Hi,
You can verify which Java version eclipse is using in the configuration tab.
Help --> About Eclipse --> Installation Details --> Configuration.
Please try the following:
..\\jre1.7.x_xx\lib\security>..\..\bin\keytool.exe -import -alias <hostname> -Keystore cacerts -file "hostname.crt"
Check your SSL connection in the browser.
Check the SSL service is up and running.
Check your server (AS Java) firewall and ports.
Good luck!
Regards,
Ridouan
