java - Tomcat 7 启动问题 : Could not initialize class org. apache.tomcat.util.descriptor.DigesterFactory

标签 java tomcat

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。 (但我认为它发生在我在 NetBeans 中设置一个 Web 项目以与 Tomcat 一起工作时。)

我在 OS X 1.8.5 上，使用 Java 1.7.0_51。

我的 catalina.out 看起来像这样:

我已经尝试重新安装 Tomcat，但问题仍然存在。如果能得到任何指示，我将不胜感激。

最佳答案

同样的问题发生在我身上。你可能已经下载了你自己的 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，它现在应该可以工作了
