Hi, I created a Java WebService implementation java file named as DeviceServiceEventBroker.java with JAX-WS annotations. My Java WebService implementation file is implements with an interface named as DeviceOmi.java of my Web Service class. And My Interface class is extends with the java.io.Serializable. I am not able to generate the wsdl from java. I got the below error. Any idea? Is there any option to use my Implemtation class with out the extends classes.
