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

Apache Tomcat / 7.0.12 我包括所有的罐子仍然无法达到错误点。请尽快帮忙。感谢

Answer 1

我刚刚找到了答案，以防其他人遇到同一个pb：我从捆绑中安装了球衣。但是捆绑包缺乏asm lib。所以我下载了包含asm lib的zip jersey而且它有效。：）

Answer 2

我也得到与ASM库的ClassVisitor相关的错误。

我通过为this link 提供的jersey 1.17.1版本添加asm-3.1.jar找到了解决方案。

这解决了我的上述错误。

使用Eclipse的JAX-RS
