  1. There is no java language either in WebDriver Sampler or in JSR223 Test Elements, when you choose java in the language drop-down the script will be evaluated by Beanshell interpreter. If you're looking for the closest to Java syntax - go for groovy

  2. There is no need to define an "entry point", the interpreter reads the script at once and executes line-by-line. You can have classes if you want. You can have main() function if you want but you will need to explicitly call it.

  3. There a pre-defined WebDriver instance WDS.browser so the minimal test would be something like:

    WDS.sampleResult.sampleStart()
WDS.browser.get('http://example.com')
WDS.sampleResult.sampleEnd()
