每当我尝试用Jersey运行Tomcat时，它都拒绝加载

标签： java rest tomcat jersey

基本上我正在尝试使用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而是我创建了一个包含所有jar文件的自定义用户库，Tomcat将编译正常但是url不会加载“Hello World”文本，只是404错误。我简单地做http://localhost:8080/ 项目名称 / rest / 类路径名，什么都不会出现。我认为它是因为我没有WEB-INF / lib中的泽西文件，但是当我将jersey jar文件放在该文件夹中并尝试运行tomcat服务器时，我得到一个“localhost上的服务器Tomcat v7.0服务器失败”开始。”错误。

请提前帮助我，并提前致谢。

我终于明白了。谢谢Sasikanth你对我的错误是正确的。 jre必须匹配apache，你的项目和Jersey。最新的Jersey使用jre7所以当你安装apache时，使用jre7作为构建路径。我的Rational项目也默认为java 1.6而不是1.7。因此，您必须手动创建jre7的构建路径。该视频教你如何做到这一点（只需在项目属性中转到java构建路径，双击jre系统库，单击已安装的jres，然后添加一个到jre目录的新路径）。要查找jre目录，只需在开始菜单中查找java，单击java选项卡，然后单击view。这使我的项目构建路径jre7，tomcat应该已经安装了jre7，并且jersey也是jre7所以一切都匹配，你的服务器将正常运行。

不受支持的类版本错误表明您使用的是比tomcat安装支持的更新版本的jersey。很可能是因为jre版本不匹配 - 你使用的球衣库需要更新的jre但是你的版本较旧
