Hai!

I have developed one application in Java Swing.Its running well in all Windows Operating System. When I run in Linux, if I run from XTerm its running well but, when run from other terminals it gives the following error.

java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

I tried to export DISPLAY=a3:0.0
a3 is my system name
But Again I got following error

xlib: connection to "a3:0.0" refused by server
xlin: client is not authorized to connect to server


What I have to do?

Please anyone help to me!

 

 

If the "eshoppin"... classes are your classes, it looks like it might be having a problem retreiving an image?

 

 

Hi,

Do you have the DISPLAY environment variable defined in the shell you try to run java ?

can you do a echo $DISPLAY ? What does it returns ?

 

 

I set the Display environment variable like follow

export DISPLAY=a3:0.0
a3 is my system name
But I got following error

xlib: connection to "a3:0.0" refused by server
xlin: client is not authorized to connect to server


What I have to do now?

Thanks in advance
Joseph

authorise your host to connect to the one your running from with "xhost a3". This way, the connection should be enabled, but not the display. You need to import it with the display command.

The xhost command must be run from the reciever system, not the distant one.

 

 

You need to install and configure Xvfb for image processing. It is fantastic because you do not need to know any hardware settings. Here's the link that saved my day: http://www.psoft.net/ssdoc/install-linux.html#1. Follow instructions carefully. If you have any problems with installation, email me at che_blaise@yahoo.com
