private static void copy(File src, File dst) {
	try {
	    InputStream in = null;
	    OutputStream out = null;
	    try {

调用：

if (myFile != null && myFile.size() > 0) {

    File imageFile1 = new File(ServletActionContext.getServletContext().getRealPath("images") + "/" + "t01.jpg");
  
   
    if (myFile.get(0) != null) {
copy(myFile.get(0), imageFile1);
    }
}
