提问by user3574492
I am using NetBeans 8.0 and using Apache Tomcat 7.0.56 to build a web application.
我正在使用 NetBeans 8.0 并使用 Apache Tomcat 7.0.56 来构建 Web 应用程序。
I am trying to run a simple HTML file groceryPage.htmland keep getting the following error:
我正在尝试运行一个简单的 HTML 文件groceryPage.html并不断收到以下错误：

I am fairly new to using Tomcat and NetBeans so I don't really know why it doesn't successfully build and run my app
我对使用 Tomcat 和 NetBeans 还很陌生，所以我真的不知道为什么它不能成功构建和运行我的应用程序
Any help would be appreciated.
任何帮助，将不胜感激。

It clearly says, Access is denied.
它明确地说，Access is denied。
Make sure directory and file C:\Program Files\Java\apache-tomcat-7.0.56\logs\catalina.2014-11-24.logis writable for the user who is running Tomcat.
确保目录和文件C:\Program Files\Java\apache-tomcat-7.0.56\logs\catalina.2014-11-24.log对于运行 Tomcat 的用户是可写的。

The problem can be occur because of your proxysettings. If you set manual proxyon your computer, make sure that netbeansalso setup with the sameproxysettings.(Tool > Options > Proxy Settings)
由于您的proxy设置，可能会出现此问题。如果您proxy在计算机上设置手动，请确保netbeans也使用相同的代理设置进行设置。（工具 > 选项 > 代理设置）

Change the owner of the directory of Tomcat. On Linux or BSD do this:
更改Tomcat目录的所有者。在 Linux 或 BSD 上执行以下操作：
chown -R username /usr/local/apache-tomcat-8.0/
chown -R 用户名 /usr/local/apache-tomcat-8.0/
*check which directory is the Tomcat on your distro.
*检查哪个目录是您的发行版上的Tomcat。

If you are running on a Windows machine, make sure that you right click the menu option to start Netbeans and select 'Run as Administrator'. This should solve your access issue.
如果您在 Windows 机器上运行，请确保右键单击菜单选项以启动 Netbeans 并选择“以管理员身份运行”。这应该可以解决您的访问问题。

I resolved this, changing the properties of the folder from the path from apache installation so. 1. right click over folder from apache tomcat 2. Select properties 3. Give full control in the tab security for all users or my user that going to publish the war or develop with NetBeans.
我解决了这个问题，从 apache 安装路径更改了文件夹的属性。1. 右键单击来自 apache tomcat 的文件夹 2. 选择属性 3. 为所有用户或我的用户在选项卡中完全控制将发布战争或使用 NetBeans 开发的安全性。

I resolved this similar error by carefully reading the "Apache Tomcat Server log". Your IDE should be able to cleanly display it for you. It taught me to always first read the logs when looking for the culprit.
我通过仔细阅读“Apache Tomcat 服务器日志”解决了这个类似的错误。您的 IDE 应该能够为您清晰地显示它。它教会我在寻找罪魁祸首时总是首先阅读日志。
For me, it was deploying using the @WebServletannotation and the web.xmldeployment descriptor at the same time for the same Servlet. Yet i had to choose one of the 2 options.
对我来说，它同时使用@WebServlet注释和web.xml部署描述符为同一个 Servlet 进行部署。然而，我不得不选择两个选项之一。
Whatever it maybe for your case, ALWAYS DON'Tbe afraid to read the Server logs. That is where all clues reside.
无论您的情况如何，永远不要害怕阅读服务器日志。这就是所有线索所在。
