基本上，我试图使用Rational Software Architect创建一个简单的Hello World程序。要创建服务器，我使用Tomcat和Jersey。我发现，当我创建服务器时没有将jersey jar文件放入WEB-INF / lib而是创建了一个包含所有jar文件的自定义用户库时，Tomcat会很好地编译，但是url不会加载“ Hello World”文本，只是一个404错误。我简单地做http：// localhost：8080 / 项目名 / rest / 类路径名 ，什么都不会发生。我认为是因为我在WEB-INF / lib中没有球衣文件，但是当我将球衣jar文件放在该文件夹中并尝试运行tomcat服务器时，我在本地主机上遇到了“服务器Tomcat v7.0服务器失败开始。” 错误。
请帮帮我，谢谢。

不受支持的类版本错误表明您使用的是比Tomcat安装所支持的版本更高的jersey。很有可能是因为jre版本不匹配- 您使用的球衣库需要更新的jre，但您的版本较旧
