I'm really new to processing and I am trying to use serial processing but I keep getting this error. I am trying to use code from the gizmologi.st

Here is the code just in case:
Code:

import processing.serial.*;
 
Serial myPort;
String filename = "photo.jpg";
byte[] photo = {};
Boolean readData = false;
 
void setup()
{
  println( Serial.list() );
  myPort = new Serial( this, Serial.list()[0], 38400 );
}
 
void draw()
{
  byte[] buffer = new byte[64];
  if( readData )
  {
    while( myPort.available() > 0 )
    {
	int readBytes = myPort.readBytes( buffer );
	print( "Read " );
	print( readBytes );
	println( " bytes ..." );
	for( int i = 0; i < readBytes; i++ )
	{
	  photo = append( photo, buffer[i] );
	}
    }
  }
  else
  {
    while( myPort.available() > 0 )
    {
	print( "COM Data: " );
	println( myPort.readString() );
    }
  }
}
 
void keyPressed()
{
  if( photo.length > 0 ) {
    readData = false;
    print( "Writing to disk " );
    print( photo.length );
    println( " bytes ..." );
    saveBytes( filename, photo );
    println( "DONE!" );
  }
  else {
    readData = true;
    myPort.clear();
    println( "Waiting for data ..." );
  }
}
 

I keep getting this error when trying to compile:

I'm a big time newby and any help is greatly appreciated!

This is code from sam vusen. I am trying to grab an image saved into a serial eeprom into a processing folder. I was trying to compile the file and that is where I get the error. I thought Serial.list was a command in the serial library? I will try to connect the everything and then try again.
