I recently got a ssl certificate from godaddy. I created the keystore properly and put the following into my server.xml:

 <Connector port="8443" protocol="org.apache.coyote.Http11Protocol" SSLEnabled="true"
               maxThreads="200" scheme="https" secure="true" keystoreFile="C:\SSLCerts\mykeystore.keystore" keystorePass="password"
               clientAuth="false" sslProtocol="TLS" />

I originally had protocol=”HTTP/1.1″ but I was receiving an error stating that the keystoreFile and the keystorePass didn’t have a matching value. Which caused a binding error on port 8443. I ran netstat and made sure nothing is running on 8443; did some googling and found to fix that issue to change the protocol as it is above.

After adding that change I’m receiving the following error:

SEVERE: Failed to start connector [Connector[org.apache.coyote.Http11Protocol-84
43]]
LifecycleException:  service.getName(): "Catalina";  Protocol handler start fail

Does anyone have any idea what needs to be done in order to fix this?

    protocol="org.apache.coyote.Http11Protocol" is not a valid protocol. You want protocol="org.apache.coyote.http11.Http11Protocol". Note the extra http11 package you are missing.

    That will probably bring you back to the problem with your key store.
