  • Reading string value from Excel with HSSF but it's double

    - by egaga
    Hi, I'm using HSSF-POI for reading excel data. The problem is I have values in a cell that look like a number but really are strings. If I look at the format cell in Excel, it says the type is "text". Still the HSSF Cell thinks it's numeric. How can I get the value as a string? If I try to use cell.getRichStringValue, I get exception; if cell.toString, it's not the exact same value as in Excel sheet. Thanks! edit: until this gets resolved, I'll use new BigDecimal(cell.getNumericCellValue()).toString()

  • How do I determine if a JDialog has children?

    - by Morinar
    I've got a custom window class that is a couple levels down extending a JDialog. We have windows that we create and sometimes we create new windows as children of existing windows using the constructor that takes a parent argument. I need to put some code somewhere in our custom class that does something different depending on whether not the window has children. I know of getParent(), etc, and I can see that I can loop through the components of the window, but for the life of me, I can't seem to figure out how to determine whether or not my current window has any child windows. Is there a way to do this? Any help is, as always, much appreciated.

  • How to emulate "-lib foo.jar" from _within_ build.xml

    - by Thorbjørn Ravn Andersen
    By specifying "-lib foo.jar" to ant I get the behaviour that the classes in foo.jar is added to the ant classloader and are available for various tasks taking a class name argument. I'd like to be able to specify the same behaviour but only from inside build.xml (so we can do this on a vanilla ant). For taskdefs we have functioning code looking like: <taskdef resource="net/sf/antcontrib/antlib.xml" description="for/foreach tasks"> <classpath> <pathelement location="${active.workspace}/ant-contrib-1.X/lib/ant-contrib.jar" /> </classpath> </taskdef> where the definition is completely provided from the ant-contrib.jar listed. What is the equivalent mechanism for the "global" ant classpath? (I have thought out that this is the way to get <javac> use ecj-3.5.jar to compile with on a JRE - http://stackoverflow.com/questions/2364006/specifying-the-eclipse-compiler-completely-from-within-build-xml - in a way compatible with ant 1.7. Better suggestions are welcome :) EDIT: It appears that the about-to-be-released version 1.0 of ant4eclipse includes ecj. This does not answer the question, but may solve my basic problem.

  • Hibernate criteria -- alias

    - by Ignace
    Hello, I'm struggling a bit with the concept of alias in Hibernate. My situation is the following: Order @OneToMany(cascade=CascadeType.ALL,mappedBy="m_order") private Set<OrderDetail> m_details; OrderDetail @ManyToOne(cascade=CascadeType.ALL) @JoinColumn(name="product_id") private Product m_product; @ManyToOne(cascade=CascadeType.ALL) @JoinColumn(name="order_id") private Order m_order; DAO c.createAlias("m_details", "detail").createCriteria("detail.m_product").add(Expression.idEq(productId)); So I want to search every order that contains a product. However, with this query it keeps returning 0 orders and I don't really see what I'm doing wrong. Thanks!

  • Why GWT? Advantages and Trade-Offs of Using This RIA Framework

    - by prometheus
    I'm new to stackoverflow and have been reading through a bunch of the "highest voted" questions for GWT. Several of these questions talk about the pitfalls or problems with GWT. In the articles: Which Javascript framework (jQuery vs Dojo vs … )? and Biggest GWT Pitfalls?, some posters seem to suggest that GWT is not lightweight enough or that there are better alternatives that may be used. Do most of you feel that there are problems with GWT that have not been fixed with GWT 2.0 -- which would make you inclined to suggest using a simpler framework for a new project? To some extent, shouldn't GWT be somewhat future-proof (since you don't have to worry about it changing drastically from release to release and since it is backed by Google)? I realize that the answer to this question depends greatly upon what you want to do or what you wish to make. I am looking at this from the perspective of starting a new web application that will eventually be used by millions of users.

