问题描述

我无法弄清楚为什么会出现此错误。我尝试清理冗余的库等等。

I am not able to figure out why I get this error. I tried cleaning up libs that are redundant and so forth.

我尝试时收到错误:

  mongo = new Mongo(host, port);

有趣的是,我可以运行我从IDE(IntelliJ)制作的任何单元测试,但是我尝试通过Tomcat运行它我得到这个:

The funny thing is that I can run any unit tests I made from IDE (IntelliJ), but when I try to run it through Tomcat I get this:

我使用的是jdk 7,tomcat 7.0.27,maven 3.0.3。

I am using jdk 7, tomcat 7.0.27, maven 3.0.3.

推荐答案

这看起来像是字节码级别的错误。也许你的tomcat服务器中有两个版本的同一个库。

That looks like an error of byte code level. Maybe you have two versions of the same library in your tomcat server.
