- Executing a jar fileI have the following code
/*
WinTest.java
*/
import java.io.*;
public class WinTest {
public static void main (String args[]) {
String line;
Process backgroundProcess;
try {
// Start the other process
backgroundProcess = Runtime.getRuntime().exec
("d:\\program files\\cprog.exe");
}
catch (Exception e) {
System.out.println(e);
}
}
}
If I execute the class file from a cmd windown I get the start up
screen from the cprog.exe, however as I would like to dispense with
the dos window I packaged the class into a jar file
First creating a text file called WinTest.txt containin the single
line
Main-Class: WinTest
Then create the jar file
jar cmf WinTest app.jar WinTest.class
I associated the jar file with the java.exe in the SDK lib
But when I double click to execute the jar file a dos window pops up
disappears but no start screen from the cprog.exe is shown
I'm sure it is a severe user error must I have to admit to being
stumped and help would be nuch appreciated

- database content as objectsI wonder what is so appealing in mapping of database content to
predefined Java (or some other language) objects.
There is a problem with joins in he first place. There is lot of coding
and processing overhead.
I found it more elgant to store data in HashMaps. If I need an object,
I could always provide a class with a constructor that takes HashMap as
parameter.
Reporting can be much easier that way, too. I used it in a couple of
projects, and find it very handy.

- Component inside JList not painting; now resolvedI have set up a JList to work with its own ListModel and
ListCellRenderer. The symptom, my component does not
display any text. That is the list box is
completely blank. From the debugging, I saw it displayed the desired
text. And, we saw that the list box scrolled when there was more data
than can be displayed.
The problem turned out to be that I defined paint() rather than
paintComponent(). What was strange was that I was able to use other
classes extending Component that I wrote and return them
from the ListCellRenderer. These had the same mistake
of putting the display logic in paint() rather than paintComponent();
Yet those Components worked fine and this error in the class notes from
which
I taught our GUI course since 2001.
One of my students , Mr. Kevin Kraus,
elucidated the solution to this problem -- Thanks!
This was also discussed in this group in
relation to a post from John Creighton on September 2 2001.
Since, this is an easy error to make, it is worthwhile having the
reminder, here.
I did not see anything saying this in the FAQ but section 3.4
told our users not to use Component.getGraphics(). They were told
to override "paint()(AWT)" or "paintComponent()(Swing)"
I am sending a suggestion to Mr. Weidenfeller
of new wording to help people trouble shooting their
programs.
Here is my component definition:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class NumberComponent extends JComponent {
String FontName;
String ToDisplay;
int Size;
boolean Selected;
Font f;
void setSelected (boolean S){
Selected=S;
}
NumberComponent (String S) {
ToDisplay = S;
Size = 12;
FontName="Arial";
}
NumberComponent (String S, String F, int size) {
Size=size; FontName = F; ToDisplay = S;
}
public void paint (Graphics g) {
System.out.println ("font Name " + FontName + " Size " + Size);
if (!Selected) {
f = new Font (FontName,Font.PLAIN,Size);
}
else {
f = new Font (FontName,Font.BOLD,Size);
}
//g.setFont(f);
g.setColor(Color.black);
//g.fillRect(10,10,30,20);
g.drawString (ToDisplay,0,0);
System.out.println (" here " + ToDisplay + " hc " + hashCode());
}
public Dimension getMinimumSize() {
if (!Selected) {
f = new Font (FontName,Font.PLAIN,Size);
}
else {
f = new Font (FontName,Font.BOLD,Size);
}
int Width = getFontMetrics(f).stringWidth(ToDisplay);
int Height = getFontMetrics(f).getHeight();
System.out.println (" Width " + Width + "Height " + Height);
Dimension D = new Dimension (Width,Height);
return D;
}
public Dimension getPreferredSize() {
return getMinimumSize();
}
public Dimension getMaximumSize() {
return getMinimumSize();
}
}
Here is the output from the list box that is using it to display:
@toolman#/home/leffstudent/412/final1 >java LMX Numbers.xml

