- Text not displayed in applet under Windows XPHi all,
I'm working on an application/applet that runs fine as an application
or applet in Linux and as an application in Windows (XP), but when run
as an applet (under firefox or IE) it will SOMETIMES (not always) fail
to display text and images. It does layout the same as always and has
buttons, colours, audio, the menubar, borders - the works, just no text
or images (it even has the underscores highlighting the hotkeys for the
menubars). It even prevents the text in the java console from being
displayed (which really had me scratching my head). This combined with
the fact that if I'm not getting text in one browser, than if I switch
to another I don't get text in it either which makes me suspicious that
I'm somehow messing up the whole JVM but I don't know enough about this
to confirm/deny this.
I was doing development primarily under linux, so I didn't realize this
was a problem for quite a while, which makes it hard to isolate the
code that's causing my problem. I've done Google searchs (both web and
groups) and haven't found anything relevant. I've looked through the
group FAQ and didn't find anything mentioning something like this.
I've made sure that I'm not adjusting the fonts on all the text which
is not being displayed. I've upgraded the jre from 1.4.2_5 to 1.4.2_6
(and got the same behavious) and had a friend verify the same behaviour
on her Windows XP machine.
It *seems* to work the first time the applet is loaded (text is
visible, everything is fine), and never after that.
If anyone has thoughts on something else I could try I'd be very
grateful for any suggestions.
Thanks for your consideration,
John

- Sharing objects between class-loader instancesThere is a long discussion on the possibility (or impossibility) of
sharing objects between Applet class-loader instances (in the context
of native library access from applets) at:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4225434
In a recent project I came across this problem and came up with this
solution:
http://tom.conjective.ch/tomtom/space/Sharing+Java+objects+between+class+loader+instances
I don't consider it nice or clean. But it is certainly functional. Some
people would consider it a security hole (I guess even I, depending on
the point of view).

- Get external (public) IP from my Linksys routerI've been searching for a way to programtically get my public IP from my
router. After much research th eonly thing I came up with was going to a
site like privacy.net and returning the value it reads. What I'd like to do
is compile this into my .chm I give my remote users. So ideally they would
have a button to press that goes to the web site reads the site and returns
the ip to a text box.
I'd like to do it without the user actually seeing IE open the web site. Any
leads?

I may be missing your point here, but I think that without synchronisation,
there is no such guarantee. As it happens I've just written a passage in
another post which fits just as well here. Apologies to anyone who sees it
twice ;-)
This is discussed in the Java Memory Model JSR, see:
http://www.cs.umd.edu/~pugh/java/memoryModel/PublicReview.pdf
Two threads, two shared variables A and B, two passages of code that access
them without synchronisation:
Initially A == B == 0
Thread 1:
r2 = A;
B = 1;
Thread 2:
r1 = B;
A = 2;
A legal result of this is that r2 == 2 and r1 == 1. The JSR describes this as
"surprising behavoir". Which is a classic bit of understatement...

- problem with java version "1.4.1_01"Hello
I have installed JDK, but I am unable to use IDE's like Forte v 2.0 and Java
Workshop v 3.0
with this JDK. The problem with both is *jvm.dll*. Both software searches
for this file in my

- Digitally signing a J2ME application so that it runs in Operator domainWe are supplying a J2ME (Java) application to a mobile network
operator. We need it to be digitally signed so that it runs in the
Operator domain (as opposed to the Trusted Third Party, Manufacturer
or Untrusted domains). Can someone tell me the process for doing
this?
If there is a seperate process for each phone manufacturer, has anyone
gone through this process with Motorola, SonyEricsson or Nokia? What
are the details?
If the mobile operator needs to perform the process, that is fine, but
I still need to understand what they need to do.
Thanks.

- JTable - DefaultTableModelHello,
I have a JTable with a DefaultTableModel. I have a search Methode which
searches in the database and displays the results in the JTable. Now I
want to extract the search from the class and put it in an extra class.
I have for both the JTable and the DefaultTableModel defined getters
and setters and now I want to write the following code in the
outsourced method:
Search.getTable().setVisible(true);
search.getModel().addRow(new Object[]{name,text});
Search is the class where the JTable and the DefaultTableModel is
defined. Both lines are in a loop of a Vector size and the data of the
vector are in the name and text parameters of the addRow Method. The
problem is that this does not work and the rows are not displayed when
I start my Java Application. When I put this code (without the Search
prefix and the get-Method) it works without problems.
Is it not possible to address the table and the model in that way from
another class?

- How to pass an Array Attention Eric SosmanOne problem that I see is with the following.
for(int i = 0; i<len; i++)
{ a[i] = rand.nextInt(); // fill array with random num
System.out.println("a[" + i + "] = " + a[i]);}
return a;
}
The elements of an int array are initialized to 0. Because you have the
System.out.println and return statement within the body of the for
loop, the 1st element of the array will be set to a random int, and
then the array will be returned. When a return statement is executed,
the method exits at that point and nothing else in the method is
executed.

