Labels in jdk1.4

Hi, I just started using jdk1.4 and all the labels that used to have this java light purple color are now black. Is this a bug in jdk1.4 or do you have to manualy configure the labels in jdk1.4.

What are you seeing different the background or the forground color? When I switched from jdk1.3 to 1.4 I didn't see any difference in the labels (using Metal or Motif look and feel) . The label foreground color was being set to black and the background was default.

Hi Trinidad,
Thanks for your help!!!
1.
I didn't install EventSender and DIProxy yet, I tried first to upload and deploy the zip files, but I couldn't open the Itegration Application Explorer.
2.
The jvm.dll file is in in the folder pointed by the logs: C:\Program Files (x86)\SAP\SAP Business One Integration\jdk1.5.0_xx_sap\jre\bin\server
and it is also in C:\Program Files (x86)\SAP\SAP Business One Integration\jdk1.5.0_xx_sap_64\jre\bin\server
I tried running the file java5w.exe, but I got an error message:
Access is denied
Unable to open the service tomcat5
Thne I managed to open it by "rua as administrator".
the Java Virtual Machine path is points to the java 1.5 version folder.
Is it possible that the reason that the service can't start is related to administrator rigts??
In the properties in the Integration Service (services.msc):
It is set to be run with the local system account.
all other properties looks fine.
in the properties of the tomcat5.exe (and tomcat5w.exe , I tried both)
In the Compatibility tab I tried setting the flag "Run this program in compatibility mode for" to Vista, windows 7, and server 2008
I didn't have the option of Windows XP.
I have also set the Privilege level of: "Run this program as administrator" to true.
But still the service won't start.
What can be the problem?
What else can I check?
Thanks a lot,

Andrew,
Thanks for the lightning response... but the problem has been solved.
I rebooted again, and installed again (didn't download again because the filesize checked out) and now it works fine, and I'm none the wiser as to the root cause of the problem, except that rt.jar has magically appeared:

Problem in reading the JDK1.4Logger configuration file from java prog

I have written a java program and want to log the messages in a log file , I'm using commons logging with JDK1.4logger as logging subsystem .
I am facing the problem in reading the JDK1.4Logger configuration file which is commons-logging .properties file from my java program as a result my log messages are appearing directly on the screen while I try to run program , during compilation no error is shown . I have tried to set java.util.logging.config.file ="Path of my commons-logging .properties file " by setting system properties also.
Please suggest the appropriate solution for this .

Some webservers won't recognise the resource bundle provided in message-resources
In that case, you need to specify that resource bundle information in web.xml at the time of specifying the action servlet like this. Check for the init-param application.
<servlet>
 <servlet-name>action</servlet-name>
 <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
 <init-param>
 <param-name>application</param-name>
 <param-value>resource.ApplicationResource</param-value>
 </init-param>
 <init-param>
 <param-name>config</param-name>
 <param-value>/WEB-INF/struts-config.xml</param-value>
 </init-param>
 <init-param>
 <param-name>debug</param-name>
 <param-value>2</param-value>
 </init-param>
 <init-param>
 <param-name>detail</param-name>
 <param-value>2</param-value>
 </init-param>
 <init-param>
 <param-name>validate</param-name>
 <param-value>true</param-value>
 </init-param>
 <load-on-startup>2</load-on-startup>
</servlet>In this, the drawback is, you can not specify the key for your resource bundle. In the JSP, you have to access the property like this.
<bean:message key="label.fName"/>

Sirs,
I've tried to compile the following code,

JFrame frame = new JFrame("HelloWorldSwing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Add the ubiquitous "Hello World" label.
JLabel label = new JLabel("Hello World");
frame.getContentPane().add(label);
//Display the window.
frame.pack();

Thanks in advance.

How long have you been using Java? Swing has been in the javax.swing package for a long time now.
Your compiler errors don't match your source:

Iconed labels and iconified JFrame

Hello everybody,
I have a problem with a strange behaviour of a JFrame.
In order:
1. I initialize a JFrame with a JSplitPane
2. The left component is a JPanel containing 64 JLabels, each with an Icon in it.
When the frame is coming up, everything is displayed proper. But when I iconify the frame and deiconify later nothing is to see, but a blank frame. The labels will be redisplayed after clicking on the position, where the splitpane-divider should be.
I'm using jdk1.4
Can anybody helpme?
Thanks

hi,
hope you've used the frame's getContentPane() method for adding the splitpane, if yes, then that might be some kind of a bug, anyways, add a window listener overriding the windowDeiconified(WindowEvent) method & call the frame's repaint() method,
hope this helps you,
reagrds,
Afroze.

Applet label and button attributes being reset.

