Rxtx

Ok, i have my java rxtx program, and im having problems, i dont know what is wrong. i installed the RXTX stuff, and im getting errors.

package serial;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;
import java.io.InputStream;
import java.io.OutputStream;
import processing.app.Preferences;

public class Main {
 * *static InputStream input;
 * *static OutputStream output;

 * *public static void main(String[] args) throws Exception{
 * * * *[COLOR="Red"]Preferences.init();[/COLOR]
 * * * *System.out.println("Using port: " + Preferences.get("serial.port"));
 * * * *CommPortIdentifier portId = CommPortIdentifier.getPortIdentifier(
 * * * * * * * *Preferences.get("serial.port"));

 * * * *SerialPort port = (SerialPort)portId.open("serial talk", 4000);
 * * * *input = port.getInputStream();
 * * * *output = port.getOutputStream();
 * * * *port.setSerialPortParams(Preferences.getInteger("serial.debug_rate"),
 * * * * * * * *SerialPort.DATABITS_8,
 * * * * * * * *SerialPort.STOPBITS_1,
 * * * * * * * *SerialPort.PARITY_NONE);
 * * * *while(true){
 * * * * * *while(input.available()>0) {
 * * * * * * * *System.out.print((char)(input.read()));
 * * * * * *}
 * * * *}
 * *}
}

preferences.init() comes in and error and this is the error code it gives me when i try to run the program.

[COLOR="red"]Exception in thread "main" java.lang.RuntimeException: Uncompilable source code
 * * * *at serial.Main.main(Main.java:13)
Java Result: 1[/COLOR]

but, if i delete it, (the preferences.init()) this is the output i get is...

Using port: null
