Google Sheets JDBC Driver

Easily connect Java applications with real-time data from spreadsheets stored in Google Docs. Use Google Sheets to manage the data that powers your applications.



The Google Sheets JDBC Driver supports connection pooling: This article shows how to connect faster to Google Sheets data from Web apps in Jetty.

The CData JDBC driver for Google Sheets is easy to integrate with Java Web applications. This article shows how to efficiently connect to Google Sheets data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Google Sheets in Jetty.

Configure the JDBC Driver for Salesforce as a JNDI Data Source

Follow the steps below to connect to Salesforce from Jetty.

  1. Enable the JNDI module for your Jetty base. The following command enables JNDI from the command-line:

    java -jar ../start.jar --add-to-startd=jndi
  2. Add the CData and license file, located in the lib subfolder of the installation directory, into the lib subfolder of the context path.
  3. Declare the resource and its scope. Enter the required connection properties in the resource declaration. This example declares the Google Sheets data source at the level of the Web app, in WEB-INF\jetty-env.xml.

    <Configure id='gsheetsdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="gsheetsdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="gsheetsdemo"/></Arg> <Arg>jdbc/gsheetsdb</Arg> <Arg> <New class="cdata.jdbc.googlesheets.GoogleSheetsDriver"> <Set name="url">jdbc:googlesheets:</Set> <Set name="Spreadsheet">MySheet</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

    You can connect to a spreadsheet by providing authentication to Google and then setting the Spreadsheet connection property to the name or feed link of the spreadsheet. If you want to view a list of information about the spreadsheets in your Google Drive, execute a query to the Spreadsheets view after you authenticate.

    ClientLogin (username/password authentication) has been officially deprecated since April 20, 2012 and is now no longer available. Instead, use the OAuth 2.0 authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

    OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

    See the Getting Started chapter in the help documentation to connect to Google Sheets from different types of accounts: Google accounts, Google Apps accounts, and accounts using two-step verification.

  4. Configure the resource in the Web.xml:

    jdbc/gsheetsdb javax.sql.DataSource Container
  5. You can then access Google Sheets with a lookup to java:comp/env/jdbc/gsheetsdb: InitialContext ctx = new InitialContext(); DataSource mygsheets = (DataSource)ctx.lookup("java:comp/env/jdbc/gsheetsdb");

The steps above show how to configure the driver in a simple connection pooling scenario. For more use cases and information, see the Working with Jetty JNDI chapter in the Jetty documentation.
