Configure the CData JDBC Driver for Webflow in 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 Webflow data from a connection pool in Tomcat.

Connect to Webflow 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.

   Authentication

   Webflow uses OAuth 2.0 authentication to ensure secure access to sites, CMS collections, e-commerce data, and other resources. This authentication method allows you to securely connect to your Webflow workspace and manage resources with proper authorization.

   OAuth 2.0 Setup and Configuration

   Step 1: Create a Webflow OAuth Application

   To set up OAuth authentication:

   1. Visit the Webflow Developer Portal
   2. Navigate to "Apps & Integrations" in your Webflow account
   3. Click "Register an App" to create a new OAuth application
   4. Configure the application name, description, and redirect URI (CallbackURL)
   5. Copy the Client ID and Client Secret for use in your connection

   Required Connection Properties

   • AuthScheme: Set this to OAuth (required)
   • OAuthClientId: Client ID from your Webflow OAuth application (required)
   • OAuthClientSecret: Client secret from your Webflow OAuth application (required)
   • CallbackURL: Redirect URI specified in your OAuth application (required)
   • InitiateOAuth: Set to GETANDREFRESH for automatic token management (recommended)

   Required OAuth Scopes

   The Webflow API Profile requires the following OAuth scopes:

   • sites:read - Read access to site information and configuration
   • pages:read - Read access to site pages
   • cms:read - Read access to CMS collections and items
   • forms:read - Read access to forms and form submissions
   • assets:read - Read access to media assets and folders
   • ecommerce:read - Read access to products, orders, and inventory
   • authorized_user:read - Read access to the authorized user

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.api.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/api"   auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.api.APIDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:api:Profile=C:\profiles\Webflow.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;" maxActive="20" maxIdle="10" maxWait="-1" />
   

   To allow a single application to access Webflow 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 Webflow for all applications.

3. Add a reference to the resource to the web.xml for the application.

   
     Webflow data JSP
     jdbc/API
     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/API");
   Connection conn = ds.getConnection();
