hi!!!

your problem is the DISPLAY

Caused by: java.lang.InternalError: Can't connect to X11 window server using ':0 .0' as the value of the DISPLAY variable

SCN - 1 same machine diferents users "user1" and "sapuser"

access to X11 with "user1"

1. xhost +

2. su sapuser

passwd:xxxx

#/usr/sap/XXX/j2ee/admin/go

SCN - 1 diferents machines access to X11 with "user1" in "myhost"

(myhost)# xhost +

(myhost)# telnet sapserver

user: sapuser

passwd:xxxx

(sapserver)# export DISPLAY=myhost:0.0

(sapserver)# /usr/sap/XXX/j2ee/admin/go

note:

myhost = my ip or my name machine

Hi,

I got the same error. Could you please explain your solution a bit deeper.

Thanks,

I solved the problem by setting the environment variable to 0.

That's the way I did it:

1. switch to user n4sadm (su - n4sadm)

2. set environment variable to 0 (setenv DISPLAY )

3. start visual admin (usr/sap/N4S/DVEBMGS42/j2ee/admin/go)

I hope this will help you too.

Cheers,

Josef
