Certificate Installation for Java Based Web Servers (Tomcat) Using Keytool
Installing SSL Certificate Chain (Root, Intermediate(s) and the End Entity)
1. Import Root Certificate
-> keytool -import -trustcacerts -alias AddTrustExternalCARoot -file AddTrustExternalCARoot.crt -keystore domain.keystore
2. Import Intermediate(s)
-> keytool -import -trustcacerts -alias intermediate_filename -file intermediate_filename.crt -keystore domain.keystore
Depending on the type of SSL certificate that was purchased, there may be more than one Intermediate certificate in the chain of trust. Please install all intermediates in numberical order until you get to the domain/end entity certificate.
In order to determine which chain of trust you have, please follow the article title Which is Root? Which is Intermediate?
Example: UTNAddTrustSGCCA.crt would become to UTNAddTrustSGCCA.

Note: Tomcat will first need an SSL Connector configured before it can accept secure connections. Please ensure this is set BEFORE the server is restarted.
