- getting clipboard content as rawdataI am within a java application (swing), and
I would like to get the content of user clipboard as rawdata (binary
byte array) without trying to figure out what flavor it is. I just
need to get the bytes and post them to a server.
(It can part of word doc or xls - server will try to convert that into
an image)
Does that question makes any sens (since I haven't seen a way to do
that within java.awt.datatransfer api) ?
thanks

- JTable select problemHello,
I have a great problem with my JTable. I have a JTable with few lines
and two columns. The user can select one line and with the following
statements
int column = tblSearchResults.getSelectedColumn();
int row = tblSearchResults.getSelectedRow();
Object value = tblSearchResults.getValueAt(row,column);
I retrieve the value with which I display details of a second line in a
new window (when the user presses a certain button). The problem is
when I close this new window and want to select a new line the
getSelectedColumn and the getSelectedRow returns always -1 which
says that no line is marked although I have marked a line.
Does anybody know what the problem can be? - it must concern the open
and close of the detail window, because when I omit the code line which
opens the detail window and only make System.out.println's with the
getSelectedColumn and getSelectedRow it will always output the right
line...
thx

- Univernsal IDIt seems to me any sort of ID that can be forged for under $500 is
worse than useless. Any serious bad guy can easily afford fake id.
For everyone else it is just a hassle if they forget their id.
In our past anonymity was not a right. Everyone knew everyone in the
village/tribe. You could not easily do wrong without others knowing
it was you.
If we got serious about a Universal ID, what are its characteristics?
1. costs over $1,000,000 to forge.
2. not useful to anyone other than the true owner.
3. can be scanned in under a second.
4. cannot be scanned without permission from the owner.
5. Should not need to be replaced unless lost. Additional photos
could be digitally added as you age.
6. it should be useful as a credit/debit card, id card, door key,
proof of age, link to medical records. It might even capture most of
the information needed to compute your taxes in a way that the
government has to believe you.
7. It would have to be based on encryption technology and digitally
signing information such as DNA, retinal patterns, fingerprints,
photo.
It might be reasonable to design such a card presuming the card will
have the CPU and memory of a laptop running Java.

- Focus problem on JListHello,
I made a JDialog with two JButton and one JList. I'd like to get the focus
on my Jlist, but it's always the first button (in declaration order) which
has the focus. An actionListener is added to the JButton and I put the focus
on the Jlist by "JList.requestFocus()".
Any idea ?

- DDOS Attacks Coming From www.schestowitz.comEver since I visited www.schestowitz.com I have been getting nmaped,
probed, pinged and now DDOS's with floods of requests from an ip
address that resolves to a block assigned to www.schestowitz.com.
I have reported this to my ISP who is now blocking the range from my
trunk.
They in turn have filed a complaint with Catalyst (?) who hosts the
site.
Is anyone else experiencing this kind of a problem or am I the chosen
one?

- Can I create a Thread directlyHI,
Can I create a thread directly and then start it and run it as the code below?
Thread tt = new Thread(); (or Thread tt = new Thread("thread");)

- Trouble with KeyListeners in 1.4.2I'm having trouble using KeyListeners in 1.4.2. I'm writing a graphics
application, and I'd like to change the behavior of some of the tools when
modifier keys are held down. The problem is that I use a JToolBar, which
seems to have grabbed hold of the focus and won't let go. The KeyListener
I've registered with the main JFrame doesn't pick up any events (unless I
comment out the JToolBar).
I found a fix on the boards at java.sun.com which involves registering a
KeyEventDispatcher with the current KeyboardFocusManager, and that does
allow my KeyListener to work, but any *other* KeyEvents fail to propagate
further--i.e., alt-F4 no longer quits the app, the alt-keys for my menu
mnemonics stop working, etc.
What do I have to do to get both shift-key detection and other key commands
working at the same time? I understand there were some changes to the focus
system in 1.4.x that cause these problems, but there doesn't seem to be any
documentation on how to work around them.
Any help is much appreciated.
BTW, here's the code for the KeyEventDispatcher, in case it helps:
DefaultKeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDisp
atcher(
new KeyEventDispatcher() {
public boolean dispatchKeyEvent(final KeyEvent e) {
processKeyEvent(e);
return true;
} // dispatchKeyEvent
} // KeyEventDispatcher constructor
);

- references and a binary treeHello,
I am new to Java. I am filling a binary tree with values using a loop,
so when I need to descend one node deeper at the end of the loop, I
use node=node.right for example. Consider this pseudo code:
//...
while(1) {
node=new Node(new Leaf(),null);
node=node.right;
}
I thought that the node variable will contain reference after this
operation. But it does not, because when I look at the root of the
binary tree, it does not get filled any further after the
node=node.right operation.
So my question is, what actually happens in the node=node.right , I
tought that it should be only copying the references, not the values.
I coded the same in c++ and instead of references I used the pointers
and it worked right as I expected.

