- How to define a default font for JLabel or whole program?I don't really like how Java2 default font is bold. I think the plain
looks much better.
How can I set the default font for a JLabel or for the whole program.
I would like to change it from BOLD to PLAIN.
About half of my JLabels in my program are anonymous. It would quite a
pain to go and define a bunch of new JLabels, then change the font to
plain.

Wholesale buy cigarets online sales to retail buyers continue to
increase in the United States. Ever wonder why buy cigarets online
cost so much in the USA? buy cigarets online taxes imposed by federal,
state, and local governments, account for most of the cost of
cigarettes in the USA. New York City cigarette smokers pay some of the
highest taxes in the USA. A package of cigarettes in the City of New
York is burdened with $0.39 in federal excise tax, $1.50 in state tax,
and another $1.50 in city tax.
Online discount cigarettes has become a catchphrase amon
Next, let's examine the economic and public finance implications of
higher cigarette prices. For starters, more than half of any price
increases will be paid by smokers with annual incomes under $30,000;
only 1 percent will be paid by smokers earning more than $100,000. In
other words, cigarettes surcharges are brutally regressive; they
represent a wealth transfer from generally poor smokers to more
affluent non-smokers. If prices rise by $2.00 per pack, a two-pack-a-
day smoker will be hit with $1,460 in added expense each year. That's
an enormous burden for a low-income consumer.
g the patrons of premium brands such as Marlboro, Newport, Doral,
Parliament, Camel and Barclay. With the advent of discount cigarettes,
one can now enjoy their favorite brand at a much lower cost. Websites
displaying the "buy cigarets online" tag offer a variety of premium
and generic cigarette brands at heavily discounted prices, owing to
the tax exemption that online sales enjoy. However, "buy cigarets
online" websites desist from supplying cigarettes to some states
because of the strict laws that have been applied to online sales.

- enterprise beans - inter bean dependenciesHi,
I am using JBoss and an entity bean which caches data and is dependent
on another entity bean's cache.
The caches are built within the constructor.
How do I ensure one entity bean has been created - before I call it
with the other entity bean?
Or does this just happen by default with the home find method?

- null pointer exception while using arraysNot sure why this code doesn't work, keep getting null pointer
exception problem.
Array_test is a class that has variables of type array, boolean,
String. The idea is to have an array of Array_test objects from which I
can add and delete objects but where all the objects are stored at the
very start with no ull spaces.
Am I wrong in assuming that having null spaces in an array with a class
of type that you have implemented is okay?
Anywho here's the code, and at the end are some tests and results from
the main.
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
// For the app only one instance of Trackeris created, it keeps track
of all segs that are created
public class Tracker {
// Tracker has just one variable that's an array of objects
of type Array_test class which is predefined
private Array_test segholder[];
// construct.
public Tracker(int size_of_array){
segholder = new Array_test[size_of_array];
}
// retrive from array at i position
public Array_test getElementFromArray(int element_location) {
return segholder[element_location];
}
// retrive from array at i position
public String getElementFromArrayName(int element_location) {
String its_name;
its_name = segholder[element_location].getIdentifier();
return its_name;
}
// adds a object type array_test to the first null position in the
array segholder
public void addToArray(Array_test new_seg) {
int i = 0;
while ( i < (segholder.length - 1) ) {
if (segholder[i] == null){
segholder[i] = new_seg;
i = segholder.length;
}
i++;
}
}
// delete from an array
public void deleteFromArray(String old_seg) {
int i = 0;
while (i < segholder.length) {
if (segholder[i].getIdentifier() == old_seg) {
segholder[i] = null;
i = segholder.length;
}
i++;
}
// now remove the null space
String[] remove = {null};
List templist = new ArrayList(Arrays.asList(segholder));
templist.removeAll(new ArrayList(Arrays.asList(remove)));
segholder = (Array_test[]) templist.toArray(new Array_test[1000 -
templist.size()]);
}
}
**********MAIN********
Array_test o1 = new arrray_test("o1", 50);
Array_test o2 = new arrray_test("o2", 50);
Array_test o3 = new arrray_test("o3", 50);
Array_test o4 = new arrray_test("o4", 50);
Array_test o5 = new arrray_test("o5", 50);
Array_test o6 = new arrray_test("o6", 50);
track.addToArray(o1);
track.addToArray(o2);
track.addToArray(o3);
track.addToArray(o4);
track.addToArray(o5);
track.addToArray(o6);
System.out.println(track.getElementFromArrayName(0));
System.out.println(track.getElementFromArrayName(1));
System.out.println(track.getElementFromArrayName(2));
System.out.println(track.getElementFromArrayName(3));
System.out.println(track.getElementFromArrayName(4));
System.out.println(track.getElementFromArrayName(5));
Result, works as expected:
o1
o2
o3
o4
o5
o6
add this next line and get null pointer exception
System.out.println(track.getElementFromArrayName(6));
The delete function works fine... until I put it into a GUI listener,
then I get the same exception
Could SOMEONE please explain to me what is happening and why.
Cheers,

