  • [WPF] When Should I Retrieve Values from Textbox?

    - by they_soft
    Suppose I have a Window with TextBoxes I want to use the values. Right now I'm thinking of either: 1) Updating each associated value once the cursor is out of focus, and once the user presses Ok I start the program 2) Once the user presses Ok, I retrieve all the values at once then start the program I'm not sure which one is better though. First alternative seems more modular, but there's more semantic coupling since I each new box is supposed to be updating its respective value. I realize this isn't all that important, but I'm trying to understand when to centralize and when not to. Other better approachers are appreciated too.

  • How do I get the PreviewDialog of Apache FOP to actually display my document?

    - by JRSofty
    Search as I may I have not found a solution to my problem here and I'm hoping the combined minds of StackOverflow will push me in the right direction. My problem is as follows, I'm developing a print and print preview portion of a messaging system's user agent. I was given specific XSLT templates that after transforming XML will produce a Formatting Objects document. With Apache FOP I've been able to render the FO document into PDF which is all fine and good, but I would also like to display it in a print preview dialog. Apache FOP contains such a class called PreviewDialog which requires in its constructor a FOUserAgent, which I can generate, and an object implementing the Renderable Interface. The Renderable Interface has one implementing class in the FOP package which is called InputHandler which takes in its constructor a standard io File object. Now here is where the trouble begins. I'm currently storing the FO document as a temp file and pass this as a File object to an InputHandler instance which is then passed to the PreviewDialog. I see the dialog appear on my screen and along the bottom in a status bar it says that it is generating the document, and that is all it does. Here is the code I'm trying to use. It isn't production code so it's not pretty: import java.io.BufferedOutputStream; import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStream; import java.util.Random; import javax.xml.transform.Result; import javax.xml.transform.Source; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerConfigurationException; import javax.xml.transform.TransformerException; import javax.xml.transform.TransformerFactory; import javax.xml.transform.sax.SAXResult; import javax.xml.transform.stream.StreamResult; import javax.xml.transform.stream.StreamSource; import org.apache.fop.apps.FOPException; import org.apache.fop.apps.FOUserAgent; import org.apache.fop.apps.Fop; import org.apache.fop.apps.FopFactory; import org.apache.fop.cli.InputHandler; import org.apache.fop.render.awt.viewer.PreviewDialog; public class PrintPreview { public void showPreview(final File xslt, final File xmlSource) { boolean err = false; OutputStream out = null; Transformer transformer = null; final String tempFileName = this.getTempDir() + this.generateTempFileName(); final String tempFoFile = tempFileName + ".fo"; final String tempPdfFile = tempFileName + ".pdf"; System.out.println(tempFileName); final TransformerFactory transformFactory = TransformerFactory .newInstance(); final FopFactory fopFactory = FopFactory.newInstance(); try { transformer = transformFactory .newTransformer(new StreamSource(xslt)); final Source src = new StreamSource(xmlSource); out = new FileOutputStream(tempFoFile); final Result res = new StreamResult(out); transformer.transform(src, res); System.out.println("XSLT Transform Completed"); } catch (final TransformerConfigurationException e) { err = true; e.printStackTrace(); } catch (final FileNotFoundException e) { err = true; e.printStackTrace(); } catch (final TransformerException e) { err = true; e.printStackTrace(); } finally { if (out != null) { try { out.close(); } catch (final IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } System.out.println("Initializing Preview"); transformer = null; out = null; final File fo = new File(tempFoFile); final File pdf = new File(tempPdfFile); if (!err) { final FOUserAgent ua = fopFactory.newFOUserAgent(); try { transformer = transformFactory.newTransformer(); out = new FileOutputStream(pdf); out = new BufferedOutputStream(out); final Fop fop = fopFactory.newFop( MimeConstants.MIME_PDF, ua, out); final Source foSrc = new StreamSource(fo); final Result foRes = new SAXResult(fop.getDefaultHandler()); transformer.transform(foSrc, foRes); System.out.println("Transformation Complete"); } catch (final FOPException e) { err = true; e.printStackTrace(); } catch (final FileNotFoundException e) { err = true; e.printStackTrace(); } catch (final TransformerException e) { err = true; e.printStackTrace(); } finally { if (out != null) { try { out.close(); } catch (final IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } if (!err) { System.out.println("Attempting to Preview"); final InputHandler inputHandler = new InputHandler(fo); PreviewDialog.createPreviewDialog(ua, inputHandler, true); } } // perform the clean up // f.delete(); } private String getTempDir() { final String p = "java.io.tmpdir"; return System.getProperty(p); } private String generateTempFileName() { final String charset = "abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890"; final StringBuffer sb = new StringBuffer(); Random r = new Random(); int seed = r.nextInt(); r = new Random(seed); for (int i = 0; i < 8; i++) { final int n = r.nextInt(71); seed = r.nextInt(); sb.append(charset.charAt(n)); r = new Random(seed); } return sb.toString(); } } Any help on this would be appreciated.

