How to add a client certificate to Tomcat?

Question

Java

Good afternoon!
Help, pliz, with the following question -
Given: there is a tomcat behind nginx, in which a certain java application is running. The application goes by ip to client servers that are open via https with self-signed certificates.
Up to this point we have been adding certificates using keytool import in the cacerts jre keystore and the application is running successfully

Question:
Is there any other way to import certificates so that tomcat understands them but store them not in cacerts.

Answer 1

There is such a miracle application InstallCert written in java. I would force him to go through the crown to your own enginx, pick up the certificate there and add it to cacerts.
