• Netbean6.8: Cant deploy an webapp with Message Driven Bean

  - by Harry Pham

  I create an Enterprise Application CustomerApp that also generated two projects CustomerApp-ejb and CustomerApp-war. In the CustomerApp-ejb, I create a SessionBean call CustomerSessionBean.java as below. package com.customerapp.ejb; import javax.ejb.Stateless; import javax.ejb.LocalBean; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; @Stateless @LocalBean public class CustomerSessionBean { @PersistenceContext(unitName = "CustomerApp-ejbPU") private EntityManager em; public void persist(Object object) { em.persist(object); } } Now I can deploy CustomerApp-war just fine. But as soon as I create a Message Driven Bean, I cant deploy CustomerApp-war anymore. When I create NotificationBean.java (message driven bean), In the project destination option, I click add, and have NotificationQueue for the Destination Name and Destination Type is Queue. Below are the code package com.customerapp.mdb; import javax.ejb.ActivationConfigProperty; import javax.ejb.MessageDriven; import javax.jms.Message; import javax.jms.MessageListener; @MessageDriven(mappedName = "jms/NotificationQueue", activationConfig = { @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"), @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue") }) public class NotificationBean implements MessageListener { public NotificationBean() { } public void onMessage(Message message) { } } If I remove the @MessageDriven annotation, then I can deploy the project. Any idea why and how to fix it?

• Java: Implement own message queue (threadsafe)

  - by derMax

  The task is to implement my own messagequeue that is thread safe. My approach: public class MessageQueue { /** * Number of strings (messages) that can be stored in the queue. */ private int capacity; /** * The queue itself, all incoming messages are stored in here. */ private Vector<String> queue = new Vector<String>(capacity); /** * Constructor, initializes the queue. * * @param capacity The number of messages allowed in the queue. */ public MessageQueue(int capacity) { this.capacity = capacity; } /** * Adds a new message to the queue. If the queue is full, it waits until a message is released. * * @param message */ public synchronized void send(String message) { //TODO check } /** * Receives a new message and removes it from the queue. * * @return */ public synchronized String receive() { //TODO check return "0"; } } If the queue is empty and I call remove(), I want to call wait() so that another thread can use the send() method. Respectively, I have to call notifyAll() after every iteration. Question: Is that possible? I mean does it work that when I say wait() in one method of an object, that I can then execute another method of the same object? And another question: Does that seem to be clever?

• Message queue proxy in Python + Twisted

  - by gasper_k

  Hi, I want to implement a lightweight Message Queue proxy. It's job is to receive messages from a web application (PHP) and send them to the Message Queue server asynchronously. The reason for this proxy is that the MQ isn't always avaliable and is sometimes lagging, or even down, but I want to make sure the messages are delivered, and the web application returns immediately. So, PHP would send the message to the MQ proxy running on the same host. That proxy would save the messages to SQLite for persistence, in case of crashes. At the same time it would send the messages from SQLite to the MQ in batches when the connection is available, and delete them from SQLite. Now, the way I understand, there are these components in this service: message listener (listens to the messages from PHP and writes them to a Incoming Queue) DB flusher (reads messages from the Incoming Queue and saves them to a database; due to SQLite single-threadedness) MQ connection handler (keeps the connection to the MQ server online by reconnecting) message sender (collects messages from SQlite db and sends them to the MQ server, then removes them from db) I was thinking of using Twisted for #1 (TCPServer), but I'm having problem with integrating it with other points, which aren't event-driven. Intuition tells me that each of these points should be running in a separate thread, because all are IO-bound and independent of each other, but I could easily put them in a single thread. Even though, I couldn't find any good and clear (to me) examples on how to implement this worker thread aside of Twisted's main loop. The example I've started with is the chatserver.py, which uses service.Application and internet.TCPServer objects. If I start my own thread prior to creating TCPServer service, it runs a few times, but the it stops and never runs again. I'm not sure, why this is happening, but it's probably because I don't use threads with Twisted correctly. Any suggestions on how to implement a separate worker thread and keep Twisted? Do you have any alternative architectures in mind?

• Erlang message loops

  - by Roger Alsing

  How does message loops in erlang work, are they sync when it comes to processing messages? As far as I understand, the loop will start by "receive"ing a message and then perform something and hit another iteration of the loop. So that has to be sync? right? If multiple clients send messages to the same message loop, then all those messages are queued and performed one after another, or? To process multiple messages in parallell, you would have to spawn multiple message loops in different processes, right? Or did I misunderstand all of it?

