java - 无法在 Netbeans 中运行 Web 应用程序

Question

我在 Ubuntu 14.04 中使用 NetBeans 8.0.1，我有以下设置。我已经从 apt-get 安装了 tomcat7，并且能够通过手动创建 servlet 文件并将它们放在/webapps 文件夹中来运行简单的 servlet。

现在我想在netbeans中创建一个Web应用程序，因此我在netbeans中添加了tomcat7作为服务器，并使用netbeans提供的默认模板创建了一个Hello world项目。现在，当我运行该项目时，出现以下错误。我使用/usr/share/tomcat7 作为我的 Catalina 主目录和 Catalina 基地。但是我也尝试过/etc/tomcat7 作为我的 Catalina 基础，但随后它给出了错误，例如基础文件夹应该为空或仅包含 conf/tomcat-users.xml。

构建错误是:

The module has not been deployed. See the server log for details.

现在我检查了服务器日志，它是空的。我的服务器输出文件如下所示:

任何人都可以帮助我开始使用这个吗？

Answer 1

尝试建立一个到 tomcat 日志文件夹的符号链接(symbolic link):

sudo ln -s /var/log/tomcat7

并更改其访问权限:

sudo chmod -Rf 777 /var/log/tomcat7

希望对大家有帮助!