- M.I'5-Pers ecution ` hara ssment at w ork-=-=-=-=-=-=-=-=-=-=-=-=
-= harassment. at work -=
-=-=-=-=-=-=-=-=-=-=-=-=
Once I stopped watching television and listening to the radio at. the end of
1990, "they" had to find other ways of committing abuses. So they. took what
must be for them a tried and tested route; they. get at you by subversion of
those around. you. Since they wouldn't be able to do that with my family or
friends, that. meant getting at people in the workplace to be their
mouthpieces and do their dirty. work for them.
They supplied my employers in. Oxford with details from what was going on in
my private life, and what I and other people had said at my home. and
accommodation in Oxford.. So people at work repeated verbatim words which
had been said in my home, and repeated what I'd been. doing recently. Often
the most trivial things, the. ones from your domestic life, are the ones
which hurt most. One manager in particular at Oxford continuously. abused me
for ten months with verbal. sexual abuse, swearing, and threats to terminate
my employment. After ten months I was forced to seek psychiatric help. and
start taking medication, and was. away from work for two months. I spoke
later with a solicitor about what had happened at that. company; he advised
it was only possible to take action if you had left the company as a. result
of harassment, and such an action would have to be started. very soon after
leaving.
Over a. year later the same manager picked on another new worker, with even
more serious results; that. employee tried to commit suicide with an
overdose as a result of the ill-treatment, and was forced. to leave his job.
But he didn't take. action against the company, either. Abuse at work is
comparable to that elsewhere in that tangible evidence is. difficult to
produce, and the abusers will always have their denials ready. when
challenged. And even. if a court accepts what you say happened, it still
remains to prove that abuse causes the type of breakdown. I had at the end
of 1992. In a recent case before a British court, a former member. of the
Army brought a case against others. who had maltreated him ten years
previously.. Although the court accepted that abuse had occurred, it did not
agree that depressive illness. necessarily followed, and denied justice to
the. plaintiff.

- TCHAR in c++ to string in javaHi-
I am developing file transfer application, the host is in c++ and the
client is in java. In c++ I am using win32_find_data to get all the
files list and i am sending it to the client through the stream.
The client will reads all the specified information, but i am getting
some blocks in the middle, I hope the problem will be at the reading
side. The host will sends the data in form of win32_find_data format,
and here i am reading the information, so i want how to process the
fileName which is the field of the structure win32_find_data, at the
client side (java side), should i use the charsetdecoder to convert the
type TCHAR(fileName) data to string at java???
Thanks in advance,

java-programmer, PKCS#10 support in Java.
Hello
I am looking for some opensource Java library supporting PKCS#10 standard,
creating certificate signing request and processing answer from CA. I've
found Bouncycastle library, but it would be good to have support only for
PKCS#10, without other aspects of PKI. Do you know anything about such library?

- 2D drawing library / painting programHi,
Does anyone know a good 2D painting program in Java with source? I
have to make a "conferance room" in Java where users can draw on a
shared whiteboard that they all can see. They have to be able to write
on it, draw rects, circles, freehand, fill with color, choose drawing
color etc. like the basic things you can do in any simple painting
programs like MS Paint. Im developing in JDK 1.4 so Java 2D is
available.

- 1.5 ignoring networkaddress.cache property?I've noticed that 1.5 seems to be ignoring the value set for
networkaddress.cache.negative.ttl in
$JAVA_HOME/jre/lib/security/java.policy when a DNS request times out.
In one of my forms I validate user-provided URLs by trying to fetch them
and ensuring I get a reasonable response (e.g., not 404, 403, 500, etc).
If the DNS request for the hostname in the URL times out once, the JRE
never tries a lookup again. I've verified that it isn't asking by
snooping DNS traffic on my loopback with tcpdump.
Positive lookups do cache properly. Negative lookups that *don't* time
out (ie, they get an NXDOMAIN response) also seem to obey the
networkaddress.cache.negative.ttl property.
So the behaviour seems to be that a DNS timeout is cached forever, whereas
postive or negative responses are cached according to
networkaddress.cache.*.

- Simple GUI application attempted.Some assistance in the development of a simple GUI application would
be appreciated.
Not long ago I completed a computer science degree, and right now I
want to get a bit more experience and confidence by trying to write
applications that are just a bit beyond what I had to write at
university. However, in the early stages of designing the application
that I have in mind, I have hit a brick wall. I can't write it the way
that I thought at first would work, because of the ColorModel classes
having no 'set' methods, so I'd like to know what _will_ work.
Please imagine the following scenario (this is not a description of
the application, but it is a simpler illustration of the same
problem). Suppose you are writing a graphical application that
simulates a digit on a traditional LCD display, as for example on
a handheld calculator. This should be achievable using a Raster that
encodes something akin to the following:
011110
200003
200003
044440
500006
500006
077770
and a changeable ColorModel, in which 0 always represents the
BACKGROUND colour and the other indexes 1 to 7 represent colours that
we will call ON and OFF. For example, if the digit to be displayed is
"4", then indexes 2, 3, 4 and 6 will be set to represent colour ON
whilst indexes 1, 5 and 7 will be set to represent colour OFF.
Similarly, if the digit to be displayed is "3", then indexes 1, 3, 4,
5 and 7 will represent ON and indexes 2 and 6 will represent OFF.
It would be nice if the ColorModel classes had 'set' methods, because
then you could make the relevant class (let's call it
DigitDisplayImage) a subclass of Image, and the rest would be elegant
and easy. But it doesn't, although I feel there _should_ be a similar
solution. Then you could write setIndex(int, Color) methods in the
DigitDisplayImage class, after which the following code example would
work to display the digit "4".
digitDisplay.setIndex(1, OFF);
digitDisplay.setIndex(2, ON);
digitDisplay.setIndex(3, ON);
digitDisplay.setIndex(4, ON);
digitDisplay.setIndex(5, OFF);
digitDisplay.setIndex(6, ON);
digitDisplay.setIndex(7, OFF);
This would be lovely.
In the absence of ColorModel classes with 'set' methods, how, in
practise, should I go about achieving a similar functionality? (In the
real application, the corresponding object needs a lot more than eight
index values and will be called upon to display far more than just
digits between 0 and 9, but I think it is better to discuss the
problem with reference to this simplified example.)
Thanks,
Adrian.

