Requirement: Create a JDBC generic data sources in Oracle WebLogic Server.

Information: In WebLogic Server, we configure database connectivity by adding JDBC data sources to our WebLogic domain. A data source is a J2EE standard method of configuring connectivity to a database. Each WebLogic data source contains a pool of database connections. Applications look up the data source on the JNDI tree or in the local application context and then reserve a database connection with the getConnection method. Data sources and their connection pools provide connection management processes that help keep our system running efficiently.

Solution: We will use the COUNTRIES table of Oracle database XE present in the HR schema. For solution of the above requirement follow the below steps:

Step 1: Create an Oracle ADF Fusion Web Application.

Step 2: Create an ADF Business Components from tables. The ADF Business Components should contain: AppModule, CountriesEO, and CountriesVO as shown below:

Step 3: Create a demo.jsf page in the ViewController project of our application. Go to Data Control Window > ExpandAppModuledataControl > Drag and drop the CountriesVO1 collection from the Data Control to the demo.jsf page as a table as shown below:

Select the default properties in the Create table popup while creating the table as shown below and click OK.

Step 4: Start Server Instance (IntegratedWeblogicServer). To start go to Run > Click Start Server Instance (IntegratedWeblogicServer).

Step 5: Once the Server Instance starts (running) open any browser and type

http://localhost:7101/console.

Thus, it loads the log in screen of the Oracle Weblogic Server as shown below:

Step 6: Give the Username and Password to login. Thus, on successful login we will get the below page.

Step 7: Click on Data Sources of the above image of Step 6. The area is highlighted in red color. Thus, we will get the below screen:

Step 8: Click on New > Select Generic Data Source. Thus, we will get the below screen:

Step 9: Give the Name as HR and JNDI name as jdbc/HR and click Next as shown below:

Step 10: Select the Database Driver as “Oracle’s Driver (Thin) for Application Continuity; Versions:Any” and click Next as shown below:

Step 11: Again, click Next. Give the Database Name, Host Name, Port, Database Username, Password, and Confirm Password as shown below. Then click Next. Click Test Configuration. Click Next.

Step 12: Check the Servers as Default Server as shown below.

Step 13: Click Finish.

Step 14: Now go to the application and open AppModule. Click Configurations. Edit AppModuleLocal and AppModuleShared. Set the Datasource Name as jdbc/HR for both AppModuleLocal and AppModuleShared as shown below:

Step 15: Go to Application Resources. Expand Connections > Database > Delete HR connection as shown below.

Step 16: Save and run the application.

Hence, the solution to our requirement.
