From earlier comments:

This may sound a little obvious, but have you tried explicitly setting the language to an Arabic Locale using setLanguage(...)? You can potentially also first check if the Locale is available by checking the return value of isLanguageAvailable(...)

And:

Get them from Wikipedia: ISO 3166-1 and ISO 639-1. Do note that the Locale docs say: "The language codes are two-letter lowercase ISO language codes (such as "en") as defined by ISO 639-1. The country codes are two-letter uppercase ISO country codes (such as "US") as defined by ISO 3166-1."
