如题。cxf-2.2.9+spring2.5 的应用。从tomcat 移植到was 7.0 上面。服务端的SOAP接口，可以正常提供服务,客户端访问页没有问题。只是在访问WSDL的时候提示异常。
http://localhost:9080/myapp/msgService?wsdl。异常信息如下

从异常信息来看 貌似是wsdl4j 在解析wsdl的时候出的问题。所以怀疑是 我应用带 wsdl4j-1.6.2.jar 与 WAS自带的wsdl4j.jar 发生了冲突。我尝试改变 应用模块的类加载策略。改为（类已装入并且是先使用本地类装入器父类最后）。改完之后。正常的应用也不能访问了报了一个404的错误。
