可能的错误是什么？在我的服务器配置中，我使用的是“使用Tomcat安装”。我必须替换server.xml、context.xml、portal-ext.properties和catalina.xml以符合我的项目规范；要使用jdbc资源等，在进行此更改后，我发现此错误…

未找到异常类。查找包含此类的库

---

确保已将所有必需的库（*.jar）放入WEB-INF/lib文件夹。

某些配置文件一定已损坏。我面对这个问题，通过取消安装并重新安装tomcat解决了这个问题。我使用Tomcat7。但您可以对任何版本使用相同的命令

sudo apt-get purge tomcat7
sudo apt-get install tomcat7

现在，当您运行服务器时，它将在几个文件中显示写入或读取失败。只需授予这些目录的写和读权限

chmod -R a+r {directory_name}
chmod -R a+w {directory_name}

现在转到tomcat文件夹，在这里链接一些文件

cd /usr/share/tomcat7
sudo ln -s /var/lib/tomcat7/conf conf
sudo ln -s /var/log/tomcat7 log
sudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy
sudo chmod -R a+rwx /usr/share/tomcat7/conf

---

这将解决所有问题

我也有同样的问题。我的配置是RHEL 7.6，Tomcat 8.5.40。我正在使用脚本安装和更新Tomcat。在初始安装之后，我需要更新tomcat/conf目录下的一些文件。当我试图重新启动tomcat时，我在catalina.out中不断得到以下信息：；问题无法恢复：

原来问题的原因是试图设置所有权和模式。我在做：

sudo chown -R tomcat:tomcat /var/lib/tomcat/conf
sudo chmod -R 600 /var/lib/tomcat/conf
sudo chmod -R 750 /var/lib/tomcat/conf/Catalina

---

如果我不是以这种方式设置权限。尽管递归方式和手动方式的最终结果（所有权和模式）完全相同，但一切都很好。这很奇怪；我希望这能帮助别人。我花了两天半的时间才找到这个问题。

检查这个portal-ext.properties你是liferay吗？用户没有提到使用*NIX系统。这个答案的假设是相反的。
