Please help me in this matter as soon as possible.I am a beginner so a possible coding would be appreciated.
我目前正在使用 netbeans 并且我已经使用它自己的插件查找器下载了 JMF 插件。我从网上找到了使用 JMF 进行视频流传输的代码之一。“导入 javax.media.player”显示包 javax的错误.media 不存在。请尽快帮助我解决这个问题。我是初学者，因此可能的编码将不胜感激。

import javax.media.NoPlayerException;
import javax.media.Player;

import javax.management.*;
public class MediaPlayer extends JPanel {
public MediaPlayer() {
setLayout( new BorderLayout() ); // use a BorderLayout
// Use lightweight components for Swing compatibility
Manager.setHint( Manager.LIGHTWEIGHT_RENDERER, true );
try
{
// create a player to play the media specified in the URL
Player mediaPlayer = Manager.createRealizedPlayer("E:\FFOutput\Bollywood");
// get the components for the video and the playback controls
Component video = mediaPlayer.getVisualComponent();
Component controls = mediaPlayer.getControlPanelComponent();
if ( video != null )
add( video, BorderLayout.CENTER ); // add video component
if ( controls != null )
add( controls, BorderLayout.SOUTH ); // add controls
mediaPlayer.start(); // start playing the media clip
} // end try
catch ( NoPlayerException noPlayerException )

System.err.println( "No media player found" );

In OSX, you can set the classpath from scratch like this:
在 OSX 中，您可以像这样从头开始设置类路径：
export CLASSPATH=/path/to/some.jar:/path/to/some/other.jar
Or you can add to the existing classpath like this:
或者您可以像这样添加到现有的类路径中：
export CLASSPATH=$CLASSPATH:/path/to/some.jar:/path/to/some/other.jar
