I'm trying today for the first time to use the AMF in Red5 (usually our
app server is separate and we use OpenAMF). I have run into a problem
and searched through some red5 posts but can't see what's wrong.
When I try to invoke a method like:
import mx.remoting. *;
import mx.rpc. *;
connection = NetServices.createGatewayConnection
("http://address:5080/gateway";);
someService = connection.getService("com.some.path.to.some.Class",
this);
someService.someMethod(value, value);
The Flash IDE output says:
Error opening URL "http://address:5080/gateway";
The server says:
[ERROR] 28123 btpool1-2:( AMFGatewayServlet.serviceAMF ) Error handling
remoting call
java.lang.NullPointerException

If I comment out the call to the method, there error doesn't occur,
which tells me that the NetServices connection is actually working -
otherwise I wouldn't get anything in the server log - but maybe it's a
type translation problem.
Any ideas?
Thanks,
Bill
