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

这里是apache中的完整错误，

我猜这是因为在apache lib或我的axisservice lib中丢失了一些jar 实际上我把所有的球衣罐放入了轴服务器，我已经测试了轴2 - ＆gt;在eclipse中使用webservice测试资源管理器，它运行得很好但每当我从客户端尝试它时（正如我在上面的场景中所示），它都不起作用。

请提前建议，谢谢

Answer 1

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

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

Answer 2

请在maven项目中添加以下依赖项，以提供RuntimeDelegate的实现

<dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-bundle-jaxrs</artifactId>
        <version>2.7.18</version>
</dependency>

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