© 编写 simole restful webservice 并将该服务部署在 websphere 应用服务器上，

但我得到以下异常：

Error 500: org.jboss.resteasy.spi.UnhandledException: 
    java.lang.ClassCastException: 
       org.apache.wink.common.internal.ResponseImpl incompatible with org.jboss.resteasy.core.ServerRespon

我该如何解决？

谢谢。

日志在这里：

您正在部署一个与 WebSphere 中包含的（基于 Wink 的）JAX-RS 实现冲突的 Jboss JAX-RS 实现。

切换到内置的 JAX-RS 支持并将 web.xml 更改为引用 JAX-RS 类而不是特定于实现的类，或者将 WebSphere 类加载器更改为 PARENT_LAST 以首先在类路径中获取 Jboss 实现。

如果可以的话，推荐前者。也就是说，写入 JAX-RS 规范而不是它的任何特定实现。（这也将允许您获得 IBM 对 WebSphere 下的 JAX-RS 问题的官方支持。）
