Thanks for reply, I haven't try the "host/weblogic at DLSVR.COM" service prinipal,
I still cann't find the difference betwen "host/weblogic at DLSVR.COM" and "HTTP/weblogic at DLSVR.COM" ,
but the "HTTP/weblogic at DLSVR.COM" is OK and here is my successful stdout:

It appears that your application is looking for
"host/weblogic at DLSVR.COM" service principal, but you have setup keytab
with keys for "HTTP/weblogic at DLSVR.COM" service principal. Please update
your application with the expected service principal
"HTTP/weblogic at DLSVR.COM"
