apache - com.sun.ws.rs.ext.RuntimeDelegateImpl 错误

Question

请帮忙
目前我正在构建一个系统，允许一些 web 服务 (Axis2) 调用 restful (jersey 1.12)
场景是这样的:

客户端 --> webservice (Axis2) --> restful services (Jersey 1.12) ...在tomcat Apache 7中运行
每当我尝试调用 Jersey 时都会出现一些问题。说

java.lang.ClassNotFoundException: com.sun.ws.rs.ext.RuntimeDelegateImpl

这里是apache中的完整错误，

我猜这是由于在 apache lib 或我的axisservice lib中丢失了一些jar
实际上我把所有的 Jersey jar 都放到了axisservice lib中
但是每当我从客户端尝试它时(如我在上面的场景中所示)它都不起作用。

请指教，提前谢谢

com.sun.ws.rs.ext 包以及 RuntimeDelegateImpl 包含在 jersey 客户端 jar 中。如果您使用的是 maven，那么将此依赖项添加到您的 pom.xml 中(这里我使用的是 jersey client v1.12):

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-client</artifactId>
    <version>1.12</version>
</dependency>
