  • Need Help Customizing a Grammar Checking Replace Rule in Java

    - by user567785
    Hello, I am currently adding the Khmer (Cambodian) language to LanguageTool, an opensource grammar checker for OpenOffice (http://www.languagetool.org). I don't know enough Java to customize one of the scripts and wanted to make a request here asking if anyone would be willing to customize it for me (I can put link to your website at http://www.sbbic.org/lang/en-us/volunteer/ if you help). Here is the script that needs customization KhmerWordCoherencyRule.java: /* LanguageTool, a natural language style checker * Copyright (C) 2005 Daniel Naber (http://www.danielnaber.de) * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public * License as published by the Free Software Foundation; either * version 2.1 of the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If anyone can help I would be grateful! Thanks for your time, Nathan

  • How do I get my dependenices inject using @Configurable in conjunction with readResolve()

    - by bmatthews68
    The framework I am developing for my application relies very heavily on dynamically generated domain objects. I recently started using Spring WebFlow and now need to be able to serialize my domain objects that will be kept in flow scope. I have done a bit of research and figured out that I can use writeReplace() and readResolve(). The only catch is that I need to look-up a factory in the Spring context. I tried to use @Configurable(preConstruction = true) in conjunction with the BeanFactoryAware marker interface. But beanFactory is always null when I try to use it in my createEntity() method. Neither the default constructor nor the setBeanFactory() injector are called. Has anybody tried this or something similar? I have included relevant class below.

  • ASPX ajax form post help

    - by StealthRT
    Hey all, i have this peice of code that allows a user to select a jpg image, resize it and uploads it to the server driectory. The problem being is that it reloads the aspx page when it saves the image. My question is-is there any way to do this same thing but with ajax so that it doesn't leave the page after submitting it?

  • Windows 7 Seems to break SWT Control.print(GC)

    - by GreenKiwi
    A bug has been filed and fixed (super quickly) in SWT: https://bugs.eclipse.org/bugs/show_bug.cgi?id=305294 Just to preface this, my goal here is to print the two images into a canvas so that I can animate the canvas sliding across the screen (think iPhone), sliding the controls themselves was too CPU intensive, so this was a good alternative until I tested it on Win7. I'm open to anything that will help me solve my original problem, it doesn't have to be fixing the problem below. Does anyone know how to get "Control.print(GC)" to work with Windows 7 Aero? I have code that works just fine in Windows XP and in Windows 7, when Aero is disabled, but the command: control.print(GC) causes a non-top control to be effectively erased from the screen. GC gc = new GC(image); try { // As soon as this code is called, calling "layout" on the controls // causes them to disappear. control.print(gc); } finally { gc.dispose(); } I have stacked controls and would like to print the images from the current and next controls such that I can "slide" them off the screen. However, upon printing the non-top control, it is never redrawn again. Here is some example code. (Interesting code bits are at the top and it will require pointing at SWT in order to work.) Thanks for any and all help. As a work around, I'm thinking about swapping controls between prints to see if that helps, but I'd rather not. import org.eclipse.swt.SWT; import org.eclipse.swt.custom.StackLayout; import org.eclipse.swt.events.SelectionAdapter; import org.eclipse.swt.events.SelectionEvent; import org.eclipse.swt.graphics.GC; import org.eclipse.swt.graphics.Image; import org.eclipse.swt.graphics.Point; import org.eclipse.swt.layout.GridData; import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets.Control; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Label; import org.eclipse.swt.widgets.Shell; public class SWTImagePrintTest { private Composite stack; private StackLayout layout; private Label lblFlip; private Label lblFlop; private boolean flip = true; private Button buttonFlop; private Button buttonPrint; /** * Prints the control into an image * * @param control */ protected void print(Control control) { Image image = new Image(control.getDisplay(), control.getBounds()); GC gc = new GC(image); try { // As soon as this code is called, calling "layout" on the controls // causes them to disappear. control.print(gc); } finally { gc.dispose(); } } /** * Swaps the controls in the stack */ private void flipFlop() { if (flip) { flip = false; layout.topControl = lblFlop; buttonFlop.setText("flop"); stack.layout(); } else { flip = true; layout.topControl = lblFlip; buttonFlop.setText("flip"); stack.layout(); } } private void createContents(Shell shell) { shell.setLayout(new GridLayout(2, true)); stack = new Composite(shell, SWT.NONE); GridData gdStack = new GridData(GridData.FILL_BOTH); gdStack.horizontalSpan = 2; stack.setLayoutData(gdStack); layout = new StackLayout(); stack.setLayout(layout); lblFlip = new Label(stack, SWT.BOLD); lblFlip.setBackground(Display.getCurrent().getSystemColor( SWT.COLOR_CYAN)); lblFlip.setText("FlIp"); lblFlop = new Label(stack, SWT.NONE); lblFlop.setBackground(Display.getCurrent().getSystemColor( SWT.COLOR_BLUE)); lblFlop.setText("fLoP"); layout.topControl = lblFlip; stack.layout(); buttonFlop = new Button(shell, SWT.FLAT); buttonFlop.setText("Flip"); GridData gdFlip = new GridData(); gdFlip.horizontalAlignment = SWT.RIGHT; buttonFlop.setLayoutData(gdFlip); buttonFlop.addSelectionListener(new SelectionAdapter() { @Override public void widgetSelected(SelectionEvent e) { flipFlop(); } }); buttonPrint = new Button(shell, SWT.FLAT); buttonPrint.setText("Print"); GridData gdPrint = new GridData(); gdPrint.horizontalAlignment = SWT.LEFT; buttonPrint.setLayoutData(gdPrint); buttonPrint.addSelectionListener(new SelectionAdapter() { @Override public void widgetSelected(SelectionEvent e) { print(lblFlip); print(lblFlop); } }); } /** * @param args */ public static void main(String[] args) { Shell shell = new Shell(); shell.setText("Slider Test"); shell.setSize(new Point(800, 600)); shell.setLayout(new GridLayout()); SWTImagePrintTest tt = new SWTImagePrintTest(); tt.createContents(shell); shell.open(); Display display = Display.getDefault(); while (shell.isDisposed() == false) { if (display.readAndDispatch() == false) { display.sleep(); } } display.dispose(); } }

