Problem in java.awt.print

Hi here is my code .
I am generating page dynamically and passing to printer.
Printing Functionalities working file. But I am taking some data from database (Access). And in this code for example i have 4 records in Database and i am generating 4 pages (each page for resord).
I am getting only 2 records. And for other two records i am getting blank page.
Reason is My ResultSet object is moving to next record twice.
I mean if i have 6 records i get only 3 pages.
If i have 10 records i get only 5 pages and If i have 1 record i dont get any page.
How shall i solve this problem.
Thanx in advance.

  • Problem with Java Print API ( awt ) : Migrated from 1.1 to 1.4

    We had migrated an application ( applet based) from Java 1.1.8 to java 1.4.
    We use the java.awt.print apis for printing data from our applications.
    There is difference in print quality after the migration. For e.g. if the data frame had a scroll bar when taken print out, the scroll bar was not visible in java1.1 version application but is being printed with java1.4 version.
    We are unable to find the cause of this problem. Any help in this regard would be of great help.

  • Problem with too small page size using Java 2D Printing API.

    Hello,
    I have problem with resolution of printer using Java 2D Printing API. Despite my printer has 600 x 600 DPI, inside java.awt.print.Printable.print(Graphics, PageFormat, int) I receive page format with 600 x 840 page size.
    I have tried to set resolution using javax.print.attribute.PrintRequestAttributeSetand javax.print.attribute.standard.PrinterResolution, but with no result.
    Can anybody solve this problem?
    Regards,
    Karl.

    600 x 840 is a Point value; Point is defined as 1/72nd of an inch. Printers do have much higher DPI than this, but I believe that this DPI has to do with richness of the printed image, not an actual ability to color with that level of resolution. You might want to try calling zoom on your Graphics2D object. Otherwise, I don't know what else you can try.

  • Problem with PageFormat when printing

    Hi.
    I use the following class to print large JPanels, but I have a problem with the PageFormat. For example:
    I want to print a JPanel called labelPanel, so I write "PrintUtilities.printComponent(labelPanel);". It will now print this Panel on multible Pages, so I can put them together to see the whole Panel. This works fine, BUT I can't change the PageFormat. When the printDialog pops up I can choose a printer (this works), but if I change the page format (for example from "letter" to a bigger size) the PageFormat object stays the same as always, some kind of defaultFormat I think.
    pf.getImageableWidth() always has the same value and I dunno why that doesn't work. Everything works, except changing the format of the page...

  • Problem in setting the printer

    Hi,
    I am new to swings and am trying to print my table using PrintJob class. In this I will get the printer name. So I have to set that as a printer to do the job.
    I am able to print by selecting the printer in printDialog but I want to give my printer and I dont want that printDialog box. Plz tell me solution.
    As from the docs, i came to know that if we remove printdialog(), it wont show you the dialog box, but its talking the default one, my case is it should take the user input.
    Here is my code and working fine.
    public void print(String printer){
    // In this I have to set printer as the printer to do the job by suppresing the print dialog.
    PrinterJob pj = PrinterJob.getPrinterJob();
    PageFormat pf = pj.defaultPage();
    pj.setPrintable(this, pf);
    if (pj.printDialog()) {
    try {
         pj.print();
    } catch (Exception e) {

  • Problems changing colour using Graphics class in java.awt

    Hi,
    The problem only happens when more than two images are on a panel. In this case, I have to strings that are drawn. The first drawn string is called "A" the second drawn string is called "B". However, when i change the colour of "B" to let's say Red, the panel erases the letter "B" and insteads changes "A" to red. How can I fix this so that when the user chooses the colour red it changes the colour of the latest drawn string and not the first one. please help!!!!
    import java.awt.*;
    public class StringPanel extends GBPanel
         private String shape = "clear", str;
         private int x, y;
         private Color color = Color.black;
         public void paintComponent(Graphics g)
              super.paintComponent(g);
              g.setColor (color);
              if(shape.equalsIgnoreCase("draw string"))
                   g.setColor(color);
                   g.drawString(str, x, y);
              else if (shape.equalsIgnoreCase("exit"))
                   System.exit(0);
         public void drawCurve(Color color)
         this.color = color;
         repaint();
         public void drawString(String shape, String str, int x, int y)
              this.shape = shape;
              this.str = str;
              this.x = x;
              this.y = y;
              repaint();
         public void drawString1(String shape, String str, int x, int y)
              Graphics g = getGraphics();
              g.setColor(color);
              if (shape.equalsIgnoreCase("draw string"))
                   g.setColor(color);
                   g.drawString(str, x, y);
              else
                   repaint();
    }

    well, as I said, I can't remember what the update method thing was for... I think it was related to not clearing the screen first.
    Anyway, if you maintain a list of objects that should be drawn and then in the paintComponent method, loop thru the list of objects and redraw them, it will work. Then you change the state of an object and call repaint. When you are going to change color, you need to, in effect, redraw the entire affected area. Now this can be done partially with clipping, but it's complicated to deal with that. So the simplest way is just redraw everything on repaint.

