Issue/Introduction

When launching the Java Console with UVC WebConsole 6.10.91 from a Tomcat with SSL enabled, I see a lot of errors with UnknownHostException, does this have anything to do with Univiewer or does it come from the Tomcat / Apache certificates being used?

Example of errors:

java.net.UnknownHostException: s.*.com
java.net.UnknownHostException: *.ws.*.com
java.net.UnknownHostException: *.ws.*.com
java.net.UnknownHostException: s2.*.com
java.net.UnknownHostException: sv.*.com

at sun.security.provider.certpath.OCSP.check(Unknown Source)

java.net.UnknownHostException: javadl-esd-secure.oracle.com
 at com.sun.deploy.net.proxy.pac.PACFunctionsImpl.dnsResolveImpl(Unknown Source)

Environment

Release : 6.x

Component : DOLLAR UNIVERSE

Subcomponent: Univiewer Console

Cause

The workstation where the UVC is launched from does not resolve correctly the Servers necessary to check the OCSP stapling for the TLS certificates being used in the Tomcat / Apache web servers to which UVC Webconsole communicates with.

Resolution

Ask your network/security admins to allow traffic to those servers as explained here or disable the OCSP stapling or jar/certificates validation from workstations.

Else, you can ignore these errors as they don't affect the UVC WebConsole behavior.
