com.sun.xml.ws.spi.db.DatabindingException：未知的JAXBContext实现：class com.sun.xml.internal.bind.v2.runtime.JAXBContextImpl

Question

我们有一个使用@WebserviceProvider注释的EJB3.1无状态会话bean。 不知何故，当抛出肥皂故障异常时，我们得到以下异常。 此服务部署在weblogic 12c上，它使用Jdk 1.7。 还有其他人遇到过这个问题吗？ 你能帮忙吗。 提前致谢。

我有类似的问题，并通过修复wsdl文件中的小错误设法解决它。 我的情况是wsdl定义了两个请求和响应类型的操作。 第二个操作是使用为第一个操作定义的类型，如下例所示：

<wsdl:message name="SecondOperationRequest">
    <wsdl:part name="parameters" element="tns:FirstOperationrequestType"/>
</wsdl:message>

修好之后：

<wsdl:message name="FirstOperationRequest">
    <wsdl:part name="parameters" element="tns:FirstOperationrequestType"/>
</wsdl:message>

之前只有一个名称可以区分这些操作。
