    <p>My goal is to play an mp3 file from Java. With every approach that I took, it always fails with a <code>LineUnavailableException</code>.</p> <pre><code> AudioInputStream inputStream = AudioSystem.getAudioInputStream(new URL("http://localhost:8080/agriserver/facebook/sound/test6.mp3")); Clip clip = AudioSystem.getClip(info); clip.open(inputStream); clip.start(); </code></pre> <p>Failed attempts to fix it:</p> <ul> <li>Use Sun's mp3 plugin.</li> <li>Use Jlayer 3rd party library</li> <li>Use Tritonus 3rd party library</li> <li>Re-encode the mp3 with Sony Sound Forge, Adobe Sound Booth, all no luck</li> <li>Re-encode the mp3 with different encode rates and sampling rates</li> <li>Try to use JMF</li> <li>Use random mp3 from the Internet that plays fine in other applications</li> <li>Read postings with the same error. None of the postings have an answer that helped resolve the issue.</li> </ul> <p>Here is the exception:</p> <pre> Exception in thread "main" javax.sound.sampled.LineUnavailableException: line with format MPEG1L3 48000.0 Hz, unknown bits per sample, stereo, unknown frame size, 41.666668 frames/second, not supported. at com.sun.media.sound.DirectAudioDevice$DirectDL.implOpen(DirectAudioDevice.java:494) at com.sun.media.sound.DirectAudioDevice$DirectClip.implOpen(DirectAudioDevice.java:1280) at com.sun.media.sound.AbstractDataLine.open(AbstractDataLine.java:107) at com.sun.media.sound.DirectAudioDevice$DirectClip.open(DirectAudioDevice.java:1061) at com.sun.media.sound.DirectAudioDevice$DirectClip.open(DirectAudioDevice.java:1151) at Demo.playMp3(Demo.java:83) </pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
