- singlethreadmodel vs. synchronizeI have a book that is explaining servlets and implements
singlethreadmodel instead of using synchronize with wait and notify.
does that only work with servlets? which is better?

- Tweaking DefaultTreeCellRendererHello,
I'm implementing Drag & Drop for my JTree and I got everything working so far.
There is only one thing that I'd like to add: I would like to highlight the node
that is the current drop target somehow. I did manage to select the node
during my dragEnter() and dragOver() events, but I'd rather not change the
tree's selection during dragging.
So I thought I could customize the TreeCellRenderer used. What I did is the
following:
I extended DefaultTreeCellRenderer and added a method to set the current drop
target row. When creating my tree I set the new renderer as the tree renderer
(which is working because I can see the methods beeing called when adding a
System.out.println())
The I overwrote getTreeCellRendererComponent(). Before calling the
super.getTreeCellRendererComponent() I check if a drop target row is set, and if
it is I pretend the cell is focused:
public Component getTreeCellRendererComponent(JTree tree,
Object value,
boolean sel,
boolean expanded,
boolean leaf,
int row,
boolean hasFocus)
{
boolean drawFocus = hasFocus;
if (this.dropTargetRow != -1 && row == this.dropTargetRow)
{
drawFocus = true;
}
return super.getTreeCellRendererComponent(tree, value, sel, expanded, leaf,
row, drawFocus);
}
But this does not work. I have added debuggin code and the dropTargetRow
variable is set and initialized correctly.
What am I missing here? When I pass a hardcoded true or false to the super call,
it does work (all nodes either always focused or never)
Thanks for any input

- void methods and "return"hi,
void methods cannot return values, however, i noticed that i can still
use "return" without any value to exit a method like this:
public void myMethod(int arg0)
{
if (arg0 == 0) return;
...
}
question: is the above ok or will i get errors with other java versions.
i'm using jre1.4.1_02 in eclipse.

- Applet, use seperate classHi I am making a applet that uses a seperate class, but my IDE tells me
that when I try to use my seperate class, that it cannot resolve the
symbol (ie cant find it) ,or if I try to import the class, that it
expects a '.'. Here's the code
import java.awt.*;
public class Buiding
{
private int width, height, topBuffer, sideBuffer, widthOfWindow,
heightOfWindow,
heightOfThird;
public Buiding(int width, int height)
{
this.width = width; this.height = height;
topBuffer = height/20;
sideBuffer = width/20;
widthOfWindow = width/10;
heightOfWindow = height/10;
heightOfThird = height/3;
}
public void draw(int x, int y, Graphics page)
{
int origionalX = x, origionalY = y;
page.drawRect(x, y, width, height);
int randomXWidth = x - widthOfWindow;
int randomX = (int)(Math.random()*randomXWidth);
int randomYWidth = y + heightOfThird - 2*topBuffer -
heightOfWindow;
int randomY = (int)(Math.random()*randomYWidth);
randomX += x;
randomY += y;
page.fillRect(randomX,randomY,widthOfWindow,heightOfWindow);
}
}

you can find one on my side:
http://www.software47.de/eng/software/datetimepicker/datetimepicker_en.htm
it's absolutely free, you can use it as you like.
since i was looking for a free datetimepicker myself, but found nothing, I
wrote one the last days...
If you find bugs or have ideas to better it up, let me know.
Java 1.4 is needed! (because of frame.setundecorated...)

