Connect to ConstantContact Data from PowerBuilder

The CData JDBC Driver for ConstantContact is a standards-based control that can be used from any platform or development technology that supports JDBC, including PowerBuilder. This article shows how to use the CData JDBC Driver for ConstantContact in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for ConstantContact to retrieve data.

Connect to ConstantContact Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for ConstantContact. You can use a database profile to save connection properties. In the Database Painter, you can graphically manipulate data as well as execute SQL queries.

1. Add the driver JAR to the PowerBuilder classpath. Set the CLASSPATH system environment variable to the path to the driver JAR, located in the lib subfolder of the installation directory.

   Note: If you are using PowerBuilder Classic, you can also add the path to the driver JAR by clicking Tools -> System Options -> Java.

2. Click Tools -> Database Painter.
3. Right-click the JDBC node and click New Profile.
4. In the Database Profile Setup dialog, enter the following:
   • Profile Name: Enter a user-friendly name for the profile.
   • Driver Name: Enter the class name of the driver, cdata.jdbc.api.APIDriver
   • URL: Enter the JDBC URL.

     Start by setting the Profile connection property to the location of the ConstantContact Profile on disk (e.g. C:\profiles\ConstantContact.apip). Next, set the ProfileSettings connection property to the connection string for Profile (see below).

     ConstantContact API Profile Settings

     ConstantContact uses OAuth-based authentication.

     First, you will need to register an OAuth application with ConstantContact. You can do so from the ConstantContact API Guide (https://v3.developer.constantcontact.com/api_guide/index.html), under "MyApplications" > "New Application". Your Oauth application will be assigned a client id (API Key) and you can generate a client secret (Secret).

     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 the client_id that is specified in you app settings.
     • OAuthClientSecret: Set this to the client_secret that is specified in you app settings.
     • CallbackURL: Set this to the Redirect URI you specified in your app settings.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the ConstantContact 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. A typical JDBC URL is below:

     jdbc:api:Profile=C:\profiles\ConstantContact.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;
5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using ConstantContact Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to JDBC data sources and execute queries. The following example shows how to retrieve ConstantContact data into a DataWindow. You can add the following code to the open method:
