之前，有些朋友從開源的WS*應用（比如說Axis、CXF）遷移到WebLogic 9、10上，經常遇到類似下面的異常：
java.lang.UnsupportedOperationException:?This?
class
?does?not?support?SAAJ?
1.3
????????at?weblogic.webservice.core.soap.SOAPElementImpl.getElementQName(SOAPElementImpl.java:

)
????????at?org.springframework.ws.soap.AbstractSoapMessage.getPayloadResult(AbstractSoapMessage.java:

)
這有一些歷史因素在內，WebLogic 8.1的WebService協議棧，包含在weblogic.jar中。
SOAP棧的全部實現，都在weblogic.webservice.core.soap.* 這個Package中。
進入了Java5的時代后，JWS依靠Annotation方式，已經徹底改變WebService編程的外觀，于是，隨之而來的是，基于Java5的WebLogic 9/10，基本上使用Sun JWS方式實現Web Services，且WebLogic開始兼容新的WS* API，WebLogic的做法是deprecated以前的WS API(weblogic.webservice.core.soap.*)，但為了8.1應用升級的兼容性考慮，用戶依然使用較舊的包。
比如上述的NotSupport異常，在默認的WebLogic 9、10中%BEA_HOME%\modules\com.bea.core.weblogic.saaj_1.0.1.0.jar其實是Support的。
對WebLogic 8.1老用戶來說，他們的WS*應用無需重新編碼即可運行在WebLogic 9.2，此時默認使用老的協議棧【weblogic.webservice.core.soap.*】
對WebLogic 9.2新用戶來說，他們也可以使用老協議棧，也可以使用新的協議棧，使用【weblogic.xml.saaj.*】
針對上述的NotSupport異常，有兩種方式可以讓應用使用新的API實現：
?System.setProperty("javax.xml.soap.MessageFactory",??"weblogic.xml.saaj.MessageFactoryImpl");
-Djavax.xml.soap.MessageFactory=weblogic.xml.saaj.MessageFactoryImpl

很好，因為它們使用了更多的API，這些API在WebLogic的老協議棧【weblogic.webservice.core.soap.*】中沒有被支持，使用新的即可。
我一般在重啟WebLogic的時候，在startWebLogic.sh腳本中加入：
-Djavax.xml.soap.MessageFactory=weblogic.webservice.core.soap.MessageFactoryImpl -Djavax.xml.soap.SOAPFactory=weblogic.webservice.core.soap.SOAPFactoryImpl
