Question

我正在尝试通过在Tomcat上运行来测试我的servlet。但是，我得到上述错误（有时会发生此错误，但早期servlet运行正常）。一些事实：

我仔细研究了this similar problem以及here和here
当我尝试重启Tomcat时（从Eclipse的“Servers”选项卡中），我从控制台获得了一些错误日志：

“严重：无法打开访问日志文件[〜\ Tomcat 7.0 \ logs \ localhost_access_log.2012-07-12.txt]”并在日志输出的最后，有“INFO：SessionListener：sessionDestroyed（' E9A6117FDF54752D80A1B9B72F2B83D3'） - 请参阅本文底部的更多信息

我在“C：\ Program Files \ Apache Software Foundation \ Tomcat 7.0 \ logs”中查看了我的日志文件，并且没有文件内容与上面第（2）项中的内容类似
我通过Eclipse部署'我的应用程序（也就是说，在开发期间，我依靠Eclipse来启动Tomcat），只有在我拥有一个稳定版本的项目时通过复制相应的java类才进行真正的部署文件到Tomcat的/ webapps / WEB-INF / classes文件夹并重启Tomcat

最重要的是， 5.键入“http://localhost:8080”会将我引导至Tomcat主页（因此我非常确定服务器正在运行），而浏览器中的“http://localhost:8080/MyProjectName/MyServlet”会导致错误显示此问题的标题。

任何想法/帮助？非常感谢你！

Answer 1

通过将适当的java类文件复制到Tomcat的/ webapps / WEB-INF / classes文件夹并重新启动Tomcat
，只有在我拥有稳定版本的项目时才进行实际部署

停在那里：你永远不应该把任何文件放到webapps/WEB-INF中，并期待它有什么好处。使用广为接受的包装（如WAR文件或爆炸WAR结构）正确部署Web应用程序到webapps目录中。

其次，问题很明显：java.io.FileNotFoundException: C:\Program Files\Apache Software Foundation\Tomcat 7.0\logs\localhost_access_log.2012-07-12.txt (Access is denied)。您的Tomcat无法写入该文件。仅仅因为你是管理员并不意味着Tomcat可以写入该目录：据我所知，Tomcat与UAC不能很好地兼容，并且你试图写入Program Files，这通常需要一些丑陋的UI凭据-entry hack。

因此，请检查您的文件（和目录）权限。检查Tomcat进程的uid：确保它们都很好。最后，请考虑使用CATALINA_HOME和CATALINA_BASE（阅读文档了解如何执行此操作）来修复所有权限问题。

java.io.FileNotFoundException：C：\ Program Files \ Apache Software Foundation \ Tomcat 7.0 \ logs \ localhost_access_log.2012-07-12.txt（访问被拒绝）
