好的.有一次，我让 Tomcat (7) 工作正常.现在不是了.我不知道我可能搞砸了什么.(但我认为这是因为我在 NetBeans 中设置了一个与 Tomcat 一起工作的网络项目.)

Alright. At one point I had Tomcat (7) working fine. Now it's not. I don't know what I might have messed up. (But I think it happened as I was setting up a web-project in NetBeans to work with Tomcat.)

我使用的是 OS X 1.8.5，使用 Java 1.7.0_51.

I'm on OS X 1.8.5, using Java 1.7.0_51.

我的 catalina.out 看起来像这样:

My catalina.out looks like this:

我已经尝试重新安装Tomcat，但问题仍然存在.我会非常感谢我能得到的任何指点.

I have tried reinstalling Tomcat, but the problem persists. I'd be very thankful for any pointers I could get.

推荐答案

同样的问题发生在我身上.你可能下载了自己的 servlet.jar 文件，而不是使用 tomcat 的.检查您的/Library/Java/Extensions/文件夹(或您放置 jar 文件的任何文件夹)，并删除 servlet.jar 文件.Catalina 运行，现在应该可以运行了

Same exact problem happened to me.You probably have downloaded your own servlet.jar file instead of using tomcat's. Check out your /Library/Java/Extensions/ folder (or whatever folder you put the jar file), and delete the servlet.jar file. Catalina run, it should work now
