- How to receive events from a jcombobox in an internal Jpanel ??Good evening,
I've a Frame with two Jpanel, in Jpanel1 I've a Jcombobox and it's
listener while in Jpanel2 I've a JLabel where I want to write the
selected value of the Jcombobox,
Jpanel1 , Jpanel2 and the main frame are in 3 separate class and files,
this because I want to arrange a modular design.
My question is how I can receive in the main Frame the event coming
from Jcombox value changed in Jpanel1 ???
Thanks for your help

- Precision problem with doubleHi everyone,
I am a Java beginner, and I am trying to create a very simple binary
tree.
Each node has a value, the left child has the same value + an
increment, the right child has the same value - the same increment.
I try to recursively create the tree, but I have precision problems.
My "main" node has a value of 10, the increment is 0.1, tree depth is
4
So i want a tree that goes like this :
depth 1 : 10
depth 2 : 0.9 / 10.1
depth 3 : 0.8 / 10 / 10 / 10.2
depth 4 : 0.7 / 0.9 / 0.9 / 10.1 / 0.9 / 10.1 / 10.1 / 10.3
But at depth 4 when I try to print the value I get 9.700000000000001
instead of 9.7, and 10.299999999999999 instead of 10.3
And things get worse when the depth increase.
All the values and increment are stored in double (native type).
Is it normal? How can I avoid this problem?
Thanks a lot,
Tom.
[main class]
double increment = 0.1;
double startValue = 10;
int maxDepth = 4;
Tree myTree = new Tree(startValue, 1);
myTree.recursivelyCreateChildren(increment, maxDepth);
[Tree.java]
public int depth;
public double value;
public Tree leftChild;
public Tree rightChild;
Tree(double value, int depth){
this.value=value;
this.depth=depth;
System.out.println("node of depth " + depth + " created, value = " +
value);
}
public void createChildren(double increment){
rightChild = new Tree(value - increment, depth+1);
leftChild = new Tree(value + increment, depth+1);
}
public void recursivelyCreateChildren(double increment, int maxDepth)
{
if (depth < maxDepth){
createChildren(increment);
leftChild.recursivelyCreateChildren(increment, maxDepth);
rightChild.recursivelyCreateChildren(increment, maxDepth);
}

- src.zip of j2ee1.4 sdkHi,
I downloaded the j2ee1.4 sdk, but I can't seem to find the source files
in that package. They used to be in a src.zip file, or not? Anyway I

- what i do wrong???Hello All!
I think I have a mistake in my logical sequence of thoughts...
When I want to take influence on my JComponents (JTextField,
JCheckBox, etc.),
do I have to place a listener within the constructor???
My problem was the following. I wanted to get the values from my
different JTextFields an write them to any *.txt file. That did only
work, when I inserted a KeyListener who registered any changes in the
text fields. But my real problem is now, to get the values back from
the *.txt file an set them with setText(String) in the text fields.
This don't work.
I have seen in the NG, that there will be oft spoken about
revalidate() or repaint(), but that don't work anyway.
It does not matter, what I want to do - set a component enabled, or
disabled or what ever, I have to have an adequate listener within the
constructor so that the changes will be visible, isn't it that way???
For example:
public void any_method()
{
myTextfield.setEnabled(false);
}
// IT DON'T WORK
// ...but I don't know why. When I put it within the constructor, it
works...
I don't know what to to. I know it from MFC, there I could get
influence on my components in any method.
I don't know what I do wrong in Java.
(My program is an application with JFrame and SWING componets. I use
JTabbedPane and for each tab a Jpanel)
There must be a simple solution for my problem (I hope so).
Please led me out from this dead-end street.
Thanks in advance

- Reference and Garbage CollectionI'm not quite sure about what kind of references to an object determine
its "alive" quality and its readiness for garbage collection. For the
moment I understand that *any* living reference, including non-explict
of member classes, keep the object alive.
Would you agree that the follwoing class "NeverRelease" entails
instances which will never get prone to garbage collection?
class NeverRelease
{
Child1 child;
public NeverRelease ()
{
child = new Child1();
}
private class Child1
{
}
}
While would you also agree that instances of the following class
"AlwaysRelease" always become garbage because the member class is static
and hence does not take reference to the enclosing class?
class AlwaysRelease
{
Child2 child;
public AlwaysRelease ()
{
child = new Child2();
}
private static class Child2
{
}
}

