Been pulling m hair out today with ColdFusion…. I kept getting this error with Cfhttp “I/O Exception: peer not authenticated” I knew that it had to do with the fact I was making a call to HTTPS and I needed to import the certificate. I also remembered how to do it:

– Go to the URL in Internet Explorer
– Click the lock
– Click on Copy to file
– Save as DER to a *.cer file
– Run the Keytool C:\CFusionMX\runtime\jre\lib\security>..\..\bin\keytool -import -trustcacerts -keystore cacerts -storepass changeit -noprompt -alias mycert -file mycert.cer

But the part where I was failing was actually going to the directory where the carcerts file was, I went into the directory where the keytool was and ran the command, this actually creates a whole new cacerts file which I was not aware of….. After re-installing ColdFusion several times and running the import I finally figured it out.

IMPORTANT
Make sure you are in the directory where the cacerts file is located, which is under C:\CFusionMX\runtime\jre\lib\security or C:\JRun4\jre\lib\security

I hope this helps someone before they go and re-install ColdFusion :-) Let me know..
