Thanks but this would be impractical for the real application. I need to
gather
customer data and write it to the database. I would likely use POST. I
couldn't 
get POST to work either but am using _GET right now since I can at least 
see the query string value.

I need Tomcat for a Java app we run and this is the standard here.

I tried print_r( $GLOBALS ); and print_r( $HTTP_GET_VARS ) and print_r(
$HTTP_POST_VARS )
This is the output, as you can see _$HTTP_GET_VARS are empty.  THis is
perplexing......

cheers.

bummer. I have a sneaking suspicion that your problem might be related 
to the fact that you are running the cgi version of php.

one interim solution could be to write a function that fills the $_GET 
and $_POST vars - getting an array from a string like 
"var1=334343&var2=343434" is fairly trivial how does the following work 
for you?

parse_str( $_SERVER['QUERY_STRING'], $_GET );
print_r($_GET);

obviously this leaves you nowhere with POST & COOKIE values.

empty.

which of the superglobals are actually defined at all?

what does:

print_r( $GLOBALS );
print_r( $HTTP_GET_VARS );
print_r( $HTTP_POST_VARS );

...show you? (you might want to wrap the output in PRE tags for legibility)

probably a stupid question but: do you actually need tomcat? why not try 
a vanilla setup to begin with?

have you read this page:

http://nl.php.net/manual/en/language.variables.predefined.php#language.varia
bles.superglobals

if not why not? (read the manual from back to front, it save you lots of 
time in the long run)
