之前，有些朋友从开源的WS*应用（比如说Axis、CXF）迁移到WebLogic 9、10上，经常遇到类似下面的异常：
java.lang.UnsupportedOperationException: This
class
does not support SAAJ
1.3
at weblogic.webservice.core.soap.SOAPElementImpl.getElementQName(SOAPElementImpl.java:
651
)
at org.springframework.ws.soap.saaj.Saaj13Implementation.getName(Saaj13Implementation.java:
67
)
at org.springframework.ws.soap.saaj.SaajSoapEnvelope.getBody(SaajSoapEnvelope.java:

)
at org.springframework.ws.soap.AbstractSoapMessage.getPayloadResult(AbstractSoapMessage.java:
56
)
这有一些历史因素在内，WebLogic 8.1的WebService协议栈，包含在weblogic.jar中。
SOAP栈的全部实现，都在weblogic.webservice.core.soap.* 这个Package中。
进入了Java5的时代后，JWS依靠Annotation方式，已经彻底改变WebService编程的外观，于是，随之而来的是，基于Java5的WebLogic 9/10，基本上使用Sun JWS方式实现Web Services，且WebLogic开始兼容新的WS* API，WebLogic的做法是deprecated以前的WS API(weblogic.webservice.core.soap.*)，但为了8.1应用升级的兼容性考虑，用户依然使用较旧的包。
比如上述的NotSupport异常，在默认的WebLogic 9、10中%BEA_HOME%\modules\com.bea.core.weblogic.saaj_1.0.1.0.jar其实是Support的。
对WebLogic 8.1老用户来说，他们的WS*应用无需重新编码即可运行在WebLogic 9.2，此时默认使用老的协议栈【weblogic.webservice.core.soap.*】
对WebLogic 9.2新用户来说，他们也可以使用老协议栈，也可以使用新的协议栈，使用【weblogic.xml.saaj.*】
针对上述的NotSupport异常，有两种方式可以让应用使用新的API实现：
System.setProperty("javax.xml.soap.MessageFactory", "weblogic.xml.saaj.MessageFactoryImpl");
-Djavax.xml.soap.MessageFactory=weblogic.xml.saaj.MessageFactoryImpl
java.lang.UnsupportedOperationException: This
class
does not support
SAAJ
1.1
The actual
class
/
method in question is javax.xml.soap.Text.isComment(), which
appears to be implemented by
weblogic.webservice.core.soap.SOAPTextElement.isComment().
Stack trace is as follows:
DemoServlet received an unexpected exception:

很好，因为它们使用了更多的API，这些API在WebLogic的老协议栈【weblogic.webservice.core.soap.*】中没有被支持，使用新的即可。
我一般在重启WebLogic的时候，在startWebLogic.sh脚本中加入：
-Djavax.xml.soap.MessageFactory=weblogic.webservice.core.soap.MessageFactoryImpl -Djavax.xml.soap.SOAPFactory=weblogic.webservice.core.soap.SOAPFactoryImpl
