  • overwrite blackberry's send sms/mail method

    - by Luis Armando
    I haven't been able to found this on Google, so I thought maybe somene here knew if this was possible and if so, how to implement it =) thanks in advance for any answers! What I am aiming for is overwriting this method so I can perform some actions before the sms/mail gets sent, then just allow it to perform its normal actions.

  • Jface's CheckboxTreeViewer how to set initial selection

    - by Hypercube
    Hello. This question may sounds trivial, but i am struggling with the issue, so, please help if u can. So, here it is : i am using a CheckboxTreeViewer for some good reasons. I've google-it for some class usages, and i am currently able to check/uncheck all the childrens of a selected node, and to preserve the selection after a live search with a custom implementation of the StyledCellLabelProvider provider. All good so far. However, so far i am unable to programatically select one or more elements of the tree viewer after i display the widget and call the setInput() method of the viewer. So, let's assume for instance that the tree will have 10 main nodes, and 5 leafs on node 6. My question is how do i set the checked state of the 3rd leaf? Thank u.

  • Does JAXWS client make difference between an empty collection and a null collection value as returne

    - by snowflake
    Since JAX-WS rely on JAXB, and since I observed the code that unpack the XML bean in JAX-B Reference Implementation, I guess the difference is not made and that a JAXWS client always return an empty collection, even the webservice result was a null element: public T startPacking(BeanT bean, Accessor<BeanT, T> acc) throws AccessorException { T collection = acc.get(bean); if(collection==null) { collection = ClassFactory.create(implClass); if(!acc.isAdapted()) acc.set(bean,collection); } collection.clear(); return collection; } I agree that for best interoperability service contracts should be non ambiguous and avoid such differences, but it seems that the JAX-WS service I'm invoking (hosted on a Jboss server with Jbossws implementation) is returning as expected either null either empty collection (tested with SoapUI). I used for my test code generated by wsimport. Return element is defined as: @XmlElement(name = "return", nillable = true) protected List<String> _return; I even tested to change the Response class getReturn method from : public List<String> getReturn() { if (_return == null) { _return = new ArrayList<String>(); } return this._return; } to public List<String> getReturn() { return this._return; } but without success. Any helpful information/comment regarding this problem is welcome !

  • JAXB - representing element as boolean?

    - by Marcus
    We have this XML: <Summary> <ValueA>xxx</ValueA> <ValueB/> </Summary> <ValueB/> will never have any attributes or inner elements. It's a boolean type element - it exists (true) or it doesn't (false). JAXB generated a Summary class with a String valueA member, which is good. But for ValueB, JAXB generated a ValueB inner class and a corresponding member: @XmlElement(name = "ValueB") protected Summary.ValueB valueB; But what I'd like is a boolean member and no inner class: @XmlElement(name = "ValueB") protected boolean valueB; How can you do this? I'm not looking to regenerate the classes, I'd like to just make the code change manually.

  • Can I use XText for a DSL involving an XML file type?

    - by Chris
    I have defined a small DSL that is mostly written in the form of different types of XML files in conjuction with some property files. This works very well but I wish to create an Eclipse Editor to make editing these files easier for beginners (I already have a working parser). The main XML file can reference some items from the .properties files and vice-versa. THe main xml file can also reference other XML files. Certain options should only be available in the main xml file based on the contents of the .properties files and based on some osgi plugins that can be added to the DSL project (the syntax is dynamic depending on context). The structure of the language is fixed but the options available in each attribute or the choice of attributes themselves changes depending on metadata contained in plugin .jar files. Questions: Does XText support dynamic syntax (validation changes depending on external factors)? Does XText support XML files / .properties files? Thank you very much for your help in advance.

  • IVR-style dialog system / workflow / menu

    - by unbeli
    I need to build a dialog system similar to IVR used in call centers. My system is not phone-based, but the dialog is similar. Something like System: "Main menu: Enter [1] for menu1, [2] for menu2" User: [1] System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [7] System: "What??" System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [2] ... and so on I want to have a nice declarative description of all the possible options and a nice way to run through that tree, guided by user input. Already considered: ANTLR-generated lexer/parser (seems to be an overkill), SCXML-based state machine (seems like only transitions can be declared, the rest needs to be coded)

  • Unable to connect on socket across different networks.

