JBuilder code...

Hello everybody,
I've written a program in JBuilder wich can store encrypted passwords in a textfile. It works fine when using the 'run project' function in JBuilder, but when i try to compile or run it in the std DOS jdk I'm getting the error: 'NoClassDefFound'. This is propably thanks to some JBuilder specific classes.
Since i'm not plannning on rewriting my whole program, is there anyway to make my JBuilder code exportable???
I'm very desperate so please help,
Jasper

the class that it can't find may be something that you have imported for your program. your classpath needs to tell java where to find any classes you are using, as well as those you have written, in order for it to run.
try using the same classpath that JBuilder uses. when you run your project in JBuilder, the message pane at the bottom should say something like:
C:\JBldr\bin\javaw -classpath "c:\blah\wibble.jar;c:\foo\bar.jar ... "
that classpath must be working if you can run from within JBuilder, so you could try copying the whole classpath string and using it in your javac/java calls from the DOS window. in theory that should work - let us know if you have any success

JTable Column Headers are Squashed!

Hi there,
I'm using JBuilder, and have created a simple enough JTable that I place inside a JScrollPane. I am using my own implementation of the AbstractTable model.
When I run the code, the Column headers are only about 5 pixels high! I have hunted around the JBuilder code (which if you have used JBuilder you will know is extensive!), but it doesn't seem to be doing anything extraordinary.
So has anyone else had this problem? If so, what did you do to rectify.
Yours hopefully
Richard

Hello there, my abstract implementation looks a little like this:
public static final String columns[] = { "", "Request Id", "Date", "Component Name", "Version", "Type" };
public String getColumnName(int columnIndex) {
    return columns[columnIndex];
public Class getColumnClass(int columnIndex) {
    if (columnIndex == 0) {
      return Boolean.class;
    } else if (columnIndex == 1) {
      return Integer.class;
    } else {
      return String.class;
}Thanks

Applet loading as seperate window

Hi,
I'm porting jEdit's help system into an applet form. Its complete, except for an annoyance - it loads as a seperate window, leaving a dead HTML page behind. I'd like to instead embed the applet inside the HTML page, so I can have a link create a popup window. As it is now, if you close the HTML page it closes the applet.
I used the generic jBuilder code to create the applet, and added this like to start()
HelpViewer frame = new HelpViewer();
The GUI is created using in the HelpViewer's constructor:
/** HelpViewer
* Creates a new HelpViewer for specified URL
* @param URL
public HelpViewer(String url)
this.setTitle("Insight Help");
utilities = MiscUtilities.getInstance();
// Chack if valid URL
try
// Check if protocal included
new URL(url).getProtocol();
// Valid protocol, so if pointing to specific HTML file, remove
Log.log(Log.ERROR, this, "Parse URL for hostname");
catch (MalformedURLException e)
// No protocol - therefore assume local
if (e.getMessage().startsWith("no protocol"))
baseURL = utilities.getRemoteURL() + "/docs/";
else
Log.log(Log.ERROR, this, e.getMessage());
//Set to error page?
// Create history
history = new String[25];
ActionHandler actionListener = new ActionHandler();
// Setup tabs
JTabbedPane tabs = new JTabbedPane();
tabs.addTab("Contents", toc = new HelpTOCPanel(this));
tabs.addTab("Search", new HelpSearchPanel(this));
tabs.addTab("Glossary", new HelpGlossary(this));
tabs.setMinimumSize(new Dimension(0,0));
// Setup toolbar
JToolBar toolBar = new JToolBar();
toolBar.setFloatable(false);
toolBar.add(title = new JLabel()); // title of current page
toolBar.add(Box.createGlue());
JPanel buttons = new JPanel();
buttons.setLayout(new BoxLayout(buttons,BoxLayout.X_AXIS));
buttons.setBorder(new EmptyBorder(0,12,0,0));
// Add back button
back = new JButton(utilities.loadIcon("ArrowL.png"));
back.setToolTipText("Back");
back.addActionListener(actionListener);
toolBar.add(back);
// Add forward button
forward = new JButton(utilities.loadIcon("ArrowR.png"));
forward.setToolTipText("Forward");
forward.addActionListener(actionListener);
toolBar.add(forward);
back.setPreferredSize(forward.getPreferredSize());
// Add home button
home = new JButton(utilities.loadIcon("Home.png"));
home.setToolTipText("Home");
home.addActionListener(actionListener);
toolBar.add(home);
// Add toolbar to panel
JPanel rightPanel = new JPanel(new BorderLayout());
rightPanel.add(BorderLayout.NORTH,toolBar);
// Setup Viewer Panel
viewer = new JEditorPane();
viewer.setEditable(false);
viewer.addHyperlinkListener(new LinkHandler());
viewer.setFont(new Font("Monospaced",Font.PLAIN,12));
viewer.addPropertyChangeListener(new PropertyChangeHandler());
rightPanel.add(BorderLayout.CENTER,new JScrollPane(viewer));
// Split Pane
splitter = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, tabs, rightPanel);
splitter.setBorder(null);
getContentPane().add(BorderLayout.CENTER,splitter);
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
getRootPane().setPreferredSize(new Dimension(750,500));
pack(); // causes window to fit the preferred size
setVisible(true);
SwingUtilities.invokeLater(new Runnable()
public void run()
splitter.setDividerLocation(250);
viewer.requestFocus();
gotoURL(url,true);
Any advice would be appreciated!

