- 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
moves except these on combo header or outside my combo. So I cannot
choose any item from the list.
But I can use keyboard...
This is default combo, I've just create it and populate some Strings
into it.
any idea what's wrong?

- 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

- 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);
}

- Help needed (GUI/passing objects)
Hi, I'm a student learning java. In my latest assignment, I am to create a
Scheduler/Diary, with a GUI.
I am getting the error
Exception in thread "main" java.lang.NoSuchMethodError: BaseFrame: method
<init>
()V not found
at Dairy.main(Dairy.java:22)
From the main method in 'project.class', I create the diary object, which
creates month and day objects etc...
I create a state object, which takes in the Diary Object and points to the
selected month, day, appointment etc
I then create a gui object, which is to change the state (through methods in
the state).
This error occurs whenever I pass in the state object to the GUI
('BaseFrame').
Exception in thread "main" java.lang.NoSuchMethodError: BaseFrame: method
<init>
()V not found
at Dairy.main(Dairy.java:22)
I'm not sure whats causing this. I'm checking like 22 in the 'diary' class,
but it's a }. Not too helpful.
GUI appears when no state object is passed, can't manipulate the data with
that though....
In main:
------------
//set up the Diary
Diary dia = new Diary();
//set up the state
State diaryState = new State(dia);
//Set up the gui
BaseFrame firstFrame = new BaseFrame(diaryState);
---------------
When setting up the GUI:
---------------
State curState;
//constructor for the basic frame, takes in a state object
public BaseFrame(State sta)
{
curState = sta;
.....................}
--------------------------
Done a search online, didn't get too far. Any ideas? What does that error
mean exactly?

- Download a webpage that contains javascriptI am trying to download the html page at
http://www.dreamteamfc.com/dtfc04/servlet/PostPlayerList?catidx=1
Using the code
public class DownloadWebPage
{ public static void main (String[] args) throws IOException
{
URL url = new
URL("http://www.dreamteamfc.com/dtfc04/servlet/PostPlayerList?catidx=1");
BufferedReader webRead = new BufferedReader(new
InputStreamReader(url.openStream()));
String line;
while ((line = webRead.readLine()) != null)
{
System.out.println(line);
}
}
}
But all I am getting is
<HTML><HEAD><SCRIPT
LANGUAGE="JAVASCRIPT">location.replace("http://www.dreamteamfc.com");</SCRIPT></HEAD></HTML>
I'm guessing that when the web brower meets this code it executes the
javascript
location.replace("http://www.dreamteamfc.com")
And somehow loads the web page.
How do I go about downloading the actual web page that gets displayed
in a normal web browser.
Any help appeciated!

- JNI: passing Objects containing non-primitive types back and forthHi folks,
looked through a lot a threads overhere already but did not find an
answer detailed enough:
I want to map a c-structure like this created in my native code
struct mystruct {
long pid ;
long data[] ;
long meta[][] ;
} ;
to a java-object within my Java-code which would look like this IMHO:
public class ComplexData {
final int maxdata = 100 ;
final int maxmeta = 5 ;
private long pid ;
private data[] = new long[maxdata] ;
private meta[][] = new long[maxdata][maxmeta] ;
public void ComplexData() {
// Assigning values
pid = 1234 ;
data[0] = ...
}...
As far as I understood it is now possible to pass this Java-object to
the native code using the JNI-Function NewObject and read the members
and assign their values to the c-structure's members (to make them
available from within c) and the other way round, assign the values
from the c-structure to the members within the Java-object (possibly
without the initialization in the "Java-world" (I need both
directions).
My problem now is: How do I access the object's members (especially
the array types) from within c? Functions pointed to in different
threads (e.g. (Get|Set)LongArrayRegion ) need the reference to the
array, but I have only the reference to the object up to now.
Any code snippets based on the code above would be helpful.
Cheers

- 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?
arnie
*****************
/* Create 2 million Dto objects with random data and insert into HashMap

- Java encryption <--> .NET encryptionHajo,
I need to exchange encypted data between
.NET and Java environments. The first
problem I encountered is that symmetric
ciphers in .NET needs initialization
vector and Java counterparts don't.
Can some one point me out the place
where I can find any practise and
patterns for encrypted communication
between Java and .NET ?
thanks for any info

- Vetoing a change by DefaultCellEditor in JTableI'm using a DefaultCellEditor with a JTextField to capture a String
that is ultimately passed to setValueAt in my TableModel. In that
method, I have logic which could throw an exception if the String's
contents proves to be invalid (i.e. one use is where the String is a
regular expression that might be syntactically invalid).
How can I handle this? Right now, the code throws an Exception which
I'd like to catch, display a dialog, and then return the user to
editing without ever committing the value. Is this easily doable?
Regards,
Brian.

- 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

- 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,

- SET CLASSPATHhi, i'm using the abstract class definition, and when compiling the abstract
class it's ok, but the problem is when compiling the subclass: i get the
following message:
Rect.java:9: cannot resolve symbol
symbol : class GeoFigure
location: class figures.Rect
public class Rect extends GeoFigure
^
1 error
the abstract class is called: GeoFigure;
and the subclass is Rect
so how cn use the set classpath at command line, should it include the
directory where are located all the package files(the abstract class and
subclass .java files), or should it point at onel evel before the directory
that contains the package files?
thank's!

which document did you check?
Look in the API and search for mouselistener, or more generally, search for
'listener'.
Here's one to get you started
http://java.sun.com/j2se/1.4.2/docs/api/java/awt/event/MouseListener.html
there's also other "listener" interfaces and adapter classes.

Oh, my bad. Yeah, java support mouse, I just had an bad example.
How about other HID devices? Such as joysticks, drawing pen (digital
pen, etc). I know there are some thrid party library which may do some
of the work, but how about the "original" support from Sun's java?
>From my limited knowledge, I heard the HID is a special class of
devices, so I assume they may need a special library and APIs to
support them.
Thanks.

- 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]

word of more than 100 characters
int longestWord = 0;
for(int i = 0; i < lengths.length; i++) {
lengths[i] = 0;

- Trusting ceritificates where CN does not match website hostnameJDK 1.4.2_08
I am getting the following exception:

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 ??

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...

- 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
{
}
}

- 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
already looked at the Sun website, but I didn't find a URL to download
the source files from.
Kind regards,
Dirk

- show a form from anotherPlease 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.

- 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.

- Sending XML as a String through a web service (Tomcat/AXIS)?Hi, I have a web service written with Tomcat/AXIS. One of my
methods receives a String. Is it possible to send a String of
XML through this method? Will the XML tags confuse the
underlying web service system? Or will the XML be "escaped"
(with the <, > characters rewritten somehow)?
Thanks.