- performance and memory usage.
Hi
I created a test program to try the speed and size management of the JDK
HashMap. With regards to this I was wondering if anybody has any
comments on whether this is an appropriate way of testing this
performance, i.e. how realistic is the results with respect to caching
influence of data, heap management etc. The code is simple, but would it
produce a correct result. (the program finishes in 11 seconds on my
machine). the code is attached.
Secondly, I was wondering about the memory (heap) usage in java for this
program. It needs at least 256 MB of heap to run to finish. cmd:
java -Xms32m -Xmx256m -cp target/classes/ App
Using -Xmx128m causes OutOfMemoryError.
When calculating on the size of the datastructure i find approx that
2M Dto's = 16MB
2M Integer's for map key = 8MB
2M Integer's for ArrayList = 8MB
Thats a total of 32MB plus some megabytes for the objects,
datastructures, JVM and so on. So probably about 48-64MB in total.
Thats a completely different number from 128 MB or 256 MB.
Does anybody have any comments on why the program requires that much memory?

There's an easy solution to this. All the "for money" people have to do is
WRITE BETTER software...
I can't believe that projects like Eclipse are doing so well, simply because
they are OSS. It's because they are better...

- PrintServiceLookup.lookupPrintServices fails to list new printers until re-start (JDK1.4.2_03, Linux RedHat, Tomcat 4.x)Hi Forum,
How could I get
javax.print.PrintServiceLookup.lookupPrintServices(null,null) to return the
current available services while the program that uses lookupPrintServices
is running? In a tomcat servlet I use the lookupPrintServices(..) to get a
list of the printer services available. The class works well and returns the
list but if I install a new printer, the servlet does not list the newly
installed service until I restart Tomcat. Is there a way to unload and
reload the PrintServiceLookup class and then call
PrintServiceLookup.lookupPrintServices?
It appears that the lookupPrintServices(..) returns the list of services
that was available when the instance of the virtual machine was started.
Hence, while the instance is running, it allways returns the same list of
services. If I run a program that lists the services and then exits, the
program lists the newly added printer on re-run. But if the program never
exits (it runs in a loop, re-listing the services every so often), and I add
a new printer while the program is running, the newly added printer is not
listed until I terminate teh rpogram and re-start it.
Thanks in advance for your responser

- Java FACT ?"FACT: Java has no first-class functions and no macros. This results in
warped code that hacks around the problem, and as the code base grows,
it takes on a definite, ugly shape, one that's utterly unique to Java.
Lisp people can see this clear as day. So can Python folks, so can Ruby
folks. Java people flip out, and say "macros are too much power",
or "what do u mean i dont understand u" or "fuck you, you jerk,
Lisp will NEVER win". -- Steve Yegge, 2006-04-15
what would you people make of the above statement ? Has anyone here
used Lisp *and* Java on major projects ? If so would you say this
sounds off-base or correct ?
thanks,

- JComboBox strange behaviorHello!
I have interesting problem with javax.swing.JComboBox (java 1.4.2)
When I click at combo to open list - there is no reaction to mouse

But I can use keyboard...
This is default combo, I've just create it and populate some Strings

java-programmer, show a form from another
Please bear with me as I am pretty new to Java.
I am developing a Java Client application.
I have a frame with a button. When I click on the button, it hides the
current frame and opens another frame which is in another class.
When I click on a button on this second frame, I want to close it
(this.dispose) and show the first frame.
The question I have is:
From the second class frame, how do I reference the first frame?
I don't want to close the first frame as I want to keep any data entered.

- Interrupt on Java thread..I have two threads, one reading from stdin and writing to a socket
(requestThread),
one reading from a socket and writing to stdout (responseThread).
When the response thread gets a msg from server that an error occurs, it
closes the socket and calls interrupt() for it's thread group before
exiting.
But requestThread never seems to get the interrupt.
It is blocked(?) on a readLine() from the BufferedReader omn stdin.

- Hibernate and Eclipse -- where to start?Hi folks,
This began as a thread in comp.lang.java.programmer, but the focus has
really moved toward db stuff, so I repost bits here. For the full
thread, see "searching for yoda - a developer's tale" at:
http://groups-beta.google.com/group/comp.lang.java.programmer/browse_frm/thread/aa12c688b702cc72/f769b8aebe720db5?_done=%2Fgroup%2Fcomp.lang.java.programmer%2Fthreads%3Fstart%3D0%26order%3Drecent%26&_doneTitle=Back&&d#f769b8aebe720db5
[...] how to fit Hibernate into Eclipse. Again, my problem statement
is that I naturally work with objects and object graphs and would
prefer to spend most of my development effort in this domain. I would
like as much as possible to have mapping and schema handled by the
tool. It *seems* to me that the "natural" mode for Hibernate is to
start with the mapping and use the tools to generate Java and schema.
This is still better than starting with a relational model.
The learning required for these technologies is what I'm confused
about. What exactly do I need to learn? I have a couple of Hibernate
books (the "in Action" is one of them and is, so far, quite good). The
API seems reasonable and not too intimidating. If I were still a
vi/JDBC coder, I would simply add Hibernate API as a tool and
incrementally move forward. But, now that I'm a full-fledged Eclipse
user and committed to focusing on the object model, I'd like to (1)
integrate Hibernate into Eclipse (via any of the afore-mentioned
plug-ins or others), and (2) try to work from the object side of ORM.
Online docs for the plug-ins to solve (1) seem weak. It's hard to tell
which plug-in does what, and what the advantages/disadvantages of each
might be. (2) seems to imply, from my reading, a need for XDoclet or
some other Attribute-Oriented solution to bury the necessary hibernate
tags into the code. Once again, the docs I've found seem weak. More to
the point, as I've mentioned, each new link leads to five others and
their associated technology requirements...It just gets out of hand
quickly. My hope is for someone here to point the way through the fog
and say "here's how to integrate Hibernate" or perhaps "don't bother
integrating Hibernate, use this basic config file and modify as
needed", etc.
Any guidance would be greatly appreciated.

- Runtime.exec and socketsI submitted this as a bug, but no response. Can anyone help?
FULL PRODUCT VERSION :
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 2000 [Version 5.00.2195]
A DESCRIPTION OF THE PROBLEM :
Runtime.exec() to start a new java program. The new java program
should create a socket connection to another program.
The socket will connect if created and used from the static main
method. It will also work if placed in a static method called from
main. It will not work if I create an object and have the object
execute the same code (which is what I need); it fails both times if
the method is static or not static.
If I run the java program from the command line and not by using
Runtime.exec, it works beautifully.
If while it is blocking I kill the first vm, then the second vm
continues.

- Logging APIHello,
I have been using the logging API to log HTTP requests. I have an
object, which resembles a HTTP request and has methods to extract the
typical fields of a HTTP request.
Now, I have noticed that you can only pass log messages as a String and
not as an object. Also I saw that Formatters format "around" this
String. I think that is quite a limitation for my purpose.
What's if I have different Log Formats, which I would like to apply.
For example, there are different levels of verbosity. The apache log
format "combined" sends more output then "common". Maybe I also want to
define my own custom ones.
Then I would like to have a Formatter for each output Format. Do do
that, however, Formatters would have to be able to work on those HTTP
objects, which contain the fields.
That does not seem to be possible under the current logging API or am I
missing someting here? I really don't understand, why the message is
not being stored as an Object but a String - that only limits the use
of the Formatter.
Can somebody elaborate on this. Maybe it should be brought up with Sun?

- JSP vs XSLT?Which is better JSP or XSLT? I prefer JSP for two reasons performance
and less complicated to learn.
JSPs are compiled one time, then cached, unless the code changes. This
not the case with XSLT, as I understand it.
XSLT is very complicated to learn, in my opinion.
See this article by IBM on JSP vs XSLT:

I have imported the certificate into the cacerts file via keytool -import.
However, my problem is that, the operator has setup a development and
production website, where the hostname naturally differs ... but both
development and production URLs have the same certificate.
That is, the production, Verisign-signed server certificate is the same
certificate on the development website. This ceritificate, therefore, has
the common-name ( CN ) set to the hostname of the production website.
Thus, even if I import the certificate into the cacerts file, because the
server certificate' CN does not match hostname of the website, I get the
exception above when connecting to their development website.
Apart from implementing DummyTrustManager as per this article:
http://www.javaworld.com/javatips/jw-javatip115.html
... which I'd rather not, is there any other workaround ??