Here is the ListCellRenderer I defined:

import org.w3c.dom.*;
import org.xml.sax.*;
class NR implements ListCellRenderer {
public Component getListCellRendererComponent (
JList list,
Object value,
int index,
boolean isSelected,
boolean cellHasFocus)
{
Element N = (Element)value;
NodeList NL = N.getChildNodes();
Node TextNode = NL.item(0);
String NumberText = TextNode.getNodeValue();
String Font = N.getAttribute("Font");
String SizeText = N.getAttribute("Size");
System.out.print ("Number Text " + NumberText + "Font is " + Font + "
Size " + SizeText);
NumberComponent NC;
if (Font != null && Font.length() != 0 && SizeText!=null &&
SizeText.length()!= 0) {
int Size = Integer.parseInt(SizeText);
NC = new NumberComponent(NumberText,Font,Size);
}
else {
NC = new NumberComponent(NumberText);

System.out.println ("NC " + NC.hashCode());
return NC;

- a common yet hard-to-resolved problem for Java GUI size!The Java application GUI (setPreferSize to some hardcoded dimension)
gets smaller when it comes to wide screen (Dell 16:9 laptop), and the
users have to resize the GUI every time they are launched (so as to see
the action buttons). This problem seems to happen only for 16:9 wide
screen so far.
Question:
1. What are the factors deciding the swing (awt) GUI size, besides
resolution and font? Is wide screen really an individual factor?
2. How to formulate a universal good GUI size? Or any examples to
define different sizes for different display-cases?
Thought the following functions might be needed, although I heard that
Toolkit.getScreenResolution() cannot really detect screen resolution.
Toolkit.getScreenResolution(), Toolkit.getScreenSize(), getFontSize()
Any example or information will be highly appreciated!

- What's the proper way to use SocketChannel.finishConnect()?What's the proper way to use SocketChannel.finishConnect()?
I've read the documentation but couldn't comprehend what is written for it.
I've seen examples where it is placed:
1a) Right after SocketChannel.connect() (without while loop)
SocketChannel sc = SocketChannel.open();
sc.connect(...);
sc.finishConnect();
sc.configureBlocking(false);
sc.register(selector, SelectionKey.OP_READ);
1b) Right after SocketChannel.connect() (with while loop)
SocketChannel sc = SocketChannel.open();
sc.connect(...);
while (!sc.finishConnect()) {
}
sc.configureBlocking(false);
sc.register(selector, SelectionKey.OP_READ);
2a) When iterating the Selector.select() values (without while loop;
SocketChannel sc = SocketChannel.open();
sc.connect(...);
sc.configureBlocking(false);
sc.register(selector, SelectionKey.OP_CONNECT);
... {
if (sc.isConnectionPending()) {
sc.finishConnect();
}
sc.register(selector, SelectionKey.OP_READ);
}

I find this a highly unusual situation. Ordinarily, you would have at least
a couple of environment variables displayed.
>

To create a CLASSPATH enviorment variable where none exists, do:
set CLASSPATH=C:\XYZ;D:\ABC
and press <ENTER>.
To add information to an existing CLASSPATH [you can choose whether to place
it before or after existing data] do:
:: Before existing data
set CLASSPATH=%classpath%;C:\XYZ;D:\ABC
or:
:: After existing data
set CLASSPATH=C:\XYZ;D:\ABC;%classpath%
and press <ENTER>.
Note, though, this changes the settings for the current console window [i.e.
DOS Window] only - the settings are lost once you close it. For a more
permanent solution:
* Edit 'autoexec.bat' file to include the above statements - this
applies to older Windows versions
* Use the System applet in the Control Panel to edit Enviromnent
Variables [for W2K, and XP]
I hope this helps.

That is not the issue. The issue is whether there are mechanisms to
detect the error or you simply get undefined results.
Think for example writing C code where you failed to initialise a
variable. This was legal. Most of the time it was initialised to 0.
But sometimes it was not, leading to a need for a timeout in a padded
cell. It STRONGLY matters if the compiler/run time can detect the
error.
It is almost irrelevant if the given code is technically legal.

