Question

我有以下错误：

Exception: javax.xml.soap.SOAPException: javax.xml.soap.SOAPException: Message send failed: com.sun.xml.messaging.saaj.soap.ver1_1.Message1_1Impl cannot be cast to oracle.j2ee.ws.saaj.soap.MessageImpl
    at oracle.j2ee.ws.saaj.client.p2p.HttpSOAPConnection.call2(HttpSOAPConnection.java:234)
    at oracle.j2ee.ws.saaj.client.p2p.HttpSOAPConnection.call(HttpSOAPConnection.java:141)
    at oracle.j2ee.ws.saaj.client.p2p.HttpSOAPConnection.call(HttpSOAPConnection.java:134)

我的代码是：

SOAPMessage soapMessage = MessageFactory.newInstance().createMessage();

soapMessage.getSOAPPart().getEnvelope().addNamespaceDeclaration("http://action.web.nnn.some.com/", "act");

SOAPElement elemement = soapMessage.getSOAPPart().getEnvelope().getBody().addChildElement("getSomeMethod", "http://action.web.nnn.some.com/").addChildElement("arg0");

elemement.addTextNode(someDate);

soapMessage.saveChanges();

SOAPMessage responce = SOAPConnectionFactory.newInstance().createConnection().call(soapMessage, wsdlUrl);

在：

下运行的应用程序

Java（TM）SE运行时环境（版本1.7.0_15-b33）
WebLogic Server 12.1.2.0.0

将以下行添加到setDomainEnv后出现错误：

set JAVA_OPTIONS=%JAVA_OPTIONS% -Djavax.xml.soap.MessageFactory=com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl

我正在尝试将SAAj的实现切换为saaj-impl-1.3.23.jar。

我的问题是：如何正确地要求Weblogic使用提供的SAAJ实现而不是自己的实现？

这个问题经常被问到，答案是在weblogic / application.xml文档中告诉weblogic它应该选择哪个版本：

<wls:prefer-application-packages>
   <wls:package-name>com.sun.xml.messaging.saaj.*</wls:package-name>
</wls:prefer-application-packages>

这将迫使weblogic在您的耳朵APP-INF / lib目录中使用saaj包。查看Oracle文档here