  • Threads to make video out of images

    - by masood
    updates: I think/ suspect the imageIO is not thread safe. shared by all threads. the read() call might use resources that are also shared. Thus it will give the performance of a single thread no matter how many threads used. ? if its correct . what is the solution (in practical code) Single request and response model at one time do not utilizes full network/internet bandwidth, thus resulting in low performance. (benchmark is of half speed utilization or even lower) This is to make a video out of an IP cam that gives a new image on each request. http://149.5.43.10:8001/snapshot.jpg It makes a delay of 3 - 8 seconds no matter what I do. Changed thread no. and thread time intervals, debugged the code by System.out.println statements to see if threads work. All seems normal. Any help? Please show some practical code. You may modify mine. This code works (javascript) with much smoother frame rate and max bandwidth usage. but the later code (java) dont. same 3 to 8 seconds gap. <!DOCTYPE html> <html> <head> <script type="text/javascript"> (function(){ var img="/*url*/"; var interval=50; var pointer=0; function showImg(image,idx) { if(idx<=pointer) return; document.body.replaceChild(image,document.getElementsByTagName("img")[0]); pointer=idx; preload(); } function preload() { var cache=null,idx=0;; for(var i=0;i<5;i++) { idx=Date.now()+interval*(i+1); cache=new Image(); cache.onload=(function(ele,idx){return function(){showImg(ele,idx);};})(cache,idx); cache.src=img+"?"+idx; } } window.onload=function(){ document.getElementsByTagName("img")[0].onload=preload; document.getElementsByTagName("img")[0].src="/*initial url*/"; }; })(); </script> </head> <body> <img /> </body> </html> and of java (with problem) : package camba; import java.applet.Applet; import java.awt.Button; import java.awt.Graphics; import java.awt.Image; import java.awt.Label; import java.awt.Panel; import java.awt.TextField; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.net.URL; import java.security.Timestamp; import java.util.Date; import java.util.concurrent.TimeUnit; import java.util.concurrent.atomic.AtomicBoolean; import javax.imageio.ImageIO; public class Camba extends Applet implements ActionListener{ Image img; TextField textField; Label label; Button start,stop; boolean terminate = false; long viewTime; public void init(){ label = new Label("please enter camera URL "); add(label); textField = new TextField(30); add(textField); start = new Button("Start"); add(start); start.addActionListener(this); stop = new Button("Stop"); add(stop); stop.addActionListener(this); } public void actionPerformed(ActionEvent e){ Button source = (Button)e.getSource(); if(source.getLabel() == "Start"){ for (int i = 0; i < 7; i++) { myThread(50*i); } System.out.println("start..."); } if(source.getLabel() == "Stop"){ terminate = true; System.out.println("stop..."); } } public void paint(Graphics g) { update(g); } public void update(Graphics g){ try{ viewTime = System.currentTimeMillis(); g.drawImage(img, 100, 100, this); } catch(Exception e) { e.printStackTrace(); } } public void myThread(final int sleepTime){ new Thread(new Runnable() { public void run() { while(!terminate){ try { TimeUnit.MILLISECONDS.sleep(sleepTime); } catch (InterruptedException ex) { ex.printStackTrace(); } long requestTime= 0; Image tempImage = null; try { URL pic = null; requestTime= System.currentTimeMillis(); pic = new URL(getDocumentBase(), textField.getText()); tempImage = ImageIO.read(pic); } catch(Exception e) { e.printStackTrace(); } if(requestTime >= /*last view time*/viewTime){ img = tempImage; Camba.this.repaint(); } } }}).start(); System.out.println("thread started..."); } }

  • What is the best strategy for populating a TableView from a service?

