[support] I would like to be able within a Drupal module's hook do an ajax call to a Java Servlet.

Let me rephrase my question: I currently within the same server have Apache/Drupal and Apache Tomcat/Java. I would like to be able within a Drupal module's hook do an ajax call to a Java Servlet.

How would I do this within Drupal version 6?

For future reference how would I do this within Drupal version 7?

Thanks,

John

You will probably need 2 menu items:

• The first to define the page that will be the ajax client. Ie, the

url of the page that this all happens on, a regular drupal page that has called drupal_add_js() to add some JS code that will do a $.ajax({...}); call (or other jquery asynchronous call). This menu item might not be needed though if the JS is added in a block, or inserted via hook_form_alter or hook_nodeapi, etc.

• The second menu item will define the ajax server. It should be

'type'=>MENU_CALLBACK and have the appropriate access checks defined as well. The callback function associated with this path should, instead of returning themed output, end with: drupal_json(array(...)); exit(); where the array(...) is an associative array that you want to hand back to the calling page in JSON format.

If you're doing this for D7, look at: http://api.drupal.org/api/drupal/developer--examples--ajax_example--ajax_exa...
