Connect to USPS Data in IntelliJ

Integrate connectivity to USPS data with wizards in IntelliJ.

The CData JDBC Driver for USPS enables you to access USPS as a JDBC data source, providing integration with rapid development tools in IDEs. This article shows how to use the data source configuration wizard to connect to USPS data in IntelliJ.

Create a JBDC Data Source for USPS

Follow the steps below to add the driver JAR and define connection properties required to connect to USPS data.

  1. In the Data Sources window, right-click and then click Add Data Source -> DB Data Source.
  2. In the Data Source Properties dialog that appears, the following properties are required:

    • JDBC Driver Files: Click the button next to this menu to add the JDBC Driver file cdata.jdbc.usps.jar, located in the installation directory.
    • JDBC Driver Class: In this menu, select cdata.jdbc.usps.USPSDriver from the list.
    • Database URL: Enter the connection URL in the JDBC URL property. The URL must start with jdbc:usps: and includes connection properties separated with semicolons.

      To authenticate with USPS, set the following connection properties.

      • PostageProvider: The postage provider to use to process requests. Available options are ENDICIA and STAMPS. If unspecified, this property will default to ENDICIA.
      • UseSandbox: This controls whether live or test requests are sent to the production or sandbox servers. If set to true, the Password, AccountNumber, and StampsUserId properties are ignored.
      • StampsUserId: This value is used for logging into authentication to the Stamps servers. This value is not applicable for Endicia and is optional if UseSandbox is true.
      • Password: This value is used for logging into Endicia and Stamps servers. If the postage provider is Endicia, this will be the pass phrase associated with your postage account. It is optional if UseSandbox is true.
      • AccountNumber: The shipper's account number. It is optional if UseSandbox is true.
      • PrintLabelLocation: This property is required to use the GenerateLabels or GenerateReturnLabels stored procedures. This should be set to the folder location where generated labels should be stored.

      The Cache Database

      Many of the useful task available from USPS require a lot of data. To ensure this data is easy to input and recall later, utilize a cache database to make requests. Set the cache connection properties in order to use the cache:

      • CacheLocation: The path to the cache location, for which a connection will be configured with the default cache provider. For example, C:\users\username\documents\uspscache

      As an alternative to CacheLocation, set the combination of CacheConnection and CacheProvider to configure a cache connection using a provider separate from the default.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.usps.jar

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

      A typical JDBC URL is the following:

      jdbc:usps:PostageProvider=ENDICIA; RequestId=12345; Password='abcdefghijklmnopqr'; AccountNumber='12A3B4C'

Edit and Save USPS Data

To discover schema information, right-click the data source you just created and click Refresh Tables. To query a table, right-click it and then click Open Tables Editor. You can also modify records in the Table Editor.
