- trying to fix oneTouchExpandable button size in JSplitPane's dividerThe BasicSplitPaneDivider class uses some custom-painted buttons for
the oneTouchExpandable buttons on the divider. Trouble is, they're
effectively hard coded to a fixed pixel size (final static int
ONE_TOUCH_SIZE = 6). At 144 dpi, that's really too small to use
comfortably.
I really don't want to subclass all the assorted JSplitPane pieces to
fix this and am hoping there's another way.
I tried scaling the Graphics2D in the paint() of a containing panel
and then of JSplitPane directly, either way the UI gets out of whack -
components don't get placed correctly, the divider drag hotzone
doesn't line up with the divider visually, etc.
Am I approaching the scaling wrong or is this a dead end? Other
alternatives?

- JTextComponent questionI have a Paste method that will take in a JTextComponent. I am passing
either JTextField's or JTextArea's. I need to do something differently
based on a JTextArea.
I have no problem determining if I have a JTextField or a JTextArea. The
problem I am having is that I need to know which JTextArea component I
have. What is the instance name of the JTextArea.
Example say between these two..
JTextArea jTextAreaA
JTextArea jTextAreaB
I have tried some reflection. What could I be missing?
private void paste(JTextComponent target)
{
final String method = "paste(JTextField "+target.getText()+" ): ";
if (DEBUGMODE )System.out.println(_Debugheader+ method);
appUtil.setStatus(jStatusArea, _readyMsg, _READY);
try {
Clipboard cb = Toolkit.getDefaultToolkit().getSystemClipboard();
Transferable content = cb.getContents(this);
String s = (String)content.getTransferData(DataFlavor.stringFlavor);
target.setText(s.trim());
} catch (Exception e) {
appUtil.setStatus(jStatusArea, _errorMsg, method + " " + e);
}
if (target instanceof JTextArea) {
//
// if jTextAreaA
// do something
}
}
Thanks in Advance...

- [Sizing: Tomcat 4.1.x] Memory Usage for the Session TrackingHello all,
i'd like to know how much memory the application server
have been used for tracking a new session.
i've tried the jProfiler from the ej-Tech however i found
seems it don't have an easy way to calculate the total
amount of memory the related object instacnes used for the
session tracking. i guess org.apache.catalin.session* is
the point to start with, however, to me, it's a little too
hard.
do anyone of you have did this similar thing?
say, to calculate the total amount of memory used, when a
browser visit a particular page, and the server create new
sesssion related objects and return the browser a new cookie
with 2 attributes initialized? e.g., name="matthew", sex="M"?
thanks a lot in advance.

I'm not talking about running; I'm talking about making a copy of
Eclipse and a copy of Kaffe and putting them both on an end-user's
system such that when I type "eclipse" I get a program made out of
both.
But you can see that it's not mere aggregation, because they invoke
each other when run.

- Server vs Client validationOn Fri, 30 Jul 2004 11:52:25 +0200, Rogan Dawes <email***@***.com>

In email, Rogan brought up the issue of what servers have to do to
revalidate Strings.
I mentioned earlier if the String must have one of a fixed set of
values how you can convert that to a country-index, state-index etc.
Then all you need do in the server is bounds check on the int.
For general strings, in DOS Abundance I categories characters as
numeric, alphabetic, lower case, upper case, accented, printable,
space, control char.
You can declare that a string can only contain certain classes of
character. That gets automatically checked on a keystroke basis, and
automatic conversion sometimes happens to lower case, to upper case,
or to strip accents.
If you had a similar facility in your client level validation, you
have to repeat it in the server. You don't need to deal with
translation, just validation, since any missing translation is clear
fraud.
Sometimes strings are combos of words, e.g. a list of fruit names from
a fixed list of fruit names. These can be converted to int bit masks.
The server does not need to validate these at all, just mask off any
unused bits.

- javaw?Hi,
I can't find any documentation of this, but perhaps I'm not
looking in the right place.
OS: We're running on Windows XP.
I've got some Java code that's being called from a
C++ executable via CreateProcess().
The command line argument works out to be,
javaw.exe -Xmx512m -jar foo.jar
I've looked in the online documentation and searched
on the net, but haven't found any documentation that would
allow to figure out what's going on here.
Can anybody point me in the right direction?
TIA,
Gerry Murphy

- javaw.exe - Xrs -jar my.jarAs I understand when Java program started this way it should ignore user

When I logoff from system application exits , what I'am doing wrong ?

