Entity classes. In other words, no object-to-relational database mapping is needed, and the project can directly access the database using Java code. As we discussed in Chapter 4, to access a database to perform a data query, the following opera-tional sequence should be followed: 1) Load and register the database driver using the DriverManager class and Driver methods.2) Establish a database connection using the Connection object.3) Create a data query statement using the createStatement() method.4) Execute the dataRead More →

6.3  CREATE A JAVA APPLICATION PROJECT TO ACCESS THE ORACLE DATABASE First let’s create a new Java application project named OracleSelectFaculty using the NetBeans IDE 12. Go to the File|New Project menu item to start this process. FIGURE 6.5   The finished New Java Application wizard. Your finished New Java Application wizard is shown in Figure 6.5. Click on the Finish button to create this new Java application project, OracleSelectFaculty. Next we need to create five JFrame Forms as our graphical user interfaces, LogInFrame, SelectionFrame, FacultyFrame, CourseFrame and StudentFrame, to perform the data queries to five data Tables in our sample database. We also need toRead More →

FIGURE 6.7   A preview of the created SelectionFrame Form. FIGURE 6.8   A preview of the finished FacultyFrame Form window. One point to be noted is that you need to remove all default items located inside the model prop-erty of the Combo Box ComboName and ComboMethod. To do that, click on the ComboName combo box from the Design View, and then go the model property and click on the three-dot extension button to open the model pane. Select all four default items, and press the Delete button from the keyboard to remove all of those items. Perform similar operations for the ComboMethod. A preview of theRead More →

Generally, the JDBC API enables users to access virtually any kind of tabular data source, such as spreadsheets or flat files, from a Java application. It also provides connectivity to a wide scope of Oracle databases. One of the most important advantages of using JDBC is that it allows users to access any kind of relational database in the same way with code, which means that the user can develop one program with the same code to access either an Oracle database or a MySQL database without code modification. The JDBC 3.0 and JDBC 4.0 specifications contain additional features, such as extensions to sup-port variousRead More →

6.3.3   Add Oracle JDBC Driver to the Project Before we can load and register a JDBC driver, first we need to add the Oracle JDBC Driver we downloaded and installed on our machine as a library file into our current project’s Libraries node to enable our project to find it when it is loaded and registered. Refer to Appendix H to get more details about downloading this JDBC driver. Perform the following steps to finish the JDBC library adding process: 1) Right-click on our project, OracleSelectFaculty, in the Projects window, and select the Properties item from the popup menu to open the Project Properties wizard.Read More →
