Java 由生成的代码引起的JAXBEException

我得到了表单的以下jaxbeexception

触发此操作的是尝试调用名为

webservicecooperationname

的web服务操作。我还看到了处理此错误的其他技巧，通常包括添加

@xmlseea

注释或调整编组和解编组的方式

在本例中，我调用的是一个Web服务，其代码由Maven基于WSDL（以及支持的模式）生成。我无法直接控制Maven生成的代码，也无法控制marshall/unmarshall调用。应用程序中的其他webservice调用似乎没有任何问题

更奇怪的是，我不能在本地服务器上复制它，尽管它发生在开发服务器上。为webservice生成的JAR是相同的，因为它包含了应用程序的其余代码

这一例外在本周突然出现（而且一直如此），我怀疑环境发生了变化，但我不确定是什么。有什么想法吗

新的观察结果：

在启动/重新启动服务器后，我第一次尝试在服务器上运行此代码时，它需要一段时间（大约一分钟）才会失败并引发异常。在那之后的每一次，异常几乎都是瞬间发生的

进一步资料：

WebSphere7.0.0.23（位于服务器上）中存在此问题，但WebSphere7.0中不存在此问题 Caused by: javax.xml.ws.WebServiceException: javax.xml.bind.JAXBException: au.com.mycompany.policyinquiry.retrieveinsurancepolicydetails.v1.RetrieveInsurancePolicyDetailsResp is not known to this context at org.apache.axis2.jaxws.ExceptionFactory.createWebServiceException(ExceptionFactory.java:175) at org.apache.axis2.jaxws.ExceptionFactory.makeWebServiceException(ExceptionFactory.java:70) at org.apache.axis2.jaxws.ExceptionFactory.makeWebServiceException(ExceptionFactory.java:128) at org.apache.axis2.jaxws.marshaller.impl.alt.DocLitBareMinimalMethodMarshaller.demarshalResponse(DocLitBareMinimalMethodMarshaller.java:158) at org.apache.axis2.jaxws.client.proxy.JAXWSProxyHandler.createResponse(JAXWSProxyHandler.java:499) at org.apache.axis2.jaxws.client.proxy.JAXWSProxyHandler.invokeSEIMethod(JAXWSProxyHandler.java:377) at org.apache.axis2.jaxws.client.proxy.JAXWSProxyHandler.invoke(JAXWSProxyHandler.java:185) at $Proxy80.retrieveInsurancePolicyDetails(Unknown Source) When the JAX-WS web service engine receives a message, it uses the JAXB engine to convert the message into java beans. The message indicates a failure occurred while converting xml into an object of type com.somecom.lib.business.xml.ComIdentifierXml. The failure indicates that the JAXB engine was not initialized with information about this user class. . In this use case, the class com.somecom.lib.business.xml.ComIdentifierXml is packaged in a JAR at the EAR level. The exception does not happen if the class is packaged in a JAR located in the WAR module's WEB-INF/lib directory.