- J2ME HTTP Post Method ProblemHello,
I built a midlet that sends an information by POST method in HTTP
connection.
in the emulators (such as Nokia 6270,6230, 6230i..) I See the "post
data" in the diagnostic, but the data doesn't arrive to the server. I
tried several servers and they didn't work. I tried to run the SDK's on
different computers and it was the same.
If I run my midlet on my Cellphone (6230) everything works fine.
Example for the post data:
action=Login&Username=tony&password=1234
is a known problem?
Any suggestions on how to solve it ?
Here is additional information:
My J2ME Code:
String params = new String("action=Login&username=&password=");
httpConn = (HttpConnection)Connector.open(url, Connector.READ_WRITE );
httpConn.setRequestMethod(HttpConnection.POST);
httpConn.setRequestProperty("Content-Type", "text/plain");
os = httpConn.openOutputStream();
byte postmsg[] = params.getBytes();
for(int i=0;i<postmsg.length;i++) {
os.write(postmsg[i]);
}
os.flush();
StringBuffer sb = new StringBuffer();
is = httpConn.openDataInputStream();
int chr;
while ((chr = is.read()) != -1) {
sb.append((char) chr);
}
response = new String(sb.toString().getBytes(),"UTF-8");
Here is Simple PHP file which is on the server:
<?php
header('Content-type: text/plain');
if ($_POST["action"]=="Login") {
if($_POST["username"]=='tony') {
echo "<?xml version=\"1.0\"?>\n";
echo "<dictionary>\n";
echo "<Status>1</Status>\n";
echo "<Reason>0</Reason>\n";
echo "<Key>JFKDL54GFDYU85T43NJKGH89N543KGFD</Key>\n";
echo "</dictionary>\n";
exit;
}
else {
echo "<?xml version=\"1.0\"?>\n";
echo "<dictionary>\n";
echo "<Status>0</Status>\n";
echo "<Reason>Wrong Username</Reason>\n";
echo "</dictionary>\n";
exit;
}
}
echo "Not Good!";
?>
When I run the midlet on my cellphone, the server recognize the value
of $_POST["action"]
but when I run the midlet on the emulators, the server doesn't
recognize the value of $_POST["action"]. in other words, the server
doesn't get the string.
But, when I look in the Diagnostic of the emulator I see that the data
were sent.
Here is the log of the Request operation:

- java applet screenshotdear experts,
i am wondering if this simple screenshot.java program, developed by
Marco Schmidt could be ported as a applet?
I would like to port such a program as an applet i.e. take a
screenshot of the web user's browser's front window, get the picture
transferred and written on the server side and email the resulting
image back to the web user. My aim is also that all the whole process
remains painless for the user.
My question: do you know if such an implementation the current program
is possible? Is it possible to send the BufferedImage image =
robot.createScreenCapture() and write it on the server side? Would any
restrictions occur, or certificate need to be established?
You would save me all a lot of time if you could answer the question.
for a complete link to the following code, please take a look at:
http://www.geocities.com/marcoschmidt.geo/java-save-screenshot.html
/*

// a waiting period and a file name
if (args.length != 2) {
System.err.println("Usage: java Screenshot " +
"WAITSECONDS OUTFILE.png");
System.exit(1);
}
// check if file name is valid
String outFileName = args[1];
if (!outFileName.toLowerCase().endsWith(".png")) {
System.err.println("Error: output file name

"end with \".png\".");
System.exit(1);
}
// wait for a user-specified time
try {
long time = Long.parseLong(args[0]) * 1000L;
System.out.println("Waiting " + (time / 1000L)
+
" second(s)...");
Thread.sleep(time);
} catch(NumberFormatException nfe) {
System.err.println(args[0] + " does not seem
to be a " +
"valid number of seconds.");
System.exit(1);
}
// determine current screen size

Dimension screenSize = toolkit.getScreenSize();
Rectangle screenRect = new Rectangle(screenSize);
// create screen shot
Robot robot = new Robot();

- Is delegation just a route to obfuscation?I've fallen in to a pattern of what feels like excessive delegation,
probably helped along academically.
Has anyone got any wise words on detecting when it is appropriate and when
it isn't? I'm aware of responsibility. It's just that the request usually
comes from one end of the application and the ultimate responsibility is at
the other!! And then you get code which is 90% passing the buck!

- XML inputstreamI have used the SAXparser to read XML into a class using
parse(java.io.File f, DefaultHandler dh)
Now I want something different, I want to pass the XML directly, without
a file. I found that I have to use parse(java.io.InputStream is,
DefaultHandler dh) instead. My problem is, how do I generate the
InputStream, since I can only read from an InputStream? How can I have
my class generating an InputStream for the parser?

