我正在尝试在 Eclipse 中创建一个 JAX-RS Web 服务。我关注了这个http://www.vogella.com/articles/REST/article.html链接。我的本地主机把这些作为我的状态报告

HTTP 状态 500：

type Exception report

message 

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

注意：Apache Tomcat/7.0.12 日志中提供了根本原因的完整堆栈跟踪。

我包括了所有的罐子，但我仍然无法达到错误点。

如果其他人遇到相同的 pb，我刚刚找到了答案：我从捆绑包中安装了球衣。但是该捆绑包缺少 asm lib。所以我下载了包含 asm lib 的 zip jersey，它可以工作。:)

我也收到与ClassVisitorASM 库相关的相同错误。

我通过添加asm-3.1.jar可从此 链接获得的 jersey 1.17.1 版本找到了解决方案。

这为我解决了上述错误。
