Connect to Excel Online from a Connection Pool in WebLogic

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

The CData JDBC Driver for Excel Online enables you to follow standard procedures to integrate Excel Online data into Java Web applications. This article shows how to deploy the CData JDBC Driver for Excel Online 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.excelonline.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.excelonline.jar;%PRE_CLASSPATH%

Create a JDBC Data Source for Excel Online

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, excelonlinejdbc.
    • JDBC Name: Enter the path the JDBC data source will be bound to; for example, jdbc/ExcelOnline.
    • 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.excelonline.ExcelOnlineDriver, in this property.
    • URL: Enter the JDBC URL. A typical JDBC URL is below:

      jdbc:excelonline:

      You can connect to a workbook by providing authentication to Excel Online and then setting the following properties:

      • Workbook: Set this to the name or Id of the workbook.

        If you want to view a list of information about the available workbooks, execute a query to the Workbooks view after you authenticate.

      • UseSandbox: Set this to true if you are connecting to a workbook in a sandbox account. Otherwise, leave this blank to connect to a production account.

      You use the OAuth authentication standard to authenticate to Excel Online. See the Getting Started section in the help documentation for a guide. Getting Started also guides you through executing SQL to worksheets and ranges.

    • 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 Excel Online 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.
