Configure the CData JDBC Driver for Microsoft OneDrive in a Connection Pool in Tomcat

Connect to Microsoft OneDrive data from a connection pool in Tomcat.

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to Microsoft OneDrive data from a connection pool in Tomcat.

Connect to Microsoft OneDrive Data through a Connection Pool in Tomcat

  1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
  2. Add a definition of the resource to the context. Specify the JDBC URL here.

    OneDrive uses the OAuth authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the OAuth section of the Help documentation for an authentication guide.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.onedrive.jar

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

    You can see the JDBC URL specified in the resource definition below.

    <Resource name="jdbc/onedrive" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.onedrive.OneDriveDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:onedrive:OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;OAuthCallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access Microsoft OneDrive data, add the code above to the context.xml in the application's META-INF directory.

    For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to Microsoft OneDrive for all applications.

  3. Add a reference to the resource to the web.xml for the application. Microsoft OneDrive data JSP jdbc/OneDrive javax.sql.DataSource Container
  4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/OneDrive"); Connection conn = ds.getConnection();