- modificare un modello della libreria jgraphAvete mai usato la libreria jgraph per i vostri progetti?
Devo graficare lo schema di un datawarehouse che ho in XML, e modificarlo
attraverso l'interazione dell'utente (per la modifica e la visualizzazione
sto cercando di usare jgraph).
Una volta modificato il grafico, devo salvare i dati nel file XML.
Il mio problema ?che riesco a visualizzare i dati XML nel grafico Jgraph, e
modificare quest'ultimo, ma a causa delle classi utilizzate
(DefaultGraphCell) non riesco a salvare queste trasformazioni in termini di
nodi del file XML.
Dalla documentazione in rete ho capito che devo estendere e modificare la
classe GraphModel e la classe DEfaultGraphCell, ma senza un esempio o
documentazione precisa non riesco a capire quali metodi devo sovrascrivere
e cosa devo modificare per ottenere il risultato voluto.
Per questo motivo sono bloccato da giorni nella mia tesi, e ci sto perdendo
un
po' la testa, vi prego di darmi una mano (anche dirmi dove devo leggere).
Grazie in anticipo!

[ERROR]
/~ppowell/includes/chat_submit_message.jsp:63: variable retriever might
not have been initialized
if (retriever.getHTML() != null && quit.length() > 0)
[/ERROR]
I can't figure out why since I'm capturing all errors because
"retriever" might not be initialized, which is the case if
hasSubmittedMessage = false. You see, if the user hasn't yet submitted
a message, nothing can be sent to the servlet, thus, the HTMLRetriever
variable "retriever" will not be initialized into a class object
because it can't unless it receives a value, which it can only do so
upon the right conditions, otherwise, no value can be passed into
"retriever".
Anyone know what I can do about this? I'm sorry but once again in PHP
this is not a problem, and I'm sorry but I have no choice but to
"translate" PHP scripts into JSP due to client dropping PHP support.
Thanx

I was looking to achieve what is shown in the 1st image.
I can get the numeric, P3, P3mod33, C7, C7mod33 to print out but not
the symbolic information for some reason?
I want to be able to allow the user to enter in a string then the
plaintext and ciphertext can be displayed.
Like this:
String input: SUZANNE
Output:
Plaintext: S U Z A N N E
Ciphertext: 28 21 20 1 5 5 26
Thanks.

- JTable model's issueHi:
I have got a JTable and its cells are JPanel's (to make Java2D inside)
displaying numbers.
The problem is that I want the cells to be editable, so when you click on
the cell, you could write some number, and the new one be redisplayed.
I wrote a method called setValue() on the AbstractTableModel class which
updates the selected JPanel numerical value, but there is a little problem:
when you click a cell, you get a line full of info about the JPanel, so if
you want to enter a number, you have to clear the cell to avoid getting an
error.
so the question is, is there a way to avoid the info to get displayed? note
that my AbstractTableModel getValue() method needs to return a JPanel..
Thanks !!

Perhaps you'd like to post valid arguments instead of vacuous taunts
to the writer of the article.
Since the iPhone has absolutely no application capability, no IM, no
email integration capabilities, and not even the ability to edit
documents or spreadsheets or powerpoint presentations, it
automatically won't affect the business smartphone market (thus, the
fact that Rim Blackberry shares went up by $34 today).
Since it does not play any of the thousands of consumer Java games and
apps (IM, messaging, picture sharing, social networking, etc) already
in the market today, it is also a crippled CONSUMER phones.
In other words, it's a pretty GUI with nothing underneath.

Sure, I'm aware of Weka and their book, but have never installed it as I find
Java so tedious to work with.
I also have limited time and bandwidth for figuring out suggested packages.
If you could help with Weka, for example by installing Knoppix 4.0.2
(possibly the cdrom version) to disk and then documenting what you to do to
install Weka, and make it work well, I'd be helped quite a bit. Ideally, of
course, would be a Debian package encapsulating all this. It may be
worthwhile mentioning this to the good folks over at debian-java -- cc'ed. [
