Recently while testing windows service developed using Java Service wrapper[JWS], we faced problem that service was not starting. The windows box was running 2012 64bit OS and IPv6 only.
when we check log for wrapper we found following doubtful lines
WARN | wrapper | 2014/10/14 05:25:08 | Unable to query network interfaces for valid HostIds. (The operation completed successfully. (0x0)) . . . DEBUG | wrapper | 2014/10/14 05:25:09 | Enqueue Event 'wrapper_start' DEBUG | wrapper | 2014/10/14 05:25:09 | Preparing to restart with mode 1. ERROR | wrapperp | 2014/10/14 05:25:09 | server socket creation failed. (An address incompatible with the requested protocol was used.

when i googled it first, I did not found any useful help. So I decided to put this blog entry so that if any one faces same issue he can found it immediately
This problem was occurred because the wrapper communicate with JVM of application via socket.JWS by default used ipv4 address to bind socket. As my machine is Ipv6 only it was failing.
The solution to this problem is to change the communication way to PIPE, which can be done by adding following property in wrapper.conf
wrapper.backend.type= PIPE
you can refer the link http://wrapper.tanukisoftware.com/doc/english/prop-backend-type.html Thanks to JWS support they are pretty quick, and ready to help.
