Did you update java independently of filemaker?
what message do you get in command line when running:
FMSADMIN START WPE
Does it say the service is already running?
Yes, It says "service is already running".
Also, I have tired restart cmd also, Still i am getting same error.
Please let me know.
You didn't answer if java was updated outside of filemaker. If so, uninstall that java update, then restart the server.
I have same issue. I have reverted back to Java8u111 for my FMS 15.0.3 and resarted the server but still have the same error when trying to view database on Web DIrect.