- CLASSPATH clobbering, win2kfrom <http://java.sun.com/j2se/1.4/install-windows.html#Environment>:
"Choose Start, Settings, Control Panel, and double-click System. On
Microsoft Windows NT, select the Environment tab; on Microsoft Windows
2000 select the Advanced tab and then Environment Variables. Look for
"Path" in the User Variables and System Variables. If you're not sure
where to add the path, add it to the right end of the "Path" in the
User Variables."
under System Variables the value of "Path" is:
"C:\Program Files\Java\jdk1.5.0\bin\"
from
<http://java.sun.com/docs/books/tutorial/getStarted/cupojava/win32.html#2c>
I followed these instructions:
"If you still have problems, you might have to change your CLASSPATH
variable. To see if this is necessary, try "clobbering" the classpath
with the following command:
set CLASSPATH="
"clobbering" fixed the problem, "java HelloWorldApp" worked fine.
However, since I need to clobber the CLASSPATH variable I need to
change it's value, but to what, pls?
thanks,

- Eclipse Tomcat Project StructureHi All,
I am using Eclipse 3.0 with a Tomcat plug in.
I am trying to create multiple web projects using Tomcats webapps
directory. Eclipse will let me set up one project with under the webapps
folder but when I try to add a new project I get the following error
C:/jakarta-tomcat-4.1.30/webapps and C:/jakarta-tomcat-4.1.30/webapps
overlap.
This I am sure will have a simple explanation... I am thinking that it
should be ok to work on multiple web projects with different names at the
same time under Tomcats webapps folder ?
Thanks in advance

The Eclipse IDE is very huge and bloated. You might
want to take a look at one of these alternatives:
http://jedit.org
Supports several development languages and a huge
assortment of feature plugins. You can script out
your own shell tools as macros and make them available
as buttons on your toolbar.
http://netbeans.org
Similar to JEdit but with a GUI designer for Java apps.
Also lots of plugins and multi-language support.
The nice thing about having IDEs written in Java is
the cross-platform support; using the same environment
on any Java-enabled OS.

In Six Sigma, we figure out the cost of quality, and the cost of poor
quality, and make economic decisions. This is one of the major
differences between SS and earlier quality initiatives. Although there
is plenty of statistics, Six Sigma is about "show me the money".
Based on many years of experience (I'm a really old fart), I agree that
"optimal" code is rarely optimal. You should make an appropriate
investment in the code. In today's world, that often means just barely
working. But there are situations where you want good, solid
maintainable code. It can be tough knowing the diffeence.

This is true. More generally, it becomes impossible _by any practical
means_ to ensure that there are no errors. Unfortunately the
threshold size for this limit of practicality is very small.

And I would say that "smallish" means "comp-sci 101 exercise". E.g.
Write a program to calculate the quadratic formula.

Again, this is very true, and the incidence grows with the square of
the number of features. (if not faster).

Agreed. You have to get your fingers and eyeballs on it. You have to
torture test it. You have to let a million monkeys into the room to
bang on it. You have to work hard to anticipate systematic weaknesses
and failures, and probe them all.
Each one of these things helps; and yet none are completely
sufficient. Spacecraft will still think they are on the ground when
they are 100Y up. They will still overshoot orbits because of unit
conversions. Billing systems will still send bills for negative
amounts. Telephone systems will still randomly drop you. And (though
it hasn't happened to my knowledge) airplanes will suddenly flip
upsidedown when they cross the horizon.
>This is not to say we should not test. It simply means that we

Agreed. Nothing gets rid of all the risk. All we can do is mitigate
the risk. Testing is a *big* part of that, but is not the whole
enchilada.
>It is also important to understand that more tests will not necessarily

It is remarkable just how much the test-first discipline helps in this
regard. The act of designing your system around tests that you write
first goes a very long way towards helping to organize and structure
the code in a maintainable way.
Again, this is not a panacea. One should not depend on test-first as
the sole source of good design and structure. But it *does* help a
lot!

- Mystery of the Shrinking JScrollPaneI've got a slight mystery that I can't fathom, and was wondering if someone
could help me understand what I've done wrong.
I'm trying to create a simple interface within a defined width and height.
It consists of a top half, and a bottom half.
The top half is a sideways-scrolling panel containing a bunch of smaller
panels side-by-side, in a GridLayout. This can expand to fit the width of
the overall UI, but must never take more height than it actually needs to
show the smaller panels in full.
The bottom half is simply a panel, which should absorb all extra height and
width.
If I add sufficient images to NOT exceed the width of the overall UI,
everything works as expected; the JScrollPane expands to fit the images'
height into its viewport, and the filler panel below takes up the slack.
But if I add another small panel, enough to exceed the width of the overall
UI, it goes wrong; the JScrollPane shrinks to practically nothing. I have
set the preferred height of the small panels and of the panel they sit in
(which is inside the scroll pane), so it's not as if it shouldn't be able to
figure out how tall it should be; after all, it figured it out when they
didn't exceed the width.
I just can't understand why it should suddenly shrink.
Here's an applet that will demonstrate the problem:
First, the HTML file to run it:
<HTML>
<HEAD>
<TITLE>TestShrinkingScrollPane</TITLE>
</HEAD>
<BODY>
<APPLET code="JTestShrinkingScrollPaneApplet.class" width="840"
height="640"></APPLET>
</BODY>
</HTML>
Now the single java source file to compile (compiling using 1.4.1_03),
JTestShrinkingScrollPaneApplet.java :
import javax.swing.JApplet;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
import java.awt.Insets;
/**
*
*/
/**
* @author Jason
*
*/
public class JTestShrinkingScrollPaneApplet extends JApplet
{
/**
*
*/
private static final long serialVersionUID = 1L;
public void init()
{
final int NUM_SMALL_PANELS = 5 ;
// Add a panel with GridBagLayout to the content pane as our root
component.
JPanel backPanel = new JPanel();
backPanel.setBackground(Color.RED);
backPanel.setLayout(new GridBagLayout() );
getContentPane().add(backPanel);
// Create our panel that will scroll sideways, and its contents.
JPanel scrollablePanel = new JPanel();
scrollablePanel.setBackground(Color.BLUE);
scrollablePanel.setLayout(new GridLayout(1, NUM_SMALL_PANELS, 0, 0) );
// No gaps between cells. Unlike FlowLayout(), this forces it on to one
row.
for (int panelIndex = 0 ; panelIndex < NUM_SMALL_PANELS ; panelIndex++)
{
JPanel smallPanel = new JPanel();
smallPanel.setBackground(Color.YELLOW);
smallPanel.setPreferredSize(new Dimension(160, 110) );
scrollablePanel.add(smallPanel);
}
// With no gaps between cells, the overall size needed is obvious:
scrollablePanel.setPreferredSize(new Dimension(160 * NUM_SMALL_PANELS,
110) );
// Create the bottom panel, that will absorb the extra height available.
JPanel fillerPanel = new JPanel();
fillerPanel.setBackground(Color.GREEN);
// Now create the grid bag.
GridBagConstraints constraints = new GridBagConstraints();
constraints.anchor = GridBagConstraints.CENTER ;
constraints.gridheight = 1 ;
constraints.gridwidth = 1 ;
constraints.gridx = 0 ;
constraints.insets = new Insets(0, 0, 0, 0);
constraints.ipadx = 0 ;
constraints.ipady = 0 ;
constraints.weightx = 1.0 ;
// The wide, scrollable panel - it can absorb the width, but must not
// absorb any more height THAN IT NEEDS!
constraints.fill = GridBagConstraints.HORIZONTAL ;
constraints.gridy = 0 ;
constraints.weighty = 0.0 ;
backPanel.add(new JScrollPane(scrollablePanel), constraints);
// The other panel - it can absorb the width AND the height.
constraints.fill = GridBagConstraints.BOTH ;
constraints.gridy = 1 ;
constraints.weighty = 1.0 ;
backPanel.add(fillerPanel, constraints);
}
}
If you compile and display it as it stands, you can see the JScrollPane is
quite rightly displaying the yellow small panels in full height.
If you now change NUM_SMALL_PANELS to 6, which goes beyond the width, and
then re-display it, you'll see the scroll pane collapses.
Any ideas as to why this happens? I've tried setting the viewport preferred
size but it doesn't make any difference. The best I can do is manually set
the scroll pane's size to the needed height + a scroll bar's preferred
height but that is neither elegant nor perfect - I want to know why it goes
wrong!
Any help on the why would be appreciated.

- Java RPCHi All,
We have a set of application that communicates with embeded devices
that runs linux. Now we decide to use xml-rpc to send commands to the
devices with Apache's xmlrpc (or any other). We only need to generate,
and parse the structured xml string that contains the method name and
parameters. In other words we dont want to use a rpc server.
My question is how can I obtain the xml string of RPC command by only
suplying the method name and a vector that contains the parameters.
ps. In addition to primitive data types, parameters may contain
struct, array and etc.
Thanks in advance for your answer..

- checking for org.omg.CORBA.OBJECT_NOT_EXISTHi,
I'm writing a java CORBA client, using the Visibroker ORB. Sometimes
when I call methods on the remote object references I get the following
exception
org.omg.CORBA.OBJECT_NOT_EXIST: vmcid: OMG minor code: 0 completed:
No
Is there some way that I can check beforehand whether this exception
will be thrown, i.e. whether the remote object still exists? I thought
that I could do it like this:
if (myRef._non_existent()) {
// get a new myRef
}
myRef.doRemoteMethod();
But I've found that _non_existent() throws exceptions. Is there a
better way to check for the state that causes an OBJECT_NOT_EXIST
exception?

Two points:
1) This question is off-topic for this (non-existent) group.
2) Does the version of Netscape you are using claim to be XHTML
compliant? Are you identifying your document as as XHTML document and
not simply an HTML document?

- Setting Appender's fields in Apache's Log4JHi,
In the following code snippet (which is written to create a
FileAppender & make log4J log to that file):
import org.apache.log4j.*;
class sample
{
....
HTMLLayout layout = new HTMLLayout();
layout.TITLE_OPTION = "DataSE Log";
String logFileName = "Log.txt";
Appender appender = new FileAppender(layout, logFileName, true);
appender.immediateFlush = false;
appender.bufferedIO = true;
appender.bufferSize = 64;
Logger logger = Logger.getLogger();
logger.addAppender(appender);
.....
}
the above snippet is not inside any method. Its directly within the
class. In the above snippet, I am encountering 2 types of errors:
1. Am using the fields of the classes FileAppender & layout. The usage
seems to be wrong, because am getting the error "'synatx error on
token(s); misplaced construct(s)" & similar errors.
2. how to specify the bufferSize? Just as '64' or '64K'?
Thanks.

- Torque and WebsphereWe are implenting a J2EE project where WebSphere is handling
connection pooling for the application calls to a database. We have a
JDBC Resource configured which tested successfully. We also have the
application successfully connecting to the database which is confirmed
by the following error message.
rethrown as org.apache.torque.TorqueException: [IBM][CLI Driver][DB2]
SQL0204N "TSTUSER.PERMISSION" is an undefined name.
The problem is apparent, TSTUSER does not own a table called
PERMISSION and in fact this table is owned by the user TELUSER and our
intention is for TSTUSER to execute DML against it. We have not been
able to configure the schema.xml file nor the build.properties to
instruct Torque to produce SQL that fully qualifies the object name
with the appropriate schema owner. Any advice you might offer will be
appreciated.
Best regards

- Java UML tutorialsThere's a good tutorial on UML with corresponding Java code at
http://www.parlezuml.co.uk/tutorials/java/class/index.htm
So far there's only one on class diagrams, but there's quite a few
much more advanced UML tutorials aimed at C# developers that this one
seems to be a "port" of, so expect more tutorials soon.

Now I found out, that it works, when I put the bin dir
of javac.exe to the Windows system PATH before running
Eclipse. I don't like that. Isn't there another way?