- Front EndWe have a large application running over a network environment using RMI
as commnuication between the front-end GUI and the backend server
(primarily database activity). All the Java code also resides on the
same machine as the "backend" server. On occassion software updates are
required on this backend to add new features.
What I want to do is : When users log on or connect to a network (lets
consider a LAN or VPN at this point instead of the internet), how can I
ensure that the user on a remote machine will always have the latest
programs without the need to upgrade their machine each time a software
update is done on the server.
I want to only install the minimal files on the client machine in order
to connect to and run the GUI front end. I don't want to install the
required JRE either, the required code should come from the server.
Now, I know browsers can do something like what I am thinking about when
an applet is embedded with the HTML code. That is, it will bring across
the required Java classes. But Java is still required on the client machine.
Any suggestions?

- Java data objects to XMLI am trying to figure out a *smart* way of generating XML documents from
custom data objects. Of course, to be able to apply different XSLTs in the
presentation layer.
The custom data objects will be JavaBeans with attributes and/or collections
of other JavaBeans.
One way would be to create specific converter classes with hard coded XML
tags for each JavaBean that needs to be converted but that isn't very
maintainable. Changes in data objects require changes in the converter
classes.
I see two possibilities:
1. Having a more general converter that is able to convert data objects
according to some DTDs. DTDs could be used for mapping between the data
objects and wanted XML document.
2. Using some open source framework, Quick seems to be suitable.
http://qare.sourceforge.net/web/2001-12/products/quick/
Have any of you solved this problem previously?

java-programmer, Making Internet Dialer
Greetings;
I am trying to build a windows internet dialer... I have gained
control of my modem through javax.comm API and I can dial a number
through my modem... the problem is I can not figure out how to pass
the username and password to my ISP.
I want to know what steps are involved in getting connected to my
isp... and also I want my windows O/S to know that i am connected.
Any resource given will be helpful.
I hope someone can help me in this regard.
Thanks

Usually, ISP send a "Login:" or "Username:" line and expect you to send
you rusername followed by ?^M ?(carriage return, '\r').
Then comes the password. Then comes a PPP connection. PPP is a complex
protocol with subprotocol for authentification. Then comes the IP
protocol.
All of the above are not available in je JDK, you have to use the
windows API to dial a number. It's called RAS, for Remote Access
Service. Goto msdn.micorosoft.com to learn more, but believe me: it's
awful.

Don't dismiss this too quickly -- it _is_ possible.
The best way to "implement" this is to use a dial-up package that will
automatically connect to the net whenever a network request is made. I
thought that recent Windows versions had something like this built-in
(dial on demand), but it's available for other OSs as well.
It's obviously a native solution, but you can take advantage of it in
Java. If you can't determine the local IP address (or if the only
available one is 127.x.x.x), then you can try repeatibly connecting to a
known host for a given amount of time. If you're not connected, the
dial-on-demand will connect you, and your Java program can be made to
"wakeup" wheneverthe known host connection is established.
Now if the OP wants to create their own dialler /interface/, they're
going to need to either use JNI, or they're going to have to make calls
to command-line driven dialup applications (such as the ones available
on Linux/UNIX/*BSD and OS/2) using one of Java's process launching routines.

- Removing Item From JList - getSelectedIndex problemHi all,
I am currently working on a JList that populates data into a JList
from a CSV file. I have a button that is supposed to get the Selected
index and then delete that item from the JList. Below is the code that
I am using:
int index = lstComputerExceptions.getSelectedIndex();
System.out.println("index is: " + index);
model.remove(0);
int size = model.getSize();
if (size == 0) { //Nobody's left, disable firing.
btnDelete.setEnabled(false);
} else { //Select an index.
if (index == model.getSize()) {
//removed item in last position
index--;
}
lstComputerExceptions.setSelectedIndex(index);
lstComputerExceptions.ensureIndexIsVisible(index);
}
I have printed out what index is and no matter what item I have in the
Jlist I have selected it will always print out
-1. Therefore keeps on causing my program to crash and not delete the
item out of the Jlist.
Any help in this matter would be highly appreicated.
Thank you

- newbie java/OOP questionPerhaps someone here can help me with this, I tried asking someone else
about this but couldn't quite describe my question.
I understand that this syntax calls a method on behalf of an object:
b1.method();
but in some java example code I see stuff like this (from a link list app) :
answer.head = IntNode.listCopy(head);
I know that "head" is an instance variable of the class, specfically an
IntNode. I also know that "answer" is a method variable of the type
IntLinkedBag.
My question is: what the heck is going on during the "answer.head"
operation? I don't understand how answer is interacting with head.
They're just two objects. What does the period do when it connects two
objects?
Any pointers or keywords to look up would be apprecited.

I am a naive JAVA user. Can you please tell me, oh how to implement
the following scenario
A

/ \
B C
^ ^
\ /
D
Classes B and C extends class A, but how to define class D, such that
members of both B and C are available to D.
Thanks

- Doubt regarding InterfacesThanks everyone for your replies!
I have a basic question - in the above instance Runnable is an
interface and interfaces cannot be instantiated. So something like 'new
Runnable()' seems puzzling to me. Is this syntax for instantiating an
object of the Anonymous class?
Also, is the above snippet similar to the following in the end result:
class ac implements Runnable{
public void run() {
System.out.println("Hello World on " +
Thread.currentThread());
}
};
ac doHelloWorld = new ac();
