javaPolarM2 is a Java automation tool that uses Selenium WebDriver to scrape and export training data from the Polar Flow website.

For a given training session it will:

• Log in to Polar Flow automatically
• Export the session files (CSV, GPX, TCX) via the Polar export API
• Scrape the training detail page — training benefit, cardio load, sport heading, pace target, phases (intervals), laps, and automatic laps
• Write all scraped data to a structured XML file on disk
• Copy the matching track file to the configured output directory
• Fill in and submit a local or remote PHP upload form

Maven — add to pom.xml:

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>4.20.0</version>
</dependency>

Gradle — add to build.gradle:

implementation 'org.seleniumhq.selenium:selenium-java:4.20.0'

ChromeDriver must match the major version of the Chromium/Chrome browser installed on your machine.

• Check your Chrome version: open Chrome → chrome://settings/help
• Download the matching ChromeDriver from: https://googlechromelabs.github.io/chrome-for-testing/
• Extract the binary and note the full path — you will need it for WEB_DRIVER_PATH below.

Open javaPolarM2.java and fill in the constants at the top of the class before running.

// Directory where output XML, CSV and GPX files are written
private static final String POLAR_FILES_PATH = "/path/to/polar/output/robotflow/";

// Absolute path to the chromedriver binary
private static final String WEB_DRIVER_PATH  = "/path/to/chromedriver";

// Directory where the browser saves downloaded files
private static final String DOWNLOADS_PATH   = "/path/to/downloads/robotflow/";

The Polar and Runkeeper URLs are correct as shipped. Only change these if the sites restructure their URLs.

private static final String URL_LOCAL_HOST  = "http://localhost/your-project/";
private static final String URL_REMOTE_HOST = "www.example.com/your/upload_form.php";

The credentials for the remote host are currently hardcoded inside openRemoteHost(). Move them to constants or an external config file before deploying.

private static String polarUser     = "your.email@example.com";
private static String polarPassword = "yourPolarPassword";
private static String polarName     = "YourName";           // used in output file names

private static String runKeeperUser     = "your.email@example.com";
private static String runKeeperPassword = "yourRunKeeperPassword";

Security note: Do not commit credentials to version control. Consider reading them from environment variables or a properties file at startup.

In main(), the training ID is currently hardcoded for testing. Switch to the dynamic version when you are ready:

// Option A – dynamic: reads the ID from the current page URL
// String trainingId = extractTrainingNumber(driver);

// Option B – hardcoded: useful for repeatable testing
String trainingId = "0000000000";   // ← replace with a real training ID

# Compile
mvn compile

# Run
mvn exec:java -Dexec.mainClass="javaPolarM2.javaPolarM2"

Or run directly from your IDE (IntelliJ IDEA, Eclipse, VS Code with the Java extension).

Logging is configured via mylogging.properties in the project root. If the file is missing, a fallback ConsoleHandler at level FINE is used automatically.

Example mylogging.properties:

handlers=java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=FINE
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
javaPolarM2.javaPolarM2.level=FINE

All output files are written to POLAR_FILES_PATH:

• The XPath selectors are tightly coupled to the current Polar Flow page layout and may break after a site update.
• The remote-host credentials in openRemoteHost() are hardcoded — move these to a config file for production use.
• loginPolarLegacy() targets an older login page layout and is kept only for reference; use loginPolar() instead.