  • A "Trig" Calculating Class

    - by Clinton Scott
    I have been trying to create a gui that calculates trigonometric functions based off of the user's input. I have had success in the GUI part, but my class that I wrote to hold information using inheritance seems to be messed up, because when I run it gives an error saying: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - constructor ArcTrigCalcCon in class TrigCalc.ArcTrigCalcCon cannot be applied to given types; required: double,double,double,double,double,double found: java.lang.Double,java.lang.Double,java.lang.Double reason: actual and formal argument lists differ in length at TrigCalc.TrigCalcGUI.(TrigCalcGUI.java:31) at TrigCalc.TrigCalcGUI.main(TrigCalcGUI.java:87) Java Result: 1 and says it is the object causing the problem. Below Will be my code. First I will put up my inheritance class with cosecant secant and cotangent and then my original class with the original 3 trig functions: { public ArcTrigCalcCon(double s, double cs, double t, double csc, double sc, double ct) { // Inherit from the Trig Calc class super(s, cs, t); cosecant = 1/s; secant = 1/cs; cotangent = 1/t; } public void setCsc(double csc) { cosecant = csc; } public void setSec(double sc) { secant = sc; } public void setCot(double ct) { cotangent = ct; } } Here is the first Trigonometric class: public class TrigCalcCon { public double sine; public double cosine; public double tangent; public TrigCalcCon(double s, double cs, double t) { sine = s; cosine = cs; tangent = t; } public void setSin(double s) { sine = s; } public void setCos(double cs) { cosine = cs; } public void setTan(double t) { tangent = t; } public void set(double s, double cs, double t) { sine = s; cosine = cs; tangent = t; } public double getSin() { return Math.sin(sine); } public double getCos() { return Math.cos(cosine); } public double getTan() { return Math.tan(tangent); } } and here is the demo class to run the gui: public class TrigCalcGUI extends JFrame implements ActionListener { // Instance Variables private String input; private Double s, cs, t, csc, sc, ct; private JPanel mainPanel, sinPanel, cosPanel, tanPanel, cscPanel, secPanel, cotPanel, buttonPanel, inputPanel, displayPanel; // Panel Display private JLabel sinLabel, cosLabel, tanLabel, secLabel, cscLabel, cotLabel, inputLabel;

  • For Loop help In a Hash Cracker Homework.

    - by aaron burns
    On the homework I am working on we are making a hash cracker. I am implementing it so as to have my cracker. java call worker.java. Worker.java implements Runnable. Worker is to take the start and end of a list of char, the hash it is to crack, and the max length of the password that made the hash. I know I want to do a loop in run() BUT I cannot think of how I would do it so it would go to the given max pasword length. I have posted the code I have so far. Any directions or areas I should look into.... I thought there was a way to do this with a certain way to write the loop but I don't know or can't find the correct syntax. Oh.. also. In main I divide up so x amount of threads can be chosen and I know that as of write now it only works for an even number of the 40 possible char given. package HashCracker; import java.util.*; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; public class Cracker { // Array of chars used to produce strings public static final char[] CHARS = "abcdefghijklmnopqrstuvwxyz0123456789.,-!".toCharArray(); public static final int numOfChar=40; /* Given a byte[] array, produces a hex String, such as "234a6f". with 2 chars for each byte in the array. (provided code) */ public static String hexToString(byte[] bytes) { StringBuffer buff = new StringBuffer(); for (int i=0; i<bytes.length; i++) { int val = bytes[i]; val = val & 0xff; // remove higher bits, sign if (val<16) buff.append('0'); // leading 0 buff.append(Integer.toString(val, 16)); } return buff.toString(); } /* Given a string of hex byte values such as "24a26f", creates a byte[] array of those values, one byte value -128..127 for each 2 chars.

