Hello,

As workaround you can copy the whole "admin" directory (/usr/sap/SID/instance/j2ee/admin) to your windows system.

Then start the go.bat and connect to your Java engine. See if this is working properly.

Make sure that your SAP system is running otherwise it will not connect to your engine.

if you have the same JVM 1.4.X version installed in your windows machine you can access the drive containing the directory (/usr/sap/SID/instance/j2ee/admin) in the remote system and click on go.bat file. You don`t need to copy the whole directory.

Just to clarify.

with ./go you try to start the visual admin. It is a graphical administration tool for WebAS Java.

The error you post depends on a problem with your graphical output on your system.

Hi,

do you set your DISPLAY variable correct?

Do you try to start it on the server console or you connected with a ssh/remote shell/telnet connection?

Could you start another x application like xclock?

Kind Regard

Hi,

I think this is error in your local machine. To check whether your java engine is running or not use the MMC console:

http://server:5XX13

Check the server0.log file if your server process is not started or check your dev0 files and post it here.

Vamshi.
