Custom error pages on Apache Tomcat
Solution 1:
You have your page paths starting with slashes:
<error-page>
<error-code>400</error-code>
<location>**/error.html**</location>
</error-page>
<error-page>
<error-code>404</error-code>
<location>**/error.html**</location>
</error-page>
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>**/error.html**</location>
</error-page>
In this case it might be looking for them in the root of the drive.
If they are in the same folder as web.xml you can try it this way ./error.html
Other than that, I would recommend trying the full path to the file: /var/www/error/error.html
or whatever your situation is.
Solution 2:
to capture 404 for www.server.com/servlet1/SomRandomStuff
move your error.html file to $CATALINA_HOME/webapps/servlet1/error.html
. copy the error file to each of your webapp. Even though not the best way to handle this, it worked for me.
