Connect to Microsoft CDS from a Connection Pool in WebLogic

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

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

Deploy the JDBC Driver in WebLogic Server

To deploy the driver, add the driver JAR to your classpath. 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, prepend the path to the JAR to the WEBLOGIC_CLASSPATH environment variable in WL_HOME\common\bin\commEnv.cmd/sh. This script is located in WL_HOME\common\bin\. For example:

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

In WebLogic 12.2.1 if you want to add the driver to a specific domain, you can simply place the driver JAR and .lic file into DOMAIN_HOME\lib; for example, ORACLE_HOME\user_projects\domains\MY_DOMAIN\lib. These files will be added to the server classpath at startup.

Earlier versions require that you manually add the driver to the classpath: Prepend the following to the PRE_CLASSPATH environment variable in setDomainEnv.cmd/sh. This script is located in the bin subfolder of the folder for that domain.

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

After making these changes, restart the server.

Create a JDBC Data Source for Microsoft CDS

After deploying the driver, log into the WebLogic Administration Console and 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, cdsjdbc.
    • JNDI Name: Enter the path the JDBC data source will be bound to; for example, jdbc/CDS.
    • 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.cds.CDSDriver.
    • URL: Enter the JDBC URL. A typical JDBC URL is below:

      jdbc:cds:OrganizationUrl=https://myaccount.crm.dynamics.com/InitiateOAuth=GETANDREFRESH

      You can connect without setting any connection properties for your user credentials. Below are the minimum connection properties required to connect.

      • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
      • OrganizationUrl: Set this to the organization URL you are connecting to, such as https://myorganization.crm.dynamics.com.
      • Tenant (optional): Set this if you wish to authenticate to a different tenant than your default. This is required to work with an organization not on your default Tenant.

      When you connect the Common Data Service OAuth endpoint opens in your default browser. Log in and grant permissions. The OAuth process completes automatically.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Microsoft CDS JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.cds.jar

      Fill in the connection properties and copy the connection string to the clipboard.

    • 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 Microsoft CDS 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.