  • Unit testing Jade

    - by Strawberry
    Hi, What techniques and design strategies have people used to aid in unit testing Jade applications? In particular, how do people typically go about testing Behaviours - which are tightly coupled to the Agent instance and the Jade environment? I'm aware of the JadeMX project, but this appears to be geared more towards system testing - in particular the message exchange between collaborating agents. Thanks.

  • jsf flash.keep and redirects does not seem to work

    - by user384706
    Hi, I am trying to use JSF 2.0 flash via redirects. I have a class named UserBean (ManagedScoped and RequestScoped). It has a method called getValuesFromFlash which essentially gets the values from the flash and sets the coresponding properties of the UserBean public void getValuesFromFlash() { Flash flash = FacesContext.getCurrentInstance().getExternalContext().getFlash(); firstName= (String) flash.get("firstName"); lastName = (String) flash.get("lastName"); } In the entry page the <h:inputText> are bound to the flash. Snippet follows: Entry.xhtml <h:form> <table> <tr> <td>First Name:</td> <td> <h:inputText id="fname" value="#{flash.firstName}" required="true"/> <h:message for="fname" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:inputText id="lname" value="#{flash.lastName}" required="true"/> <h:message for="lname" /> </td> </tr> </table <p><h:commandButton value="Submit" action="confirmation?faces-redirect=true" /></p> </h:form> In confirmation.xhtml these values are supposed to be displayed but they are not. Snippet follows: <table> <tr> <td>First Name:</td> <td> <h:outputText value="#{flash.keep.firstName}" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:outputText value="#{flash.keep.lastName}"/> </td> </tr> </table> <h:form> <p><h:commandButton value="Confirm" action="finished?faces-redirect=true" /></p> </h:form> In finished.xhtml I want all these to be displayed so: <h:body> <h:form> #{userBean.getValuesFromFlash( )} <table> <tr> <td>First Name:</td> <td> <h:outputText value="#{userBean.firstName}" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:outputText value="#{userBean.lastName}"/> </td> </tr> </table> </h:form> </h:body> Instead when I get redirected to confirmation.xhtml neither first nor last name is displayed, despite I used flash.keep Also in finished.xhtml I get org.apache.el.parser.ParseException: Encountered " "(" "( "" at line 1, column 30. Was expecting one of: "}" ... "." If I remove the parenthesis from the expression #{userBean.getValuesFromFlash( )} and make it = #{userBean.getValuesFromFlash} javax.el.ELException: /done.xhtml: Property 'getValuesFromFlash' not found on type com.UserBean But why no property??It is a method! Why is the method not visible? What I am doing wrong here please? I am using JSF2.0 (MyFaces), Eclipse Helios and Tomcat 6 (Have also tried in Tomcat 7 but no luck). Any help is appreciated. Thanks!

  • Using java2d user space measurements with TextLayout and LineBreakMeasurer

    - by Andrew Wheeler
    I have a java2d image defined in user space (mm) to print an identity card. The transformation to pixels is by using an AffineTransform for the required DPI (Screen or print). I want to wrap text across several lines but the the TextLayout does not respect user space co-ordinates. private void drawParagraph(Graphics2D g2d, Rectangle2D area, String text) { LineBreakMeasurer lineMeasurer; AttributedString string = new AttributedString(text); AttributedCharacterIterator paragraph = string.getIterator(); int paragraphStart = paragraph.getBeginIndex(); int paragraphEnd = paragraph.getEndIndex(); FontRenderContext frc = g2d.getFontRenderContext(); lineMeasurer = new LineBreakMeasurer(paragraph, frc); float breakWidth = (float)area.getWidth(); float drawPosY = (float)area.getY(); float drawPosX = (float)area.getX(); lineMeasurer.setPosition(paragraphStart); while (lineMeasurer.getPosition() < paragraphEnd) { TextLayout layout = lineMeasurer.nextLayout(breakWidth); drawPosY += layout.getAscent(); layout.draw(g2d, drawPosX, drawPosY); drawPosY += layout.getDescent() + layout.getLeading(); } } The above code determines font metrics using user space sizing of the Font and thus turn out rather large. The font size is calculated as best vertical fit for the number of lines in an area with the calculation as below. E.g. attr.put(TextAttribute.SIZE, (geTextArea().getHeight() / noOfLines - LINE_SPACING) ); When using g2d.drawString("Some text to display", x, y); the font size appears correct. Does anyone have a better way of doing text layout in user space co-ords?

