Connect to Spotify from a Connection Pool in WebLogic

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

After making these changes, restart the server.

Create a JDBC Data Source for Spotify

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, apijdbc.
   • JNDI Name: Enter the path the JDBC data source will be bound to; for example, jdbc/API.

   • 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.api.APIDriver.

   • URL: Enter the JDBC URL. A typical JDBC URL is below:

     jdbc:api:Profile=C:\profiles\Spotify.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=http://localhost:33333;

     Using OAuth Authentication

     Spotify uses OAuth 2.0 for authentication. You will need to create an application in the Spotify Developer Dashboard to obtain your client credentials.

     Setting Up Your Spotify Application

     1. Visit the Spotify Developer Dashboard.
     2. Log in with your Spotify account and click Create app.
     3. Provide an app name, description, and set a Redirect URI (e.g.,

        http://localhost:33333

        for desktop applications).
     4. Copy your Client ID and Client Secret from the app settings.

     Connection Properties

     After setting the following connection properties, you are ready to connect:

     • AuthScheme: Set this to OAuth.
     • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
     • OAuthClientId: Set this to your Spotify application's Client ID.
     • OAuthClientSecret: Set this to your Spotify application's Client Secret.
     • Scope: Set this to the required OAuth scopes (space-separated). The default includes all read scopes needed for the tables in this profile.
     • CallbackURL: Set this to the Redirect URI configured in your Spotify application (e.g., http://localhost:33333).

     Example Connection String

     Profile=C:\profiles\Spotify.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=http://localhost:33333;
     

     Available OAuth Scopes

     • user-read-private: Read access to user's subscription details and explicit content settings.
     • user-read-email: Read access to user's email address.
     • user-library-read: Read access to a user's saved tracks, albums, episodes, shows, and audiobooks.
     • playlist-read-private: Read access to user's private playlists.
     • playlist-read-collaborative: Read access to collaborative playlists the user follows.
     • user-follow-read: Read access to the list of artists the current user follows.
     • user-read-playback-state: Read access to a user's player state (device, current track, progress).
     • user-read-currently-playing: Read access to a user's currently playing content.
     • user-read-playback-history: Read access to a user's recently played tracks.
     • user-top-read: Read access to a user's top artists and tracks.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Spotify 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.

     
   • 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 Spotify 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.