  • Problem with Horizontal Scroll on java.awt.List

    I use the same code for a General Application as a CDC Application.
    I have no problem at all with the General Application but on the CDC I can't scroll to the right (horizontal).
    Why do I get this problem on the CDC application and not on a regular application?
    I use the PP-1.0 Profile for the CDC application. Does it not support horizontal scroll on java.awt.List?
    This is the code:

  • OutOfMemory error in java.awt.image.DataBufferInt. init

    We have an applet application that performs Print Preview of the images in the canvas. The images are like a network of entities (it has pictures of the entities involve (let's say Person) and how it links to other entities). We are using IE to launch the applet.
    We set min heap space to 128MB, JVM max heap space to 256MB, java plugin max heap space to 256MB using the Control Panel > Java.
    When the canvas width is about 54860 and height is 1644 and perform Print Preview, it thows an OutOfMemoryError in java.awt.image.DataBufferInt.<int>, hence, the Print Preview page is not shown. The complete stack trace (and logs) is as follows:
    Width: 54860 H: 1644
    Max heap: 254 # using Runtime.getRuntime().maxMemory()
    javaplugin.maxHeapSize: 256M # using System.getProperties("javaplugin.maxHeapSize")

    Drilling down the cause of the problem. The OutOfMemory occurred in the constructor of DataBufferInt when it tried to create an int array:
    public DataBufferInt(int size) {
    super(STABLE, TYPE_INT, size);
    data = new int[size]; # this part produce out of memory error when size = width X height
    bankdata = new int[1][];
    bankdata[0] = data;
    The OutOfMemory error occurred when size is width * height (54860 X 1644) which is 90,189,840 bytes (~86MB).
    I can replicate the OutOfMemory error when initiating an int array using a test class when it uses the default max heap space but if I increase the heap space to 256MB, it cannot be replicated in the test class.
    Using a smaller width and height with product not exceeding 64MB, the applet can perform Print Preview successfully.
    Given this, I think the java applet is not using the value assigned in javaplugin.maxHeapSize to set the max heap space, hence, it still uses the default max heap size and throws OutOfMemory in int array when size exceeds the default max heap space which is 64MB.
    For additional information, below is some of the java properties (when press S in java applet console):
    browser = sun.plugin
    browser.vendor = Sun Microsystems, Inc.
    browser.version = 1.1
    java.awt.graphicsenv = sun.awt.Win32GraphicsEnvironment
    java.awt.printerjob = sun.awt.windows.WPrinterJob
    java.class.path = C:\PROGRA~1\Java\jre6\classes
    java.class.version = 50.0
    java.class.version.applet = true
    java.runtime.name = Java(TM) SE Runtime Environment
    java.runtime.version = 1.6.0_17-b04
    java.specification.version = 1.6
    java.vendor.applet = true
    java.version = 1.6.0_17
    java.version.applet = true
    javaplugin.maxHeapSpace = 256M
    javaplugin.nodotversion = 160_17
    javaplugin.version = 1.6.0_17
    javaplugin.vm.options = -Xms128M -Djavaplugin.maxHeapSpace=256M -Xmx256m -Xms128M
    javawebstart.version = javaws-1.6.0_17
    Kindly advise if this is a bug in JRE or wrong setting. If wrong setting, please advise on the proper way to set the heap space to prevent OutOfMemory in initializing int array.
    Thanks a lot.

  • Problem Launching Java Applet with Plug-in: Version 1.4.2_01

    Hello out there:
    I recently installed j2re-1.4.2_01 on my home computer but have been unable to access Web sites emmploying JAva applets. The following is an email exchange with Jeff Hall of Lowell Observatory, manager of an educational site hosted by Lowell, trying to resolve my problem. The messages are better understood if read in reverse order.
    I'm hoping that someone will recognize the source of my problem and can recommmend a solution. I would appreciate any help offered.
    Thanks,
    Mike Coucke
    Hi Jeff:
    Well, I guess the problem lies with me somewhere. Here's my answer/status to your questions/suggestions:
    1) I'm using MS Windows Me version 4.90.3000
    2) I do have the directory C:\Windows\.jpi_cache\jar\, but the only thing in it is an empty folder labeled "1.0". The file LP.jar does not exist anywhere on my hard drive.
    3) I tried several game sites that utilized Java applets and got the same results: the Java cup in the upper left corner followed a few seconds later by the red "X". So, evidently the problem is somewhere on my end.
    I'm going to post our email exchanges in a Java Users Forum managed by Sun to see if anyone out there can solve my problem. However, if you have any more suggestions, I'll be glad to try them.
    Thanks for the help.

