copied!<p><strong>1 : This might not be a bug !</strong></p> <p>[assuming that there is readable data in the buffer]...</p> <p>You would expect a -1 at the end of the stream... See <a href="http://docs.oracle.com/javase/1.4.2/docs/api/java/nio/channels/SocketChannel.html#read%28java.nio.ByteBuffer%29" rel="nofollow">http://docs.oracle.com/javase/1.4.2/docs/api/java/nio/channels/SocketChannel.html#read%28java.nio.ByteBuffer%29</a> </p> <p>If you are continually recieving a positive value from the read() call, then you will need to determine why data is being read continually. </p> <p>Of course, the mystery herein ultimately lies in the source data (i.e. the SocketChannel which you are read data from).</p> <p><strong>2: Explanation of your possible problems</strong></p> <p>If your socket channel is coming from a REAL file, which is finite then your file is really big, and eventually, the read() operation will return 0... eventually...</p> <p>If, on the other hand, your socket channel is listening to a source of data which you EXPECT to be finite (i.e. a serialized object stream, for example), I would double check the source --- maybe your finite stream is simply producing more and more data... and you are correctly consuming it. </p> <p><strong>3: Finally some advice</strong></p> <p>A trick for debugging this type of error is playing with the ByteBuffer input to your read method : the nice thing about java.nio's ByteBuffers is that, since they are more object oriented then the older byte[] writers, you can get very fine-grained debugging of their operations. </p>