    - by maleki
    I am having trouble connecting my online application to others across another network. I am able to give them the hostAddress to connect when we are on the same network but when we are doing it across the internet the generated host address doesn't allow a connection, nor does using the ip address gotten from online sites such as whatismyip.com My biggest issue isn't debugging this code, because it works over intra-network but The server doesn't see attempts when we try to move to different networks. Also, the test ip I am using is 2222. InetAddress addr = InetAddress.getLocalHost(); String hostname = addr.getHostName(); System.out.println("Hostname: " + hostname); System.out.println("IP: " + addr.getHostAddress()); I display the host to the server when it is starting if (isClient) { System.out.println("Client Starting.."); clientSocket = new Socket(host, port_number); } else { System.out.println("Server Starting.."); echoServer = new ServerSocket(port_number); clientSocket = echoServer.accept(); System.out.println("Warning, Incoming Game.."); }

  • One entityManger finds entity , the other does not.

    - by Pitelk
    Hi all, I have a very strange behavior in my program. I have 2 classes (class LogIn and CreateGame) where i have injected an EntityManager in each using the annotation @PersistenceContext(unitName="myUnitPU") EntityManager entitymanger; In some point i remove an object called "user" from the database using entitymanger.remove(user) from a method in LogIn class. The business logic is that a user can host and join games ( in the same time) so removing the user all the entries in database about the games the user has created are removed and all the entries showing in which games the user has joined are removed also. After that, i call another function which checks if the user exists using a method in the LogIn class entitymanager.find(user) which surprisingly enough, finds the user. After that I call a method in CreateGame class which tries to find the user by using again entitymanger.find(user) the entitymanger in that class fails to find the user (which is the expected result as the user is removed and it's not in the database) So the question is : Why the entitymanager in one class finds the user (which is wrong) where the other doesn't find it? Does anyone has ever the same problem? PS : This "bug" occurs when the user has hosted a game which is joined by another user (lets call him Buser) and the Buser has made a game which is joined by the current user. GAME | HOST | CLIENTS game1 | user | userB game2 | userB | user where in this case by removing the user, the game1 is deleted and the user is removed from game2 so the result is GAME | HOST | CLIENTS game2 | userB | PS2 : The Beans are EJB3.0. The methods are called from a delegate class. The beans in the delegate class are instantiated using the InitialContext.lookup() method. Note that for logging in ,creating , joining games the appropriate delegate class calls the correspondent EJB which does the transactions. In the case of logOut, the delegate calls an EJB to logout the user but becuase other stuff must be done (as said above) this EJB calls other EJB (again using lookup() ) which has methods like removegame(), removeUserFromGame() etc. After those methods are executed the user is then logged out. Maybe it has something to do with the fact the the first entity manager is called by a delegate but the second from inside an EJb and thats why the one entitymanger can see the non-existent user while the other cannot? Also all the methods have TRANSACTIONTYPE.REQUIRED Thank you in advance

  • How to pass get-parameter to backing bean in jsf?

    - by Roman
    I have get parameter with name controller. When I try to pass it (with propertyChangeListener) to my backing bean I get null instead of the real value of the parameter: <h:commandButton value="#{msg['mail.send']}" styleClass="mailbutton" action="#{mailSender.sendMail}"> <f:setPropertyActionListener target="#{mailSender.controllerName}" value="{#param.controller}"/> </h:commandButton> So, I have two questions: What is the proper way to set bean property with a get-parameter value? Actually, I've already get the value from ExternalContext#getRequestParam but maybe there are some other solutions. More interesting question: why propertyActionListener didn't work here? What does it do actually? (again I have some thoughts about it but it would be nice to read more comprehensive explanations).

