Printing DVT Components
So, I'm getting together some estimates for using a few dvt: components (pieGraph, horizontalBar graph, etc...) using 11.1.1.3 and was wondering if there is an easy way to make these graphs printable? I know that you can make them printable via firefox 3.6 by setting the imageFormat="PNG" but I would like to continue to use the default flash versions of the graphs if possible since they're the prettiest (yes, I know how shallow of me).
Is there a way to make these graphs printable without having to use the imageFormat="PNG" flag (or without having to add a "print this screen" button?
Thanks in advance,
-Rob
Flash doesn't print - so you'll have to convert them to PNG - if you prefer to have your graphs display in flash then the only option is to add a button to your page that uses the af:showPrintableBehavior tag to make the graph switch to png and print.

How to print the components in scrollpane
hi there,
can anyone tell me how to print the scrollpane components, i mean the headers & the main view of the component. i've a scrollpane with the following code and i want to print the components:
JScrollPane pane = new JScrollPane(aTextPane);
pane.setRowHeaderView(aLineNumberComponent);my requirement is i've a editor & lineno component as textpanes and added to scrollpane & when asked to print it should print the lineno component which resides in scrollpane's row header & the editor textpane which is the main view in the scrollpane. how can i achieve this?
i'd would appreciate any suggestions & codes given.
thanx in advance.After adding/removing components to/from a panel try:
panel.revalidate();
panel.repaint() // sometimes this is also needed, I'm
not sure whyI'm not certain, but I think that panel.revalidate() implicitly calls repaint() only if something actually changed in the layout. If nothing changed, it sees no reason to repaint; hence, if something changed in appearance but not in layout, you have to repaint it yourself.
Or something like that. I'm no expert. ;) -
Printing Swing components doesn't work on all printers? Please Help!
I have a really serious problem. I try to print Swing components with the so called PrintUtilities class. The source code can be found here: http://archive.corewebprogramming.com/Chapter15/printing/PrintUtilities.java).
My Swing components are panels (JPanel) including more panels and/or other components like text fields, text areas, combo boxes, radio buttons, check boxes and so on.
On one of my printers (Kyocera mita FS 1010) it works fine. But on other printers (Panasonic DP-2000, HP Deskjet 890 C) the results are weird: Only the first component (independent of the component depth) is printed (and it is every time the same result!).
I don't know whether this is important or not, but all printers I use are installed as network printers.
I have already searched the forum but couldn't find a similar problem.
Can anyone tell me what the problem is and what I can do to solve it?
Thank you for any response in advance!try this:
package ayto;
import java.awt.*;
import java.awt.print.*;
import javax.swing.JComponent;
public class ComponenteParaImprimir

Problem with DVT components on headless server
JDEV/ADF VERSION: 11.1.1.0.1
TECHNOLOGY: Fusion Web Application, WLS 10.3
Hi,
maybe someone has/has the same problem. I have created a page with
some basic dvt components like pie and bar charts. Everything works fine on my dev machine.
When I deploy the generated EAR on the test env (OEL 5, headless) and try to access the
page (which contains the dvt components) I get the following exception:
"Can't connect to x11 server ...."
and the WLS shuts down!!!!
Has anyone an idea if an x server is mandatory?
Thanks in advance for any hints,
Andreas.Andreas,
I don't have a Linux box to test with at the moment, but it has been a common thing I've dealt with in other environments. Have you tried setting up a VNC server on the Linux box and setting the DISPLAY environment variable to reference that display before starting WLS?

Print 2D components via printer
hi,
Printer is connected to windows machine - samba running on it
Client machines are running with SuSE linux.
Client machine configured the printer via SMB access.
Through this configuration we can print documents from open office and editors.. its running fine
Now we want to print documents via java program. using doc favour we suceesfully done it.
Now we need to print pre printed statements thru java program. So using swing components we positioned it and sent print request from linux .. but it is not printing. When the same program run in a windows machine then it is printing. How this can be eliminated...
Can anybody please help me how can this be resolvedIt appears the product you have is a commerical LaserJet.
I recommend posting in the commercial LaserJet forums.

How do we print multiple components each in a different page?
hello
I would like to print multiple JPanels (lets say an array) each in a different page.
The question I ask is about the following code
printerJob.setPrintable(printTable.getInstance(), pageFormat);
try
if (printerJob.printDialog())
printerJob.print();
}Lets say that we have the following code. How do we modify it?