  • Knight's tour / recursion

    Hey, I'm trying to learn a little bit more about recursion but somehow I can't solve the knight's tour and I'm hoping someone can point out my logic error. public class main { static int fsize = 5; static int board[][] = new int[fsize][fsize]; static int[] sprung_x = {1,2,2,1,-1,-2,-2,-1}; static int[] sprung_y = {-2,-1,1,2,2,1,-1,-2}; static void SucheWeg(int schrittnummer, int x, int y) { board[x][y] = schrittnummer; if( schrittnummer == ((fsize*fsize)-1)) { for(int i = 0; i<fsize; i++) { for(int c=0; c<fsize; c++) { System.out.printf("%3d", board[i][c]); } System.out.println("\n"); } } else { for(int i = 0; i<8; i++) { for(int c = 0; c<8; c++) { if( (x+sprung_x[i]) >= 0 && (x+sprung_x[i]) < fsize && (y+sprung_y[c]) >= 0 && (y+sprung_y[c]) < fsize ) { if(board[x+sprung_x[i]][y+sprung_y[c]] == -1) { System.out.println("Move: "+schrittnummer + "\n"); SucheWeg(schrittnummer+1, (x+sprung_x[i]), (y+sprung_y[c])); } } } } board[x][y] = -1; } } public static void main(String[] args) { System.out.println("Begin: \n"); for(int i = 0; i<fsize; i++) { for(int c = 0; c<fsize; c++) { board[i][c] = -1; } } SucheWeg(0, 0, 0); System.out.println("\nEnd"); } }

  • InvalidAttributeValueException when using non-ascii characters in JNDI

    - by matdan
    Hi, I have some trouble using JNDI since it accepts only 7-bits encoded parameters. I am trying to change an LDAP entry using JNDI with the following code : Attribute newattr = new BasicAttribute("userpassword", password); ModificationItem[] mods = new ModificationItem[1]; mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, newattr); context.modifyAttributes("uid=anID,ou=People,o=MyOrganisation,c=com", mods); If my password contains only ascii characters, it works perfectly, but if I use a non-ascii character, like "à", I have this error message : javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 19 - The value is not 7-bit clean: à]; My ldap supports those characters so I guess it comes from JNDI. Does anyone know how to fix that? Am I supposed to convert my parameter? How can I do that easily? Thanks

  • Eclipse does not recognize Classes of the jar

    - by Tom Brito
    I've included a new jar in my jre/lib/ext folder, and updated the Eclipse jre so the Eclipse see the new jar in the default JRE System Library. The trouble is that even showing the jar in the JRE System Library, the Eclipse does not see the Classes. And the worst: Eclipse see tha packages! It don't see only the classes! Here is a printscreen showing the jar withing the JRE System Library, and the Eclipse preview showing only the packages: http://picasaweb.google.com/brito.pro/Fail#5458323206632279634 Any idea how to solve this? :?