    Mike,
    Rats! What version of Windows are you using? It's a little strange to
    see the user directory set to C:\Windows; if you're using XP, I'd expect
    it to be something like C:\Documents and Settings\Mike Coucke. In any
    event, the output that is of concern is these two lines:
    java.lang.ClassNotFoundException: LPRemote.class
    Caused by: java.net.UnknownHostException: proxy
    It looks like your browser is not finding our server's IP when it comes
    time to download the necessary Java code.
    LPRemote.class is the fundamental code that runs LOPARC, and your
    browser should be downloading it automatically when you click connect.
    LPRemote.class is stored along with a bunch of other classes in a file
    called "LP.jar" that you download from our server. So, if you go to C:
    in Windows Explorer and do a file search for LP.jar, you should find it.
    On my machine, it's stored in a directory called ".jpi_cache\jar\" in my
    user home directory. Let me know if you have this file, or the
    jpi-cache directory.
    One other thing you might try is going to a different site that you know
    uses Java applets -- I think some of the online game rooms at Yahoo use
    Java. See if other sites that use Java load correctly. Then we'll know
    if it's our server specifically, or a more general problem on your end.

    Hello Jeff:
    I still have the Java "blues". I followed your instructions, but am still unable to launch a LOPARC session. After an initial failure, I uninstalled all three Java versions I had (1.4.0, 1.4.1, 1.4.2), then reinstalled 1.4.2_01 from the Sun website.
    Now, when I try to launch LOPARC, I initially get a blank window with the Java cup in the upper left corner. After about 20 seconds, the cup changes to a red "X". During those 20 seconds, the following appear in the IE message bar at the bottom of the window: "Applet LPRemote notinited" (their spelling) which changes to "Loading Java Applet Failed..." when the red "X" appears.
    Following is a copy of the log from my Java Console during all of this:

    Hi Mike,
    Try it now. I think this problem has arisen because Sun just
    released a new version of the Plug-in (1.4.2), and when we released the
    public beta of LOPARC, only one relevant version (1.4.0) was available
    and the LOPARC code was written to look for that by default. I have
    just recoded the relevant routines so they should now cause your browser
    to simply pick up the latest 1.4 version of the Plug-in you have
    installed, whatever it is. I "broke" Java on my machine to replicate
    your problem, and the code I inserted today did fix it. Hopefully it
    will have the same effect for you. I am running IE 6 and plugin
    1.4.2_01 (as accessed via Tools->Sun Java Console).
    One broader problem: some (non-LOPARC-specific) users on the Sun
    forums have reported the "JRE collision" you are seeing when multiple
    versions of the Plug-in are installed on the same machine. So if the
    fix I made to our code doesn't work, one option would be to uninstall
    all Java components from your computer and do a fresh install of the
    latest runtime environment.
    Let me know how/if this works. Thanks for the feedback and for your
    patience.
    Best regards,
    Jeff Hall

    Hello Jeff:
    So far, I have been unable to launch a LOPARC session. I repeatedly
    get the following error message:
    "Exception: java.lang.ClassNotFoundException: LPRemote.class"
    My browser is MS Internet Explorer version 6.0.2800.1106 Initially I was
    using Java Plug-In version 1.4.1 and received the error message. I went
    to the Sun website and downloaded/installed Java Plug-In version 1.4.2
    and still get the message.
    Before I try to launch LOPARC, I can select Tools->Sun Java Console from
    IE's pull down menu to check my Java Plug-In version. When I try to
    launch LOPARC, I get the following message:
    "Applet(s) in this HTML page requires a version of Java different from
    the one the browser is currently using. In order to run the applet(s)
    in this HTML page, a new browser session is required, press 'Yes' to
    start a new browser session." If I select 'No', I get the following
    message: "Java Plug-in detected JRE collission"
    If I select 'Yes', a new browser window opens and then I get the first
    message above.
    Can you help?

    Dear Michael Coucke:
    Thank you for registering with Lowell Observatory's online education
    site. We hope you enjoy using it and visit regularly as we continue to
    expand its features and capabilities. This is a one-time welcoming
    email.
    For your records, your user ID is xxxxx, and your password is #########.
    You'll need to supply these each time you log in.
    This site gives you access to research-grade equipment including a 16"
    telescope, CCD detector, and image processing software. Our online
    archive of data is now available 24/7. The telescope will be opening to
    our onsite users in May, and on select nights to the Internet at large
    in June.
    We have designed this site so you don't need a huge monitor or a
    supercomputer to use it. All pages are viewable on screens running at
    800x600 resolution or higher. To use LOPARC, you'll need a Java-enabled
    browser with the Java 1.4 plug-in installed. If you don't have the
    plug-in, you'll be prompted to download it the first time you attempt to
    connect. This is an admittedly large (9 MB) but one-time-only download.
    This site works correctly under Internet Explorer version 5 or higher.
    If you use Netscape, you must be running version 6 or higher, and
    display or applet behavior anomalies may occur.
    If at any time you can't connect to our server, simply try again later.
    We do experience several power outages each year, particularly during
    Flagstaff's summer thunderstorm season. Our server is fully protected
    and backed up, and can be quickly brought back on line, but any active
    user sessions will be lost. Thanks for your patience during these
    inevitable downtimes.
    Your questions, comments, suggestions, and bug reports about this site
    are always welcome. On behalf of the LOPARC development team, thanks
    for signing up!

    Hi Mike,
    I see this in your logs:
    Java(TM) Plug-in: Version 1.4.2_01
    Using JRE version 1.4.2_01 Java HotSpot(TM) Client VM
    User home directory = C:\WINDOWS
    Proxy Configuration: Manual Configuration
    Proxy: http=proxy,https=proxy,ftp=proxy,gopher=proxy
    Proxy Overrides:
    I just helped my Dad set up his computer with a new
    cable modem, and had the situation where we couldn't
    access any secure Web sites. The cable folks had us
    disable the proxy. It looks like the error message is
    saying it can't find your proxy server, and the logs
    you posted say that you've decided to configure your
    proxy manually, rather than using the settings from
    IE (which is how mine is set up in the plugin
    control panel.)
    Could that be the problem?

  • JTable displays string in wrong order : my code problem or Java problem ?

    I have the following code that displays data in a JTable, most of the time it works fine, but I've realized when I have a cell with values like : "Snowboarding"+"[123456789]"
    It would display it as : [Snowboarding[123456789
    For a string like : "Chasing toddlers"+"<123456789>"
    It would display it as : <Chasing toddlers<123456789
    It not only moved the last bracket to the front, but also changed its direction from "]" to "[" and from ">" to "<"
    Is there anything wrong with my code ? Or is this a Java problem ?

    * TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
    * or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
    * model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
    * have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
    * with the rows in a different order.
    * <p/>
    * TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
    * are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
    * If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
    * rows the next time a value is requested.
    * <p/>
    * When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
    * header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
    * that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
    * <ul>
    * <li>
    * Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
    * values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
    * <li>
    * SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
    * three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
    * <li>
    * CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
    * that are already sorting - giving a way to initiate a compound sort.
    * </ul>
    * <p/>
    * This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

    * TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
    * or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
    * model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
    * have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
    * with the rows in a different order.
    * <p/>
    * TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
    * are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
    * If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
    * rows the next time a value is requested.
    * <p/>
    * When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
    * header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
    * that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
    * <ul>
    * <li>
    * Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
    * values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
    * <li>
    * SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
    * three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
    * <li>
    * CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
    * that are already sorting - giving a way to initiate a compound sort.
    * </ul>
    * <p/>
    * This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

  • The method add() in java.awt.Container made me in confuse

    Here is my two java code file:

         private static int counter = 0;
         public MyContainer() {

              myButton[1] = new MyButton(5, 40, 200, 30);
              for (int i = 0; i < myButton.length; i++) {
                   add(myButton);
         public void paint(Graphics g) {
              for (int i = 0; i < myButton.length; i++) {
                   System.out.println("MyButton : " + (i+1));
                   myButton[i].draw(g);
         public static void main(String[] args) {
              MyContainer container = new MyContainer();
              JFrame f = new JFrame();
              f.getContentPane().add(container);
              f.pack();
              f.setSize(new Dimension(300, 200));
              f.show();
    //MyButton.java
    package sam.gui;
    import java.awt.Color;
    import java.awt.Component;
    import java.awt.Graphics;
    import java.awt.Graphics2D;
    public class MyButton extends Component {
         private Color m_rectColor = new Color(128, 73, 0);
         public MyButton(int x, int y, int width, int height) {
              setBounds(x, y, width, height);     
         public void draw(Graphics g) {
              Graphics2D g2 = (Graphics2D)g;
              g.setColor(m_rectColor);
              g.fillRect(0, 0,
                        getBounds().width, getBounds().height);

              System.out.println("width = " + getBounds().width);
              System.out.println("height = " + getBounds().height);          
    I thinked the runned result should be below:
    MyButton : 1
    x = 5
    y = 5
    width = 200
    height = 30
    MyButton : 2
    x = 5
    y = 40
    width = 200
    height = 30But in fact, its result is here:
    MyButton : 1
    x = 5
    y = 5
    width = 200
    height = 30
    MyButton : 2
    x = 0
    y = 0
    width = 292
    height = 173I don't know why the result would like this? I have used add(...) method to add two component MyButton to the container MyContainer, But the bounds of the second component is not I want.
    So this problem made me go into confuse.