Using JDK 1.4 through 1.6, IE6, JBuilder 2005
I have an applet with a panel that displays the status of external devices and allows the device status to be changed. Here is a brief description.
The applet has a class that extends JPanel.
The panel has a set of JButtons that display a color representing the state of the device and text that shows the button action (Open or Close). By default, the JButtons are Green with text = "Open". These are initialized in the init() method of the class that is called only once when it is initialized.
The panel display class has one method of interest:
setDeviceStatus() - updates the color and text of the JButtons.
This is the ONLY ways these components can be changed outside the init() method of the class.
The method has a System.out.println() statement immediately before any change in text or color.
There is a simulator applet that is used to send messages via sockets to the display applet.
Here is what happens.
1) Applet and panel are initialized correctly.
2) Simulator applet sends message to update the color and text of a JButton
3) The message is recieved by the display applet and the setDeviceStatus() method is called.
4) The print statements before the setText() and setBackground() methods of the Jbuttons are called and new states printed.
5) Color and text changes on the JButton to Red and Close.
6) Cursor is moved from JButton and JButton focus is lost.
7) JButton color and text revert to initial default state of Green and Open.
There is only ONE call to the setDeviceStatus() method. This call updates the color to RED and text to CLOSE.
As soon as focus is changed, the display updates to initial values WITHOUT calling the setDeviceStatus() method.
The behavior is different in JDK 1.4 and 1.6
JDK1.4) The text and background color change back after focus is lost by either:
a) Clicking on another window.
b) Creating an expose event by hiding and redisplaying the applet
JDK1.6) The text and background color change back after the cursor is moved off of the button.
CAN ANYONE EXPLAIN HOW TO KEEP THE UPDATED STATUSES????

Hi Denes,
I' paste it here ...
 
<table class="t10Button" cellspacing="0" cellpadding="0" border="0" summary=""> 
<tr> 
<td class="t10L"><a href="#LINK#"><img src="#IMAGE_PREFIX#themes/theme_10/button_left.gif" alt="" width="4" height="24" /></a></td> 
<td class="t10C"><a #BUTTON_ATTRIBUTES# href="#LINK#">#LABEL#</a></td> 
<td class="t10R"><a href="#LINK#"><img src="#IMAGE_PREFIX#themes/theme_10/button_right.gif" width="4" height="24" alt="" /></a></td> 
</tr> 
</table> 
does this work ...?

Html text in label is moving when used as a renderer in a table cell

Hi everybody,
Because it is impossible to use gradient background for html, I created a custom TableCellRenderer that uses a JLabel (for the html text) inside a JPanel with a gradient background. (I use jdk1.5.0_06)
However, in the code that I'm posting, something strange happens. The text is moving up and down as I move with the arrow button along the first row, from left to right and backwards, crossing the entire row.
You can see for yourself. If someone can explain this behavior, please help!
public class MyFrame extends javax.swing.JFrame {
 public static void main(String args[]) {
 new MyFrame().setVisible(true);
 public MyFrame() {

 table.setModel(new javax.swing.table.DefaultTableModel(
 new Object [][] { {"", "", ""}, {"", "", ""}, {"", "", ""}, {"", "", ""}, {"", "", ""}, {"", "", ""} },
 new String [] { "Title 1", "Title 2", "Title 3" }
 public Class getColumnClass(int columnIndex) {
 return String.class;
 table.setRowHeight(30);
 table.setRowHeight(0,100);

 g2d.setPaint(new java.awt.GradientPaint(0,0,c2,0,this.getHeight(),c1,false));
 g2d.fillRect(0,0,this.getWidth(),this.getHeight());
}

If someone can explain this behavior, please help!Can't explaing the behavour, but it seems to work fine when you use a JeditorPane or JTextPane which are specifically designed to display HTML.

XSQL with jdk1.2.2 - javai.dll error

I successfully used the xsqlCommandLine utility with jdk1.1.7. When I try with jdk1.2.2, I get an error that javai.dll is not in the path. If I put javai.dll from the 1.1.7/jre/bin in my path, the xsqlCommandLine process runs without end, as if windows (NT) is searching for something else. I'm using the latest classes12.zip and the xmlparserv2.jar files. Any help?
Thanks.

Printing with jdk1.1.8

Hi...I am developing an application for mac(classic) where i need to provide the print functionility.Now Mac supports only upto jdk1.1.8.Has someove ever developed printing with this...code will definetly help.........

You should start with java.awt.Toolkit.getPrintJob(java.awt.Frame, java.lang.String, java.util.Properties)
to obtain a PrintJob.
From the PrintJob object you can get a Graphic by using the Method getGraphics().
On you first try, produce the Output for the page in some visible AWT component, so you can see it.
E.g. put your stuff in a panel and add this panel to a Window.
Then print the Top-Level Component ( thats the panel) that contains your Output by
calling printAll(Graphics g) on it, with the Graphics object from above.
Notes:
You have to take care for Printer borders - your output will be clipped there.
Code was tested on JDK 1.3, but is designed for JDK 1.1
Example: Test.java
import java.awt.*;
import java.awt.event.*;
public class Test {
static Frame f;
static Panel panelToPrint;
static class Handler implements ActionListener {
public void actionPerformed(ActionEvent e) {
//get a PrintJob (opens the native window)
PrintJob pj = Toolkit.getDefaultToolkit().getPrintJob(f, "Print-Test", null);
//get a graphics object to draw on
Graphics g = pj.getGraphics();
panelToPrint.printAll( g );
//end the print job, now it is sent to the printer
pj.end();
f.dispose();
public static void main(String args[]) {
f = new Frame("Test");
Button b = new Button("Print...");
b.addActionListener(new Handler());
f.add(b,"South");
panelToPrint = new Panel();
panelToPrint.add(new Label("Hello World"));
panelToPrint.add(new Label("Hello World"));
panelToPrint.add(new Label("Hello World"));
panelToPrint.add(new Label("Hello World"));
panelToPrint.add(new Label("Hello World"));
panelToPrint.add(new Label("Hello World"));
panelToPrint.add(new Label("Hello World"));
panelToPrint.add(new Label("Hello World"));
panelToPrint.add(new Label("Hello World"));
panelToPrint.add(new Label("Hello World"));
f.add(panelToPrint, "Center");
f.setSize(new Dimension(300,400));
f.setVisible(true);

Urgent... Adding focus listeners to labels..

Hi,
Is it possible to handle focus events on labels? I tried to add a FocusListener to a label, but the labels aren't receiving any focus. Is there any way to achieve this? I was trying to build a table component with each table cell being represented by a label. The user should be able to navigate across the table cells using arrow keys. Is there any other alternative than using a label?
regards,
Anand

hi!
from jdk1.4 in java.awt.component class has setFocusable(boolean focusable) method. use this to set the label focusable.
i hopen this can help you

JDK1.3 problems

I have just installed jdk1.3 and am having some problems. The System.out.println(); and the System.out.print(); commands don't do anything! I am also unsure how to set the PATH so that I don't have to type the whole directory to compile or run the programmes. If anyone has any ideas I would be gratefull.
Thanks

This may duplicate some of what you've already done, if so fine. But please verify you've done exactly what is written or know why you shouldn't before proceeding. You may want to print these instructions before continuing.
To download the correct software, go here:

Install the software according to the preceeding instructions
Below is a Helloworld program, copy and paste it into your editor and save it as "HelloWorld.java" Use capitalization, Java is case-sensitive. If you're using Notepad, quote the name when saving, otherwise Notepad adds ".txt" to the name. Go to DOS and check that you've got the file where you want it and that it's named correctly.

public class HelloWorld {
public static void main (String[] args) {
System.out.println("Hello World!");
In the same directory as HelloWorld.java, enter "javac" - the program should print out a list of options, if not, set your PATH - see below.
In the same directory as HelloWorld.java, enter "javac HelloWorld.java" and the javac compiler will create HelloWorld.class. If it was successful it will not give any messages. Check that the file is created.
In the same directory as HelloWorld.java, enter "java -cp . HelloWorld" with the spaces and the period. The program will run.

Problems After shifting swing application from jdk1.3 to 1.4

hi,
i have shifted my Swing application from jdk1.3 to 1.4, some component settings changed in j2se1.4. are listed below
1). i have added JComboBox to JPanel using BoxLayout, in jdk1.3 it is normal where as in 1.4 comboBox height is increased to panel height.
Sample code
(in a Panel)
     setLayout(new BoxLayout(this, BoxLayout.X_AXIS));
add(getYearComboBox());
     add(getMonthNameComboBox());
     add(getDayOfMonthComboBox());
2). in jdk1.3 the icon which is set to JFrame is visible in the JOptioPane.showConfirmationDialog() also, but in 1.4 the icon is not visible in conformation dialog box.
Sample Code
in a JFrame's constructor
public OptionPaneTest()
ImageIcon icon = new ImageIcon("icon.gif");
setIconImage(icon.getImage());
setSize(250,100);
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent e) {
                    System.exit(0);
setVisible(true);
JOptionPane.showMessageDialog(this,"hai", "Hai",JOptionPane.WARNING_MESSAGE);
3). the Labels added to the panel or frame are displaying in light blue color with jdk1.3 and the same label displaying in black with j2se1.3
Sample Code
in a JPanel
setLayout(new BorderLayout(20, 20));
add(new JLabel("Testing Label Color"), BorderLayout.CENTER);
please send solution to any or all.
thanks in advance,
Pavan.DV

Thanks for your sugession.
You realized me by showing the fact that there are no many classes
Keep suggesting like this.
I don't even know how to see the API documentation Before you told me.
Don't take any issue as simple thing and never give foolish suggessions like this.

Right. Using WebLogic RMI proprietary implementation (t3) with 6.1 requires
1.3 on the client side. If you absolutely have to use 1.2 on the client side,
IIOP should work - I just tried this and it looks like WebLogic 6.1 implements
EJB spec interop requirements pretty well.

I saw an article saying use iiop and then deploy your beans for such. I can
get context over IIOP using jdk1.2.2 to WLS 6.1. I have not yet deployed
beans or recompiled anything to try this all the way. Does this work?
Should I proceed? or is there a gotcha?

6.1 requires 1.3 on the client. (it uses dynamic proxies, so 1.2 willnot
work).
