Feed OpenWeatherMap Data into FineReport

The CData JDBC Driver for OpenWeatherMap fully implements the JDBC standard and can provide OpenWeatherMap data connectivity to a wide variety of BI, reporting, and ETL tools and custom applications. In this article, we explain how to set OpenWeatherMap data as JDBC data source in FineReport and view OpenWeatherMap data as a table in the Report Designer.

Set Up a JDBC Data Source of OpenWeatherMap Data

Follow the instruction below to set OpenWeatherMap data as a FineReport database connection.

1. Copy the cdata.jdbc.api.jar file from the lib folder in the CData JDBC Driver for OpenWeatherMap installation directory to the lib folder of the FineReport installation directory. You will need to copy the cdata.jdbc.api.lic file as well.
2. From the Server tab, select Define Data Connection, click to add a new connection, and click JDBC.

Next we will set up the data connection definition in the window.

1. Database: Others
2. JDBC Driver: cdata.jdbc.api.APIDriver
3. URL: A standard JDBC connection string using semicolon-separated connection properties.

   Using API Key Authentication

   To obtain an API key, sign up for a free account at https://openweathermap.org/api and navigate to the API keys section of your dashboard. Copy your API key for use in the connection configuration.

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

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your OpenWeatherMap API key.

   Built-in Connection String Designer

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

   When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

   A typical JDBC URL is below:

    jdbc:api:Profile=C:\path\to\OpenWeatherMap.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_openweathermap_api_key";

4. Click Connection pool attributes and set Test before getting connections to No.

Click Test connection to ensure you have configured the connection properly. With the connection to OpenWeatherMap set up, you can use it as FineReport data source.

Select OpenWeatherMap Data in the Report Designer.

1. Click to add a new template data set and select DB query to open the database query window.

2. Choose the JDBC connection that you created from the dropdown list.
3. The OpenWeatherMap entities will appear as tables on the left pane.
4. Write a SELECT statement for the OpenWeatherMap data tables and columns that you want to load.
