jar中运行结果与jbulider中运行结果不一至,急,帮忙解决

[wudidaoshi]

程序运行都没问题,包也调用正确,但是执行到 device = CaptureDeviceManager.getDevice(str2);
就出错了
str2 的值是 str2 = "vfw:Microsoft WDM Image Capture (Win32):0";
驱动也没写错,怎么不能在jar中运行啊,好郁闷...谁知道帮我解决一下， 谢谢了

CaptureDeviceManager.getDevice
把错误贴出来
最好把getDevice这个方法也贴出来

{ device = CaptureDeviceManager.getDevice(str2); //得到设备
locator = device.getLocator();
try {
player = Manager.createRealizedPlayer(locator);
player.start();
} catch (Exception e) {
}


}
}

其实应该是正确的代码,在jbluider中还可以运行的,在打包成jar后,运行还是可以,就是打不开摄像头

JMF库 引用问题？

[wudidaoshi]

我也觉得是,但是引用也没问题.不知道何解...

郁闷ing...

你自己写一个bat文件，来运行试试，bat文件就不用我教你写了吧！
以上代码我试了，在Eclipse下确实在加载驱动的时候报错，但是直接用BOS命令行来运行是可以的，
如果你用的是JDK6.0，那么会有几个警告，如果是JDK5.0，那么什么警告也没有
