    <p>Dear Stack Overflow Geeks,</p> <p>I'm trying to create a very basic Java client-server app using Java EE 7 and the intention is to send a message via websocket using JSR 356 implementation.</p> <p>I've programmed and deployed the server successfully following various blogs I've found out there and I was able to communicate a Javascript client with my java server.</p> <p>Now what I'm trying to do is to create an standalone java app that needs to communicate with the server and retrieve the same info. I read that JSR 356 implementation can be used in Java clients and that's exactly what I did. I also used Tyrus to create the client and keep it running using the latch mechanism, etc etc etc. Beautiful. The client is finally programmed, the server is up and running BUT when I try to run the client I get this error:</p> <pre class="lang-none prettyprint-override"><code>java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.glassfish.appclient.client.acc.AppClientContainer.launch(AppClientContainer.java:446) at org.glassfish.appclient.client.AppClientFacade.main(AppClientFacade.java:166) Caused by: java.lang.NoClassDefFoundError: javax/websocket/CloseReason$CloseCode at Main.Main.main(Main.java:27) ... 6 more Caused by: java.lang.ClassNotFoundException: javax.websocket.CloseReason$CloseCode at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at org.glassfish.appclient.client.acc.ACCClassLoader.findClass(ACCClassLoader.java:237) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) ... 7 more Java Result: 1 </code></pre> <p>I'm using Java EE 7 API + Tyrus in NetBeans 7.3 and deploying in a Glassfish 4 (which, from what I've read supports JSR 356 implementation) Now, why on earth is not finding the CloseReason class! :( It should not have compiled if that's the case, isn't it?</p> <p>Weird thing is that is not complaining about other classes related to websocket implementation (JSR 356) and, on the other hand, I deployed the server (web-app) and the websocket mechanism is working just fine. (I think I didn't implement the CloseReason there though.. but why it's complaining only about that! :@ )</p> <p>Any help provided will be much appreciated!!</p> <p>Cheers,</p> <p>Another Stack Overflow Geek seeking for help. :)</p>

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.
