webdriver API: how to disable verbose error messages ?

Question

Running the example source at

http://code.google.com/p/selenium/wiki/GettingStarted

It runs successfully, however Eclipse throws bunch of WARNING messages. How Can I disable this from displaying ? All I really need is the last line "Page title is: Cheese! - Google Search"

HtmlUnit uses the Commons Logging. You can refer here for more details.

As quick hint, you can disable warnings by setting the following system property:

System.getProperties().put("org.apache.commons.logging.simplelog.defaultlog", "fatal");