  • Why doesn't JFreeCharts correctly connect the points in my xy-line graph?

    - by Javajava
    /Each letter A,T,G,C represents a direction for the plot to graph. Specifically, “A” means move right, “T” is move down, “C” is move up, and “G” is move left.

  • Play 2.0 javaToDo tutorial doesn't compile

    - by chsn
    I'm trying to follow the Play2.0 JavaToDO tutorial and for some reason it just doesn't want to work. Have looked through stackoverflow and other online resources, but haven't find an answer to this and it's driving me crazy. Attached code of the Application.java package controllers; import models.Task; import play.data.Form; import play.mvc.Controller; import play.mvc.Result; public class Application extends Controller { static Form<Task> taskForm = form(Task.class); public static Result index() { return redirect(routes.Application.tasks()); } public static Result tasks() { return ok( views.html.index.render(Task.all(), taskForm)); } public static Result newTask() { return TODO; } public static Result deleteTask(Long id) { return TODO; } } Attached code of the Task java package models; import java.util.List; import javax.persistence.Entity; import play.data.Form; import play.data.validation.Constraints.Required; import play.db.ebean.Model.Finder; import play.mvc.Result; import controllers.routes; @Entity public class Task { public Long id; @Required public String label; // search public static Finder<Long,Task> find = new Finder( Long.class, Task.class); // display tasks public static List<Task> all() { return find.all(); } // create task public static void create(Task task) { task.create(task); } // delete task public static void delete(Long id) { find.ref(id).delete(id); // find.ref(id).delete(); } // create new task public static Result newTask() { Form<Task> filledForm = taskForm.bindFromRequest(); if(filledForm.hasErrors()) { return badRequest( views.html.index.render(Task.all(), filledForm) ); } else { Task.create(filledForm.get()); return redirect(routes.Application.tasks()); } } } I get a compile error on Task.java on the line static Form<Task> taskForm = form(Task.class); As I'm working on eclipse (the project is eclipsified before import), it's telling me that taskForm cannot be resolved and it also underlines every play 2 command e.g. "render(), redirect(), bindFromRequest()" asking me to create a method for it. Any ideas how to solve the compilations error and also how to get Eclipse to recognize the play2 commands? EDIT: updated Application.java package controllers; import models.Task; import play.data.Form; import play.mvc.Controller; import play.mvc.Result; public class Application extends Controller { // create new task public static Result newTask() { Form<Task> filledForm = form(Task.class).bindFromRequest(); if(filledForm.hasErrors()) { return badRequest( views.html.index.render(Task.all(), filledForm) ); } else { Task.newTask(filledForm.get()); return redirect(routes.Application.tasks()); } } public static Result index() { return redirect(routes.Application.tasks()); } public static Result tasks() { return ok( views.html.index.render(Task.all(), taskForm)); } public static Result deleteTask(Long id) { return TODO; } } Updated task.java package models; import java.util.List; import javax.persistence.Entity; import play.data.Form; import play.data.validation.Constraints.Required; import play.db.ebean.Model; import play.db.ebean.Model.Finder; import play.mvc.Result; import controllers.routes; @Entity public class Task extends Model { public Long id; @Required public String label; // Define a taskForm static Form<Task> taskForm = form(Task.class); // search public static Finder<Long,Task> find = new Finder( Long.class, Task.class); // display tasks public static List<Task> all() { return find.all(); } // create new task public static Result newTask(Task newTask) { save(task); } // delete task public static void delete(Long id) { find.ref(id).delete(id); // find.ref(id).delete(); } }

  • How to copy files while keeping directory structure?

    - by Cubic
    This is for a java project, but the same concept can be applied more generally: Basically, I have a projects with all *.java files located in some sub directory of src. Now I want to grab all directories with the name test in that directory tree and move them into a new directory called tests, e.g.: src->com->a1 -> A.java -> B.java -> test -> test1.java -> test2.java to src->com->a1 -> A.java -> B.java tests->com->a1->test -> test1.java -> test2.java How would I best do that?

  • What is the right approach to use adsense with responsive web design?

    - by Sisir
    Recently I was studying responsive design a lot and designed couple of sites. But i was wondering how would I use google adsense (which is pixel based) ads on my responsive design? Very typical example is suppose I have a 728x90 ads on header. Or if i do a mobile first approach i would need different versions of ad sizes for different view posts but google doesn't allow more than three ad unit per page (as far as i know). So, Question: What is the right approach/best practice of using google adsense on a responsive site design?

