Handle headless exception in java

[de_subhadeep@hotmail.com]

Hi All,

My program is running on a headless mode and I need to set the look
and feel of my program but it gives me Headless Exception when I try
to set the look and feel.
The exception is as follows

at sun.java2d.Head lessGraphicsEnv ironment.getDef aultScreenDevic e(null:-1)
at com.sun.java.sw ing.plaf.window s.XPStyle.getIm age(null:-1)

at javax.swing.UIM anager.setLookA ndFeel(null:-1)
at javax.swing.UIM anager.setLookA ndFeel(null:-1)

Can any one tell me please how I can set the look and feel without
gettig this exception?

Thanks,
Subhadeep.

From the Sun API:

"public class HeadlessExcepti on extends UnsupportedOper ationException
Thrown when code that is dependent on a keyboard, display, or mouse is
called in an environment that does not support a keyboard, display, or
mouse."

You say you want to set the Look & Feel of an application that has no
Look & Feel... Aren't you trying to fix the tires of a boat, buying
Happy Meals without having children, calling interrupt() on a Thread
that is already dead, etc.?
