Tomcat 8管理器部署WAR文件后无法定位文件路径求助

Hey there! I’ve dealt with this exact head-scratcher before—Debian’s packaged Tomcat splits its directories differently from the vanilla Tomcat download, which is why you couldn’t find your WAR in /etc/tomcat8 or /usr/share/tomcat*. Let’s get this sorted:

The Exact Location #

When you upload a WAR via the Tomcat 8 Manager on Debian 9, the file (and its extracted app directory) gets stored in:

/var/lib/tomcat8/webapps/

Why the Other Paths Don’t Have It #

Let’s quickly clarify what those other directories are for, so you don’t waste time looking there again:

• /etc/tomcat8/: This is only for configuration files (like server.xml, web.xml, and manager settings)
• /usr/share/tomcat*/: This holds Tomcat’s core binaries, libraries, and default documentation—your deployed apps don’t live here
• /var/lib/tomcat8/: This is Tomcat’s CATALINA_BASE directory, where all runtime data (including deployed web apps, logs, and work files) is stored

How to Confirm It’s There #

Run this command in your terminal to list the contents of the webapps directory:

ls -la /var/lib/tomcat8/webapps/

You’ll either see HelloServlet.war (the original uploaded file) or a HelloServlet/ directory (the extracted app—sometimes Tomcat removes the WAR after extraction, but the "already exists" error means the app is still tracked in this directory).

Optional: Verify via Tomcat Config #

If you want to double-check the app base path yourself, open Tomcat’s main server configuration file:

sudo nano /etc/tomcat8/server.xml

Look for the <Host> element (usually around lines 140–150). It will have an appBase attribute set to webapps, which is relative to CATALINA_BASE (/var/lib/tomcat8/), so the full path is /var/lib/tomcat8/webapps/.

If you need to re-upload a fresh version of your WAR, just delete the existing HelloServlet.war or HelloServlet/ directory from that path, then try uploading again.