- i18n in Swing, trouble.Hi,
I am building my first Gui with Swing, and in the same time I need to
use the i18n to make it work in Japanese and English.
I use Eclipse and its great Visual Editor to save time, all my files are
utf8 encoded. And, I am under WinXp...
My trouble is the following :
-> If I make a jMenu with some japanese hardcoded text, it appears fine
in my application.
-> If I use a ResourceBundle to get the text, I have garbage. I use the
following line: myMenu.setText(myBundleResource.getString("myTest"));
The .properties files for the japanese is also in Utf8
Do you have any idea why the text in the .properties file is not passed
correctly ? Any help would be really appreciated.

- Creating HTML files from Java accessing OracleHello folks,
I have some queries that folks would like to have as HTML reports. At
first I tried Oracle Reports but it's HTML output seems really poor
and not 508 compliant which is an issue for us. I'd like to use JAVA
(I use Jdev as my IDE right now.) but was hoping someone might have
some insight on the best way to tackle this. I guess I am looking for
methods that would make things easier rather than just outputting
print commands line by line. :)
Thanks folks...

- Extending the code
I have the following code but i want to add a function which will allow
me to count the number of vowels in the text file. I was wondering if
anyone would be willing to give me some help with this
[CODE]
import java.io.*;
import java.util.*;
public class App {
//Create BufferedReader class instance
public static InputStreamReader input = new
InputStreamReader(System.in);
public static BufferedReader keyboardInput = new BufferedReader
(input);
public static void main(String[] args) {
int[] lengths = new int[100]; //Runtime error if the file contains a
word of more than 100 characters
int longestWord = 0;
for(int i = 0; i < lengths.length; i++) {
lengths[i] = 0;
}
try {
System.out.println("Enter the name of the file you wish to read:
");
String fileName = keyboardInput.readLine();
FileReader file = new FileReader(new File(fileName));
BufferedReader myFile = new BufferedReader(file);
int numTokens = 0;
int numWords = 0;
int numChar= 0;
String line;
while ((line = myFile.readLine()) != null ) {
String[] words = line.split(" ");
numWords = numWords + words.length;
for (int i = 0; i < words.length;i++) {
numChar = numChar + words[i].length();
if(words[i].length() > longestWord) {
longestWord = words[i].length();
}
lengths[words[i].length()] = lengths[words[i].length()] + 1;
}
}
System.out.println("\nThere are " + numWords + " words in the text
file");
System.out.println("\nThere are " + numChar + " characters in the
text file");
System.out.println("\nThere length frequency of the words is as
follows:");
System.out.println("\nLength : Frequency ");
for(int i = 0; i <= longestWord; i++) { //Print frequencies only up
to the longest word
System.out.println(i + " :"+lengths[i]);
}
myFile.close();
}
catch(IOException iO) {
iO.printStackTrace();
}
}
}

See http://www.well.com/user/xanthian/java/TravellerDoc.html ;
sadly that links to a jar file containing a version about
1/3rd the size of the one I'm running now, which contains a lot
more featuritus captured as Java, but is nowhere near ready to
publish. If you want a "warts and all" copy of the current work
in progress, I can send one to you by email.
> OH MY GOD, KENT IS ACTUALLY ZZ TOP
> BASSIST DUSTY HILL!!!!!:
Funny you should say that. When I was
courting my current wife, she showed the
secretaries working for her a picture of
me, with an earlier incarnation of the
same beard (this was 1991) , and to a
one they responded: "You're marrying ZZ
Top!?!" I was a lot cuter then.

Posting unworkable URLs doesn't much
help. In anycities rabid insistance
that you get a chance to read one of
their misleading and deceptive "improve
your website" ads, before seeing
anything useful, they disable direct
access to anything that isn't an HTML
file they can corrupt.
To see the above picture thus takes
two steps:
Click here:
http://www.anycities.com/user/xanthian/KentImages/KentImages.html
Then choose the top link "this" to see
the above picture. If you look at some
of the others, you'll notice I've added
a bit of fur.
> TELL ME WITH A STRAIGHT FACE YOU CAN
> TELL THE DIFFERENCE!!!!!!!!
How to tell it's Dusty and not Kent the
man from xanth:
1) Dusty still has a lot of orange color
in the sides of his beard; mine is snow
white except for a score of black hairs
in my moustache.
2) No time in my entire life have I had
a babe like that on my arm, counting two
wives and a daughter all in wedding gowns.
> HE'S BAD, HE'S NATIONWIDE!!!!!!!!!!!!!!!!!!!!!
Worldwide actually, but hardly
admirable.
xanthian, the homelier twin.
