Hi
Can someone help me with this please?
The function returning a List without any generic.
public List getAnyClass(@WebParam(name = "gid")String gid);
We would like to have it this way because we have 55 classes, many of which do
not have a common parent class that we can use in the generics for List<...>.
We cannot use an interface either, because it does not seem to work.
We are declaring all the classes using
props.put("jaxb.additionalContextClasses", classes);
and these classes appear in the WSDL.
Regards
Rahul

Your suggestion works to an extent, but the following codebase still gives
problems:

public String gid;
public String Name;
}
public class Employee implements Serializable {
private static final long serialVersionUID = 1L;
public String gid;
public String lastName;
public String firstName;
public Set privileges;

@WebService
public interface AuthService {
//Can contain any serializable class

}
@WebService(endpointInterface = "com.company.auth.service.AuthService",
serviceName = "corporateAuthService")

List Employees = client.getAnyClass("0223938");

System.exit(0);

}
I get the following exception:

Kindly advice.

Are you using ServerFactoryBean or are you using a JAX-WS
style "Endpoint.publish"?
Basically, you need to set the property:
jaxb.additionalContextClasses
to a Class[].
For that ServerFactoryBean stuff, just call:
Class classes[] = .......
bean.getProperties().put("jaxb.additionalContextClasses"
classes);
before you call create().
For the other case, I'm not sure, but I think you do:
Endpoint ep = Endpoint.create(....);
ep.setProperty("jaxb.additionalContextClasses"
classes);
ep.publish(...);
Alternatively, we do have samples in the docs on how to set the databinding
programmaticly (look in the Aegis databinding section). You can create your
own instance of JAXBDataBinding, call the setAdditionalClass(...) method, set
that into the factory, etc....