    - by alrutherford
    I have an application which has a potentially long running background process. I want this process to populate a TableView as results objects are generated. The results objects are added to an observableList and have properties which are bound to the columns in the usual fashion for JavaFX. As an example of this consider the following sample code Main Application import java.util.LinkedList; import javafx.application.Application; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.geometry.Insets; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.control.TableColumn; import javafx.scene.control.TableView; import javafx.scene.control.cell.PropertyValueFactory; import javafx.scene.layout.VBox; import javafx.stage.Stage; public class DataViewTest extends Application { private TableView<ServiceResult> dataTable = new TableView<ServiceResult>(); private ObservableList<ServiceResult> observableList; private ResultService resultService; public static void main(String[] args) { launch(args); } @Override public void start(Stage stage) { observableList = FXCollections.observableArrayList(new LinkedList<ServiceResult>()); resultService = new ResultService(observableList); Button refreshBtn = new Button("Update"); refreshBtn.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent arg0) { observableList.clear(); resultService.reset(); resultService.start(); } }); TableColumn<ServiceResult, String> nameCol = new TableColumn<ServiceResult, String>("Value"); nameCol.setCellValueFactory(new PropertyValueFactory<ServiceResult, String>("value")); nameCol.setPrefWidth(200); dataTable.getColumns().setAll(nameCol); // productTable.getItems().addAll(products); dataTable.setItems(observableList); Scene scene = new Scene(new Group()); stage.setTitle("Table View Sample"); stage.setWidth(300); stage.setHeight(500); final VBox vbox = new VBox(); vbox.setSpacing(5); vbox.setPadding(new Insets(10, 0, 0, 10)); vbox.getChildren().addAll(refreshBtn, dataTable); ((Group) scene.getRoot()).getChildren().addAll(vbox); stage.setScene(scene); stage.show(); } } Service public class ResultService extends Service<Void> { public static final int ITEM_COUNT = 100; private ObservableList<ServiceResult> observableList; /** * Construct service. * */ public ResultService(ObservableList<ServiceResult> observableList) { this.observableList = observableList; } @Override protected Task<Void> createTask() { return new Task<Void>() { @Override protected Void call() throws Exception { process(); return null; } }; } public void process() { for (int i = 0; i < ITEM_COUNT; i++) { observableList.add(new ServiceResult(i)); } } } Data public class ServiceResult { private IntegerProperty valueProperty; /** * Construct property object. * */ public ServiceResult(int value) { valueProperty = new SimpleIntegerProperty(); setValue(value); } public int getValue() { return valueProperty.get(); } public void setValue(int value) { this.valueProperty.set(value); } public IntegerProperty valueProperty() { return valueProperty; } } Both the service and the TableView share a reference to the observable list? Is this good practise in JavaFx and if not what is the correct strategy? If you hit the the 'Update' button the list will not always refresh to the ITEM_COUNT length. I believe this is because the observableList.clear() is interfering with the update which is running in the background thread. Can anyone shed some light on this?

  • How do I import and call unmanaged C dll with ansi string "char *" pointer string from VB.net?

    - by Warren P
    I have written my own function, which in C would be declared like this, using standard Win32 calling conventions: int Thing( char * command, char * buffer, int * BufSize); I have the following amount of VB figured out, which should import the dll and call this function, wrapping it up to make it easy to call Thing("CommandHere",GetDataBackHere): Imports Microsoft.VisualBasic Imports System.Runtime.InteropServices Imports System Imports System.Text Namespace dllInvocationSpace Public Class dllInvoker ' tried attributes but could not make it build: ' <DllImport("Thing1.dll", False, CallingConvention.Cdecl, CharSet.Ansi, "Baton", True, True, False, True)> Declare Ansi Function Thing Lib "Thing1.dll" (ByVal Command As String, ByRef Buffer As String, ByRef BufferLength As Integer) Shared Function dllCall(ByVal Command As String, ByRef Results As String) As Integer Dim Buffer As StringBuilder = New StringBuilder(65536) Dim retCode As Integer Dim bufsz As Integer bufsz = 65536 retCode = Thing(Command, Buffer, bufsz) Results = Buffer Return retCode End Function End Class End Namespace The current code doesn't build, because although I think I should be able to create a "buffer" that the C Dll can write data back into using a string builder, I haven't got it quite right. (Value of type System.Text.STringBuilder cannot be converted to 'String'). I have looked all over the newsgroups and forums and can not find an example where the C dll needs to pass between 1 and 64kbytes of data back (char *buffer, int bufferlen) to visual basic.net.