How can I Print a JPanel including all added Components?
Hello dear saviours,
I have a JPanel object which is responsible for displaying a Graph.
I need to Print the Components of this JPanel as close to what they look like to the user as possible.
I thought about casting the JPanel into an Image of some kind, but couldn't find anything but how to add am Image to a JPanel (God damned search engines :-).
But wait, this gets more interesting!
I need to have control over the scale of the Printed matterial.
I want the option to choose between a single page and dividing the drawing the JPanel displays into Multiple-Pages.
In both cases I need full details of all the data (Nodes, Arcs, Text describing the various Nodes and Arcs names or type, etc.).Keeping the sizes of all these components is also important (that means, I don't want the nodes to be tinny-winny and the Fonts to be twice as large as the nodes and so on...).
Attached is the code of the PrintUtillity class I created as an API for printing the JPanel data:
package ild;
import java.awt.*;
import javax.swing.*;
import java.awt.print.*;
/** A simple utility class that lets you very simply print
* an arbitrary component. Just pass the component to the
* PrintUtilities.printComponent. The component you want to
* print doesn't need a print method and doesn't have to
* implement any interface or do anything special at all.
* <P>
* If you are going to be printing many times, it is marginally more
* efficient to first do the following:
* <PRE>
* PrintUtilities printHelper = new PrintUtilities(theComponent);
* </PRE>
* then later do printHelper.print(). But this is a very tiny

How to print a dialog box with all its components ?
Hi !
I've written an application.It has a dialog box [JDialog] containing following components:
1) 2 JLabels.
1) A JTextField.
3) A JTable with some values.
4) A JProgressBar.
5) A JButton.
6) An animated gif image.
I want to print the dialog box with all its components exactly as the are [ Except the button & animated gif ].
Would anybody please help me?
My Operating System: Windows XPThe article over at http://java.sun.com/developer/technicalArticles/Printing/Java2DPrinting/ has some helpful information on printing Swing components.
It suggests creating a subclass of the JComponent that you want to print, and have it implement Printable interface.
So, something like (note, uncompiled / untested code alert) :
import java.awt.Frame;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.HeadlessException;
import java.awt.print.PageFormat;
import java.awt.print.Printable;
import javax.swing.JDialog;
public class PrintableDialog extends JDialog implements Printable {
* Or whichever constructor you need...
public PrintableDialog(Frame owner, String title, boolean modal) throws HeadlessException {
super(owner, title, modal);
* Implementation of the Printable interface.
public int print(Graphics g, PageFormat pf, int pageIndex) {
if (pageIndex != 0) return NO_SUCH_PAGE;
Graphics2D g2 = (Graphics2D) g;
g2.translate(pf.getImageableX(), pf.getImageableY());
getContentPane().paint(g2);
return PAGE_EXISTS;

Problem Printing Documents - No Doc Flavors Supported
Hello everybody. I've been trying to implement a print feature in my applications and I've had absolutely zero luck. Basically, I'm trying to print the contents of an html file. However, there are no PrintServices that show up on my machine that support DocFlavors text/html, or even text/plain.
I searched all over the Internet, but the only tutorials I found involved printing GUI components. I tried putting everything in a JEditorPane and then printing it, but the table is so large horizontally, it runs off the side, so I don't think that route will work.
I checked IRC, scanned through all of Sun's tutorials and print service API documentation, and even searched around for open source Java word processors so I could check how their print features are implemented, but I can't find anything to help me figure this out. I know there has to be a way, though... or stuff like EIOffice and ThinkFree.com wouldn't be able to work. Can somebody please point me in the right direction?
Here's the current code I have:
//display print dialog
DocFlavor df=new DocFlavor("text/html; charset="+DocFlavor.hostEncoding,"java.io.InputStream");
PrintRequestAttributeSet attributes=new HashPrintRequestAttributeSet();
attributes.add(new javax.print.attribute.standard.JobName("NutraSmart Menu",null));
PrintService[] services=PrintServiceLookup.lookupPrintServices(df,attributes);
PrintService service=null;
if(services.length>0)
service=ServiceUI.printDialog(this.getGraphicsConfiguration(), this.getX()+50, this.getY()+50, services, services[0], null, attributes);
else
JOptionPane.showMessageDialog(getContentPane(),"No print services could be found to print this menu.","Error printing menu",JOptionPane.ERROR_MESSAGE);
nutrasmart.debug(nutrasmart.ERROR,"Could not find any services to print menu");
//print menu
if(service!=null)
try
//create temporary HTML file to print from
File tmpfile=File.createTempFile("nsmenu",".html");
tmpfile.deleteOnExit();
String tmpfilestr=tmpfile.getPath();
export_HTML(tmpfilestr);
FileInputStream tmpfilestream;
try
tmpfilestream=new FileInputStream(tmpfilestr);
catch(FileNotFoundException e)
JOptionPane.showMessageDialog(getContentPane(),"A problem was encountered while preparing the menu to print.","Error printing menu",JOptionPane.ERROR_MESSAGE);
return;
//print document
DocPrintJob pj=service.createPrintJob();
Doc doc=new SimpleDoc(tmpfilestream,df,new HashDocAttributeSet());
pj.print(doc,attributes);
catch(Exception e)
JOptionPane.showMessageDialog(getContentPane(),"There was a problem with printing the menu.","Error printing menu",JOptionPane.ERROR_MESSAGE);
nutrasmart.debug(nutrasmart.ERROR,"Error printing file",e.getMessage());
}Really we have a crazy font management.
We have more than 9000 fonts in the /Library/Fonts
To avoid conficts between the the installed system fonts and the Document font folder, we don't use the document font folder, so that we use always the /Library/Fonts/ fonts installed. Anyway some time ago we also used the Document Font folder and we got the same problem.
I think that your idea about closing the document before the printing process has been finished is very interesting. What I do is :
doc.print(print_preset);
doc.close();
But I don't how can I test if the document is being closed before finishing the printing process.

Oracle/adf/view/rich/model/AsyncFetch Error in DVT
Experts,
We have some DVT components in our application which runs perfectly on integrated local Weblogic Sever. Once we deploy it to a Weblogic Standalone server, we are getttnig the following error while trying to access the DVT graph page. Rest of the application is working properly.
Error : oracle/adf/view/rich/model/AsyncFetch
followed by ADF Faces 60097
Jdev 11.1.1.5 and WLS 10.3.5
thnksSolution : Go to EAR Deployment Profile Properties -> File Groups -> Application Libraries ->Filters and here you have to remove the libraries that are ADF DVT.

I have an example below using a simple gui that has print function in it. The aim of the program is when the user clicks on the print button that they can call p the print and print waht ever is in the text area. I'm not sure if i'm in the right forum now so bear with me.
If any one has any ideas or knows how to fix it theres one error in total on the tool kit, its fairly well commented now so hope fully some one can see the problem is fairly annoying

Hi
I am building a ActiveDataModel for the DVT components. However, I am not sure on how to fire insert/ update events to ADS for DataModel(graphs etc) objects. Could some one point me to documentation / samples that demonstrate this
Specifically
1. I have a DVT based off a java DC.
2. I have a Mgd Bean that implements ActiveDataModelDecorator, this returns the DVT in step1 for getModel() and a custom implementation for ActiveDataModel
3. I want to know how to fire active data events(update/insert/delete) to the DVT using the customactivedatamodel above.
4. How do I find out the row key for my iterator if I use the same DC for a table/tree table
Thanks
RaviThanks all for the response. However,I still cannot find
1. How to properly construct an event using the ADSEventUtil that has a bunch of object[] and string[] parameters and a key path that I am not sure how to derive from a java data control.
2. Also, in my case the DVT is bound to a Java DC. so, would firing an event result is getDataModel call so that it returns the updated model ? -
Problems displaying deserialized components
I'm trying to save the state of some objects which extend JComponent and JLayeredPane, and they don't all redisplay on deserializing, although they seem to be in the containment tree.
Basically, I have a class GamePanel which extends JLayeredPane. Also classes Square and Region both of which extend JComponent and use 2D graphics for painting themselves. It seems to serialize OK (but how does one tell?). But when I deserialize, only the lower level of the GamePanel is painted. However, the higher level is populated.
Does anyone have any idea why they're not displaying? The code is below (TestKiller and its menus are generated by NetBeans - hence the slightly odd code). There are 5 menu items (I've simplified a lot from the original so it's a bit clunky): Add Region (you can only do this once in this version), Save As which serializes to a file, Restore which deserializes from a file, Exit which is obvious and Print which outputs the containment hierarchy of GamePanel to standard output.
If you want to try it out, fire up the program, do a File|Add to add a Region (see the dotted lines) and File|Print to see that there's a Square at level 2 and a Region at level 3. Then File|Save as... to save it. Quit the program.
Fire it up again and do a File|Restore and a File|Print. You'll see from the output that the Square and Region are there with identical parameters to the output before, but the Region hasn't displayed its outline.
The output's below, with java-like comments added to show what I've done:

Please someone tell me what I'm doing wrong. As a serialization newbie it's probably something simple, but no amount of validate() and pack() makes any difference.
The code's below - a bit long I'm afraid but it's difficult to cut it down much more and display the problem. The main class (TestKiller) was generated by NetBeans.

The version on 10.5 was supporting it." This means that it's our bug that we keep using Lucida Grande as fallback font even Apple dropped support Thai script with that font after 10.6. Unfortunately this bug was deferred from current development release (11.2) because of time constraint. If this support is critical for your business, can you open a bug in our public bugbase and ask as many vote as possible? In this way I may be able to convince internal team to fix this bug in next release.
Thank you for your feedback!