- Beware of disabled ActionHi !
just a note to warn you about some javax.swing.AbstractAction problem
My GUI dispays a JButton.
depending on the user's state, I do a setAction(AAction)
or a setAction(BAction).
AAction and BAction each extend AbstractAction and possess their own icon
(ImageIcon).
Here is a sample scenario :
1) button.setAction(AAction)
2) AAction.setEnabled(false)
3) button.setAction(BAction)
4) BAction.setEnabled(false)
the result of this is : the Action linked to the button is BAction as
expected, and the icon is...AAction's disabled icon (original icon greyed).
The only workaround I've found is to do button.setDisabledIcon(null) before
any new setAction()
It seems that an AbstractAction doesn't possess a disabled icon on its own,
and relies on the JComponent's one.
The first time, 1) and 2) have the consequence of creating a disabled icon
for my button , which doesn't have any at the beginning.
Then, 3) and 4) won't change this disabled icon, because the button now has
one

- What means %10.7f?Hi,
My code has:
System.out.printf("%10.7f", aDouble);
My intention is to print out the value of a double variable following
the rule: a)the maximum space is 10; b)have 7 digits after the decimal
point.
But there is a bug here, I found. If aDouble < 100, it is fine; If
aDouble >= 100, it will take 11 spaces, instead of 10 spaces. So I have
to manually change 10.7f to 10.6f. What a pain!
Could you help me out? Thank you.

java-programmer, jtextarea and html
Hi,
Is it possible for me to setup up jtextarea such that
it renders html.
Suppose I create a but "interpret html" which when clicked
goes through the text in jtextarea and
adds styles
for example if I have something like
<b>bold text here</b>
then this should be bold. Furthermore, it should hide these html
tags but not delete them, that way when i save the text, i save the html
tags as well.
thanks for any advice

Short answer no. Long answer Nope.
If you subclassed JTextArea, you could add
the functionality, but that would not be a
JTextArea anymore.
OTOH - JTextPanes and JEditorPanes
_do_ style text, you would be better off
investigating them.

I have the same problem, I want to display HTML formating text. I tried
JTextPane and JEditorPane myself. I placed them in a JFrame with
BorderLayout in the EAST side. But it seems that every time I try to
resize the window, the JTextPane or the JEditorPane cover all the JFrame
area. JTextArea works as expected. What is the problem?

Do you have anything else in that JFrame? If you dont then it behaves as
expected:
the component consumes all the space left.

- nio sockets + SetTcpNoDelay Exception...Hi,
I use Nio sockets in a production projet for a while, without a single
problem.
Today, without having made any change to the code, I had the bad surprise to
see the following exception in my logs :
java.lang.ClassCastException
at sun.nio.ch.OptionAdaptor.<init>(OptionAdaptor.java:27)
at sun.nio.ch.SocketAdaptor.opts(SocketAdaptor.java:253)
at sun.nio.ch.SocketAdaptor.setTcpNoDelay(SocketAdaptor.java:258)
at aks.net.AKSAcceptDaemon.run(AKSAcceptDaemon.java:135)
My code looks like : (file AKSAcceptDaemon.java)
Selector m_acceptSelector ;
... // selector initialisation
while (m_bRunning)
{
Set readyKeys ;
Iterator it ;
SelectionKey sk ;
ServerSocketChannel ssc ;
SocketChannel client;
while ( m_acceptSelector.select() > 0)
{
readyKeys = m_acceptSelector.selectedKeys();
it = readyKeys.iterator();
// Walk through the ready keys collection and process
date requests.
while (it.hasNext())
{
sk = (SelectionKey)it.next();
it.remove();
if (sk.isAcceptable())
{
ssc = (ServerSocketChannel)sk.channel();
client = ssc.accept();
client.configureBlocking(false) ;
// HERE IS THE GUILTY LINE
client.socket().setTcpNoDelay(false);
// HERE ENDS THE GUILTY LINE
client.socket().setKeepAlive(false);
m_engine.addNewClient(client) ;
}
}
}
}
}
Does someone see what can be the reason of this ?
I made a search on newsgroups, but didnt' found any answer.
Thanks in advance,
Cam
PS : sorry for my crap english : I'm french and frenchies have never been so

- Font Faces and Styles Not SetI'd like to see if anyone can offer an explanation for some font
issues before I report the issues as bugs to Sun and Apple. Please let
me know if you can explain the following as correct behavior.
It appears to me that a lot of fonts simply don't work under Java 1.4.
The simple application below should show fonts with a normal face,
bold, italic and underline. Underline seems to work on all systems,
but on both Windows and OS/X, bold and italic fail on many fonts. The
same fonts seem to have bold and italic faces in non-Java
applications, so it appears to be a problem with the JVM. For example,
STENCIL on the Mac and Century on Windows both have distinct bold and
italic faces in Word, but not in Java.
On OS/X, many fonts do not display the proper face; they seem to
default to serif or sans serif. Most of the Lucida fonts show this
problem.

