  • Converting JBOSS annotations to xml

    - by sixtyfootersdude
    Good Morning, I was just hoping that someone could point me to a reference that defines about what JBOSS annotations are equivalent to what xml tags. I am particularly interested in these tags: @WebContext in org.jboss.ws.annotation.WebContext and @SecurityDomain in org.jboss.annotation.security.SecurityDomain

  • How can I retrieve the value of a PASTE (copy-pasta) event in a GWT TextBox?

    - by dominicbri7
    Hello fellow SO members, I want to prevent the user from copy-pasting values in my TextBox IF AND ONLY IF the values do not respect a certain condition. For instance, I created a DigitsOnlyTextBox which will be used for phone numbers. I already made it so only Character.isDigit characters can be typed into the box, and the user cannot copy-paste values into it, using : this.sinkEvents(Event.ONPASTE); and public void onBrowserEvent(Event event) { super.onBrowserEvent(event); // Permet d'empêcher le copier-coller, donc d'entrer des caractères non-numériques if (event.getTypeInt() == Event.ONPASTE) { event.stopPropagation(); event.preventDefault(); } } But I'd like to verify if the copy-pasted String is "digits only" and if so, let the event happen (therefore the text added). tl;dr : see title Thank you for your time. Sincerely.

  • Type-safe mapping from Class<T> to Thing<T>

    - by Joonas Pulakka
    I want to make a map-kind of container that has the following interface: public <T> Thing<T> get(Class<T> clazz); public <T> void put(Class<T> clazz, Thing<T> thing); The interesting point is that the Ts in each Class<T><- Thing<T> pair is the same T, but the container should be able to hold many different types of pairs. Initially I tried a (Hash)Map. But, for instance, Map<Class<T>, Thing<T>> is not right, because then T would be same T for all pairs in that map. Of course, Map<Class<?>, Thing<?>> works, but then I don't have type-safety guarantees so that when I get(String.class), I can't be sure that I get a Thing<String> instance back. Is there a way to accomplish the kind of type safety that I'm looking for?

  • Setting jvmargs in log4j.properties file

    - by Thomas
    Hey This is a bit of a weird request but I am trying to set some jvmargs in the log4j.properties file. At present I use ant to for example set some args.... jvmarg value="-Dmail.smtp.socketFactory.port=465" ... but it would be great to group a few of these logging relevant arguments into the .properties file. Does anyone know how to do this? Thanks in advance!

  • JButton Image Ignoring GridBagConstraints

    - by daemor
    I am working on an application and have a screen that needs to have elements (namely some custom JButtons) appear and disappear based on a user selection. However for some reason, when I add these buttons to their pane, the buttton image goes to the top corner, and leaves the text in the center, completely ignoring GridBagConstraints. I am completely stumped on this one as I have done this same exact thing dozens of times earlier in the program without any issues. Here is an image of the problem: The problem is in this method here, and occurs down towards the bottom. public void init(){ contentPane.removeAll(); // Setup jlabels JLabel countyLabel = new JLabel("County"); countyLabel.setFont(new Font("Times New Roman", Font.PLAIN, 18)); JLabel measureByLabel = new JLabel("Measure By: "); measureByLabel.setFont(new Font("Times New Roman", Font.PLAIN, 18)); String[] countyChoices = {"Washtenaw", "Oakland", "Livingston"}; // setup components JComboBox<String> countyCombo = new JComboBox<String>(countyChoices); // place baseComponents c.weightx = 0.5; c.weighty = 0.5; c.gridx = 0; c.gridy = 0; c.anchor = GridBagConstraints.NORTH; contentPane.add(countyLabel, c); c.gridx = 2; contentPane.add(countyCombo, c); c.gridy = 1; c.gridx = 0; contentPane.add(trenchButton, c); c.gridx = 2; contentPane.add(bedButton, c); c.gridy = 2; c.gridx = 1; contentPane.add(systemSelection, c); c.gridy = 3; c.gridx = 0; contentPane.add(lengthButton, c); c.fill = GridBagConstraints.BOTH; c.gridwidth = 4; c.gridy = 4; c.gridx = 0; contentPane.add(choicePane, c); GridBagConstraints con = new GridBagConstraints(); con.weightx = 0.5; con.weighty = 0.5; con.gridx = 0; con.gridy = 0; choicePane.add(lengthButton, c); // revalidate and repaint choicePane.revalidate(); choicePane.repaint(); contentPane.revalidate(); contentPane.repaint(); } I have tried doing this in separate methods, the button looks fine when added to the contentPane, the pane is for sure set to gridbagconstraints as I used the expression JPanel choicePane = new JPanel(new GridBagLayout()) to initialize it.

