I try to access from a browser a simple mailing list service I developed. I adapted a working example I found but I don’t know why the request doesn’t seem to reach the service and so no response is returned.
Using a SOAP envelope is a requirement, I need to know what is possibly wrong with this code, not how I could do the same thing using other techniques. (The service is deployed correctly on a GlassFish server and I have a working Java client to test it, so no problem with the service)
Does anyone see something bad (I’m joining the WSDL too, if you need any other detail don’t hesitate)? Thanks!

I don’t get any errors in the Error Console when I’m trying to execute it on Firefox, and Internet Explorer is only displaying the Loading... and nothing more.
SOAP must be sent via a POST, not a GET.
Also, it looks like your WS-Messaging headers are wrong. In fact, I don’t even see them.
Try issuing this call using a .NET client (“Add Service Reference”), and watch on the wire with Fiddler or something like it to see what’s happening. Then do the same thing.
