How to configure a WebLogic data source in XML format?

To configure the XML file for WebLogic data source, you need to use WebLogic Server’s Administration Console or WebLogic Scripting Tool (WLST). The following are the steps to configure using the Administration Console: 1. Open the Administration Console of WebLogic Server and log in with the administrator username and password. 2. In the left navigation pane, select “Services” -> “JDBC” -> “Data Sources”. 3. Click on “Lock & Edit” to start editing the configuration. 4. Click on “New” to create a new data source. 5. On the “Create a new JDBC Data Source” page, enter the name and JNDI name of the data source. 6. Select the database type and enter the connection information for the database (such as URL, username, and password). 7. Configure other properties of the data source, such as maximum connection count, minimum connection count, etc. 8. Click “Next” and select the server to deploy the data source on the “Targeting” page. 9. Click “Finish” to complete the configuration. 10. Click on “Activate Changes” to make the configuration effective. These steps will generate an XML element in the configuration file of WebLogic Server, which contains the configuration information of the data source.