• Red 5, First setup "ssl_error_rx_record_too_long" error message

  - by charles horvath

  I am using Windows 7 and I installed Red 5 0.9.1 just recently. After it installed I put 127.0.0.1 as the IP adress and 5080 as http port. After I start the service in windows I try to connect to the localhost in firefox (http://localhost:5080) and get this error An error occurred during a connection to localhost:5080. SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long) I checked my global flash settings and allowed localhost to pass along with the Red 5 folder in C/programfiles/red5. I currently have the up to date versions of JDK and JRE also. Any tips on what might be wrong?

• How do ring and bus network connect to router?

  - by lantopology

  Sorry this is probably a very silly question, but for some reason i am confused. How does a LAN with bus or ring topology connect to a router and other LANs? For example in a star network they all connect to a switch which can then connect to a router, but where does a switch go and fit in a bus or ring topology? In this image of a ring network there is no switch: http://www.brainbell.com/tutorials/Networking/images/01fig04.gif would the switch in the ring network simply be placed alongside the other nodes? Thank you very much

• Bring OS X Error Message window to the front

  - by Debilski

  In OS X, when an application crashes, a window with an error report will appear. That window is by default unreachable by Command+Tab nor does it appear in the Dock. Of course, if by error or on purpose one clicks another window, the error report will go to the background and hide behind the other windows. This is really annoying, because in order to see it, I will have to use Exposé and scan through 20+ Windows in order to find it. (Not to say, that I don’t like Exposé anymore since Snow Leopard made the window sizes all confusingly equal.) Any ideas on how to make the error reports Command+Tabbable?

• NVIDIA error "fallen off the bus"

  - by yurividal

  i have been having a Serious Issue with my LG notebook and its Nvidia Geforce 310M GPU. It usualy (99% of the time) happens when i leave the computer idle for a while, but it has also happened sometimes while i was using the PC. Suddenly, (usualy when computer is idle) the screen goes black, and the pc freezes completely on the black screen. (not even ping responses). The only sollution is to Hard Reset the machine. When analizing the syslog, i see the following error: Sep 18 20:58:08 yuri-notebook kernel: [ 1936.510073] NVRM: GPU at 0000:01:00.0 has fallen off the bus.

The problem does not seem to be hardware, because when i boot into windows 7, it works normaly, for days. I am desperate with this problem, because it makes my Ubuntu practicaly unusable. Thanks in advance, Yuri

• Azure Service Bus - Authorization failure

  - by Michael Stephenson

  I fell into this trap earlier in the week with a mistake I made when configuring a service to send and listen on the azure service bus and I thought it would be worth a little note for future reference as I didnt find anything online about it.  After configuring everything when I ran my code sample I was getting the below error. WebHost failed to process a request.Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/28316044Exception: System.ServiceModel.ServiceActivationException: The service '/-------/BrokeredMessageService.svc' cannot be activated due to an exception during compilation.  The exception message is: Generic: There was an authorization failure.

• Name one good reason for immediately failing on a SMTP 4xx code

  - by Avery Payne

  I'm really curious about this. The question (highlighed in bold): Can someone name ONE GOOD REASON to have their email server permanently set up to auto-fail/immediate-fail on 4xx codes? Because frankly, it sounds like "their" setups are broken out-of-the-box. SMTP is not Instant Messaging. Stop treating it like IRC or Jabber or MSN or insert-IM-technology-here. I don't know what possesses people to have the "IMMEDIATE DELIVERY OR FAIL" mentality with SMTP setups, but they need to stop doing that. It just plain breaks things. Every two or three years, I stumble into this. Someone, somewhere, has decided in their infinite wisdom that 4xx codes are immediate failures, and suddenly its OMGWTFBBQ THE INTARNETZ ARE BORKEN, HALP SKY IS FALLING instead of "oh, it'll re-attempt delivery in about 30 minutes". It amazes me how it suddenly becomes "my" problem that a message won't go through, because someone else misconfigured "their" SMTP service. IF there is a legitimate reason for having your server permanently set up in this manner, then the first good answer will get the check. IF there is no good reason (and I suspect there isn't), then the first good-sounding-if-still-logically-flawed answer will get the check.

