I have a form I want to fill in based upon some large amorphous external data. User starts typing in some text and AJAX offers suggestions. Now in the Drupal world I could do some AHAH which send the user entered data back to the server and some PHP could supply replacement bits of the form to return. (as per http://drupal.org/node/348475 and http://drupal.org/node/331941 ) But what if my code is not in PHP but in some other web enabled language like python, perl or Java.
Is there a standard way of doing this with Drupal, or should I use jQuery and avoid Drupal entirely for this.
