java - Tomcat:无法解析运行时描述符

Question

我尝试在 CentOS 6.3 -> Apache -> Tomcat 5.5 下部署 JAX-WS 网络服务

我用谷歌搜索了几个小时，问了我所有的 friend ，也试图在 stackoverflow 上找到解决方案，但无济于事。有人可以帮我吗？提前谢谢你。

我收到以下错误消息:

查看文档:

http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/IllegalAccessError.html 如果应用程序试图访问或修改字段，或者调用它无权访问的方法，则抛出。 通常，此错误会被编译器捕获；如果类的定义发生了不兼容的更改，则此错误只会在运行时发生。

换句话说，MetroClientTubelineAssemblyContextImpl 被编译为父类(super class) DefaultClientTubelineAssemblyContext 的一个版本的子类，但似乎在运行时发生了变化。

您可能正在发生的事情是类路径中有两个 jar，其中包含这两个类 DefaultClientTubelineAssemblyContext 或 MetroClientTubelineAssemblyContextImpl 之一。您应该寻找哪些 jar 包含这些类，并尝试只加载一个。

在应用程序 Web 存档的 WEB-INF/lib 和 $TOMCAT_HOME/lib 文件夹中查找 jars 以检查是否找到任何重复项。