• Using a service registry that doesn’t suck part II: Dear registry, do you have to be a message broker?

  - by gsusx

  Continuing our series of posts about service registry patterns that suck, we decided to address one of the most common techniques that Service Oriented (SOA) governance tools use to enforce policies. Scenario Service registries and repositories serve typically as a mechanism for storing service policies that model behaviors such as security, trust, reliable messaging, SLAs, etc. This makes perfect sense given that SOA governance registries were conceived as a mechanism to store and manage the policies...(read more)

• Alfa AWUS036H USB wireless adapter not recognized

  - by GFiasco

  The Alfa AWUS036H USB wireless adapter will not be recognized by my netbook (Ubuntu 14.04, Asus X201E). As I understand it, the drivers should already be built in to this version of Linux, but I tried a make/make install of the latest Realtek drivers (as mentioned on How do I install drivers for the Alfa AWUS036H USB wireless adapter?) and it didn't work. I then followed the advice of this thread (ALFA AWUS036NH driver) and did a make/make install of the most up-to-date backport of the drivers, but that didn't work. At this point I tried a series of commands from this thread (http://ubuntuforums.org/showthread.php?t=2187780) in an attempt to identify the problem, but at no point could I get the laptop to ever recognize the USB adapter. I have also troubleshot the USB cable itself, tried both the USB 2.0 and 3.0 ports on the laptop, have never received an error message regarding a need to update the firmware, and have seemingly successfully installed all manner of variation of Realtek drivers which were supposed to make the adapter work. (I also tried to delete/clean up after each install, in the hope I wasn't making things worse.) Not sure what I should do next. Please let me know if I need to post any more information. Thanks very much for your help. EDIT: Before inserting Alpha USB adapter: :~$ lsusb Bus 002 Device 002: ID 8087:0024 Intel Corp.

• Service Bus random thought for the day

  - by Michael Stephenson

  Its been really nice to see that over the last few weeks since we implemented our Dynamics CRM connecting via Azure Service Bus to backend line of business applications solution how much interest this has sparked within the rest of the organisation and other subsiduaries and how many people are coming up with ideas elsewhere on how they can leverage what we did and how simple it could be to connect their applications to the cloud. Im currently working with one of these companies and its refreshing to see how much interest can be spread by a good success story.

• Get close window message in Hidden C# Console Application

  - by LexRema

  Hello everyone. I have a Windows Form that starts some console application in background(CreateNoWindow = rue,WindowStyle = ProcessWindowStyle.Hidden). Windows form gives me opportunity to stop the console application at any time. But I'd like to handle somehow the close message inside the console application. I tried to use hooking like: [DllImport("Kernel32")] public static extern bool SetConsoleCtrlHandler(HandlerRoutine handler, bool add); // A delegate type to be used as the handler routine // for SetConsoleCtrlHandler. public delegate bool HandlerRoutine(CtrlTypes ctrlType); // An enumerated type for the control messages // sent to the handler routine. public enum CtrlTypes { CTRL_C_EVENT = 0, CTRL_BREAK_EVENT, CTRL_CLOSE_EVENT, CTRL_LOGOFF_EVENT = 5, CTRL_SHUTDOWN_EVENT } private static bool ConsoleCtrlCheck(CtrlTypes ctrlType) { StaticLogger.Instance.DebugFormat("Main: ConsoleCtrlCheck: Got event {0}.", ctrlType); if (ctrlType == CtrlTypes.CTRL_CLOSE_EVENT) { // Handle close stuff } return true; } static int Main(string[] args) { // Subscribing HandlerRoutine hr = new HandlerRoutine(ConsoleCtrlCheck); SetConsoleCtrlHandler(hr, true); // Doing stuff } but I get the message inside ConsoleCtrlCheck only if the console window is created. But if window is hidden - I don't get any message. In my windows Form to close console application process I use proc.CloseMainWindow(); to send message to the console window. P.S. AppDomain.CurrentDomain.ProcessExit += CurrentDomain_ProcessExit; - also does not help Do you now other way to handle this situation? Thanks.

