How to translate my drupal site in other language.
As your module is not hosted on drupal.org, the strings it uses are not available on localize.drupal.org, where they can be translated in any language available there.

As such, you need to enable the Locale module, and translate the strings on your site.  

With Drupal 7, you visit the page at admin/config/regional/translate/translate, and you get a list of untranslated strings you can translate.



In Drupal 6, a similar page is available on admin/build/translate/search.