There are 2 possible solution.
1. Do not leave that window empty. I.e. write there a message "DO NOT CLOSE THIS WINDOW"
2. Do not open new frame. Add all components to your applet. This is not very difficult.

JBuilder Question - Where do i put the code?

I am building a jList using the designer in
Jbuilder. In what event procedure do i put the
code that assigns an array and so on?
thanks for any help
maggie evans

Typically you'll code the initial population of UI components in the jbInit method. If you want to dynamically populate the list as a result of a selectable UI component being clicked then put the code in the action performed method for the 'clicked' component.

Trying to figure out why code is inoperable in Jbuilder

Dear Fellow Programmers,
Yesterday, I went to a site that contained sample java code. I found a basic construct for a simple "Hello World" Gui. I proceeded to copy and paste the code into the jbuilder edit window. However, the program would not compile until I made certain changes to the code. Additionally, I learned a great deal during the debugging process.
I will the list the original code-listing first, and the altered listing second.
I guess if there is anyone willing to help, I need to know if the code used in jbuilder is program specific. Basically, do you have to make changes to regular java code in order for it to work in JBUILDER?
import java.applet.*;
import java.awt.*;
public class HelloWorld extends Applet
public void init()
public void stop()
public void paint(Graphics g)
g.drawString("Hey hey hey",20,20);
g.drawString("Hellooow World",20,40);
IN ORDER TO GET THE ABOVE CODE TO COMPILE/RUN, I HAD TO MAKE THE FOLLOWING CHANGES:
package test2;
import java.awt.*;
//import java.awt.event.*;
import java.applet.*;
import javax.swing.*;
public class SIMPLE extends JApplet
boolean isStandalone = false;
/**Get a parameter value*/
public String getParameter(String key, String def) {
return isStandalone ? System.getProperty(key, def) :
(getParameter(key) != null ? getParameter(key) : def);
public SIMPLE() {
public void init(){
try {
jbInit();
catch(Exception e) {
e.printStackTrace();
public void stop()
private void jbInit() throws Exception {
this.getContentPane().setBackground(Color.red);
/**Main method*/
// I HAD TO ADD THIS MAIN FUNCTION TO RUN THE PROGRAM FROM THE COMMAND LINE
public static void main(String[] args) {
SIMPLE applet = new SIMPLE();
applet.isStandalone = true;
JFrame frame = new JFrame();
//EXIT_ON_CLOSE == 3
frame.setDefaultCloseOperation(3);
frame.setTitle("I CAN'T WORK");
frame.getContentPane().add(applet, BorderLayout.CENTER);
applet.init();
applet.start();
frame.setSize(400,320);
Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
frame.setLocation((d.width - frame.getSize().width) / 2, (d.height - frame.getSize().height) / 2);
frame.setVisible(true);

The example that you were trying to run was an Applet.
The first line tells you this:
public class HelloWorld extends Applet
It requires that it be run within a browser.
The sample you wrote is a stand alone application. It contains a main method. It runs from the console.

