Laboratoire ICAR » Plateforme TXM

The OpenLocalizedPage.getValidUrl failed to manage https links -> the non-localized page is opened instead

And a stacktrace is shown in the console at startup, after loading an HTTPS protected web page loaded by the TXM 0.8.1beta landing page.

Solution¶

*Use HttpsURLConnection.openconnection() to test "https" URLs

• don't print the stacktrace
  *print an error message with Log.fine() : "Error while testing the "https:///a/b" web page: xyz exception message"
