Re: [Php-java-bridge-users] php/java bridge and Drupal sheet node

Thanks Jost.

Sorry for the spam.  My message was getting moderated because I was "not a
member", and I thought it was because I wasn't a sourceforge member, so I
joined that, sent the message again, still got moderated, and that's when I
realized I had to be a member of the list.  Sorry for the newbiness :)

Just to clarify, I'm not writing an application in Java that I'm going to
use in PHP, at least not explicitly.  I suppose that that's essentially what
Drupal does.  To use sheetnode, I suppose I need Java functionality and
that's why I need the php/java bridge and the php/java bridge drupal module.


I understand that I'd need the include: require_once("
http://localhost:8080/JavaBridge/java/Java.inc"); if I were writing a php
app that was using Java functionality, however, I'm not sure how Drupal is
supposed to use this include.  I tried including it at the top of drupal's
index.php file and in the php_java_bridge.module file, but still see the
"PHP/Java Bridge extension is not loaded" error.  So I'm not really sure
what to do... not sure if the include should go somewhere else, or if it's
needed at all.

Thanks
