NoProcessorException: Couldn't create processor in Linux!

Question

Hi,
I'm trying to create processor in CentOS (kernel-2.6.18-53.1.4.el5). But i've got the following Exception:
Couldn't create processor:
javax.media.NoProcessorException: Error instantiating class: com.sun.media.processor.unknown.Handler : java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
Here is my sample code:
DataSource dataOutput = null;
Processor processor = null;
try {
     String inputfile = "file:" + System.getProperty("user.dir")
                    + File.separator + "sample.wav";
     MediaLocator locator = new MediaLocator(inputfile);
     ds = javax.media.Manager.createDataSource(locator);
     ds.connect();
     ds.start();
} catch (Exception e) {
     System.err.println("Couldn't create DataSource\n" + e);
try {
     processor = javax.media.Manager.createProcessor(ds);
} catch (NoProcessorException npe) {
     System.err.println("Couldn't create processor:\n" + npe.toString());     
}I'm not sure where is the bug in this code? Please help me with your valuable feedback.
Thanks in advance!

Hey! i've fixed the problem by installing Xvfb. :)
Xvfb (X virtual framebuffer) is an X11 server that performs all graphical operations in memory, not showing any screen output. Can run on machines with no display hardware and no physical input devices. It emulates a dumb framebuffer using virtual memory.
