- Tomcat4: Default Page Encoding UTF8Hi,
I am using Tomcat 4.1.27 running servlets which worked
perfectly under Tomcat 3. The problem is: (unfortunately)
the special characters (like german umlaute) are not
html encoded. Under tomcat 3 this was no problem, but with
the new tomcat the page-encoding is wrong. When I manually
change the page encoding in the browser to utf-8 everything
is OK. I could now go through all servlets and change the
content-type to charset utf-8, but I try to avoid this.
(as there where not written by me).
Is there any possiblilty the change the default page encoding
to utf-8? (like in the server.xml or so)
Thank you for any help!!!

- reading values from JTableI am looking for a working example of a JTable that is constructed
with initial values in the cells, allows the user to change those values,
and reads the values out.
I've got three books on Swing, none of them show a write/read table.
I have no problem creating tables with nothing in some cells, and
reading the values out that the user entered.
Here is how I construct the tables:
DefaultTableModel model01= new DefaultTableModel(rowData,colNames);
JTable table01= new JTable(model01);
Any help greatly appreciated.

- create a bean on webapp startupHi,
Unsuccessfully web browsing makes me come here.
I wonder if it's possible to create a bean (used by <jsp:use-bean>) on
startup, also through web.xml. I've seen it is possible to launch a
servlet with <load-on-startup> xml element, but, as I believe I've
understood, it is NOT a persistent object.
So, i'm asking if :
- is this possible to create a persistent object through a servlet
lauched at startup ?
- is there a different way ?

- CLASSPATH?WinXP Pro, JRE 1.4.2_03
I've just discovered that according to my Environment Variables section of
the System icon (Control Panel), I don't have a CLASSPATH variable. I used
SET from a command prompt to confirm that this is the case. No such
variable. So how come I can run basic (UI) Java programs OK? Shouldn't
CLASSPATH be pointing to the jar file containing these basic classes I'm
using? The problem is, JMF installation instructions seem to say I should
add the path to the jar file to CLASSPATH, but how can I if I have no such
variable? {:v)
Am I missing something?

- JTable emulate a HTML Table?Hi,
I want to display a table of user inputted information as a table but I am
having problems formatting the layout as I want it. I have a fixed cell
width and want the cell height to adjust to fit the text entered by the
user.
I can set the widths but can only set a fixed height for a cell and am
unable to get text to wrap within it,
for example. Also with the fixed height, the single line cells would float
to the vertical center of the cell, not stay at the top. Can alignments be
set?
[date textfield][item textfield][description textarea][idenifier
textfield][cost textfield]
[submit button]
Date Item Description
Identifier Cost
12/12/03 Big Pan This is a description field that BPI420
$60
15:30 spans multiple lines an needs
to wrap. The cell height
should dynamically alter to
accomodate the text.
1/1/04 Aspirin This is a much shorter
AS123 $20
description
Am I able to do this and if so how?
Is there a better way to do this than with using a JTable? I tried doing it
with a gridbag layout but the consecutive items wouldn't stay aligned.
Please help!
Cheers

- tomcat's classpathsHi all.
I have downloaded Tomcat 4.1.27 and I would like to create some JSPs. I took
an earlier JSP app and put it on Tomcat, and I got a class not found
exception. How do I set the classpaths for Tomcat?
One more question, how do I change the web document root? For example, I
want to change it to c:\testing.
Thanks in advance.

- JTextArea SizeHello, I'm writing a java app for a pda and as the screen size is tiny I
want to write a MiniDialog class. I only want a JTextArea and an OK button
on it and I want the JTextArea to fit the size of the modal dialog.
If I pass in a long line of text then the JTextArea appears to get wider and
I have to scroll across the screen to see the text. I want it to wrap onto
the second line etc.
I must be doing something stupid!
Thanks, Kevin.

We're not talking about 1441. France didn't vote against 1441. We're
talking about the invasion "warrant" US wanted to squeeze out of UNSC.
France felt somewhat reluctant to sign that warrant because the
evidence US intelligence (sic!) produced was not so very convincing. At
the time. Later it turned out it was total bullshit. Dubya's setting up
an investigation right now. In 50 years we might get to know the...
conclusions.
> The question remains: Iraq failed to comply with the terms of UN 1441.
> What should have been the consequences of that?
Again? Well, let's hope this time you get it: the terms should have been
enforced. But not under US flag. Maybe (more than likely) under US boot.
But the flag should have been the blue UN.

Is it good way to programmatically call actionPerformed?
NewAction action = new NewAction();
action.actionPerformed(null); //maybe instead null should be something
else, but what?

java-programmer, java/berkeley-db self-test hang
Hello!
The newly updated port of java/berkeley-db hangs during self-tests on one of
my machines:
dual FreeBSD/i386 6.1-stable - no hang
single FreeBSD/amd64 6.1-stable - no hang
dual FreeBSD/amd64 6.2-prerelease - hangs
There is little CPU use and all the process is doing, according to ktrace is
the repeated:
[...]
13089 java CALL clock_gettime(0,0x7ffffeff3d00)
13089 java RET clock_gettime 0
13089 java CALL kse_release(0x654f20)

Rebuilding Java did not help... Would any Java and/or thread expert, please,
try to build the port with self-testing enabled and analyze any hang? Thanks
a lot!

- GUI locking up, but code running fine.I'm using Netbeans 5.0 beta for an IDE, with swing components. The
situation is something like this:
The program is a board game - the user chooses a building from a panel,
and then is supposed to get a message to choose what resource to pay
for it with. Here's a trace of the code:
Game (main object):
....
board[i].activate():
Game.game.setPlayer(worker);
Game.game.playerMessage("Choose a wooden building
from the building panel.");
Game.game.waitForBuild(type) :
built = false;
state = type + Game.BuildWood -
1;
mainPanel.buildings.getBP().setSelectedIndex(type-1);
while(!built)
{ Thread.yield(); }
No problems yet. This works fine, unless a building that needs to call
chooseResource is selected.
So, the user clicks one of these buildings, which activates the
following code, which is where the freeze occurs:
String r = Game.game.chooseResource():
state = Game.chooseResource;
resource = "";
while(resource.length()==0)
Thread.yield();
return resource;
Now chooseResource does work in any other context - resource gets set
by a mouseClicked event handler in a panel out there. But at this
point, the GUI stops responding. The playerMessage never gets printed,
and the click event never gets triggered. I did some investigating,
printing out numbers inside the two inmost loops, and the
chooseResource loop is continually running. I know the code's ugly,
but even so, the cause of this behavior is beyond me. Any suggestions
would be greatly appreciated!

- Eclipse bug?Eclipse bug? Using most recent version (as of a couple weeks ago,
anyway), if it sits idle for a day or two in the taskbar, it stops
responding -- or at least it is really sluggish if you try to use it
again, and not just for a short time, but until you quit and restart it.

- Dynamic resizing of JPanelDear experts,
I have the a JDesktopPane and a JPanel added to the CENTER and SOUTH
position of a JFrame respectively.
I would like to dynamically resize the JPanel upon mouseExited like the
Windows TaskBar.
On mouseExited of the JPanel i set the bounds of the JPanel to a new
size. However, the sizes do not reflect visually. I have called
invalidate(), validate(), repaint() and none seems to work.
Other than using JSplitPane to create a resizable JPanel, how can I make
this work?
Others have suggested using LayoutManagers but which one and how?
Thank you in advance.

- HashMap with primitive int keyDear All,
I have a class like this:
class CustomerOrder {
int globalID;
...
}
I have an array of these.
I'd like to store an index of globalIDs, so I can do:
CustomerOrder o = index.get(123)
I could modify my class to be:
class CustomerOrder {
Integer globalID;
...
}
Perhaps it is my C++ background, but the idea of allocating an object for every
ID when I can just use an int bothers me.
I figure a HashMap is the right tool of choice, e.g.:
HashMap<Integer, CustomerOrder> index = new ...
Has anyone out there already written a modified hashmap class that uses int as
the key?
Thanks for any tips :)

- String comparision efficencyHI!
I have an appliation that will need to parse a text of unkown length.
I get the data as an array of strings (and thus I know then how much
data it is)
I want to do several things on each "row" (that is each element in the
array) I want to
1. look for a specific word (start) and count how many of them there
are in total.
2. Highlight the word alarm and append a short description to the end
of the line
my first thought was to use
for(int i=0;i<data.length++){
if(data[i].endsWith("start"){
// do the work..
}else if(data[i].startsWith("Alarm")){
//do different work
}
}
this seems to be rather inefficent as I get two (and possibly more, my
employer did not seem think these few features were enough..)
Is there a better way to do this.
As the alarm line also contains an alarm code, I do not know what it
looks like. Any suggestions?
regards
