axis 好像有两套:
一:jaxws

package javax.xml.ws.soap;

public class WebServiceException extends RuntimeException
public class ProtocolException extends WebServiceException
public class SOAPFaultException extends ProtocolException

使用的SOAPFault是
import javax.xml.soap.SOAPFault;
他是saaj-api包中的


二:axiom-api
public abstract interface org.apache.axiom.soap.SOAPFault extends org.apache.axiom.om.OMElement

public class org.apache.axis2.AxisFault extends java.rmi.RemoteException

axiom-impl中实现SOAPFault， 类是SOAPFaultImpl
