的WebSphere Application Server/java.lang.ClassCastException

我写simole RESTful Web服务和部署的WebSphere apllication服务器上的服务，的WebSphere Application Server/java.lang.ClassCastException

，但我收到以下异常：

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

我如何解决？

谢谢。

要部署JBoss的JAX-RS实现它与冲突的（表情为主）WebSphere中包含的JAX-RS实现。

要么切换到内置的JAX-RS支持并将您的web.xml更改为引用JAX-RS类而不是实现特定的类，或将WebSphere classloader更改为PARENT_LAST以首先获取Jboss实现类路径。

如果你能做到，建议使用前者。也就是说，写入JAX-RS规范，而不是写入任何特定的实现。（这也将允许您在WebSphere下获得官方IBM对JAX-RS问题的支持。）
