in my case, the certificate was stored in one of the servers, I just do two simple steps:
1- copy the certificate to /etc/tomcat7 folder
2- Configuring the SSL Connector
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keystoreFile="/etc/tomcat7/Taikeystore.pfx"
keystorePass="1234567"
keystoreType="PKCS12" />
Done
