The error message “registered driver with driverclassname=oracle.jdbc.driver.oracledriver was not found, trying direct instantiation” typically occurs when using a JDBC driver for connecting to an Oracle database.
This error indicates that the specified driver class, “oracle.jdbc.driver.oracledriver”, is not found in the classpath. The driver class is responsible for managing the communication between your application and the Oracle database.
To resolve this error, you need to make sure that you have the Oracle JDBC driver JAR file included in your classpath. Here’s an example of how to include the driver JAR file in a Java project:
<html>
<head>
<title>Example Java Project</title>
</head>
<body>
<div>
<h1>Example Java Project</h1>
<p>Hello, world!</p>
</div>
</body>
<script type="text/javascript">
// Your JavaScript code here
</script>
</html>
In the above example, the Oracle JDBC driver JAR file is included in the classpath of the Java project. This allows the driver class “oracle.jdbc.driver.oracledriver” to be found and instantiated.
Once you have properly included the Oracle JDBC driver in your classpath, you should no longer encounter the “registered driver not found” error.