- Measuring string bounds in headless serverI have a problem with calculating screen string width for the browser
client.
I'm outputting a stream of content type application/vnd.ms-excel and
sending back an XML spreadsheet. (No complaints about using Mc$oft
products, it's what's needed!)
Excel does not autosize columns which contain string data, so the text
columns are the standard Excel width, and the text is wrapped onto about
7 lines. See
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnexcl2k2/html/odc_xmlss.asp
for details of the XML format.
Excel does allow you to specify the with of a column in points, so I was
using the awt Font classes to calculate the string bounds in pixels. I
explicitly set the resolution to be used to 72dpi by creating a
FontRenderContext with an AffineTransform with a scaling factor of (1.0,
1.0), so that asking the pixel width, gets the point width.
This worked fine testing it on my windoze machine, but on the Unix
server, it's obviously running in headless mode, and anyway, it doesn't
have the Arial font which I'm specifying in my spreadsheet as the font
to use.
Is there any way of calculating the width of a string in points knowing
its font and the point size of the font? You shouldn't need a graphcs
environment, just the font information. I have all the .TTF files, I
could copy them to the Unix machine if Java could use them and do the
calculation.
I hate leaving the user interface looking so shoddy with wrong sized
columns!
It SHOULD have worked in a headless environment according to
http://java.sun.com/j2se/1.4.2/docs/guide/awt/AWTChanges.html#headless
and we are on version 1.4.2_01. It actually blew up in awt code:
java.lang.NoClassDefFoundError
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:141)
at
java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(GraphicsEnvironment.java:62)
at java.awt.Font.initializeFont(Font.java:308)
at java.awt.Font.<init>(Font.java:344)
That's when I'm trying to instantiate a
new Font("Arial", Font.PLAIN, 10);
Any ideas anyone?

- My app runs too slow (lots of code follows)Let me start out by saying that I'm admittedly not a great programmer.
I'm sure that my problems are my own fault and not really Java's. I
have a program that I had originally written in Perl. For various
reasons I decided to rewrite it in Java, but now that I'm nearly done,
I'm not sure if I want to use it because it's very slow and resource
intensive compared to my Perl version.
Quick summary of what the program does: it performs MD5 sums on a
number of files, stores the sums and compares against them on future
runs -- sort of a cheesy tripwire, checks that some processes are
running, checks the contents of a few small files like /etc/passwd,
/etc/shadow, etc. It's strictly a Unix program for me.
My old perl version generally runs the comparisons, checks file
permissions, reads a couple of files, along with reading the last few
minutes of a few logfiles (something I have yet to really implement in
my new Java version, which will make it run even longer, of course) in
less than a second. My java version does it (minus the logfile
reading) in anywhere between 10 and 15 seconds.

I found it at last. A library was missing (package 'glibc-locale').
Everything is OK now.

java-programmer, What are Good Java books?
Hi there,
I'd like to buy one or two Java 2 SE books as
text and reference. I need books with good
examples, exercises, projects and solution.
Yes, I know that there are a lot of good
books in the market, but I don't have time to
compare them.
I already have experience in C and C++
programming and a little bit of Java.
Please reply to the group. Thanks a lot.

They have a book section geared by level and subject. : )
It is also a great resource for Java folks.

Take a look at the Java section of TechBookReport for detailed reviews of
Java titles (http://www.techbookreport.com/JavaIndex.html). If you have some
OO experience then Bruce Eckel's Thinking In Java is worth considering.

I highly recommend Java 2: The Complete Reference, Fifth Edition.
http://tinyurl.com/29z92
The title is somewhat of a misnomer, because it sounds like it would
be a class library reference, but it isn't. It teaches the Java
language very clearly and completely, and shows how to use many of the
most commonly useful standard Java libraries.
However, this book doesn't meet your criteria of containing exercises
and solutions; it is not a school textbook. So if that's important to
you, you may want to look elsewhere. However, it does have some
complete sample programs at the end that you may find usefully
illustrative.

java-programmer >> What are Good Java books?
I'm a big fan of "just JAVA2 by Peter Van der Linden, published by Sun
Microsystems.
He not only gives a good overview of the language, but also covers a bit of
the general platform and important IDEs and concepts. I think it's the
fastest/bestest way to become conversant in Java.

"Thinking in Java" by Bruce Eckel. It's mostly a free download, though
it's probably easier to just buy it.

- Tomcat 5.5.7 and Axis 1.0 problemI'm using Tomcat 5.5.7 and deployed Axis 1.0 samples on it. (using JDK
1.5.0_01)
happyaxis.jsp is happy! and finds all required libraries (but not
optionals!)
the list of services is shown correctly (has 2 servies, AdminService
and getVersion)
but when I click on call a local end point the result is:
<?xml version="1.0" encoding="UTF-8" ?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server.userException</faultcode>
<faultstring>java.lang.NullPointerException</faultstring>
<detail />
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
I'm not sure, but I think the problem may be because of the new Compile
mechanism Tomcat 5.5.x uses (depending on JRE not JDK).
How can I recover from this problem?

- Thread Contructor QuestionHi All,
I'm curious about something. In a Java certification study guide,
they have the following code and they ask what the result is:
class MyThread extends Thread
{
public static void main(String [] args)
{
MyThread t = new MyThread();
Thread x = new Thread(t);
x.start();
}
public void run()
{
for (int i = 0; i < 3; ++i)
{
System.out.print(i + "..");
}
}
}
It's simple enough. Except, earlier in the text (and in the Java API)
they mention that the only constructors for the Thread class are:
Thread()
Thread(Runnable target)
Thread(Runnable target, String name)
Thread(String name)
Thread(ThreadGroup group, Runnable target)
Thread(ThreadGroup group, Runnable target, String name)
Thread(ThreadGroup group, Runnable target, String name, long
stackSize)
Thread(ThreadGroup group, String name)
I don't see Thread(Thread). And I don't see how it can be a Runnable
except for that they share the same method: run().

- Remove "Padding" from GridLayout/ButtonsI have a 10x10 grid of buttons created using a GridLayout. Each button has a
30x30 pixel GIF icon on it.
Unfortunately, nomatter what I try, I can't seem to get each icon to sit
side by side (so that there's no gap between them). Currently there's an
approximately 5 pixel gap between each GIF image.
So far I've tried:
grid_button.setSize(new Dimension(30, 30)); // to set each button to 30x30
_board_panel.setSize(new Dimension(30*y_size, 300*x_size)); // sets grid
board to 30 times the number of grids in each dimension
... but neither seems to work.
How do I get it so that there's no gap between each GIF? I need the size of
each square in the grid to be fixed to exactly 30x30, not relative to the
size of it's holding panel.
TIA.

- Web page to build a web pageDoes anyone have any suggestions or examples of creating a web page to
allow an end user to design a form. I need to design an application
where the end user (administrator) can design a form with standard
html components such as text boxes, drop down lists etc. Attach drop
down list to database tables, and enter expression for certain fields.
Then once the form is saved another user (business) can display the
form and fill it in, at which time the expressions would be evaluated
based on the data entered.

- How can I know which button is clicked in JDialog ShowModalHi, all,
In a programme using swing (homework), I use a JDialog window. There are

d.setModal(true);
d.show();
if (d.close = btnOk){
...
} else if (d.close == btnCancel){

}
In fact I want to use this way like in the windows programming:
int i = d.showModal();
if (i == ok){
...
} else if ( i == cancel){
...
}
Please help me. I am a newbie in swing programming.
Thanks a lot.

- java sockets passing objectsI have a very simple java application in which I need to pass an
object via sockets. It is an object that I have defined, which has
implemented Serializable. The problem occurs when I send an instance
of the object, when I recieve it on the other end, it is null. The
reciever does in fact recieve an object of the correct type (my user
defined object) but it is empty although the one I sent was not. Is
there something I need to do in the readObject() or writeObject()
methods? Any help would be appreciated, thank you!
For reference, here is my user defined object:
class nodeMessage implements Serializable
{
String text;
int messageID;
int senderID;
int recieverID;
String[] stamp;
public nodeMessage(){}
public nodeMessage(String t, int mID, int sID, int rID,
String[] s)
{
text = t;
messageID = mID;
senderID = sID;
recieverID = rID;
stamp = s;
}
public String getText()
{
return text;
}
public int getMID()
{
return messageID;
}
public int getSID()
{
return senderID;
}
public int getRID()
{
return recieverID;
}
public String[] getStamp()
{
return stamp;
}
public void addStamp(String s)
{
stamp[stamp.length] = s;
}
private void writeObject(java.io.ObjectOutputStream out)
throws IOException{
}
private void readObject(java.io.ObjectInputStream in)
throws IOException, ClassNotFoundException{
}
}
