WebSphere Application Server/java.lang.ClassCastException

İ编写simole restful Web服务并在websphere应用服务器上部署该服务

但我得到了以下例外：

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

我怎样才能解决它

谢谢

日志如下：

您正在部署的Jboss JAX-RS实现与WebSphere中包含的（基于Wink的）JAX-RS实现冲突

要么切换到内置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，要么将WebSphere classloader更改为PARENT_LAST，以便首先在类路径中获取Jboss实现

---

如果你能做到，建议使用前者。也就是说，编写JAX-RS规范，而不是它的任何特定实现。（这还允许您获得IBM对WebSphere下JAX-RS问题的官方支持。）
