[Nagiosplug-help] Tomcat certificates

[Peter Hall]

I've been having some problems trying to get nagios to verify
certificates on two servers running tomcat. It works fine to check
certificates on other hosts running regular apache.

Running 
# ./check_http -I hostname -p 12345 -S -C 14
simply answers "ERROR: Cannot retrieve server certificate."

But if I run 
# openssl s_client -connect hostname:12345
I see the certificate just fine, connecting to the site in a browser
also shows the certificate.

Running a similar check_http command for a regular apache installation
with a SSL certificate works just fine.

I've played around with some options to check_http but can't get this to
work.

Running a wget on the host and port I noticed something interesting,
don't know if this is related or not: 

Connecting to hostname[XXX.XXX.XXX.XXX]:12345... connected.
HTTP request sent, awaiting response... 302 Moved Temporarily
Location: https://hostname:12345/index.jsp [following]

It then proceeds to download index.jsp.
Could this have anything to do with check_http not working?
What have I missed?

Thanks,