- ZoneView: does it work?I'm going to repeat a question that i've asked in javalobby to no
avail.
Did anyone ever got zoneview working for a JEditorPane and if so how?
I'm using a custom stylededitorkit that implements view factory and my
factory code looks like this:
public View create(Element elem) {
String name = elem.getName();
if (name != null) {
if (name.equals(AbstractDocument.ContentElementName)) {
return new LabelView(elem);
} else if (name.equals(AbstractDocument.ParagraphElementName)) {
return new CountingParagraphView(elem,observer);
} else if (name.equals(AbstractDocument.SectionElementName)) {
return new ZoneView(elem, View.Y_AXIS);
} else if (name.equals(StyleConstants.ComponentElementName)) {
return new ComponentView(elem);
}else if (name.equals(StyleConstants.IconElementName)) {
return new IconView(elem);
}
}
return new LabelView(elem);
}
Ignore the contngparagraph view, its just something i did to be able to
tell the amount of text visible.
Using zoneview here gives an nullpointerexception in the guts of swing,
in AsyncBoxView i think.
I'm just looking for a way not to load to the views the entire text at
a time (That is sloooow). And getting an indicator of the index of
text. I'm going to append my editor kit and textpaintobserver if you
want to see how it works (to make it work, just replace zoneview with
boxview in the method above).

- Manifest.mf Class-path troubleHi group!
I'm deploying an application with this structure
app
app/app.bat
app/lib/app.jar
app/lib/another.jar
app/plugins/other/
where the (windows) batch file starts the application like so:
java -jar lib\app.jar
and the Manifest.mf with that jar puts another jar on the classpath
like so:
Class-Path: another.jar
Now I also want to put any plugin classes that users put into
app/plugins/other/ onto the classpath, roughly like so:
Class-Path: another.jar "../plugins/other/*"
So far I've tried a few variations, but the development cycle is quite
tedious and it ain't workin yet.
I'm wondering:
* use quotes ?
* forward slashes ok on windows or do I need separate versions for Win
vs Unix ?
* end the directory with / (or resp. \) or nothing (../plugins/other) ?
* end the directory with "/*" or possibly "/*.class" ?
Alternatively I could use the java -classpath arg in the batch file,
but I've tried that and it's not working either, so I'm getting the
impression that using the Class-path: line in the manifest somehow
disables the -classpath arg of the java command. Is that so?

- Java localization on MacDear developers,
I made a Java application. I packed it as an ".app" container using Jar
Bundler, then I launched the ".app" and I saw that the standard menu
(the one with About and Quit commands) is in English and not in my
system's default language. How can I get it localized?
Thank you :)

- Pipelining COM portsIs it possible to create a pipeline to virtual COM port (MS Windows)?
I connect a mobile phone to PC over Bluetooth and
[CommPortIdentifier.getPortIdentifiers();] does not enumerate any port,
neither COM1 nor virtual port for mobile phone.
If I use [new FileOutputStream("COM10");] then I can send data to
mobile phone but I can't read the response.
Basically, I need to open a pipeline to file. Where can I find more
information on this topic?

- intersection model with threads problemX-No-Archive
Hello,
I am trying to learn java threads, and to attempt an exercise from my
textbook, hwever I am not sure if any of my proposed solutions are in
the right vein...
The problem is to model an intersection with trafficlights and 2
sensors at each trafficlight, one for arriving and entering, and one
for exiting..., and cars as threads.
the time the car stays in for, the length of time it takes the lights
to switch colors, and the number of cars must all be definable and easy
to change..
I was consiering having each car as a thread, and sensors and
trafficlights as a monitors, when a sensor detects a car arriving, it
notifies the trafficlight to change, and trafficlight will block or
allow the car thread to run, ie enter or leave...
I'm not sure if I am even on the right track, and can not find any
example solutions to this problem, so if anyone has any idea I would be
very gratefull
Thanks,
Jason

- Programming with JCo (SAP)Hi,
I hope there is someone out there with programming experiences in SAP
over Jco.
Unfortunately I have no SAP System here to test my code with.
In the documentation is written:
------
JCO.Repository mRepository;
mRepository = new JCO.Repository("ARAsoft", mConnection);
We invoke the constructor for JCO.Repository with two parameters; the
first one is an arbitrary name, the second one either a connection pool
name or a JCO.Client object. In other words: Both connection pooling and
direct connections are supported. In (web) server applications, we
should always use a connection pool for the repository. The userid used
for the repository has to have sufficient authorizations in SAP for the
metadata access to be possible. Please read the Javadoc for class
JCO.Repository to find out which specific authorizations are required.
You can use one special userid for the repository access and one or more
"normal" userids for the actual application.
------
I have the following code I was able to test on a foreign system:
public JCO.Function getFunction(String repositoryName, String
functionName,
JCO.Client connection) {
IRepository repository =
JCO.createRepository (repositoryName, connection);
IFunctionTemplate ft = repository.getFunctionTemplate (functionName);
return ft.getFunction ();
}
To create the Repository I pass an object of type JCO.Client. I have got
this object from a pool before.
When I understand the documentation corretly I can also pass the pool to
create a Repository. Then there wouldn't be no need to handle with
JCO.Client objects.
But I can not test this and thus I want ask if someone can confirm that
this works.
And another question: Since I don't need any Client objects then, I can
not release them to the pool. Is that ok and happens implicitely, or do
I have to do something else?

- help with my first project on first job, how to read a strange file, thanks a lot!!!!!!!the OS is mainly windows. i doubt windows has powerful tool to do the
job automatically.
i need to open and close the file frequently because another process
is writing to the file. then Java create a new object each time I open
the file. in this case, can the program remeber the position I set
last time?
if yes, can i do the same thing with BufferedReader class instead of
RandomAccessFile. i am not sure whether RandomAccessFile can easily
allow me to keep the new line characters and white space among the
valid text. i need these chars in the application. The length() can
not help me a lot, since the file size does not change when new text
is written into the file. the new text write over the whitespace but
do not change the file size.
thanks again!

- JavaMail GNUMail, Knife, Classpath and gnu.inetOk, here is the deal. I am trying to install a ready to go NNTP
provider for jmail. This lead me to the Knife project, which lead me to
GNU mail which lead me to Project classpath which has led me to a huge
patchwork of downloads.
Has anyone else tried to get this all working? I know for sure that the
code modules I downloaded are not compatible with eachother. One set of
code, for example, is calling on constructors and methods with wrong
method signatures.
Does anyone have something to say on this? Am I missing something? Open
Source is fairly good at avoiding this sort of thing, but then again...

- ImageIO.read(url)Hi,
I have an applet with this operation, from the Eclipse it is running without
problem.
When I upload to the web, I receive an "access denied".
Then I find that i need a signed applet. I signed the applet in a jar file,
and uploaded again.
The communication between java & javascript is working, but I continue
receiving the "access denied" error.
How can I set the security permissions to allow the applet to load the image
from an URL that is in another server ?
I need to use another object to read the image ?
Thanks to all.

Is this possible.
Any help in this matter would be highly appreciated.

- jdk 1.5 on linuxHi.
Anybody tried jdk 1.5 on linux ?
I downloaded it, but I can't use any of new features.
Example : Generics
import java.util.*;
class test {
List<String> list = new ArrayList<String>();
}
this class compile fine on jdk 1.5 on Windows, but make on error on
linux :
> ./java -version
java version "1.5.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build
1.5.0-beta-b32c)
Java HotSpot(TM) Client VM (build 1.5.0-beta-b32c, mixed mode)
> ./javac test.java
test.java:4: <identifier> expected
List<String> list = new ArrayList<String>();
^
1 error
on windows, java -version returns
C:\Documents and Settings\Mike>java -version
java version "1.5.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build
1.5.0-beta2-b51)
Java HotSpot(TM) Client VM (build 1.5.0-beta2-b51, mixed mode,
sharing)
I downloaded the 2 version (windows & linux) together.
Sun says that linux version is also a beta2 version but that's not
what "java -version" report.
So, anybody having the same problem or an idea on what happened ?
Thansk in advance.
Mike