Jbuilder + Apache ADF = free production license code?

Can I use Jbuilder with the Apache ADF components to create production use code with a no cost license?
Can the Oracle 10G database be used at any level of production use with a no cost license?
Is J2EE required for code developed end to end on Jbuilder?
Thanks,
JOD

JBuilder is a Borland product which costs money.
If you are talking about JDeveloper - than JDeveloper is free - and you can use any free libraries in it such as the Apache components.
The only thing to be aware of is that the ADF Framework has a cost if you deploy it to non Oracle application servers.
As far as the database goes there is the free Oracle XE database - it has some limitation in its license and features - you can read about this when you download it.
For more information on JDeveloper and ADF pricing google for "JDeveloper pricing FAQ".

I can't get this command line code to work in JBuilder...

Dear Experts,
I built a simple JAVA program, in JBuilder, that displays a GUI with a label. It works when I am in JBuilder clicking on the Run button. But when I try to run
"-classpath /[home]/ jbProject/ProjectNameRob/RobClasses ProjectNameRob.RobClsJav" from the command line I get this message:
"Could not create Java Virtual Machine."
I am in the jdk/bin directory and I still can't figure out how this thing works. Could the experts come forth and help me with this problem?
Thank you,
Robert L. Perkins

Well, this won't be an exact answer for you because I'm not sure which run of "java -cp ...." did it for me, but I was able to get a run of a class in JBuilder 3.0 from the command line.
I created a project called test_1.jpr. It has the following 3 files:
Controller.java // contains a main( ) method
test_1.html
Test1.java // extends from JFrame
On my system, the directory structure is:
C:\JBuilder3\myclasses\test_1
Tried:
C:\JBuilder3\myclasses\test_1>java Controller // no good
C:\JBuilder3\myclasses>java test1.Controller // no good
C:\JBuilder3\myclasses>java -cp %CLASSPATH%;C:\JBuilder3\myclasses Controller // no good
C:\JBuilder3\myclasses>java -cp %CLASSPATH%;c:\JBuilder3\myclasses\test_1 Controller // no good
C:\JBuilder3\myclasses>java -cp %CLASSPATH%;C:\jbuild~1\myclas~1\test_1\Controller
That resulted in the "usage" output to appear for the "java" .exe. But right after that, I did:
C:\JBuilder3\myclasses>java test_1.Controller
and wham, the application ran fine. I'm running Windows 98 SE, if that helps. Probably won't help you much, but I just kept messing around with it and then it worked. Voodoo.

Old school code :-(

Hey,
I been writing my game and wanted to show somone my game. However i can only get the newer java vm to work on his computer. Well i been writing my code for an older version becuase JBuilder wouldnt configure properly.
Well, the game works but the buttons dont work and i get a white background instead of black in the newer java vm. but everything works in the old one.
Well i want to update my code to the newest java VM.
The one i been using is:
java version "1.2"
Classic VM (build JDK-1.2-V, native threads)
ok, i post my code and i be most thankfulif you can show me where i need to modify the code. There are images in the program which i feel are not needed, so if you wanna compile it and run it, just use random images or block the code that does it so it can be tested
OK, thanks in advance, sorry for the length of the program but i kinda kept it tidy and readable.
ALso sorry its not documented :-(

Did you get any compile errors?
Are you getting any messages/exceptions at runtime?
The same code, compiled with a jdk 1.2 works fine?
(( You've tested this.. (my thought is that maybe somewhere you changed something but didn't recompile that has no broken execution...) you've compiled those specific files with the old jdk, just to make sure))

Applet working on JBuilder but not on appletviewer!!!!!

I ve made a keybord.Here some buttons are missing. The user presses the buttons and shapes a word!When the jButton22 is pressed(Comparison button) the applet tells him if the result is true or false and displays an image(imageIcon foruser in jlabel forusers) with the correct result!!The jlabel for users is setVisible(false) and setVisible(true) when the comparison button is pressed and the result is wrong.My problem is that the jlabel works fine in JBuilder but when i run the applet in appletviewer the jlabel forusers isnt showing!!If i minimize and maximize the window then the label appears and from that point is working properly!Any suggestions would be appreciated!Thank you!!

I performed some testing on your program, and get an ArrayIndexOutOfBoundsException on one of the buttons. So, I guess there have to be some implementation logic error.
Since I have no idea what your program is trying to achieve, here's what you can do:
1. Try to shorten your program.
2. Add your code piece by piece.
3. Perform some logic testing.
4. Repeat steps 2 & 3.

How can I generate a component array using JBuilder?

Now I'm using JBuilder to design my program's GUI. I wanted a JTextField array like this:nums[0]~nums[2].So I draged three JTextFields into the container at JBuilder's design view. But when I set the names of them as nums[x](x=0,1,2). I got a Error Message. It told me that I used a illegal name. How should I do, please?
thank you a million!

The DIO ports on a MIO will not satisfy your needs (unless you move to LV RT).
They do not support buffered outputs.
Your update rate (how often you can set the port and clear it) is going to be limited by how fast (a-hem slow) windows will let you iterate,
and,
be non-determinstic.
You could use,
1) LV RT with the existing board, or
2) FieldPoint PWM module, or
3) Arbitrary waveform generators, or
4) HS DIO board, or
5) use the analog output of your baord where you que-up a 0 -5V waveform of the proper shape (i.e. make sure that the duty cylce fraction of the update values are high, the rest low).
This is just to get a PWM signal out.
Now there is another issue. Determinism. How often do you plan on reading your inputs and making a change to you
r PWM? If you plan on doing more often that 10/second, write your code to handle windows going out to la-la land when you expect it to be working.
Can you tell I like LV-RT.
I hope my ramblings have helped.

Mysql driver and Jbuilder 2005 foundation

I am trying to connect to a mysql server using jdbc and the mysql drivers. Specifically version 3.1.7. I will post my code here although I believe the code is correct and that I have a classpath issue with jbuilder. The error I am receiving on both build and run time is:
Exception in thread "main" java.sql.SQLException: No suitable driver
     at java.sql.DriverManager.getConnection(Unknown Source)
     at java.sql.DriverManager.getConnection(Unknown Source)
     at methodclassespkg.DummyTester.main(DummyTester.java:39)
I installed the mysql .jar driver file in the jdk1.5/lib/ext as the read me file that came with the drivers stated. I have changed the default jdk to the jdk1.5 update 2 that I installed. I imoprted the .jar driver file into the project and even added the file under tools/configure/libraries. But I still receive this error witht his code
package methodclassespkg;

Again I am running the free version which does not allow me to access the enterprise tab, I mention this because I saw a solution to this issue that allowed for importing the database driver using tools/enterprisesetup/database drivers. but I do not have access to this functionalitity.
Jeremy Reed

Thank you for the fast response from everyone. WIth you assistance I did reach a solution. I turns out I wasnt calling the driver correctly, syntactlically.
For anyone googling a similar issue as mine, for j connect, your statement must be in the form of jdbc:mysql://yourhost/database?user=name&password=password
that was my mistake

UML & Code Generation (RAD)

Hey everyone,
I'm evaluating Java IDE's right now and I'm working with a group that uses a tool called Popkin to do their design in UML. I'm trying to find a Java IDE that can import (via XMI) those diagrams to do the code generation.
Rational and TogetherSoft have integrated environments that couple the code and design (As you code, the UML is updated and as you create UML, the code is updated, etc.)
I'm wondering though, if you use something like JBuilder, how can you import the UML from another tool? Has anyone messed with Popkin before or tried to integrate something like this?
Thanks,
Will

Why there is no UML tab in JBuilder X developer?

I have just started to use JBuilder X Developer Evaluation edition. And to
my surprise, I did not see UML tab there (I did see Source, Design, and other
three tabs there). So is it that I did not do something right, or the software just
does not have UML tab (A JBuilder Enterprise book did mention the UML tab.)?
I hope the UML tab is not solely for JBuilder Enterprise Edition. Please help
me to clarify the myth. Thank you.

