Question

我试图在我的Glassfish Application Server（版本4.1.1）上使用JAX-RS资源，但我得到java.lang.NoClassDefFoundError: org/codehaus/jackson/xc/JaxbAnnotationIntrospector。我已经包含了不同版本的jackson-xc依赖，但没有任何作用。从客户端调用方法时，我收到异常。我认为值得说我甚至不想使用JAX-B。这是我的maven依赖项：

您可以验证Jackson jar是否正在部署到应用程序服务器。当Java虚拟机无法在运行时找到编译时可用的特定类时，Java中出现此错误（NoClassDefFoundError）。

java.lang.NoClassDefFoundError：org / codehaus / jackson / xc / JaxbAnnotationIntrospector
