This topic describes how to install the OceanBase Connector/J driver and perform load and connection tests. Before the installation, make sure that the prerequisites are met.

Prerequisites

• Before you install OceanBase Connector/J, set up the basic database development environment, and make sure that the Java environment on your computer is JDK 8.

• You have obtained the installation package of the OceanBase Connector/J driver from OceanBase Technical Support.

Load the installation package

Place the JAR installation package of OceanBase Connection/J in a local directory. Use cmd to import the JAR package and then perform the following connection tests.

1. Compile the Java sample file HelloWorld.java and load the driver class.

   public class HelloWorld {
      public static void main(String[] args) {
          try {
              Class.forName("com.oceanbase.jdbc.Driver");
          } catch (Throwable e) {
              e.printStackTrace();
          }
      }
   }
   

2. Run the following command to compile the Java sample file:

   javac -cp target/oceanbase-client-{version}.jar HelloWorld.java
   

   Note

   You can change the compilation path as needed.

3. Run the following command to run the Java sample file:

   java -cp .:target/oceanbase-client-{version}.jar HelloWorld
   

If all the preceding steps are performed and no error is returned, the JAR package of the OceanBase Connector/J driver is loaded correctly.
