Cosmos DB JDBC Driver

Cosmos DB ドキュメントデータベース連携のパワフルなJava アプリケーションを素早く作成して配布。



Use the CData JDBC Driver for Cosmos DB to connect to Cosmos DB data from Web applications running on WebLogic.

The CData JDBC Driver for Cosmos DB enables you to follow standard procedures to integrate Cosmos DB data into Java Web applications. This article shows how to deploy the CData JDBC Driver for Cosmos DB in WebLogic server.

Install the JDBC Driver in WebLogic Server

Add the driver JAR and license file to the classpath your application will be using. The .lic file must be located in the same folder as the JAR. These files are located in the lib subfolder of the installation directory.

If you want to add the driver to all domains, add the JAR to the WEBLOGIC_CLASSPATH environment variable. add the following line to the commEnv.cmd/sh script in WL_HOME\common\bin\.

set WEBLOGIC_CLASSPATH=your-installation-directory\lib\cdata.jdbc.cosmosdb.jar;%WEBLOGIC_CLASSPATH%

If you want to add the driver to a specific domain, you will need to add the JAR to the PRE_CLASSPATH environment variable. Add the following line to the setDomainEnv.cmd/sh script in the bin subfolder of the folder for that domain:

set PRE_CLASSPATH=your-installation-directory\lib\cdata.jdbc.cosmosdb.jar;%PRE_CLASSPATH%

Create a JDBC Data Source for Cosmos DB

After installing the driver, create the connection.

  1. In the Domain Structure tree, click Services -> Data Sources -> New -> Generic Data Source.
  2. On the JDBC Data Source Properties page, enter the following information:
    • Name: Enter a user-friendly name; for example, cosmosdbjdbc.
    • JDBC Name: Enter the path the JDBC data source will be bound to; for example, jdbc/CosmosDB.
    • Database Type: Select Other.

  3. Click Next to use the default options. On the last page, enter the following information and click Test Configuration:

    • Driver Class Name: Enter the driver class, cdata.jdbc.cosmosdb.CosmosDBDriver, in this property.
    • URL: Enter the JDBC URL. A typical JDBC URL is below:

      jdbc:cosmosdb:AccountEndpoint=myAccountEndpoint;AccountKey=myAccountKey;

      SQL API を使ってCosmos DB アカウントに接続するために必要な接続文字列を取得するには、Azure Portal にログインして「Azure Cosmos DB」を選択し、自分のアカウントを選択します。「Settings」セクションで、「Connection String」をクリックして次の値を設定します。

      • AccountEndpoint: 値は、Cosmos DB アカウントの「Keys」ブレードからのCosmos DB アカウントURL である必要があります。
      • AccountKey: Azure ポータルで、Cosmos DB サービスに移動してAzure Cosmos DB アカウントを選択します。リソースメニューから、 「Keys」ページに移動します。「PRIMARY KEY」値を見つけ、Token をこの値に設定します。
    • Database User Name: Enter the username, if not specified in the JDBC URL.
    • Password: Enter the password, if not specified in the JDBC URL.

After selecting the server where you want to deploy the JDBC data source, you can now connect to Cosmos DB data.

More WebLogic Integration

The steps above show how configure the driver in a simple connection pooling scenario. For more use cases and information, see the JDBC sections in the WebLogic Data Sources chapter of the Oracle Fusion Middleware documentation.
