Vault for Apache Tomcat: https://github.com/web-servers/tomcat-vault It hides the secrets in another encrypted file, and password for that file is then in another file... So it just makes it more difficult to access the secrets, but at least they are not in plain text. -Harri -Original

Reconfiguring Tomcat application without restart

RE: Compatibility, 32 bit ..

Java 9 dropped 32-bit so it only has 64-bit by default. Maybe you have Java 8 instead of Java 9. Check this: https://www.digitalocean.com/community/tutorials/how-to-install-java-with-apt-on-ubuntu-18-04 Try using Tomcat 8.5 if you want to have 32-bit. -Harri -Original Message- From:
