How to create an applet in a jDesktopPane

hello i would like to create an applet (JApplet) in a desktop (JDesktopPane).
i have to put the applet in a JInternalFrame so i can move and resize the window around.
indeed i can have several applets in the JDesktopPane.
it would be more powerfull than viewing it in a web navigator.
more i want to load an applet from its web site from its jar file.
i know that from a html page, you have to tell the navigator where is the jar file with the "archive" tag; the "CODE" tag is the name of the class file not the path to the package like my.package.myclass !
can i put my.package.myclass instead of myclass.class in the "CODE" tag?
here's some snaphot of my softwar kevin_shell to give you some ideas:
http://go.to/kevin-net/SNAP
desktop_panel: the JDesktopPane where i have opened a simple applet.
explorer_panel
it is an open source project.
hope someone answer me, i will give to you my source code.

How to create an applet that shows a pdf as non-editable.

Hi friends,
Does any one know how to create an applet that shows a pdf document (should make that pdf a non-editable one) while clicking a link.Its urgent for me as I have to complete this one tomorrow itself...please help me...
I am able to view the pdf document but that cannot be make a non-editable one.
Can anyone gave me the code for that one....please I am not very much good in Java.

PDF is a proprietary format and Java doesn't support it by default. Are you using a 3rd party tool to create the PDF? If so, you need to review the developer docs to see how to make the document non-editable. Frankly, I don't see why you're using an Applet to view a PDF in the first place. What exactly are you trying to do. I'm confused.

How to create an applet, with many squares inside?

Hey,
I'm having problems creating an applet. Heres the image I need to recreate. The drawing should scale, so that it reaches the full width and
height of the applet.
http://img503.imageshack.us/my.php?image=graphicsafx5.jpg
I created a similar one (the code is below), but don't know how to modify it to create the image in the above link. Do I need a for loop? like for ( int i = 0; i < 10; ++i )
import java.applet.Applet;
import java.awt.*;
public class AprilTest1 extends Applet
 public void paint(Graphics g)
 Graphics2D g2 = (Graphics2D)g;
 int width = getWidth();
 int height = getHeight();
 g2.setColor( Color.black );
 g2.fillRect( 0, 0, width, height);
 int pen_width = width/90 + 1;
 g2.setStroke(new BasicStroke(pen_width));
 g2.setColor( Color.white );
 g2.drawRect( width/4, height/4, width/2, height/2);
}

As CeciNEstPasUnProgrammeur said you do need a loop. You can probably make good use of the % operator inside your loop also.
for(int i=0; i<NUMBER_OF_RECTANGLES; i++){
 if(i % 2 == 0) {
 //draw black rectangle
 } else {
 //draw white rectangle
}Just think about what you need to do:
-Start 1 rectangle at (0,0) and have its width and height as getWidth() and getHeight().
-Pick an increment [this will be the 'width' of each rectangle]
-Now for each rectangle you want to move your x and y points right and down by your increment. Moreover, you want to make your width and height smaller by your increment*2
Essentially what I did is initialize 3 variables to 0 [say x, y, and z]. In your for loop use the % operator in an if-else block. If the loop is on an even number make a white rectangle, if the loop is on an odd number make a black rectangle. Set the x and y position to x+z and y+z respectivley. Set the height and width to getHeight()-(z*2) and getWidth()-(z*2) and then increment z by...lets say 10.
This means on the first loop:
x = 0
y = 0
width = getWidth()
height = getHeight()
Second loop:
x = 10
y = 10
width = getWidth()-20 [10 to compensate for the shift, and 10 for the width]
height = getHeight()-20
Here is what I came up with - hope it helps.
import java.applet.Applet;
import java.awt.*;
public class AprilTest1 extends Applet {
 private int x, y, z = 0;
 public void paint(Graphics g) {
 for(int i=0; i<10; i++){
 if(i%2==1){
 g.setColor( Color.white );
 g.fillRect(x+z, y+z, getWidth()-(z*2), getHeight()-(z*2));
 } else {
 g.setColor( Color.black );
 g.fillRect(x+z, y+z, getWidth()-(z*2), getHeight()-(z*2));
 z += 10;
}Any questions, feel free to ask :)

What is lightweight and heavyweight ? how to create my applet lightweight?

Sir ,
t have created an applet and in that i have not use any component
for drawing now i want to use component for applet but cant grtting how to do this , by reference of sun java i have found this code for application to create lightweight::

* A canvas which renders a smiley-face to the screen
* Note: Canvas is a heavyweight superclass, which makes
* SmileyCanvas also heavyweight. To convert this class to

this code is not for applet so how to make this code for applet ?

I use the Snippets folder to store re-usable code. Scroll to
the file or
folder desired, double click and voila! Code is inserted into
the page.
As for the other bells & whistles, you are probably
thinking about DW
Extensions (.mxp) files. There are many 3rd party makers of
extensions.
Some are free, some cost a nominal fee. Check around to see

How to create an applet within an application?

Hi. Im trying to make an applet work within a main application but I cant get it to work because then I have 2 of these and it gives me an error:
public class java_tester extends JFrame implements MouseListener //MAIN APPLICATION
public class MusicPlay extends JApplet //APPLET
I cant have both if them because it is like two different programs.
Can anyone help me with this?
Thanks

ProGenius wrote:
But when I put public class MusicPlay extends JApplet it underlines it because the name of the main program is different and when I give it the same name it still underlines it. I know it probably is easy to do it but I really dont know how to make it work.
Thanks a lot for your helpWhat is "it", what is "it" underlining, and why is this a problem? There's no such concept as "main program". If you're confused by the presence of two whole classes, don't be. Anything beyond the laughably trivial will consist of several classes.

How to create a frame in a applet?

Dear All,
How to create a frame in a applet?
Thanks in advance
Kityy

You can't add a Frame/JFrame to an Applet/JApplet.
An Applet/JApplet has its origins in the class Panel/JPanel.
So, if you make your Applet to an application you
can easily do that by putting your Applet "above" a Frame.
Maybe you can archieve your goals with some Panels?!

HOW TO: Create a GUI "Hello World"


This document describes how to create and run a very simple "Hello World"
Java GUI app using JDeveloper. The application will have one button and one
text field. Clicking the button will populate the text field with the message,
"Hello World!"
Creating The New Application
In this section, we will create an application with an empty frame.
<ol>
[*]Choose File | New Workspace.
</li>
[*]Choose File | Save Workspace.
</li>
[*]Enter <TT>HelloGui.jws</tt> as the name for the workspace.
This creates a Workspace called HelloGui. A workspace organizes all the projects
you need to work on at one time.
</li>
[*]Choose File | New Project.
The Project Wizard opens. This wizard will help you create a new project called
HelloGui. A project contains all the files that go together in one "tier"--for
example, all the files belonging to a single Java Application client, or all
the files belonging to an Enterprise Java Bean. Because we are working on
a simple, one-tier application, we will only need one project in our workspace.
</li>
[*]If the Welcome page appears, click Next.
</li>
[*]On the Project Type page, in the What is the Project's Filename?
field, change the filename to <TT>HelloGui.jpr</tt>. Leave the rest of the
path the same.
</li>
[*]Select A Project containing a new... and choose Application
from the dropdown list.
</li>
[*]Click Next.
</li>
[*]On the Project Options page, in the What is the name of the project's
default package field, enter <TT>helloGui</tt>.
</li>
[*]Click Next.
</li>
[*]On the Project Information page, you can enter any information about your
project that you wish.
</li>
[*]Click Finish.
The Application Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloApp</tt>.
</li>
[*]Select the New Empty Frame radio button.
</li>
[*]Click OK.
The Frame Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloFrame</tt>.
</li>
[*]Click OK.
JDeveloper creates an application, <TT>HelloApp</tt>, containing an empty
frame, <TT>HelloFrame</tt>. The source code for these classes appears in the
Navigator, which is the upper left-hand pane in the JDeveloper IDE.
</li>
[*]Choose File | Save All.</li>
</ol>
Adding a Panel to the Frame
In this section, we will now add a panel to the frame. In the next section,
we will add all the other components to this panel.
<ol>
[*]In the Navigator, double-click <TT>HelloFrame.java</tt>.
A viewer opens. This viewer has four tabs at the bottom:
<ul>
[*]Source, the currently active tab, which displays the source code
of the selected class</li>
[*]Design, which invokes a visual layout designer</li>
[*]Class, which invokes an editor for the class' attributes, and
can help you stay JavaBean complient</li>
[*]Doc, which displays the class' JavaDoc
</li>
</ul>
</li>
[*]Click the Design tab.
The viewer now displays a grey square, a graphical mock-up of your frame.
Also, on the right-hand side of your screen, the Property Inspector opens.
This allows you to quickly set attributes and define events for components.
</li>
[*]In the component palette (the tabbed toolbar near the top of your screen),
select the Swing Containers tab.
</li>
[*]Click the blue square (described in rollover text as <TT>JPanel</tt>) and
click on your frame to add the panel.
The Property Inspector now displays attributes of the JPanel.
</li>
[*]In the Property Inspector, click twice inside the box beside the name
field.
</li>
[*]Change the name to mainPanel.
</li>
[*]Click the box beside the layout field.
</li>
[*]Choose XYLayout.
XYLayout is an easy-to-use Layout for prototyping. Later, we will change the
layout to a more portable one.</li>
</ol>
Adding Components to the Panel
In this section, we finish laying out a prototype UI. We will add polish and
portability to the UI later.
<ol>
[*]In the Component Palette, select the Swing tab.
</li>
[*]Select the <TT>JTextField</tt> component, which looks like a text field
with a cursor.
</li>
[*]In your panel, click and drag the cursor to outline the text field.
Don't worry if the text field doesn't have exactly the right size or position.
We will adjust these later.
The Property Inspector now displays attributes of the JTextField.
</li>
[*]In the Property Inspector, change the name (just as you did for the
JPanel) to <TT>displayField</tt>.
</li>
[*]Change the text to nothing (erase the value that is already there).
</li>
[*]In the Component Palette, select the <TT>JButton</tt> component, which looks
like a button being clicked.
</li>
[*]In your panel, click and drag the cursor to outline the button.
The Property Inspector now displays attributes of the JButton.
</li>
[*]In the Property Inspector, change the name and action command
to helloButton.
</li>
[*]Change the text to <TT>Say Hello!</tt>.
</li>
[*]Choose File | Save All.</li>
</ol>
Wiring Up the UI
In this section, we wire the UI so that clicking the button causes "Hello
World!" to display in the text field.
<ol>
[*]In the Property Inspector, select the Events tab.
</li>
[*]Click the box next to the Action Performed field and press the Enter
key.
This creates a method, <TT>helloButton_actionPerformed()</tt>, which will
be invoked when the button is clicked, and displays the source code for the
method stub in the viewer.
</li>
[*]In the viewer, add the following command to the body of the method:
<TT>displayField.setText("Hello World!");</tt>
</li>
[*]Choose File | Save All.</li>
</ol>
Testing the Prototype Application
<ol>
[*]Choose Run | Run "HelloApp".
Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field.
</li>
[*]Close your application.</li>
</ol>
Refining the UI
In this section, we polish the UI so that the components have the right size
and alignment, the text in the text field shows up red, and the panel uses the
portable GridBag layout instead of the JDeveloper-specific XYLayout.
<ol>
[*]In the viewer, select the Design tab.
</li>
[*]Select your text field.
</li>
[*]Drag the edges of your text field until it is the size you want.
</li>
[*]Drag the center of the text field until it is the vertical position you
want.
</li>
[*]Right-click the text field and choose Align Center.
This centers your text field horizontally in the frame.
</li>
[*]In the property inspector, click the box next to the foreground field.
</li>
[*]Click the ellipses (...).
A color editor appears.
</li>
[*]Select Red from the dropdown list.
</li>
[*]Click OK.
</li>
[*]On your frame, select your button.
</li>
[*]Drag the right edge of your button until it is the horizontal size you want.
</li>
[*]Select your text field, and multi-select your button by control-clicking
it.
</li>
[*]Right-click your button or text field.
</li>
[*]Choose Same Size Vertical.
This sets the height of all selected components to that of the first selected
component (the text field).
</li>
[*]Right-click your button or text field.
</li>
[*]Choose Align Center.
This aligns the center of all selected components to that of the first selected
component (the text field).
</li>
[*]Select your panel by clicking anywhere on the grey background in the visual
designer.
</li>
[*]In the Property Inspector, click the box beside the layout field.
</li>
[*]Select GridBagLayout from the dropdown list.
</li>
[*]Choose File | Save All.</li>
</ol>
Running the Finished Application From Within JDeveloper
<ol>
[*]Choose Run | Run "HelloApp".
Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field, in red.
</li>
[*]Close your application.</li>
</ol>
Deploying the Application to Your File System
<ol>
[*] In the Navigator, right-click <tt>HelloGui.jpr</tt> and choose New Deployment
Profile.
The Deployment Profile Wizard opens.
</li>
[*]If the Welcome page appears, click Next.
</li>
[*]On the Delivery page, select Web Application or Command-Line Application
from the dropdown list, and click Next.
</li>
[*]On the Staging Area page, in the Deployment Destination field, enter
<tt><JDeveloper>/HelloGui</tt>, where <tt><JDeveloper></tt>
is your JDeveloper root directory. Click Next.
</li>
[*]On the Project page, select all the <tt>.java</tt> files and click Next.
</li>
[*]Skip the Archive page and Applet Tags page by clicking Next on each.
</li>
[*]On the Libraries page, shuttle all libraries from the Project Libraries
list to the Deployed Libraries list, and click Next.
</li>
[*]On the Finish page, name the profile <tt>HelloGui.prf</tt>, and click Finish.
</li>
[*]When JDeveloper asks you if you want to deploy now, click Yes.</li>
</ol>
JDeveloper will archive your application files and copy this archive and all
other required libraries to <tt><JDeveloper>/HelloGui</tt>.
Running the Application from the Command Line
<ol>
[*]Open a command-line prompt.
</li>
[*]Enter the following script.
Note: You may want to create a batch file containing this script. Be
sure to replace JDeveloper_Home with your JDeveloper home directory.
<pre>set __CLASSPATH_ROOT_DIR__=JDeveloper_Home\HelloGui
set CLASSPATH="%__CLASSPATH_ROOT_DIR__%\HelloGui.jar"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\xmlparserv2.jar"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\classes12.zip"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\jdev-rt.zip"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\swingall.jar"
cd JDeveloper_Home\HelloGui
jre -cp %CLASSPATH% helloGui.HelloApp</pre>
</li>
[*]Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field, in red.
</li>
[*]Close your application.</li>
</ol>

HELP!!! How to create a modal JPanel

Hi
I've been creating an applet that uses transparent JPanels to draw boxes that look like windows.
I'm in need, now, to create one that asks for user input (ie "click the OK button") and that blocks the current thread and other panels until the user has answered.
It's totally similar to a windows message box.
How do i do it????
I've been taking examples from this tech tip (http://java.sun.com/developer/JDCTechTips/2001/tt1220.html) that explains almost everything (but uses JInternalFrame), and also 2 ways of doing the thread-blocking work:
One way uses a worker thread to compose the UI and wait() while the java dispatcher thread does the app events (action, paint) and notifyAll() when the user presses "OK".
In the other way, the author copied the code from EventQueue's dispatchEvent() and created a dispatcher thread into the modal JFrame, so that events could be processed without having to use another thread.
I think this last method is a hack because of portabilityu issues, for example code in my dispatchEvent() (JRE1.6.0) contains more checks and cases than the code he postet in that page.
I think I would have problem running similar code on a previous or future version of the JRE.
Anyway I haven't succeeded yet to wake up the waiting thread when the user has clicked OK. The notifyAll method executes, no exception is thrown, but the other thread remains asleep.
Here's my code (note the "synchronized" keywords)
synchronized public int show(String title, String message, int buttons, boolean isError) {
        if (isError)
            jptBox = new TLPanel(title, new Color(104,10,11), new Color(234,30,34), new Color(241,79,83));
        else
            jptBox = new TLPanel(title, new Color(6,29,108), new Color(80,103,184), new Color(120,138,200));
        jptBox.setBounds(TLStartup.centerSize(400, 100));
        btn1 = new JButton("OK");
        btn1.setBounds(180, 75, 40, 20);
        btn1.addActionListener(new ActionListener() {
            public synchronized void actionPerformed(ActionEvent e) {
                this.notify();
        jptBox.add(btn1);
        cnt.add(jptBox);
        cnt.setComponentZOrder(jptBox, 0);
        try {
            this.wait();
        } catch (Exception ex) {
            System.out.println(ex.toString());
        return MB_ANSWER_YES;
    }

I put a boolean variable test=true into my class, and modified the code to check it into the waiting cycle:
        try {
            while (test)
                this.wait(1000);
        } catch (Exception ex) {
            System.out.println(ex.toString());
        }and to reset it into the actionPerformed:
        btn1.addActionListener(new ActionListener() {
            public synchronized void actionPerformed(ActionEvent e) {
                test = false;
                this.notifyAll();
        });And HOW COME it does work now ??? (with some delay)

Hi Gurprit,
A null value is being passed at runtime. Make sure that you enter values when filling in the form.
Also check for the cardinality of the nodes being used. You can also initiliaze your value attributes as follows:
In wdDoInit() method:
wdContext.currentNodeAElement.setValueA("");
Context is as follows:
RootNode
|____NodeA
        |_____ValueA
Hope it helps.

 }catch(Exception e) { e.printStackTrace(); }
 return frame;

If you are using MSSQL SERVER then try creating a stored procedure like this
create proc Name
select * from Table
by executing this in sql query analyzer will create a stored procedure that returns all the data from Table
here is the syntax to create SP
Syntax
CREATE PROC [ EDURE ] procedure_name [ ; number ]
 [ { @parameter data_type }
 [ VARYING ] [ = default ] [ OUTPUT ]
 ] [ ,...n ]
[ WITH
 { RECOMPILE | ENCRYPTION | RECOMPILE , ENCRYPTION } ]
[ FOR REPLICATION ]
AS sql_statement [ ...n ]
Now Create new report and create new connection to your database and select stored procedure and add it to the report that shows all the columns and you can place the required fields in the report and refresh the report.