  • Google datastore stats

    - by Keyur
    I am querying the __Stat_Kind__ kind. It does not return me entities about kinds that currently exist in the datastore but it includes entities about kinds that I had deleted more than a week ago. I am not so much concerned about it returning me the non-existent kinds - the doc does mention this scenario after all. But I am concerned that it does not return me info about my current kinds. Is this a known issue or am I doing something wrong? To folks on the app engine team: Also, on the dev server neither __Stat_Kind__ nor __Stat_Total__ return any entities. Which means I need to deploy my app to appspot before I can test this behavior. It would be nice if the dev server did return some basic info. Thanks, Keyur

  • Implementing a Stack using Test-Driven Development

    - by devoured elysium
    I am doing my first steps with TDD. The problem is (as probably with everyone starting with TDD), I never know very well what kind of unit tests to do when I start working in my projects. Let's assume I want to write a Stack class with the following methods(I choose it as it's an easy example): Stack<T> - Push(element : T) - Pop() : T - Seek() : T - Count : int - IsEmpty : boolean How would you approch this? I never understood if the idea is to test a few corner cases for each method of the Stack class or start by doing a few "use cases" with the class, like adding 10 elements and removing them. What is the idea? To make code that uses the Stack as close as possible to what I'll use in my real code? Or just make simple "add one element" unit tests where I test if IsEmpty and Count were changed by adding that element? How am I supposed to start with this?

  • Remove JButton padding in MigLayout

    I have a small "popup" like this: But I don't want the padding around the button, I want it to be as small as it can be with the supplied text. btn.setMargin(new Insets(1, 1, 1, 1)); panel.add(lbl, "wrap"); panel.add(btn); frame.pack(); frame.setVisible(true); At least this doesn't work... Can this be achieved on MigLayout or should I use some other layout manager for this frame.

  • Just curious, in NetBeans IDE 6.1 how can i get icons for my custom GUI components in the GUI editor

    - by Coder
    This is by no means really important, i was just wondering if the community knows how to put icons for my custom GUI components that show up in the NetBeans GUI designer. What i did was make several Swing components and then i use the menu options to add them to the GUI pallete, but they show up with "?" icons. It would be nice if they showed up with icons similar to swing components such as JButtons, especially for components which are subclassed for Swing components. Thanks!

    hi! i hav a panel and i m trying to remove labels from it which were added to it during run-time. but when labels are removed succesfully i m not able to use the space,left by that label,again to add any label to it. thanks in anticipation of the solution. here is the relevant code snippet: to add label to the panel: JLabel jl = new JLabel(); jl.setOpaque(true); jl.setIcon(new ImageIcon("D:/Project/router2.jpg")); jl.setBounds(x, y,jl.getPreferredSize().width,jl.getPreferredSize().height); for(Component c :lcomponent) { flag=true; Rectangle r4=c.getBounds(); int x1=(int) r4.getX(); int y1=(int) r4.getY(); Rectangle r5 = new Rectangle(new Point(x1-60, y1-60),new Dimension(170,170)); if(r5.contains(p)){ //To ensure that two labels do not overlap or are too close flag = false; // to each other break; }} if(flag) { p2.add(jl); //p2 is a panel Component c2 = p2.getComponentAt(x,y); p2.repaint(); lcomponent.add(c2); //lcomponent is an ArrayList<Component> to store all the labels added to the panel } 2.to remove the label: p2.remove(); p2.repaint();

  • JLabel with separate text and icon background colours

    - by emeraldjava
    Hey, I have a simple Jlabel element with text and icon setting the background changes the full label colour. I want to be able to only render the background colour on the text section of the label, ie - to have separate backgrounds/foregrounds for the icon and text. Selecting/deselecting the label will flip the colour behind the icon and text. Is this possible to do this by just extending JLabel, and if so which methods should i be looking to customise? My alternative idea is to create a panel with two separate label elements, one with an icon the other with text. It seems a bit messy, and before i start i'm wondering is there a smarter way of achieving this with Swing.

  • Question about spring manning-in-action

    - by Gandalf StormCrow
    I saw people asking about best book for learning spring, and I came across manning.spring in action was recommended most of the time so I decided to give it a go. The thing is the author offers some pretty reasonable explanations, puzzle by puzzle it gets in your head, than you just need to code it and you're done, you get it(this is how I work don't know about the others). When it comes to the code its very disapointing, I went trought the Knight example like 2 or 3 times by now and I see its incorrect in the book, I mean its hard already for people eager to learn and why not a note somewhere in the book like pseudo-code or something. The knight example in the first chapter is missing two classes QuestFailedException and HolyGrail I mean other people must have noticed this, why is everyone recommending this book without saying at least it has some errors(like many others do), was anyone actually been able to compile and this first chapter example?
