Re: [milo-dev] ClientServerExample.java failed and fix bug ?

[Shigeru Ishida <ishida_shigeru@xxxxxxxxxxx>]

Hi Kevin,

Endpoint URLs of UaTcpStackServer is below:
-----
UaTcpStackServer startup - opc.tcp://localhost:12685/example bound to /127.0.0.1:12685 [None/None]
UaTcpStackServer startup - opc.tcp://localhost:12685/example bound to /127.0.0.1:12685 [Basic128Rsa15/SignAndEncrypt]

I tried to run ClientServerExample.java with Java8/Apache Felix 4.6.1
on Windows 7 (64bit) (using Netty 4.1.1.Final).

Regards,

--Shigeru