  • Cannot call DLL import entry in C# from C++ project. EntryPointNotFoundException

    - by kriau
    I'm trying to call from C# a function in a custom DLL written in C++. However I'm getting the warning during code analysis and the error at runtime: Warning: CA1400 : Microsoft.Interoperability : Correct the declaration of 'SafeNativeMethods.SetHook()' so that it correctly points to an existing entry point in 'wi.dll'. The unmanaged entry point name currently linked to is SetHook. Error: System.EntryPointNotFoundException was unhandled. Unable to find an entry point named 'SetHook' in DLL 'wi.dll'. Both projects wi.dll and C# exe has been compiled in to the same DEBUG folder, both files reside here. There is only one file with the name wi.dll in the whole file system. C++ function definition looks like: #define WI_API __declspec(dllexport) bool WI_API SetHook(); I can see exported function using Dependency Walker: as decorated: bool SetHook(void) as undecorated: ?SetHook@@YA_NXZ C# DLL import looks like (I've defined these lines using CLRInsideOut from MSDN magazine): [DllImport("wi.dll", EntryPoint = "SetHook", CallingConvention = CallingConvention.Cdecl)] [return: MarshalAsAttribute(UnmanagedType.I1)] internal static extern bool SetHook(); I've tried without EntryPoint and CallingConvention definitions as well. Both projects are 32-bits, I'm using W7 64 bits, VS 2010 RC. I believe that I simply have overlooked something.... Thanks in advance.

  • is concatenating the only way to 'import' one JS lib from another?

    - by Nikita
    Disclaimer: JS novice I have a JS widget that depends on JQuery. The widget's going to be embedded in a 3rd party site but I figure out how to avoid declaring dependency on jquery on the widget-hosting page: 3rd party's page: <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"></script> <script type="text/javascript" src="http://mydomain/mywidget.js"></script> </head> mywidget.js jQuery(document).ready(function() { //do stuff }); I'd rather not include jquery.js in the 3d party page but express the dependency inside mywidget.js (so i can change this dependency or add/remove others w/o having to update the widget-hosting page) I tried adding: var script = document.createElement('script'); script.src = 'http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js'; script.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(script); to the top of mywidget.js but that didn't work - jquery.js did load on page load but "jQuery" was not recognized. What did work was concatenating jquery.js and mywidget.js into a single .js file. But that seems kind of lame - is there no equivalent to? import com.jquery.*; thanks!

  • Why won't EF4 generate a method to support my Function Import?

    - by Deane
    I have a stored proc in my database which returns an integer. I added a Function Import to my model. This appears in the EDMX file: <Function Name="GetTotalEntityCount" Aggregate="false" BuiltIn="false" NiladicFunction="false" IsComposable="false" ParameterTypeSemantics="AllowImplicitConversion" Schema="dbo" /> However, no method actually gets generated for this. It should be top level, right? using (MyContext context = new MyContext()) { context.MyMethodShouldBeRightHere(); } Nothing appears in Intellisense, I've gone through the designer.cs file and there's nothing in there, and reflected the DLL...nothing. The code generator is just not generating any code to support this stored proc. I added another table to my database and updated the model, and that came in, so the model will update, it's just specifically ignoring this stored proc. I've tried everything I can think of, and consulted every resource I can find, and as near as I can tell, I'm doing everything right. I'm using EF4, database-first. (I'm pretty sure on the version, anyway. This shows up in the generated file: Runtime Version:4.0.30319.1 )

  • Elegant way to import XHTML nodes from xhr.responseXML into HTML document in IE?