  • Peut-on réaliser un bon design Web sans Web-designer ? Quelques pistes de réflexions pour tenter d'y arriver

    Le design des sites aujourd'hui est un point "critique". Et bien souvent les utilisateurs préfèreront un "beau" site à son concurrent moins "évolué" graphiquement. Malheureusement, il n'est pas toujours possible d'avoir à ses côtés un web designer. Dans ce cas, il faut se retrousser les manches et tenter de faire du mieux que l'on peut. Savoir créer un design attrayant ne s'apprend pas en quelques lignes. Cependant voici un petit guide pour débutant qui vous aidera dans la création de votre graphisme. Les contraintes sont nécessaires Même si ça peut sembler contre-intuitif, un bon design part toujours de contraintes bien établies. Si vous pensez que votre projet n'...

  • Most regrettable design or programming decision you made? [closed]

    - by VNarasimhaM
    I would like to hear what kind of design decisions you took and how did they backfire. Because of a bad design decision, I ended up having to support that bad decision forever (I also had a part in it). This made me realize that one single design mistake can haunt you forever. I want to learn from the more experienced people what kind of blunders have they experienced and what did they learn from them. I'm sure this will be a lot of help to other programmers by helping them to not repeat those decisions. Thanks for sharing your experience.

While trying to upload a video in Android, I'm reading it into memory, and if the video is large I get an OutOfMemoryError. Here's my code: // get bytestream to upload videoByteArray = getBytesFromFile(cR, fileUriString); public static byte[] getBytesFromFile(ContentResolver cR, String fileUriString) throws IOException { Uri tempuri = Uri.parse(fileUriString); InputStream is = cR.openInputStream(tempuri); byte[] b3 = readBytes(is); is.close(); return b3; } public static byte[] readBytes(InputStream inputStream) throws IOException { ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream(); // this is storage overwritten on each iteration with bytes int bufferSize = 1024; byte[] buffer = new byte[bufferSize]; int len = 0; while ((len = inputStream.read(buffer)) != -1) { byteBuffer.write(buffer, 0, len); } return byteBuffer.toByteArray(); } And here's the traceback (the error is thrown on the byteBuffer.write(buffer, 0, len) line): 04-08 11:56:20.456: ERROR/dalvikvm-heap(6088): Out of memory on a 16775184-byte allocation. 04-08 11:56:20.456: INFO/dalvikvm(6088): "IntentService[UploadService]" prio=5 tid=17 RUNNABLE 04-08 11:56:20.456: INFO/dalvikvm(6088): | group="main" sCount=0 dsCount=0 s=N obj=0x449a3cf0 self=0x38d410 04-08 11:56:20.456: INFO/dalvikvm(6088): | sysTid=6119 nice=0 sched=0/0 cgrp=default handle=4010416 04-08 11:56:20.456: INFO/dalvikvm(6088): at java.io.ByteArrayOutputStream.expand(ByteArrayOutputStream.java:~93) 04-08 11:56:20.456: INFO/dalvikvm(6088): at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:218) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.readBytes(UploadService.java:199) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.getBytesFromFile(UploadService.java:182) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.doUploadinBackground(UploadService.java:118) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.onHandleIntent(UploadService.java:85) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:30) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.Handler.dispatchMessage(Handler.java:99) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.Looper.loop(Looper.java:123) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.HandlerThread.run(HandlerThread.java:60) 04-08 11:56:20.467: WARN/dalvikvm(6088): threadid=17: thread exiting with uncaught exception (group=0x4001b180) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): Uncaught handler: thread IntentService[UploadService] exiting due to uncaught exception 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): java.lang.OutOfMemoryError 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at java.io.ByteArrayOutputStream.expand(ByteArrayOutputStream.java:93) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:218) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.readBytes(UploadService.java:199) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.getBytesFromFile(UploadService.java:182) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.doUploadinBackground(UploadService.java:118) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.onHandleIntent(UploadService.java:85) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:30) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.Handler.dispatchMessage(Handler.java:99) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.Looper.loop(Looper.java:123) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.HandlerThread.run(HandlerThread.java:60) 04-08 11:56:20.496: INFO/Process(4657): Sending signal.

Or can I load the bytestream into memory in chunks, and glue it together in the Android code? If anyone could give me a clue as to the best approach, I would be very grateful.