• Thread Message Loop Hangs in Delphi

  - by erikjw

  Hello all. I have a simple Delphi program that I'm working on, in which I am attempting to use threading to separate the functionality of the program from its GUI, and to keep the GUI responsive during more lengthy tasks, etc. Basically, I have a 'controller' TThread, and a 'view' TForm. The view knows the controller's handle, which it uses to send the controller messages via PostThreadMessage. I have had no problem in the past using this sort of model for forms which are not the main form, but for some reason, when I attempt to use this model for the main form, the message loop of the thread just quits. Here is my code for the threads message loop: procedure TController.Execute; var Msg : TMsg; begin while not Terminated do begin if (Integer(GetMessage(Msg, hwnd(0), 0, 0)) = -1) then begin Synchronize(Terminate); end; TranslateMessage(Msg); DispatchMessage(Msg); case Msg.message of // ...call different methods based on message end; end; To set up the controller, I do this: Controller := TController.Create(true); // Create suspended Controller.FreeOnTerminate := True; Controller.Resume; For processing the main form's messages, I have tried using both Application.Run and the following loop (immediately after Controller.Resume) while not Application.Terminated do begin Application.ProcessMessages; end; I've run stuck here - any help would be greatly appreciated.

• Jquery/Javascript gmail style stuff for message inbox, such as select all message using checkbox etc

  - by Psychonetics

  I am enjoying the fact that I'm here building a private message inbox for my website after building a full user signup/login and activation system when a few months ago I thought I wouldn't have enough patience to learn this stuff. Anyway to my question. I am currently building the private message inbox for my users and wondering if there are any jquery/javascript stuff I can use to make my inbox more like the gmail inbox. E.G. Gmail allows you to select all read messages or unread or starred or unstarred or none of the messages using a checkbox. I would like to add this kind of feature to my website and I'm sure the easiest way to achieve this would be using a jquery/javascript script. I would appreciate if someone could provide some links or info to where I can find several of these types of scripts to use with my inbox page. Thanks EDIT: Would also like to note that I would like the checkbox to be in a dropdown just like gmails.

• Amazon SQS invalid binary character in message body

  - by letronje

  I have a web app that sends messages to an Amazon SQS Queue. Amazon sqs lib throws a 'AmazonSQSException' since the message contained invalid binary character. The message is the referrer obtained from an incoming http request. This is what it looks like: http://ads.vrx.adbrite.com/adserver/display_iab_ads.php?sid=1220459&title_color=0000FF&text_color=000000&background_color=FFFFFF&border_color=CCCCCC&url_color=008000&newwin=0&zs=3330305f323530&width=300&height=250&url=http%3A%2F%2Funblockorkutproxy.com%2Fsearch.php%2FOi8vZG93%2FbmxvYWRz%2FLnppZGR1%2FLmNvbS9k%2Fb3dubG9h%2FZGZpbGUv%2FNTY5MTQ3%2FNi9NeUN1%2FdGVHaXJs%2FZnJpZW5k%2FWmFoaXJh%2FLndtdi5o%2FdG1s%2Fb0%2F^Fô}úÃ<99ë)j Looks like the characters in bold are the invalid characters. Is there an easy way to filter out characters characters that are not accepted by amazon ? Here are the characters allowed by amazon in message body. I am not sure what regex i should use to replace invalid characters by ''

• Displaying custom error message for a blank field in a simple JSF application

  - by 29b5k

  Hi all, I was trying out a simple JSF application, in which I need to check if the "name" field is blank, then display an error message. The code which takes the field's value is: <h:outputLabel value="Name"></h:outputLabel> <h:inputText value="#{greeting.name}" required = "true"> <f:validator validatorId="NumValidator"></f:validator> </h:inputText> The control of the program does not go into the validator class, if the field is submitted without entering anything, and it displays the default error message: j_id_jsp_869892673_1:j_id_jsp_869892673_4: Validation Error: Value is required. How do i display a custom message for this ?

• Passing message over network

  - by Sylvestre Equy

  Hi, I'm currently trying to develop a message-oriented networking framework and I'm a bit stuck on the internal mechanism. Here are the problematic interfaces : public interface IMessage { } public class Connection { public void Subscribe<TMessage>(Action<TMessage> messageCallback); public void Send<TMessage>(TMessage message); } The Send method does not seem complicated, though the mechanism behind Subscribe seems a bit more painful. Obviously when receiving a message on one end of the connection, I'll have to invoke the appropriate delegate. Do you have any advice on how to read messages and easily detect their types ? By the way, I'd like to avoid to use MSMQ.
