I need to somehow expose the Tomcat log files to a browser. I know that is not secure, but that's what's being requested.
I have considered making a hard link from the log location, such as tomcat/webapps/ROOT/html/catalina.out -> mydir/logs/catalina.out, but I don't think that's a good solution (even though it does work). Is there an established way of exposing Tomcat log files to a browser?

By default, the Tomcat HTTP Access Logs are stored in the dotserver/tomcat-X.x/logs/ folder within the dotCMS distribution, and the files are named dotcms_access. YYYY-MM-DD. log, where the YYYY-MM-DD in the file name is replaced by the date of the log file.
Apache Tomcat Logs Location in Windows By default, Apache Tomcat logs are stored in the install_dir/logs where the install_dir refers to the Apache Tomcat installation directory. The log files are stored in the logs directory.
Have you installed Tomcat, you can launch Monitor Tomcat tool, and start the web service, Then open a web browser, and input in the address bar the URL http://localhost:8080, then you can view Tomcat documentation or start using Tomcat.
By default, the catalina. out file is located in the logs directory under Tomcat's root directory. For example, /opt/netiq/idm/apps/tomcat/logs/catalina.
This modification to distribution configurations will expose Tomcat logs over HTTP via the services of the Tomcat DefaultServlet. Confirmed with Tomcat distributions of 7.0.56, 8.0.24.
For purposes of this example, the canonical Tomcat distribution is given to be unpacked to /opt/tomcat.
In /opt/tomcat/conf/Catalina/localhost create the file logs.xml with this content:
<Context override="true" docBase="/opt/tomcat/logs" path="/logs" />
Restart Tomcat. Browse to a log file you know is there, e.g.
If you additionally desire to be able to browse the listing of logs, suggest this additional configuration change.
Edit /opt/tomcat/conf/web.xml. Where the listings parameter is configured, turn it on by setting its value to true:
...
<servlet>
...
<init-param>
<param-name>listings</param-name>
<param-value>true</param-value>
</init-param>
...
Restart your tomcat for changes to take effect. Expect to see a list of log files as clickable links when conducting this test in a browser
These settings are likely not desirable for some production environments due to either security or performance/resource usage concerns.
