I’m trying to open an URI with Swing that I get above error.

What is the reason and how can I fix it?

When I do it in console everything is OK but when I do in GUI I get this error.
I should say that I use Weblogic as server.

Code

private static void open(URI uri) {
    if (Desktop.isDesktopSupported()) {
        try {
            Desktop.getDesktop().browse(uri);
        } catch (IOException e) { /* TODO: error handling */ }
    } else { /* TODO: error handling */ }
}
