用。String.getBytes
而且看到的应该不是UTF8编码出来的东西，应该是Base64的。
你可以用Base64Encode和Base64Decode来处理。
至于Base64是不是处理的UTF8字节流就不知道了。

如果这些数据被传到J2ME客户端中呢？是要重新写一个BASE64解释类？

在程序里面用DOM4J解析出来,再PAINT出来就可以了

用BASE64编码解码是比较好的做法，在JDK或者网上也比较容易找到现成的算法。
#9
up 学习了
#10
是说J2ME里，不是J2SE，
#1
用。String.getBytes
而且看到的应该不是UTF8编码出来的东西，应该是Base64的。
你可以用Base64Encode和Base64Decode来处理。
至于Base64是不是处理的UTF8字节流就不知道了。

不错哦。学习了。
我还没用过。用XML保存图片数据的哦。

如果这些数据被传到J2ME客户端中呢？是要重新写一个BASE64解释类？

已知XML里面保存图片的原始数据，求还原图片的方法~
LZ贴出来的东西这是XML保存图形数据吗~~我这里倒有个例子

贴一部分吧~~这是形容一个图形的,包括他的坐标,动作,颜色等属性
在程序里面用DOM4J解析出来,再PAINT出来就可以了

用BASE64编码解码是比较好的做法，在JDK或者网上也比较容易找到现成的算法。

是说J2ME里，不是J2SE，
