Java 必须如何处理ServerSOAPFaultException？它与处理SOAPFaultException有何不同？

在使用第三方Web服务时，我能够处理SOAPFaultException，例如处理sessiontimeout，但有时会产生相同的Web服务

ServerSOAPFaultException

有人能解释一下它与SOAPFaultException有什么不同，以及如何处理这个异常吗

com.sun.xml.internal.ws.fault.ServerSOAPFaultException: Client received SOAP Fault from server: Your session has timed-out. Please see the server log to find more detail regarding exact cause of the failure.
             com.sun.xml.internal.ws.fault.SOAP11Fault.getProtocolException(SOAP11Fault.java:178)
     com.sun.xml.internal.ws.fault.SOAPFaultBuilder.createException(SOAPFaultBuilder.java:116)
