在weblogic 12.2.1.3上创建javax.xml.ws.Service的实例时，出现NullPointerException

Question

[我们有一个由JAX-WS RI 2.2.9-b130926.1035生成的EshopService_Service类-生成的源版本：wsdl文件中的2.2。

从weblogic 12.1.2.0.0升级到12.2.1.3后，在创建Service实例时得到了该堆栈：

java.lang.NullPointerException

WSDLBoundOperationImpl是weblogic的内部类，并且在Web上没有有关该类的信息…

我们已经反编译了类WSDLBoundOperationImpl，当owner.getPortType（）返回null时，它似乎在owner.getPortType().get(this.name);上失败了。

事实是我们的WSDL不包含任何“ portType”元素，但是portType不是必需的wsdl指令，并且相同的WSDL在Weblogic 12.1.2.0.0中运行良好。

如何解决这个问题？我们无法更改wsdl文件的内容...

谢谢。

看来我已经找到了解决方法... Weblogic正在使用自己的jax ws Provider实现...但是使用https://docs.oracle.com/cd/E24329_01/web.1211/e24964/data_types.htm#WSGET348功能，您可以将javax.xml.ws.spi.Provider定义为org.apache.cxf.jaxws.spi.ProviderImpl（在我的情况下）...然后，在创建Service实例时，使用apace.cxf provider实例作为提供者...
