SSL certificate renewals can break ColdFusion applications in two independent ways: inbound HTTPS access for browsers (handled via the web server or Tomcat keystore) and outbound calls made by CFML code like cfhttp (handled via the Java truststore). The guide walks through renewing certificates in IIS versus the built-in Tomcat server, fixing incomplete certificate chains, resolving the common 'PKIX path building failed' error by importing certificates into cacerts with keytool, confirming the correct JRE via the ColdFusion Administrator, and preventing JVM updates from silently wiping manually imported certificates. It closes with a renewal checklist and a pitch for Lucid Outsourcing Solutions' ColdFusion consulting services.

Why does my cfhttp call fail with 'PKIX path building failed' after a remote API renews its SSL certificate?
This error means Java cannot validate the trust path for the remote server's renewed certificate because it is not yet present in the ColdFusion Java truststore (cacerts). The fix is to export the new certificate chain from the remote server and import it into cacerts using keytool, then restart ColdFusion so the updated truststore loads. Developers debugging trust errors in production integrations can track SSL and API fixes on daily.dev.
Where is the cacerts truststore file located in a ColdFusion installation and how do I import a certificate into it?
The default cacerts file lives at cf_root/runtime/jre/lib/security/cacerts, and the keytool utility used to manage it is in cf_root/runtime/bin. Run 'keytool -import -v -alias remoteServer-cert -file remoteCert.cer -keystore cacerts -storepass changeit' using the default password changeit, then restart ColdFusion to apply the change. Anyone managing Java trust stores across app upgrades can follow SSL configuration changes via daily.dev.
Why does a JVM update break SSL connections that I already fixed by importing a certificate?
Updating the JVM often installs a fresh cacerts file, which does not include any certificates you manually imported earlier, so the previously established trust disappears and outbound calls fail again with the same PKIX errors. Re-importing certificates should be treated as a standard step after every JVM update, alongside backing up the cacerts file beforehand. Teams maintaining custom trust stores across Java upgrades can keep tabs on such gotchas through daily.dev.