    Ok, so I've finally bowed to peer pressure and started using Spring in my web app :-)... So I'm trying to get the transaction handling stuff to work, and I just can't seem to get it. My Spring configuration looks like this: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <bean id="groupDao" class="mil.navy.ndms.conops.common.dao.impl.jpa.GroupDao" lazy-init="true"> <property name="entityManagerFactory" ><ref bean="entityManagerFactory"/></property> </bean> <!-- enables interpretation of the @Required annotation to ensure that dependency injection actually occures --> <bean class="org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor"/> <!-- enables interpretation of the @PersistenceUnit/@PersistenceContext annotations providing convenient access to EntityManagerFactory/EntityManager --> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/> <!-- uses the persistence unit defined in the META-INF/persistence.xml JPA configuration file --> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="CONOPS_PU" /> </bean> <!-- transaction manager for use with a single JPA EntityManagerFactory for transactional data access to a single datasource --> <bean id="jpaTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory"/> </bean> <!-- enables interpretation of the @Transactional annotation for declerative transaction managment using the specified JpaTransactionManager --> <tx:annotation-driven transaction-manager="jpaTransactionManager" proxy-target-class="true"/> </beans> persistence.xml: <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="CONOPS_PU" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> ...

  • round off and displaying the values

    - by S.PRATHIBA
    Hi all, I have the following code: import java.io.; import java.sql.; import java.math.; import java.lang.; public class Testd1{ public static void main(String[] args) { System.out.println("Sum of the specific column!"); Connection con = null; int m=1; double sum,sum1,sum2; int e[]; e=new int[100]; int p; int decimalPlaces = 5; for( int i=0;i< e.length;i++) { e[i]=0; } double b2,c2,d2,u2,v2; int i,j,k,x,y; double mat[][]=new double[10][10]; try { Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection ("jdbc:mysql://localhost:3306/prathi","root","mysql"); try{ Statement st = con.createStatement(); ResultSet res = st.executeQuery("SELECT Service_ID,SUM(consumer_feedback) FROM consumer1 group by Service_ID"); while (res.next()){ int data=res.getInt(1); System.out.println(data); System.out.println("\n\n"); int c1 = res.getInt(2); e[m]=res.getInt(2); if(e[m]<0) e[m]=0; m++; System.out.print(c1); System.out.println("\t\t"); } sum=e[1]+e[2]+e[3]+e[4]+e[5]; System.out.println("\n \n The sum is" +sum); for( p=21; p<=25; p++) { if(e[p] != 0) e[p]=e[p]/(int)sum; //I have type casted sum to get output BigDecimal bd1 = new BigDecimal(e[p]); bd1 = bd1.setScale(decimalPlaces, BigDecimal.ROUND_HALF_UP); // setScale is immutable e[p] = bd1.intValue(); System.out.println("\n\n The normalized value is" +e[p]); mat[4][p-21]=e[p]; } } catch (SQLException s){ System.out.println("SQL statement is not executed!"); } } catch (Exception e1){ e1.printStackTrace(); } } } I have a table named consumer1.After calculating the sum i am getting the values as follows mysql select Service_ID,sum(consumer_feedback) from consumer1 group by Service_ ID; Service_ID sum(consumer_feedback) 31 17 32 0 33 60 34 38 35 | 38 In my program I am getting the sum for each Service_ID correctly.But,after normalization ie while I am calculating 17/153=0.111 I am getting the normalized value is 0.I want the normalized values to be displayed correctly after rounding off.My output is as follows C:javac Testd1.java C:java Testd1 Sum of the specific column! 31 17 32 0 33 60 34 38 35 38 The sum is153.0 The normalized value is0 The normalized value is0 The normalized value is0 The normalized value is0 The normalized value is0 But,after normalization i want to get 17/153=0.111 I am getting the normalized value is 0.I want these values to be rounded off.