I have never used JBuilder, but I have heard from a lot of people that dislike it! Personally, I use TogetherJ for UML, but I don't really like the fact that it ties your diagrams to code that it generates behind the scenes, and also it is not free. ArgoUML is very good (and free), and doesn't constrain you as much (there are arguments for and against this). I appreciate that you might want to use JBuilder because you are used to it, but I am writing this follow-up in case you don't know of any other tools that can create UML diags ;o)

Need someone to chek my code n tell me if the asserts work. Please!!

Hi , its importante that someone could help me on my code.
the code is the greatest common divisor ( Maximo divisor comum)
Well , the code is all right but i can't run it with the asserts , im using Eclipse 3.1 , the level of compilation is 1.3 .
It says that ignores de asserts but when i compile it gives me error on assert expression.
I would like to someone could test this code in another JAva editor like XEmacs or JBuilder ,anything that works with asserts and accept them.
Someone working with linux could test this too?
Just wanna see if the assertions are right , because i can't run the program with them in the eclipse. :S
Its importante, help me please.
Code:
import pt.iscte.io.*;
public class gCommonDivisor {
public static void main(String[] args){
      assert 0 < n : n;     // <-- THERE THEY ARE : (
      assert 0 < d : d; // n is the numerator and d is the denomi.
System.out.println("Insira valor do numerador: ");
          int n = Teclado.intLido();
          System.out.println("Insira valor do denominador: ");
          int d = Teclado.intLido();
          int r = mdc( n, d); // modulo para o maximo divisor comum
          int den = denominador(r , d); // modulo para denominador simplificado
          int num = numerador(r, n); // modulo para numerador simplificado
          // Output do Maximo divisor comum e da frac�ao reduzida
          System.out.println("Maximo divisor comum entre "+ n +" e "+ d +" � "+ r);
          System.out.print("Frac��o reduzida de "+ n +"/"+ d +" = "+ num +"/"+ den);
           * @pre V.
           * @post gcd = maximo divisor comum
          static int mdc(int n, int d){
          int gcd = 1;
          int k =1;
          while (k <= n && k <= d) {
               if (n % k == 0 && d % k == 0)
                    gcd =k;
               k++;
               return gcd;
          // numerador simplificado
          static int numerador(int r , int n ) {
          int numerador = n / r;
          return numerador;
          // denominador simplificado
          static int denominador(int r , int d ) {
          int denominador = d / r;
          return denominador;
} Thank you so much .
Please help me!
Sorry about the language of the code. but dont worry about it, the code works fine without those two asserts after the main.
kind regards,
Josh

wow i forgot to say that u just need to change the
expression to read the input from the console.
U dont have the iscte_io.jar
change int n = Teclado.intLido();
and int m = Teclado.intLido();
cuz u don't have the Teclado( Keyboard) i had to import pt.iscte.io.Teclado;
to read the input given by the user.
thks

Import JBuilder into Sun Java Studio Enterprise 8

I have a few JBuilder projects that I would like to import into SJSE8.
I have read all the guides for migrating projects from JBuilder but I cannot see how I actually get the Import Project module.
SJSE8 is supposed to be built on NetBeans5.5 but when I use the Update Center I cannot see the Import JBuilder Project module. How can I find the module and install it? Perhaps I need to get the .nbm file, but finding this seems to be difficult.
Please Help,
Rob

For questions on 'Java Studio Creator', you may want to post on the Creator forum at http://forum.java.sun.com/forum.jspa?forumID=881 .
The following are possible options but they are not guaranteed to work:
Have you tried connecting to the all the available update centers in Creator ide's autoupdate client and check if 'jbuilder importer' plugin is available from one of them?
If not, you should be able to download the nbm separately from:
http://www.netbeans.info/uc/show_uc_content.php?nbver=50&auver=1.15&uctype=stable
You can then use 'Install manually downloaded nbm' option in the autoupdate wizard. Again, this may or may not work..
Also: You should consider upgrading to NetBeans 6.0.
NetBeans 6.0 is an all-in-one-ide that is the recommended migration path for both Creator and Studio users and is the latest version available:
