- [encoding]Stupid question regarding encodingI have written a java plugin for an application that reads a file to execute
a series of actions ; when I parse my text file I check for the existence
of the following line "#HEADER" ; it works fine on my equipment ; on
Windows somebody working with the text file encoded in utf-8 told me that
there is problem as the line containing "#HEADER" is not found !
Now I am a little bit puzzled about all this :
(a) when you write java code and compile it what happens to the
string "#HEADER" because it will be used in the following test :
if (line.equals("#HEADER") {...}
where line is read from the text file with encoding as is on the machine
where the class is executed ? in other words you are comparing what to
what ?
(b) when with a Java app you read a text file can you get its encoding
format like utf-8 or ANSI or whatever to decide about some actions to be
taken ?
I think the problem could be easily solved by replacing "#HEADER"
by "_HEADER" but I have to go to the bottom of this to understand what is
going on.

- Serial Port CommunicationsI have a java application that I wrote that collects data from a
serial port on a laptop from a data collection device. Program works
well.
My bosses would like certain conditions to draw more attention than
just using the laptop's monitor. They would like two lights and a horn
to be controlled as well.
Tackling the serial input device was pretty easy, but I am not sure
where to start with this request.
1) I only have one serial port on the Laptop, but they want to control
4 devices (horn, light 1, light 2, data collection device). So how
do I handle that?
2) Where would I go to buy the other devices and what device would I
have my java program talk to in order to control them?
Thanks,

- [OT] Project documentationWell, they _are_ all Java projects... but it's OT, I know. I need to get a
handle on project documentation. Can someone toss out some options for
generating documentation? What is (or could be) behind the numbered
chapter/section/subsection format of the various PDF files (specifications
and manuals) that I download?
I have so far adopted the xml and xsl transform found in many Apache and
Jakarta projects, and that has helped tremendously for HTML documentation,
but I need to be able to hand over a document and say 'this is what I'm
building'.
Thanks,

- DOM tree questionHi all,
For code sample domEcho02.java, every element node will have an empty text
node like below. looks like there is no direct method in the treemodel impl
or in the adaptor class that I can control this. how can I get rid of it?
// sample xml node
<pnode attr1='0'>
<cnode1 att1='attr'><value>blah</value></cnode1>
</pnode>
// will be translated in tree nodes
element: pnode
text: (empty, unnecessary)

- Advanced Tooltips in JavaHi
I want to implement dynamic interactive tooltips in java so that the
user can expand / collapse them. Also, if there are hyperlinks in the
tooltip text, the user should be able to follow up this link. For the
same purpose, I need to be able to catch any events associated with
tooltips.
I tried to search a lot on how to customize the behavior of tooltips in
Java, however couldn't find any useful information. Does anyone know
about how to proceed about this? Any suggestions / pointers would be
greatly appreciated.
Thanks,

- JButton layout - equal width with no absurd stretchThank you for taking the time to enlighten me. I have been searching
and trying different things but nothing seems to work for me. All I
want to do is have a column of JButtons to the left of a JScrollPane.
I want the buttons to have equal widths (the widest button at its
minimum text-fitting width, all others stretched to an equal width) and
be only as high as they need to be for their text. The scroll pane can
fill the rest of the width (and height for that matter). Something
like this:
+----------------------------------+
| |
| +--------+ +-------------------+ |
| | A | | | |
| +--------+ | | |
| | ABCDEF | | | |
| +--------+ | JScrollPane | |
| | ABCD | | | |
| +--------+ | | |
| | | |
| +-------------------+ |
| |
+----------------------------------+
I tried box layout, but then the buttons are not equal widths. Border
layout makes the buttons equal widths, but stretches them to be as high
as the scroll pane. Grid layout stretches them both vertically and
horizontally. I think I tried gridbag layout and had the same problem
as grid layout. The type of layout I want for the buttons reminds me of
how a table would layout in an HTML document. I want to avoid using
literal size values because of L&F issues on other platforms. Shrinking
the height of the scroll pane is not an option. Does anyone have any
suggestions?

- JSpinner causes trouble to JB 2005 designer...X-No-Archive: yes
Hi.
I try to build a GUI with the JB 2005 designer (JB 2005
Enterprise-Trial/Fondation version).
Basically it works until I want to add a JSpinner component. Then this
error happens: "null processing BeanInfo class
javax.swing.JSpinnerBeanInfo"
The component is not added. So I add it manually. But the rest of the
GUI components (following the JSpinner member variable) is mixed up
then.
Is there a workaround to this? Thanks.

- Socket error Windows getInputStreamHello,
Java version is 1.5.0_09. I am trying to connect from a Windows
machine to another Windows machine using sockets . Getting a socket
error for the following line. and throws EOFException
Socket s = null;
ObjectInputStream sin = null;
ObjectOutputStream sout = null;
s = new Socket( host, port );
sout = new ObjectOutputStream( s.getOutputStream() );
//write data to socket
sout.writeObject( req );
sout.flush();
InputStream is = s.getInputStream() );
sin = new ObjectInputStream( is ); // This line gives error
If I step into ObjectInputStream, I see:
public ObjectInputStream(InputStream in) throws IOException {
verifySubclass();
bin = new BlockDataInputStream(in);
handles = new HandleTable(10);
vlist = new ValidationList();
enableOverride = false;
readStreamHeader(); // This line gives error
bin.setBlockDataMode(true);
}
However, the same code works when I try to connect from Linux(Red Hat
Enterprise Linux WS release 4 (Nahant Update 5)) to Windows. Turned
off Windows firewall but no luck.
On the Windows Server I am trying to connect to a server agent waiting
on port 2002 that helps me connect to Citrix running on that machine.
The agent runs as a Windows service.
What could be wrong here?

- Is Java really faster than Obj-C ? Should Apple dump Obj-C and go with Java?The old notion that Java on desktops is slow might have to go out the
window if more studies show this:
http://homepage.mac.com/spullara/rants/C1464297901/E775622191/index.html
Again, this points out the fact that there will probably be a
renaissance of Java on desktops as it percolates on Linux and Macs and
Windows desktops. We use Mac OS X iMacs at work and Java apps as
MoneyDance (a personal finance software that runs on all 3 desktops,
although it looks sorta crappy in windows) are very good looking and
extremely fast.
Now, if only IBM's open source eclipse made better looking SWT apps on
Mac and Linux...

- Weird Problem w/ DecimalFormatThe following code snippet:
static DecimalFormat nf=new DecimalFormat("#####.00");
System.out.println(nf.format(1000.10));
sometimes stops working properly and instead of seeing 1000.10 I see 1000,10
(note the comma). I can't for the life of me figure out what is going on...
I'm using Java 1.3.1 on a Sun workstation.
Any ideas?

- Accessing the name of the CLASS/JAR file invokedHello,
I am trying to pack all my files into a JAR - this includes CLASS
files and other textual files such as help, std configs, etc.
I would like to be able to extract them from the Java app straight out
of the JAR - and for this I need to know what the name of the JAR file
invoked was (it might have been renamed for X reasons)
Is there any sure way to do this? (the alternative is to have an
external file to contain said data, but I want to know if a way to
have everything self-contained exists, first)
Thanks,
Andrew

java-programmer, has anyone gotten this exception using SkinLF?
I get the following exception when loading certain skins with SkinLF
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

at
com.l2fprod.gui.plaf.skin.SkinSeparatorUI.getPreferredSize(SkinSeparatorUI.java:84)
It only happens when i try and load certain dialogs, and I'm not sure
which dialogs it happens it. I can try and come up with a small example
if no one has seen this before. (An example of a skin this occurs with
is: b0sumiErgothemepack.zip)
thanks!

I just checked it and it works on my Windows 2000 machine.
I am currently playing around with themepacks for SkinLF and noticed,
that a lot of them are a little bit "unclean". The rc files reference
image files which are not there and I got a lot of exceptions when
loading different themes because of that. Most themes work despite those
exceptions.
In the sources I can look at right now the line of your exception is
responsible for determining the height of the "hline-file". If you now
look in the gtk/gtkrc file from that themepack you can find a section
for HLINE and that refers to a file hline.png and that in turn is not
present in the themepack.
Fixing the themepack seems to be the best solution to me. (Providing
some default behaviour for SkinLF would be another solution, but well,
the themepack should be ok in the first place...)
Best wishes,
Rainer

Hi Rainer,
I was wondering if it would be possible for you to send me the
"cleaned" up themepacks that you have touched. I figure there isn't
much point in fixing the same themepacks you have done.
thanks!

Hi,
sorry for the late reply - was a little distracted.
I was digging into the "deeps" while creating my own themepack, so
basically I only produced a clean own themepack. I did not need to fix
the others.
Best wishes,
Rainer

- Newbie Question: LayoutsI've been having the toughest time with this....
I want to have a JFrame with 3 containers in it.
The containers are laid out top to bottom.
Inside the first 2 containers I want 4 rows of a JLabel and
JTextField. Components are lined up in both containers so that the
labels end and textfields start at the same place on each line. These
two containers also have a titled borders, as does the third container
which is just a JTextArea. My questions are: what type should these
containers be? what type of layout should I use for them (and what
should the parameters to the method be if any)?
Thanks.

I don't think you're supposed to construct your own form-- there's more to
it than the data. If you look at the API, you'll see some other attributes
that your own form is probably missing.
http://struts.apache.org/api/org/apache/struts/action/ActionForm.html
There is a way to ask the framework to make you a new form bean, but in this
case you don't really need that.
Instead of trying to replace the form bean with your own, try copying all of
the matching properties into it with:
BeanUtils.copyProperties( form, objectFromDatabase );
The Struts example webapp has an example of prepopulating a form. Using
forms as Data Transport Objects is generally frowned upon as it
unnecessarily couples your data access layer to Struts.

- System clock monitoringwe have a java applet game that relies on a thread that ticks at 10n
miliseconds. Our problem is that we use the system clock time to see
the interval of ticks, and if a user manipulates the clock setting,
then we get erronous tick times.
Is there a way we can avoid this, or use the hardware clock , or some
solution where the user inteferenece will not disrupt the game ?
Thanks for all your suggestions,

- Graphics2D to ImageIcon problemI'm trying to do something that should be very simple.
I want to create an applet (or application, doesn't matter) to display a set
of drawn objects (drawn with a Graphics2D object). I want to be able to display
these objects in a pane by choosing them from a combo box. Two panes, one
on top with the combo box, one on the botton with the graphic.
I managed to get the images to be drawn in a simple panel stacked next to
each other but I really want to be able to select them and have them drawn
one at a time when selected in the combo box.
My program currently just instantiatest my classes that do the Graphics2D
drawing (the classes extend JPanel and just have a paint method in them)
and puts them in a grid layout.
REAL QUESTION: I would like to create an ImageIcon and just update it
with a new image when the combo box selection changes.
The problem is I can't seem to find a way to convert a
BufferedImage or a Graphics2D object into an ImageIcon.
Should I be doing this in a different way?
I don't work with JAVA everyday (though I love the language) and GUI and
graphics things just frustrate me to no end. I still haven't got the right
model in my head.
Any help would be very apprciated. Thanks,
James Kimble

- Date ArithmeticArg,
So I know I use the Calendar abstract class. And I am betting that I use
the Add method.
Could I see a example of some date arithmetic, e.g. number of days from
today since 01/01/1964.
Must I work out the differences by year, month, day individually, convert to
a common unit of time, add them, then convert to a displayable unit of time?

- String ExternalizationI know, generally, hard coding strings is not the best thing in the
world to do. However, if I am not planning on changing those strings
(especially if the application has already been written - and it's
big), is there any reason to incur the overhead (time to implement,
overhead of the use of Properties, etc) to convert an application so
it uses a .properties file.
Just curious what other developer opinions are.
Thanks.

? ummm...It seems that you are dangerous...jijiji
Well, well. Movements, like the rotation, are too fast.If I move a
little the mouse, the scene is moved very fast.
I Can I make it slower?
(Sorry for my writing. I'm not english, and I'm beginning with the
English...^_^ )

- BPEL Products(Business prcess execution Language 4 webservices)Hi,
I had a few questions about BPEL products
1) Can you let me know the BPEL Servers available in the market. Do
these need to be integrated with J2EE appservers or can they run as is
if all I want to do is integrate a few Java applications and
webservices to the flow.
2) How powerful are Weblogic Integration suite and Websphere MQSeries
Integrator for integrating Webservices using BPEL. Also how easy is it
to develop this kind of flow. Collaxa has a more pure BPEL product
that seems easier for the above task.
Thanks in Advance,
Regards,
Rahul

- Secure access to database applicationHi All
Just looking for a bit of advice. I have an muti-user application
that I'm developing that talks to an Oracle database. What's the best
way (or at least a good way!) of securing user + password access to
the program? I've currently got a user table in the database and I
fetch whether the login credentials match what's in that table - but I
log in as an admin user to the DB in order to fetch the user table, so
admin password is coded into the application - this is obviously
bad.
Ideas? I presume there's a standard way of doing these kinds of
things :o)

- grabbing text from non-edit java windowHow do I get the text (in a java program) from a java window that is not an
edit window (ie, cannot hilight the text with a mouse)? ie, is there
something similar to in functionality to Windows API GetWindowText()?

- imcompatible type when converting a List to arrayI have an ArrayList<Guest> which I want to convert to an Array, but I'm
getting:
init:
deps-jar:
Compiling 2 source files to /home/thufir/JavaProject28/build/classes
/home/thufir/bcit-comp2611-project2/src/a00720398/view/Tabs.java:15:
incompatible types
found : java.lang.Object[]
required: a00720398.data.Guest[]
Guest some_guests[] = FileUtil.getGuests().toArray();
1 error
BUILD FAILED (total time: 6 seconds)
If I change it to:
Object some_guests[] = FileUtil.getGuests().toArray();
then it works fine, but that's rather absurd because I know that the type
is Guest so I don't see why it would have to be an array of Object.
Surely I don't have to cast to Guest?
thanks,
Thufir
