我们使用axis2部署了一些web服务，这些服务是在使用RAD 7.5.0创建的EAR项目上实现的.EAR部署在Websphere Application Server 7.0应用服务器上。我们在服务器上创建了一个共享库，其中包括所有使用的常用jar（包括commons-fileupload-1.2.jar），名为CommonsJar。在我们使用Tomcat Server 6.X.X的单元测试中（仅部署WAR而不是整个EAR），应用程序具有良好的功能
当应用程序部署在WAS 7上时出现问题：当我们实现Web服务客户端的存根类时，我们的Java EE客户端WAS提供以下例外：

服务器上的JVM变量的配置如下：
-Xquickstart -Xlp -Dclient.encoding.override=UTF-8 -agentlib:getClasses
有什么问题可以解决？谢谢你的建议
答案 0 :(得分：3)
查看这篇文章：
http://axis.apache.org/axis2/java/core/docs/app_server.html
查找WebSphere部分，可能您必须编辑axis2.xml配置并将参数EnableChildFirstClassLoading更改为“true”
答案 1 :(得分：1)
PARENT_LAST似乎只适用于您的部署XML的CommonsJar，尝试从管理控制台UI或使用此处提到的脚本 - Can I set the classloader policy for WebSphere in the ibm-web-bnd.xmi file?为所有Web应用启用它（请参阅部署示例。 xml也在那里查看）
