Loading a Driver

Load the database driver before creating a database connection.

You can load the driver in the following ways:
  • Before creating a connection, implicitly load the driver in the code using the Class.forName("org.postgresql.Driver") method.
  • During the JVM startup, transfer the driver as a parameter to JVM using the java -Djdbc.drivers=org.postgresql.Driver jdbctest argument.
    • jdbctest is the name of a test application.
    • If opengaussjdbc.jar is used, change the driver class name to com.huawei.opengauss.jdbc.Driver.