  • Download dynamic file with GWT

    - by Maksim
    I have a GWT page where user enter data (start date, end date, etc.), then this data goes to the server via RPC call. On the server I want to generate Excel report with POI and let user save that file on their local machine. This is my test code to stream file back to the client but for some reason I think it does not know how to stream file to the client when I'm using RPC: public class ReportsServiceImpl extends RemoteServiceServlet implements ReportsService { public String myMethod(String s) { File f = new File("/excelTestFile.xls"); String filename = f.getName(); int length = 0; try { HttpServletResponse resp = getThreadLocalResponse(); ServletOutputStream op = resp.getOutputStream(); ServletContext context = getServletConfig().getServletContext(); resp.setContentType("application/octet-stream"); resp.setContentLength((int) f.length()); resp.setHeader("Content-Disposition", "attachment; filename*=\"utf-8''" + filename + ""); byte[] bbuf = new byte[1024]; DataInputStream in = new DataInputStream(new FileInputStream(f)); while ((in != null) && ((length = in.read(bbuf)) != -1)) { op.write(bbuf, 0, length); } in.close(); op.flush(); op.close(); } catch (Exception ex) { ex.printStackTrace(); } return "Server says: " + filename; } } I've red somewhere on internet that you can't do file stream with RPC and I have to use Servlet for that. Is there any example of how to use Servlet and how to call that servlet from ReportsServiceImpl. Do I really need to make a servlet or it is possible to stream it back with my RPC?

  • Is there any danger in committing to a component library such as SmartGwt or Swing?

    - by Banang
    Since February this year I have been working on an app that's built using SmartGWT components. Generally, I find the components very nice to work with, and the fact that they're open source and free to use is just fantastic. However, I can't seem to shake the feeling that it's not a durable way of developing, but I can't quite explain why. Maybe it's because I know that any minute now the team developing it could decide to stop, which would leave me and my team in a bit of a pickle, but I'm sure there must be something more. I have been trying to find ways of explaining this feeling to myself, but to no avail. Therefore I turn to you, dear community, to ask if you can come up with a good reason why committing to building your app (that's supposed to be around for many more years to come) using a component library such as SmartGWT is a bad idea? Is there any reason I should just have developed the components myself? Or did I make the right choice when deciding not to reinvent the wheel and just go for what was readily available?

  • Auto generation of Web Service sample, help and documentation

    - by orjan
    We're using javax.jws.WebServices deployed in a Glassfish server, is there a way to auto generate documentation like the one ASMX services generates? ASMX services display methods in service ASMX services when running locally could be easily tested with a prebuilt form ASMX services provided a sample request and response XML message http://keithelder.net/blog/archive/2008/01/15/How-to-Get-Around-WCFs-Lack-of-a-Preview-Web.aspx In Glasshfish together with /test/TestApi?wsdl there's /test/TestApi?Tester but it doesn't work, I don't know if it can be used to provide similar features as above?

  • Parsing XML wont display all items.

    I have this code but the toast wont display any message what is wrong with my code.. I can get the value from link, linknext but title wont bring out any value.

  • [hibernate - jpa] @OneToOne annotoation problem (i think...)

    - by blow
    Hi all, im new in hibernate and JPA and i have some problems with annotations. My target is to create this table in db (PERSON_TABLE with personal-details) ID ADDRESS NAME SURNAME MUNICIPALITY_ID First of all, i have a MUNICIPALITY table in db containing all municipality of my country. I mapped this table in this ENTITY: @Entity public class Municipality implements Serializable { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id; private String country; private String province; private String name; @Column(name="cod_catasto") private String codCatastale; private String cap; public Municipality() { } ... Then i make an EMBEDDABLE class Address containing fields that realize a simple address... @Embeddable public class Address implements Serializable { @OneToOne(cascade=CascadeType.ALL) @JoinColumn(name="id_municipality") private Municipality municipality; @Column(length=45) private String address; public Address() { } ... Finally i embedded this class into Person ENTITY @Entity public class Person implements Serializable { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id; private String name; private String surname; @Embedded private Address address; public Person() { } ... All works good when i have to save a new Person record, in fact hibernate creates a PERSON_TABLE as i want, but if i try to retrieve a Person record i have an exception. HQL is simply "from Person" The excpetion is (Entities is the package containing all classes above-mentioned): org.hibernate.AnnotationException: @OneToOne or @ManyToOne on Entities.Person.address.municipality references an unknown entity: Entities.Municipality Is the @OneToOne annotation the problem? Thanks.

  • Weird output of Throwable getMessage()

    - by Ravi Gupta
    Hi I have below pseudo code with throws an exception like this throw new MyException("Bad thing happened","com.stuff.errorCode"); where MyException extends Exception class. So the problem is when I try to get the message from MyException class by calling myEx.getMessage() it returns ???en_US.Bad thing happened??? instead of my original message i.e. Bad thing happened I have checked that MyException class doesn't overrides Throwable class's getMessage() behavior. Below is the how the call passes from MyException.getMessage() to Throwable.getMessage() public MyException(String msg, String sErrorCode){ super(msg); this.sErrorCode = sErrorCode; this.iSeverity = 0; } which then calls public Exception(String message) { super(message); } and finally public Throwable(String message) { fillInStackTrace(); detailMessage = message; } when I do a getMessage on myexception it calls Throwable's getMessage as below public String getMessage() { return detailMessage; } So ideally it should return the original message as I set when throwing the exception. What's the ???en_US thing ?

