Environment

Release : 10.7 SP3

Component : APM Agents

Resolution

Should use https instead of http for port 8443:

[ERROR] [WebView] Unable to establish connection with remote resource at http://example.com:8443/apm/appmap/private/configuration/static!

 

Also this property in WebView must point to the EM jetty web server:

introscope.webview.enterprisemanager.rest.base=http://example.com:8443/apm/appmap

 

This should point to EM jetty web server: use https:8443 (double check em-jetty-config.xml to confirm the protocol/port)
