I am trying to make this as simple as possible:
As an example (listed below) I have a javascript ajax call to a java servlet within my existing Apache Tomcat web application not Drupal. All that would need to be modified would that the URL have to be the full path.
Is their a way within Drupal to embed a javascript call similar to the one listed below?
Thanks,
John
<script type = "text/javascript"> function download(link){ var email = document.getElementById('email'); var xmlHttpReq = new XMLHttpRequest(); var url = 'ecommerce?command=serve&name=' + link + '&email=' + email.value; xmlHttpReq.open('post', url, true); xmlHttpReq.onreadystatechange = function() { if (xmlHttpReq.readyState != 4) { return; } else { var responseText = xmlHttpReq.responseText; return false; } } xmlHttpReq.send(null); } </script>

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...