  • Pass Alot of Parameters on a Form to Action Struts2

    - by Neeraj
    I have been working on migrating a web application from Struts1 to Struts2. I have a simple Form with around 45 Fields (basically a grid with data). I have to capture all those in Struts2 Action.I noticed that in struts2 we have OGNL through which we just write getters setters in action itself by declaring fields locally to get those variables flowing in the request. I cannot write 45 getters/setters in my action, there must be a way to pass whole object(a POJO) from jsp to Action layer. In Struts 1, we normally get a ActionForm Object and/or get request parameters in a map and then populate. Any help or suggestions will be appreciated.

  • How does the event dispatch thread work?

    - by Roman
    With the help of people on stackoverflow I was able to get the following working code of the simples GUI countdown (it just displays a window counting down seconds). My main problem with this code is the invokeLater stuff. As far as I understand the invokeLater send a task to the event dispatching thread (EDT) and then the EDT execute this task whenever it "can" (whatever it means). Is it right? To my understanding the code works like that: In the main method we use invokeLater to show the window (showGUI method). In other words, the code displaying the window will be executed in the EDT. In the main method we also start the counter and the counter (by construction) is executed in another thread (so it is not in the event dispatching thread). Right? The counter is executed in a separate thread and periodically it calls updateGUI. The updateGUI is supposed to update GUI. And GUI is working in the EDT. So, updateGUI should also be executed in the EDT. It is why the code for the updateGUI is inclosed in the invokeLater. Is it right? What is not clear to me is why we call the counter from the EDT. Anyway it is not executed in the EDT. It starts immediately a new thread and the counter is executed there. So, why we cannot call the counter in the main method after the invokeLater block? import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.SwingUtilities; public class CountdownNew { static JLabel label; // Method which defines the appearance of the window. public static void showGUI() { JFrame frame = new JFrame("Simple Countdown"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); label = new JLabel("Some Text"); frame.add(label); frame.pack(); frame.setVisible(true); } // Define a new thread in which the countdown is counting down. public static Thread counter = new Thread() { public void run() { for (int i=10; i>0; i=i-1) { updateGUI(i,label); try {Thread.sleep(1000);} catch(InterruptedException e) {}; } } }; // A method which updates GUI (sets a new value of JLabel). private static void updateGUI(final int i, final JLabel label) { SwingUtilities.invokeLater( new Runnable() { public void run() { label.setText("You have " + i + " seconds."); } } ); } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { public void run() { showGUI(); counter.start(); } }); } }

  • Dynamically refresh JTextArea as processing occurs?

    - by digiarnie
    I am trying to create a very simple Swing UI that logs information onto the screen via a JTextArea as processing occurs in the background. When the user clicks a button, I want each call to: textArea.append(someString + "\n"); to immediately show up in the UI. At the moment, the JTextArea does not show all log information until the processing has completed after clicking the button. How can I get it to refresh dynamically?

  • Synth LaF JLabel DISABLED color

    - by mmoris
    Hi all, Using the Synth LaF, I am unable to set a JLabel's FOREGROUND color for the DISABLED state. has anybody succeeded in doing this? Here is my label's style definition in my LaF.xml file. <style id="whiteLabelStyle"> <opaque value="false"/> <font name="Bitstream Vera Sans" size="16" /> <state> <color type="FOREGROUND" value="WHITE"/> </state> <state value="DISABLED"> <color type="FOREGROUND" value="BLACK"/> </state> </style> <bind style="whiteLabelStyle" type="name" key="WhiteOrbitLabel"/> Please not that all the other styles defined in my LaF.xml file are rendered properly in my application including my label's WHITE normal state color (it just never goes to black when I do lbl.setEnabled(false) Also, going through the Synth code, I have found the following comment in SynthStyle.getColor if ((context.getComponentState() & SynthConstants.DISABLED) != 0) { //This component is disabled, so return the disabled color. //In some cases this means ignoring the color specified by the //developer on the component. In other cases it means using a //specified disabledTextColor, such as on JTextComponents. //For example, JLabel doesn't specify a disabled color that the //developer can set, yet it should have a disabled color to the //text when the label is disabled. This code allows for that. if (c instanceof JTextComponent) { JTextComponent txt = (JTextComponent)c; Color disabledColor = txt.getDisabledTextColor(); if (disabledColor == null || disabledColor instanceof UIResource) { return getColorForState(context, type); } } else if (c instanceof JLabel && (type == ColorType.FOREGROUND || type == ColorType.TEXT_FOREGROUND)){ return getColorForState(context, type); } But I could not figure out how to set a disabled color for a JLabel Thanks for your help!

  • list or container O(1)-ish insertion/deletion performance, with array semantics

    - by Chris Kaminski
    I'm looking for a collection that offers list semantics, but also allows array semantics. Say I have a list with the following items: apple orange carrot pear then my container array would: container[0] == apple container[1] == orangle container[2] == carrot Then say I delete the orange element: container[0] == apple container[1] == carrot I don't particularly care if sort order is maintained, I'd just like the array values to function as accelerators to the list items, and I want to collapse gaps in the array without having to do an explicit resizing.