- Javascript : formname.body.value.length == 0 validationHi,
We have a J2EE application which had jsp's that represent a form. When
we submit the jsp's the form is converted into a mail and is sent using
a mail server.
In the jsp there is a validation where we check for the length of the
body using the following:
if (formname.body.value.length == 0)
{
isFormComplete = false;
}
Need to know which are the possible cases when the length of the form
could be '0'.
The behaviour is real weird. Roughly 2 out of 10 times the length comes
as 0 even when the user enters all the details. What could be the
reason for the same ?
Any pointers are highly appreciated.
Regards,
Parag

- Socket functionality on jre 1.6.0 beta b59g
OK, it seems that on Windows XP Pro, that Socket has changed significantly,
breaking lots of my code.
Using "localhost" no longer appears to work to create a Socket object
on a port. Have to use "127.0.0.1" instead. Other aspects of Socket
also appear to be flaky/changed... I can certainly "ping localhost" so
it's not that localhost has a problem.
Can someone please explain the plain Socket changes for this new 1.6 ??

- cloudscapeI'm a newbie in cloudscape (Java too) and I'm having a problem. I've
followed the tutorial that comes with cloudscape to the letter. Everything
worked as advertised up untill this program:

- Change listbox mouse selection to not use ctrl keyI'm converting a program from Windows where the LBS_MULTISEL option allows
selecting rows in a table with a single mouse click. On the other hand,
with Swing you need to hold down the ctrl key and then it's buggy,
seemingly requiring rows to be clicked from top to bottom.
If there's an example of changing the Swing behavior, I haven't found it.
I've made some progress figuring it out but can't spare much more time.
Anyone know of a working solution? I can't be the only one needing it.
I can post what I've tried so far if a ready-made solution isn't available.

- HELP needed: Small Java applet I need a graphic Java applet that makes the following steps:
Given a circumference of radius "r",
Draw onscreen, say, 20 random radius.
Then, every time you press a button:
Rotate the 20 radius a given random angle (same for everyone).
Draw the new radius onscreen.
Note: The radius endpoints should be stored in float arrays and drawn as
float. (Of course one of the endpoints of every radius would be the center
of the circumference.)
I'm not very good at Java at the moment but I'd like to transform an old
program from QBasic into a java applet and I think that this little
framework is all I need. What I am getting at the moment is a lot of
compilation errors I don't understand.
The program I want to transform is here:

- Creating tiled image from multiple tiff sources in JAIHi all,
My situation is as follows. I have a number of tiff files containing
adjacent tiles which I would like to combine into one image. Currently I
achieve this goal in the following manner using the Java Advanced Imaging
library:
1) Create a target TiledImage with attributes appropriate to hold all tiles.
2) Load each tiff file into a separate PlanarImage.
3) Get the Rasters of each of these PlanarImages and translate coordinates
according to the rectangle they must occupy in the target TiledImage
4) Invoke TiledImage.setData(Raster) with the translated raster for each
tile
This works ok, but it does not seem to take advantage of the JAI's
pull-model; image data is loaded into memory immediately, probably as a
consequence of the call to getRaster(). However I wish to defer the loading
of image data into memory until it is needed, because only a subset of all
tiles are two be displayed at any one time.
I hence believe I need something along the lines of the NullOpImage class.
Unfortunately, the constructor for this class only takes a single source,
while I need to be able to pass a source for each tiff tile. One solution is
to subclass NullOpImage (or its superclass, PointOpImage) and take care of
things myself. Is this the way to go about it, or is there a better and
easier solution?
Any suggestions will be greatly appreciated.
Regards,
Michael.

Btw I have heard Eclipse has a C++ plugin, would it be possible to get
that into the port collection?

- Struts, Spring, ... what about Swing?So many Web frameworkings seem to have sprung up but are there any
really good frameworks for fat clients using things like Swing?
I am most interested in how the server side objects interact with Swing
components, the design patterns behing client/middleware/server/db apps
etc.
thanks

- renameTo for Directories on SolarisI've been attempting to rename a directory on Solaris 8 and continue to
have problems.
I read other threads that mention it is not possible to do when moving
between partitions on Solaris, but I am renaming to the same
paritition.
I am basically attempting the following:
File oldName = new File("/opt/OldDirectoryName");
File newName = new File("/opt/NewDirectoryName");
if ( oldName.renameTo( newName ) )
// Successfully renamed
else
// Failed to rename
For some reason I seem to continually be unable to do this.
Any ideas?

- client server communication in java I have a java web service that returns byte arrays to the client.
First a byte array is returned and the server gets the acknowledgement,
then the next byte array is sent and so on. But I don't have much idea
how to implement it. How can I resume from where I stopped at the
server side? Can anyone give me some idea so that I can proceed?

- EnterpriseBean and finalize()Hi Everyone,
I'm trying to learn EJB and picked up a copy of the book "SCBCD Exam
Study Kit" by Paul Sanghera. Inside it, I came across the following
sentence, which piqued my interest because I cannot see a) where this
can be found in the EJB 2.0 specification (actually, I was looking in
the J2EE 1.3 specification), or b) why finalizing a bean would be
interfering with the responsibilities of the container. Here's the
quote:
"... the bean class must not have any finalize() method because by
doing this you would be stepping on the container's toes, since it is
the responsibility of the container to manage the lifecycle, threads,
garbage collection, and so forth."
If anyone can shed a little light on this, and dispel the confusion,
I'd really appreciate it.
Many thanks,
Jono

- Regex syntaxI have managed to form the regex for the following two:
CTL = <any US-ASCII control character (octets 0 - 31) and DEL (127)>
String CTL_REGEX = "([[\\x00-\\x1F]\\x7F])";
LWS = [CRLF] 1*( SP | HT )
String LWS_REGEX = "((\r\n)??( |\\x09)+?)";
However, the following stumped me for hours.
TEXT = <any OCTET except CTLs, but including LWS>
String TEXT_REGEX = ...... // help me out please.

- Which IDE to choose (more specific than earlier, very similar post)?Hello guys,
I'm C++/Windows programmer and I'd like to smoothly switch to Java. I read
replies to earlier, very similar post, but I didn't even hear about such
IDEs :-(
My question is following: using what IDE can I easily create applets with
controls like edit, list, combo boxes, buttons, tree controls and - this is
very important - have support to draw 3D graphics? Some time ago I was using
Borland JBuilder, but I guess it was not intended for building commercial
releases. I was browsing Sun Microsystems' site and found free "Sun Java
Studio Creator, Early Access". Can I create in it commercial applets using
features that I described above? If not, please advise me something free or
really good enough (read: easy to develop applets) to spend money IDE;
preferably free of course :-)
Generally I focused on "Sun Java Studio Creator, Early Access", but I'm
waiting for your replies.
Please reply, your opinion is crucial for me.
Regards
P.S. I'm not going to create server-side applets. I will be doing applets
run in web browser.

- converting between double and integerI have a variable declared as a double as :-
sValue = Math.floor(Math.sqrt(polynomialDegree));
where 'polynomialDegree' is an integer.
How do I convert 'sValue' to an integer?? I cant declare sValue as an
integer straight off because its returning an error message saying 'possible
loss of precision', and have tried to convert it to an integer using
intValue() but keep getting an error saying 'double cannot be dereferenced'
Where am i going wrong?
Thanks

- How to detect existing text tables in a hsql db?I have a Java-Application that creates several text-tables at the first
start. When I start the application again I just want to check, if the
text tables exist. But the application always returns a "false, table
does not exist" and the localdb.properties and localdb.script files are
written new. After that, the tables can be detected, but only until the
next start of the application.
dbcon.connect(LOCALDRIVER, LOCALPROTOCOL, LOCALDATABASE, LOCALUSER,
LOCALPASS);
DatabaseMetaData metadata = dbcon.con.getMetaData();
String[] aTyps = new String[]{"TABLE"};
ResultSet result = metadata.getTables(null, null, "%", aTyps);
while (result.next()) {
System.out.println(result.getString("TABLE_NAME"));
}
result.close();

- Newbie Question - ArrayLists and methodsHello all (again),
My problem here is that I'm trying to build a list of ArrayLists that
hold data and I want to add the newly derived data into a table where
it's dependent on the first row. A short version of my program to
illustrate what I mean:
import java.util.*;
public class MyProg2 {
public static void main(String[] args) {
List table = new ArrayList ();
List <Integer> data = new ArrayList <Integer>();
data.add(1);
data.add(3);
data.add(4);
table.add(data);
System.out.println ("table(0) = " + table.get(0));
ArrayList <Integer> newNode = new ArrayList <Integer>();
newNode = createNode((ArrayList)table.get(0),0);
table.add(newNode);
System.out.println ("Added in a new row and table is now:");
System.out.println ("table(0) = " + table.get(0));
System.out.println ("table(1) = " + table.get(1));
} //end main driver
public static ArrayList createNode(ArrayList items,int lParen){
int a = 0; int b=0; int c=0;
if (items.size() >= 2){
a = Integer.valueOf(items.get(lParen).toString());
b = Integer.valueOf(items.get(rParen).toString());
c = a + b;
items.remove(lParen);
items.remove(lParen);
items.add(lParen,c);
}
return items;
}
}
(I'm unable to get rid of all the unchecked msgs because putting the
<Integer> tag sometimes made the program uncompilable. Use --nowarn
when you compile this program. :)
Iin this code, row 0 of table is changed in the method while it
creates row 1, but I don't understand why and don't know how to keep
it from changing. From this behavior, it's leading me to believe
ArrayLists are passed by value or is this the way of ArrayLists? I
thought parameters were passed by reference? What am I missing here?
