Dear Sirs,
I'm trying to invoke a stateless session EJB method from a WSIF client that 
uses a WSDL with EJB extentions without success. 
After many debug sessions it seems to me like I've found out the problem, but 
I'm not able to solve it.

The problem is located in the 
WSIFDynamicProvider_EJB.createDynamicWSIFPort(Definition, Service, Port, 
WSIFDynamicTypeMap) method.
It fails throwing a NullPointerException since the Port binding has no EJB 
binding extensebility elements. 
It has only 2 UnknownExtensibilityElement:
1. "binding" NS="http://schemas.xmlsoap.org/wsdl/ejb"
2. "typeMapping" NS="http://schemas.xmlsoap.org/wsdl/formatbinding"

so to following code snippet always returns null:

-------------------- CODE SNIPPET BEGINS --------------------------
...
for (Iterator i = exs.iterator(); i.hasNext();) {
            Object o = i.next();
            if (o instanceof EJBBinding) {
                // if so try to create EJB dynamic port instance
                WSIFPort wp = new WSIFPort_EJB(def, port, typeMap);
                Trc.exit(wp);
                return wp;
            }
        }

// otherwise return null (so other providers can be checked)
Trc.exit();
return null;
-------------------- CODE SNIPPET ENDS -------------------------

Guessing that my WSDL might be wrong I checked out the provided ejb example 
with the AddressBook.xml WSDL file, but I got the very same result. 

What's wrong with what I'm doing???

I'm attaching the WSDL I'm using: could you please check it and tell me if it 
is wrong?

Thanks in advance for your help,
