<p>Message filtering does not work - fail to understand what is wrong with the code.This doesn't retrieve any msgs at all. Howevver if I use ("".getBytes()), it works fine and returns all msgs published. I'm using JZMQ2.1.3.jar. Please suggest. Thanks!!</p> <pre><code>public class OMQSubFilter { public static void main (String[] args) { // Prepare our context and subscriber Context context = ZMQ.context(1); Socket subscriber = context.socket(ZMQ.SUB); // System.out.print("Subscriber started"); subscriber.connect("tcp://localhost:5556"); // Subscribe to keywords, default is All String twtFilter = (args.length > 0) ? args[0] : ""; subscriber.subscribe(twtFilter.trim().getBytes()); System.out.print("Filter: "+ twtFilter.trim()); while (!Thread.currentThread ().isInterrupted ()) { byte[] tweet = subscriber.recv(0); String str = new String(tweet); //String str = subscriber.recvStr(0).trim(); System.out.print(str); } subscriber.close (); context.term (); } } </code></pre> <p>And here is the publisher code:</p> <pre><code>public class OMQPub { public static void main (String[] args) { Context zcontext = ZMQ.context(1); Socket pub = zcontext.socket(ZMQ.PUB); pub.bind("tcp://*:5556"); java.util.List<TweetStatus> tweets = ct.getTweets(); Iterator<TweetStatus> iter = tweets.iterator(); String tweetStr = ""; try { Thread.sleep (1000); } catch (InterruptedException e) { e.printStackTrace(); } while (iter.hasNext()) { TweetStatus tweet = iter.next(); tweetStr = Utility.jsonFormat(tweet, ct.getKeywords()); System.out.println(" TweetStr : "+tweetStr); pub.send(tweetStr.getBytes(), ZMQ.NOBLOCK); } //pub.close(); //zcontext.term(); //zcontext.term() hangs even all the sockets created in the context are closed. } } </code></pre>

Guidance

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.
