- Any HID support for Java?Human Interface Device (mouse, etc)
Does anyone know whether java support the HID devices? (under MS
Windows)
I checked the document but did not see any. A google on this group
also returns little information.
Thanks a lot.

- 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

- 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

- 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?

- 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?

Brian.

- 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?

- 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);
}

- 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?

- 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
{
}
}

- 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,

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...

that sounds as if you thought that people have a moral right to be paid as
programmers. (?) why is it more villainous to make it difficult for someone
to get paid as a programmer than to expect people to pay you for something
that someone else would give them for free?

so giving away things out of generosity or a feeling of reciprocation is
wrong and makes someone a villain, but giving them away out of greed and in
the hope of making people pay for them in indirect ways is good and
laudable?

That is not the point. The point is that programmers with
too much free time are ruining other peoples' business.
This kind of thing can only happen in the software-industry
because all it takes to create (or better to say in this
context, copy) software is time (and expertise).
But, imagine this ; if some really, really rich person would start
creating cars which are almost identical as some existing brand
(for example, the Volkswagen Beetle) and would give them away
for free ?
This would obviously damage Volkswagen which has invested
a lot of money and time in developing this car in the first
place. This would be considered 'really unfair business'.
With software, this is no different. These OSS guys which
all are working on free versions of existing software are
ruining it all for programmers who actually DO HAVE a job.

Most are employed in large businesses and institutions that have a need for
better quality software...which is why they write it.
Necessity is the Mother of Invention.

B.S. Writing good software is magic -- as magic as making music. Some can
create perfect programs, that are dry and never get used. Others throw
together the barest essentials, and yet garner great acceptance.

Look -- for most middle class and above people, goods are essentially
'free'. THey are free in the sense that the burden of buying a car is no
longer something unbearable. Families can buy and replace cars easily.

Well, as in software, you just don't take a lot of money and do such things.
The De Lorean is an example. This person got all the money and funding and
resources and design and yet could not produce a car that people would
want.

Most programmers are not writing or selling office suites.

You seem to be muddling two issues together here. One
is the issue of the cost of products. The other is the
issue of using other people's designs and ideas.
Are you suggesting free software is more prone to
copying the ideas of others than any other sort of
software is? If so, what evidence is there for that?
There /is/ a set of laws that prevent large powerful
agents from putting other companies out of business
by giving away goods that compete with their products.
These laws are anti-monopoly laws - and are there
to prevent organisations attaining dominant positions
- or extending existing dominant positions into
adjacent areas.
It is quite a strained analogy to think that these
apply to the distributors of most free software.
Those laws may have applied to Microsoft when
distributing IE free of charge, though.

Not all OSS programmer work in their 'free time'. And if your programs
aren't worth buying, no one will buy them, regardless of any free programs
others may create.

Why do you assume that they don't have jobs either? Or that they'll all
working on free versions of existing software? Or, indeed, that they don't
have the right to create software for free? Or that the world owes
*anyone* a living?

If they were doing that with the intent of creating and cashing in on
a monopoly, then that would be bad. I see nothing wrong with doing so
pro bono publico. I've been programming for decades, and what I see as
bad is software that is distributed without source code, whether or
not I have to pay for it. Was it evil that programmers in the 1950s
and 1960s routinely exchanged code in order to save effort?

As long as he did not use that as a way of creating a monopoly, I see
nothing wrong with it.

Only if he started charging after he had driven out the competition.

Hogwash; at worst they are ruining it for greedy corporations. Most
programmers are involved in writing software tailored to the needs of
their employers, not in writing general purpose software.

No. I use "free" software extensively. Yet I also have a job
programming.
Please let me know when OSS comes up with free air-traffic control
facility software. Our clients would be interested.

Well, you can only hope that the demand for your company's software
is not big enough to make it 'worthwile' to create a free version.
But if some twisted mind decides to create air-traffic control software
with some help of his air-trafic-buddies and then starts to give it away
for free, then what ?..
Then your company would probably go bankrupt.

That's what tends to happen in a capalist economy where a competitor
develops a good product at a lower cost - and the company facing that
competition is too inflexible to either reduce their own prices or move
on to another market.
Historically, software has been a lucrative market place, with lots
of money to be made in it. I should think there's not much need to
bitch about those pitching ultra-low cost products into the market,
in the hope of finding a foothold.

Most of the time yes, with regards to products! Giving things away "out of
greed" is how employees get paid, how the economy does well, and when the
economy does well fewer people die or do without. It's true: More people
get health coverage, more kids eat better, more children get braces, etc.

Hey, I like that. What's more, it can be boiled down to a nice little
slogan:
"Open Source Software Hurts People"
Neat, innit?
Of course, you can count on the same firms who make good money by
(rightfully) exploiting the capitalist market system to be the biggest
whiners when they are undercut by the competition.

Economic dislocations happen. Nobody gets rich selling buggy whips
since the automobile came along. Should they? Should we pass a law that
a certain percentage of profits from auto sales go to the buggy whip
manufacturers?

Perhaps this qualitative difference has some implications for what
economic models suit the field best?
Hollywood was absolutely terrified of VCRs when they first came out,
insisting that if they weren't suppressed then the entertainment
industry would collapse. Now, VHS movies and DVDs make more money
than box office receipts.
There are ways to make money off of software with open source,
but they are different from the current standard way:

If the pro version isn't better than the free version - better
enough to justify paying for it - then why does it deserve money
at all?

So? That's the whole POINT of the market. Even with perfect
competition, unmolested either by monopolies or governmental interference
there will be winners and losers. Eventually, even the best mousetrap
will become a commodity.
This process is really the whole point of capitalism and one of
the primary mechanisms through which capitalist societies build their
wealth.

They're just whining about one form of open competition. It's
fine for the 800lb gorilla to undermine companies and their business
model but it's not allowable for smaller entities to do likewise.

The diesel locomotive ruined the jobs of the firemen on coal-fired
locomotives. If your job is endangered by free software, you may
wish to find a different job.

Why would I "hope"? If I were boss, I'd be thinking of that
possibility, and prepare for it.
Of course, your idea of prep might be to start lobbying Congress to pass
laws against OSS.

Nah. There's always more work to do.
Even if all software packages were covered by OSS, we would still have
to do configuration, QA, testing, installations, documentation, software
customization, and so on.
And new software ideas would come forward that haven't yet been covered
by OSS.

I don't believe any of this would have happened had companies like
Borland or Microsoft not gone overboard and tried to get $1000 for
development suites.
Had they charged $50-$100 we might all be using their tools today.
I still pay for software in cases where there are free alternatives but
I doubt I'd pay more than $40-$50 for it. For me, if a piece of
software costs $50 I will still consider it against open source
alternatives on the basis of features, not price.
When the choice is $500+ for JBuilder, or $0 for a fully functional
environment like eclipse, I'm not going to worry about weighing feature
lists. Whatever JBuilder has that eclipse doesn't can't be worth $500.

- 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.

- Trusting ceritificates where CN does not match website hostnameJDK 1.4.2_08
I am getting the following exception:
javax.net.ssl.SSLHandshakeException:
sun.security.validator.ValidatorException: No trusted certificate found
at com.sun.net.ssl.internal.ssl.BaseSSLSocketImpl.a(DashoA12275)
at com.sun.net.ssl.internal.ssl.SSLSocketImpl.a(DashoA12275)

at
org.apache.axis.components.net.JSSESocketFactory.create(JSSESocketFactory.java:224)
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 ??

- 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();
}
}

- 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:

- 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

- 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...

- 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.

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.

- 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.