  • JSTL c:forEach causes @ViewScoped bean to invoke @PostConstruct on every request

    - by Nitesh Panchal
    Hello, Again i see that the @PostConstruct is firing every time even though no binding attribute is used. See this code :- <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:c="http://java.sun.com/jsp/jstl/core"> <h:head> <title>Facelet Title</title> </h:head> <h:body> <h:form> <c:forEach var="item" items="#{TestBean.listItems}"> <h:outputText value="#{item}"/> </c:forEach> <h:commandButton value="Click" actionListener="#{TestBean.actionListener}"/> </h:form> </h:body> </html> And this is the simplest possible bean in JSF :- package managedBeans; import java.io.Serializable; import java.util.ArrayList; import java.util.List; import javax.annotation.PostConstruct; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; @ManagedBean(name="TestBean") @ViewScoped public class TestBean implements Serializable { private List<String> listItems; public List<String> getListItems() { return listItems; } public void setListItems(List<String> listItems) { this.listItems = listItems; } public TestBean() { } @PostConstruct public void init(){ System.out.println("Post Construct fired!"); listItems = new ArrayList<String>(); listItems.add("Mango"); listItems.add("Apple"); listItems.add("Banana"); } public void actionListener(){ System.out.println("Action Listener fired!"); } } Do you see any behaviour that should cause postconstruct callback to fire each time? I think JSF 2.0 is highly unstable. If it has to fire PostConstruct each and every time what purpose does @ViewScoped serve. Why not to use @RequestScoped only? I thought i have made some mistake in my application. But when i created this simplest possible in JSF, i still get this error. Am i not understanding the scopes of JSF? or are they not testing it properly? Further, if you remove c:forEach and replace it with ui:repeat, then it works fine. Waiting for replies to confirm whether it is bug or it is intentional to stop the programmers from using jstl?

  • How the JOptionPane works

    - by DevAno1
    How can I control what happens with window after clicking JOPtionPane buttons ? I'm trying to implement simple file chooser. In my frame I have 3 buttons (OK, Cancel, Browse). Browse button opens file search window, and after picking files should return to main frame. Clicking OK will open a frame with the content of the file. Now porblem looks this way. With the code below, I can choose file but directly after that a new frame is created, and my frame with buttons dissapears : import java.io.File; import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.awt.*; import javax.swing.*; import java.io.*; public class Main { public static void main(String args[]) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { show("Window"); } }); } public static void show(String frame_name){ JFrame frame = new JFrame(frame_name); frame.setPreferredSize(new Dimension(450, 300)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel top = new JPanel(); top.setLayout(new BoxLayout(top, BoxLayout.Y_AXIS)); JFileChooser fc = new JFileChooser(new File(".")); JPanel creator = new JPanel(); creator.setLayout(new BoxLayout(creator, BoxLayout.Y_AXIS)); creator.add(top); String[] buttons = {"OK", "Cancel", "Browse"}; int rc = JOptionPane.showOptionDialog( null, creator, frame_name, JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, buttons, buttons[0] ); String approveButt = ""; switch(rc){ case 0: break; case 1: break; case 2: approveButt = buttons[rc]; int retVal = fc.showDialog(null, approveButt); if (retVal == JFileChooser.APPROVE_OPTION) System.out.println(approveButt + " " + fc.getSelectedFile()); break; } frame.pack(); frame.setVisible(true); } } With the second code I can return to my menu, but in no way I am able to pop this new frame, which appeared with first code. How to control this ? What am I missing ? public class Main { public static void main(String args[]) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { show("Window"); } }); } public static void show(String frame_name){ JFrame frame = new JFrame(frame_name); frame.setPreferredSize(new Dimension(450, 300)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel top = new JPanel(); top.setLayout(new BoxLayout(top, BoxLayout.Y_AXIS)); JFileChooser fc = new JFileChooser(new File(".")); JPanel creator = new JPanel(); creator.setLayout(new BoxLayout(creator, BoxLayout.Y_AXIS)); creator.add(top); String[] buttons = {"OK", "Cancel", "Browse"}; String approveButt = ""; Plane m = null; int rc = -1; while (rc != 0) { rc = JOptionPane.showOptionDialog( null, creator, frame_name, JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, buttons, buttons[0] ); switch (rc) { case 0: m = new Plane(); case 1: System.exit(0); case 2: approveButt = buttons[rc]; int retVal = fc.showDialog(null, approveButt); if (retVal == JFileChooser.APPROVE_OPTION) System.out.println(approveButt + " " + fc.getSelectedFile()); break; default: break; } } addComponents(frame.getContentPane(), m); frame.pack(); frame.setVisible(true); } private static void addComponents(Container c, Plane e) { c.setLayout(new BoxLayout(c, BoxLayout.Y_AXIS)); c.add(e); } } class Plane extends JPanel { public Plane(){ } @Override public void paint(Graphics g){ g.setColor(Color.BLUE); g.fillRect(0, 0, 400, 250); } }