  • Hibernate mapping - "Could not determine type"

    - by Pool
    I currently have the following objects persisting successfully: Person first name, etc. Exams title, date, etc. I'd like to now create a third table Exam results. For this table I believe it should be person ID, exam ID and result, and this is a many to many relationship. @Entity public class ExamResult { private Exam exam; private Person person; private double value; @Id @ManyToOne( cascade = {CascadeType.PERSIST, CascadeType.MERGE} ) @JoinColumn(name="EXAM_ID") public Exam getExam() { return exam; } public void setExam(Exam exam) { this.exam = exam; } @Id @ManyToOne( cascade = {CascadeType.PERSIST, CascadeType.MERGE} ) @JoinColumn(name="PERSON_ID") public Person getPerson() { return person; } public void setPerson(Person person) { this.person = person; } public double getValue() { return value; } public void setValue(double value) { this.value = value; } } The error: org.hibernate.MappingException: Could not determine type for: Person, at table: ExamResult, for columns: [org.hibernate.mapping.Column(person)] I think I may be going about this the wrong way, but I can't work out how to proceed with this relationship from the tutorial. Any ideas?

  • How to get video file details eg. duration in Android?

    - by spirytus
    I struggle to get specific video file details so duration etc. from the file the files recorded earlier. All I can currently do is to get cursor with all the files, then loop one by one. Cursor cursor = MediaStore.Video.query(getContext().getContentResolver(), MediaStore.Video.Media.EXTERNAL_CONTENT_URI, new String[]{MediaStore.Video.VideoColumns.DURATION,MediaStore.Video.VideoColumns.DATE_TAKEN,MediaStore.Video.VideoColumns.RESOLUTION,MediaStore.Video.VideoColumns.DISPLAY_NAME}); if(cursor.moveToFirst()) while(!cursor.isLast()){ if(cursor.getString(3)==fight.filename) { // do something here } cursor.moveToNext(); } I need however to access details of specific files so I tried to create URI but no luck as cursor returned is always null. Where do I go wrong? Uri uri = Uri.parse(Environment.DIRECTORY_DCIM+"/FightAll_BJJ_Scoring/"+(fight.filename)); Cursor cursor = MediaStore.Video.query(getContext().getContentResolver(), uri, new String[]{MediaStore.Video.VideoColumns.DURATION,MediaStore.Video.VideoColumns.DATE_TAKEN,MediaStore.Video.VideoColumns.RESOLUTION,MediaStore.Video.VideoColumns.DISPLAY_NAME}); // cursor is always null here

  • How can Swing dialogs even work?

    - by Bart van Heukelom
    If you open a dialog in Swing, for example a JFileChooser, it goes somewhat like this pseudocode: swing event thread { create dialog add listener to dialog close event { returnValue = somethingFromDialog } show dialog (wait until it is closed) return returnValue } My question is: how can this possibly work? As you can see the thread waits to return until the dialog is closed. This means the Swing event thread is blocked. Yet, one can interact with the dialog, which AFAIK requires this thread to run. So how does that work?

  • Unmarshalling collections in JaxB

    - by Stas
    Hi, suppose I have this class: public class A { private HashMap<String, B> map; @XmlElement private void setB(ArrayList<B> col) { ... } private ArrayList<B> getB() { ... } } When trying to unmarshall an xml document to this class using JaxB I notice that instead of calling the setB() method and sending me the list of B instances JaxB actually calls the getB() and adds the B instances to the returned list. Why? The reason I want the setter to be called is that the list is actually just a temporary storage from which I want to build the map field, so I thought to do it in the setter. Thanks.

  • How can I specifiy JUnit test dependencies?

    - by Egon Willighagen
    Our toolkit has over 15000 JUnit tests, and many tests are known to fail if some other test fails. For example, if the method X.foo() uses functionality from Y.foo() and YTest.testFoo() fails, then XTest.testFoo() will fail too. Obviously, XTest.testFoo() can also fail because of problems specific to X.foo(). While this is fine and I still want both tests run, it would be nice if one could annotate a test dependency with XTest.testFoo() pointing to YTest.testFoo(). This way, one could immediately see what functionality used by X.foo() is also failing, and what not. Is there such annotation available in JUnit or elsewhere? Something like: public YTests { @Test @DependsOn(method=org.example.tests.YTest#testFoo) public void testFoo() { // Assert.something(); } }
