Hi

<b>

run

xhost + <servername> 

on your X-Server

For testing , try if

xclock

works

Dirk,

xhost + <servername>

on the client, not the server

Hi Sunil Gutta,

Do you have installed the X server on this box? (rpm -qa | grep XFree86)

Which Version of Java is installed? (java -fullversion)

Which architecture are you running on? (i386, ia64)

Best Regards,

Hannes Kuehnemund
