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

651

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�a_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
