Question

撰写simole restful webservice并在websphere应用服务器上部署该服务，

但我得到以下例外：

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

我该如何解决？

感谢。

日志在这里：

<listener>
    <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>

Answer 1

您正在部署Jboss JAX-RS实现，该实现与WebSphere中包含的（基于Wink的）JAX-RS实现相冲突。

切换到内置的JAX-RS支持并更改web.xml以引用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以使Jboss实现首先在类路径。

如果你能做到，建议使用前者。也就是说，写入JAX-RS规范而不是它的任何特定实现。（这也允许您在WebSphere下获得IBM对JAX-RS问题的官方支持。）
