Nokia E71摄像头程序无法安装jar

[haoweishow01]

下面的代码是从sun的官网上下载的。我在NetBeans6.8上建立项目，拷贝这两个文件，然后直接部署到手机上，安装的时候报无效的Jar.
各位大侠知道是什么原因吗？
或者告诉小弟，怎么才能在s60 v3版本里控制摄像头呢？

谢谢啦,另外帖子内容太长，删除了一些License的注释内容。

把你的JAD文件内容贴出来看看

[haoweishow01]

MIDlet-Jar-Size: 4350
MIDlet-Jar-URL: SnapperMIDlet.jar
MIDlet-Name: SnapperMIDlet
MIDlet-Vendor: Vendor
MIDlet-Version: 1.0
MicroEdition-Configuration: CLDC-1.1
MicroEdition-Profile: MIDP-2.1


帮忙看看。谢谢啊

[houjin_cn]

少了一项下面这样的:
MIDlet-1: SnapperMIDlet, /icon.png, com.xxx.Main

com.xxx.Main改为你的Midlet类名

[houjin_cn]

另外, 不知道E71的参数, 你代码中如果没有用到特殊的API
就
MicroEdition-Configuration: CLDC-1.0
MicroEdition-Profile: MIDP-2.0

[haoweishow01]

试了一下，真的是这个问题啊。加上那个就好了。

奇怪的是，我有另外个project，代码是自己写的，这个的jad里就有MIDlet-1: ****这些东西。

而这个工程我重新清理了再生成，还是没有。请问一下，这个可能是什么原因导致的呢?
谢谢你啦。
