My code is
service:
public interface HelloWorldService {
public String getGreetings(String name);
public String getGreetings1(NameType name);
}
public class HelloWorldImpl implements HelloWorldService {
public String getGreetings1(NameType name) {
String firstName = name.getFirstName();
String lastName = name.getLastName();
return "Hello " + firstName + " " + lastName;
}
client:
public class ClientImpl implements Client {
private HelloWorldService helloWorldService;;
@Reference(name="helloWorldService",required=false)
public void setHelloWorldService(HelloWorldService helloWorldService) {
this.helloWorldService = helloWorldService;
}
public String getGreetings1(String firstName, String lastName) {
HelloworldFactory hwf = HelloworldFactoryImpl.INSTANCE;
NameType name = hwf.createNameType();
name.setFirstName("fddfdffd");
name.setLastName("erwe");
return helloWorldService.getGreetings1(name);
}
}
I have generated some *.class files using the XSD2Java tool and used
SDOUtil.registerStaticTypes(HelloworldFactory.class) in a servlet. When the
argument is DataObject, it will be ok.
