  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。
      

  4.   

    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？
      

  5.   

    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
    <?xml version="1.0" encoding="gb2312"?>
    <vg version="460" gridsize="2" range="100,850,420,990" bordericons="3" borderstyle="1" scrollbars="3" windowstate="0" backcolor="$FFFFFF" enzoom="0" picname="&apos;&apos;" viewheight="140" viewwidth="320" winrefresh="1" wintype="2">

    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
      

  6.   

    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。
