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

[John Mitchell]

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