    - by Weston Ruter
    While navigating through a site, I'm dynamically loading pages via Ajax and then only updating the elements of the page that are changed, such as the navigation state and main content area. This is similar to Lala. I am serving the site as XHTML in order to be able to have access to xhr.responseXML which I then traverse in parallel with the current document and copy the nodes over. This works very well in browsers other than IE. For IE, I have to iterate over all of the properties of each XML element I want to import into the HTML document to create it from scratch (using a function convertXMLElementToHTML()). Here's the code I'm currently using: try { nodeB = document.importNode(nodeB, true); } catch(e){ nodeB = nodeB.cloneNode(true); if(document.adoptNode) document.adoptNode(nodeB); } try { //This works in all browsers other than IE nodeA.parentNode.replaceChild(nodeB, nodeA); } //Manually clone the nodes into HTML; required for IE catch(e){ nodeA.parentNode.replaceChild(convertXMLElementToHTML(nodeB), nodeA); } Is there a more elegant solution to mirror-translating XML nodes into HTML?

  • Implement OAuth in Java

    - by phineas
    I made an an attempt to implement OAuth for my programming idea in Java, but I failed miserably. I don't know why, but my code doesn't work. Every time I run my program, an IOException is thrown with the reason "java.io.IOException: Server returned HTTP response code: 401" (401 means Unauthorized). I had a close look at the docs, but I really don't understand why it doesn't work. My OAuth provider I wanted to use is twitter, where I've registered my app, too.

  • Why does windows XP minimize my swing full screen window on my second screen ?

    - by Laurent K
    Hello dear fellows, In the application I'm developping (in Java/swing), I have to show a full screen window on the second screen of the user. I did this using a code similar to the one you'll find below... Be, as soon as I click in a window opened by windows explorer, or as soon as I open windows explorer (i'm using windows XP), the full screen window is minimized... Do you know any way or workaround to fix this problem, or is there something important I did not understand with full screen windows?

  • Tomcat does save logged users during restart

    - by mabuzer
    How to force Tomcat to save logged users, so that the they kept logged in even after Tomcat has restarted? Right now the user has to login again everytime. Added the following lines into web-app context.xml: <Manager className="org.apache.catalina.session.PersistentManager"> <Store className="org.apache.catalina.session.FileStore"/> </Manager> but still I see login page after Tomcat restart, I use Tomcat 6.0.26 Update I managed to solve it like this: 1) Make my own extended version of FormAuthentication class: package com.alz.tomcat; import java.io.IOException; import java.security.Principal; import org.apache.catalina.Session; import org.apache.catalina.deploy.LoginConfig; import org.apache.catalina.connector.Request; import org.apache.catalina.connector.Response; import org.apache.catalina.authenticator.Constants; import org.apache.catalina.authenticator.FormAuthenticator; /** * * @author mabuzer */ public class Authenticator extends FormAuthenticator { @Override public boolean authenticate(Request request, Response response, LoginConfig config) throws IOException { String username = (String) request.getSession().getAttribute("USERNAME"); String password = (String) request.getSession().getAttribute("PASSWORD"); Principal principal = request.getUserPrincipal(); Session session = request.getSessionInternal(true); if (request.getUserPrincipal() == null && !isNull(username) && !isNull(password)) { principal = context.getRealm().authenticate(username, password); if (principal != null) { session.setNote(Constants.FORM_PRINCIPAL_NOTE, principal); if (!matchRequest(request)) { register(request, response, principal, Constants.FORM_METHOD, username, password); return (true); } } return super.authenticate(request, response, config); } else { return super.authenticate(request, response, config); } } private boolean isNull(String str) { if (str == null || "".equals(str)) { return true; } else { return false; } } } 2) Have your own ContextConfig class: package com.alz.tomcat; import java.util.HashMap; import org.apache.catalina.Valve; /** * * @author [email protected] */ public class ContextConfig extends org.apache.catalina.startup.ContextConfig { public ContextConfig() { super(); // we need to append our authenticator setCustomAuthenticators(customAuthenticators); customAuthenticators = new HashMap(); customAuthenticators.put("Authenticator" , new Authenticator()); } } 3) Have a class extends LifeCycleListener to set replace default ContextConfig the one you made: package com.alz.tomcat; import org.apache.catalina.Lifecycle; import org.apache.catalina.LifecycleEvent; import org.apache.catalina.core.StandardHost; /** * * @author [email protected] */ public class LifeCycleListener implements org.apache.catalina.LifecycleListener { public void lifecycleEvent(LifecycleEvent lifeCycleEvent) { if (Lifecycle.BEFORE_START_EVENT.equals(lifeCycleEvent.getType())) { StandardHost aStandardHost = (StandardHost) lifeCycleEvent.getLifecycle(); aStandardHost.setConfigClass("com.alz.tomcat.ContextConfig"); } } } 4) Final step which is to add your LifeCycleListener to server.xml in Host tag like this: <Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true" xmlNamespaceAware="false" xmlValidation="false"> <Listener className="com.alz.tomcat.LifeCycleListener"/> </Host>
