There are extended settings on IS to enable them, but make sure if your IS version support TLS1.2 as per my knowledge it is supported from v9.5 onwards via a core fix.
Using soap connector there were logs in wrapper.log indicating ssl:

but when I switch “useJSSE”=true on connector nothing appears in wrapper.log confirming using TLS.
In “9-7_Integration_Server_Administrators_Guide.pdf” we didn’t find any information about global settings (watt.*) for using TLS1.2 whenever it is possible. Only this:
IntegrationServer has two types of SSL/TLS Handlers: Entrust IAIK and JSSE.
Entrust IAIK version bundled with IntegrationServer only supports TLSv1.0.
For TLSv1.1 and TLSv1.2 JSSE needs to be used.
These are supported when running IntegrationServer in JVM 7 or newer.
See Empower KnowledgeBase entry referring to POODLE for details on how to configure JSSE, which is using different extended settings in comparison to Entrust. This article also contains a list of fixes which needs to be applied to get these properties working.
The JSSE provider’s tracing is switched on using a different configuration. Therefore, please add “javax.net.debug=all,java.security.debug=certpath” to the end of the “watt.config.systemProperties” property on your Extended Settings within the IS Admin page. You will then need to restart the IS.
I did what you have suggested, but it didn’t work. Here are my extended settings:
watt.config.systemProperties=mail.debug=true,javax.net.debug=all,java.security.debug=certpath
watt.net.ssl.client.useJSSE=true
watt.server.compile=/opt/webmeth3/97.1/IntegrationServer/instances/…/…/jvm/jvm/bin/javac -classpath {0} -d {1} {2}
watt.server.email.processReplyEmails=true
watt.server.url.alias.partialMatching=true
After restarting IS in /opt/webmeth3/97.1/profiles/IS_default/logs/wrapper.log there was nothing about SSL/TLS connection details.
