准备剖腹产前注意事项:servlet如何发送jpg图片到J2ME/?

不是这样么:[代码片断]
servlet:
byte[] cover = null;
try {
FileInputStream in = new FileInputStream(new File(
"c:/abc.jpg"));
cover = new byte[in.available()];
in.read(cover);
in.close();
} catch (Exception e) {
e.printStackTrace();
}
j2me:
...
Image image = Image.createImage(cover, 0, cover.length);
...
----------------------------------------------------
得到:
