- right click menu not highlightingIm working with a jtree and I have added the jpopupmenu to the jtree
object.
When I right click a node the menu comes up appropriately, it even
accepts clicks and performs the appropriate action. The only thing
that isnt working is the right menu highlighting when I have the mouse
over the menu items...
Im wondering if there is some place in my code where I perhaps overrode
some code that would typically be responsible for highlighting the
right click menu... I implemented a little drag and drop functionality
for the jtree, could this be messing with the highlighting of the menu?
Thanks

- Short question about JSliderHi,
I have a problem with the font of JSlider labels.
This code compiles but does not work and I am wondering how I can set
the label font :
JSlider s = new JSlider(JSlider.HORIZONTAL,min,max,value);
Font f = new Font("Monaco", Font.PLAIN,9);
s.setFont(f);
...
Thanks for your help and suggestions

- Java and JSP to MySQL databaseDear all,
I am planning to build my web application with the following
architecture:
Redhat Linux 9.0 platform
Apache Tomcat Web Server
MySQL database
JSP with Java for writing the web page
But unfortunately, I encountered some problems in properly linking my
JSP to the mysql database. I have installed the JDBC connector
interface already.
I would apperciate if anyone can give me some hints on the proper set
up and configuring of the architecture.
Thanks a lot.

- Threads not running in starting order (?)Hi!
Below I do start Thread t1 before t2. t1 tries to call print1() on a
Printer object and t1 print2() but only the first will success since it
obtains a lock on the Printer object. I'm surprised that although t1 is
started first the code prints "2". If I put a sleep(5) between the
starting of the threads t1 wins the race.
Can somebody explain?
public class SyncThreadTest
{
public static void main( String[] args )
{
new SyncThreadTest().go();
}
private void go()
{
Thread t1 = new Thread( new Runner( 1 ) );
Thread t2 = new Thread( new Runner( 2 ) );
System.out.println(t1.toString());
t1.start();
System.out.println(t2.toString());
t2.start();
}
class Runner implements Runnable
{
int i = 0;
public Runner( int i )
{
this.i = i;
}
public void run()
{
// Printer p = Printer.getInstance();
Printer p = new Printer();
// synchronized( p )
// synchronized( Printer.class )
synchronized( p.MUTEX )
{
while( true )
{
System.out.println(toString());
if( i == 1 ) p.print1();
else p.print2();
try
{
Thread.sleep( 500 );
}
catch( InterruptedException e )
{
}
}
}
}
}
}
class Printer
{
private static final Printer instance = new Printer();
public static final Object MUTEX = new Object();
public static Printer getInstance()
{
return instance;
}
public synchronized void print1()
{
System.out.println( 1 );
}
public synchronized void print2()
{
System.out.println( 2 );
}

- Applet Canvas / Panel ProblemHello,
I have written a threaded tree control which is displayed in an
applet.
The way it works is that the reusable control is a canvas.
The control is created in an applet and the canvas is drawn onto a
panel.
Things work great when the content is static, however when the tree
structure
is changed - i.e. someone adds a folder or deletes a file problems
creep in.
I have no problem updating the tree (which is the canvas) but after
every change the new canvas needs to be placed on the panel.
I have tried
Panel.remove(tree);
Panel.add("Center", tree);
(there are three panels in total - the other two have scrollbars in
them)
But this does not appear to update when changes are made.
So I have tried
Panel.removeAll();
Panel.add("Center", tree);
Panel.add("South", horizontalScrollbar);
Panel.add("East", verticalScrollbar);
This does the update perfect however I get a flickerwhen the update
occurs.
So basically my question is in two parts?
Can anyone suggest how I can update the panel to avoid it flickering?
Or anyone suggest an alternative way of organising my tree so it
remains a generic control but has a better method of updating?
does that make sense?
Any suggestion greatfully recieved.
Regards
Lloyd

- Getting HTML title using HTMLEditorKit.ParserCallbackI am parsing an HTML file using ParseDelegator and a ParserCallback. I am
trying to get the document title and the HREF links. The ParserCallback is
successfully getting the HREF, so I know it is basically working. However,
when I try to get the title, I always get back null. Here is the relevant
code of the ParserCallback subclass. Anyone have any clue as to what I'm
doing wrong?
public void handleStartTag(HTML.Tag tag,
MutableAttributeSet attrSet, int pos)
{
if (tag == HTML.Tag.TITLE)
{
urlTitle = (String)attrSet.getAttribute(HTML.Attribute.TITLE);
System.out.println("attrSet: " + attrSet); // prints ""
System.out.println("found title: " + urlTitle); // prints null
}
if (tag == HTML.Tag.A)
{
// This successfully gets the target URL
String targetURLStr =
(String)attrSet.getAttribute(HTML.Attribute.HREF);
}
}

- TCP Keep Alive probesHi All,
I have a java client app and want to send TCP Keep Alive probes to my
server every 10 minutes as opposed to the default 2 hours. I see a
setKeepAlive() call in the API, but that only turns on whether you want
to send Keep Alives or not. How do i specify the Keep Alive probe
interval?
Thanks,

Presumably anyone who thinks that Rush Limbaugh is not The Voice Of God. :-)
Although in all fairness he more likely was referring
to those individuals who think, among other things, that
socialism/communism cures all ills, admires/admired Mao
Zedong and Lenin (*not* Stalin, who corrupted the notion),
and thinks that $100M/yr CEOs are obscenely overpaid.
(I've wondered, though: in a communistic economy, why would there
be any need of money at all, except for dealing with the other
countries? The existence of the ruble appeared to be a kludge;
of course now that Russia's capitalist, it's a moot point.
Not sure regarding the CEOs; I'd have to look. I wouldn't mind
$100M a year but I'm not a CEO...and I know which system works
better. If it's not obvious, look at N Korea and S Korea, and
then tell me which one's starving :-) . The weird bit is, the
US Prez only gets about *$400K*....)

- Regex GroupsHi,
I have a question concerning the behavior of regular expressions in Java. I
have a text: "text-123-234-535-235"
I use a regular expression to get the text: "text(-[0-9]*)*".
The problem is that I don't how many number blocks there will be. It can one
or twenty. Java only delivers me the last matched block as group. How can I
get all?
I can't use String.split because the regex is configued in a config file and
the regex can change as can the text. So the Java code needs to be flexible
what to do.
Is there any way to do this?
Thanks,
Andreas

I understand and sympathize with what you are trying to achieve, but I
believe you are barking on the wrong tree here. Eclipse on FreeBSD has
been in a rather good shape for at least the last two years that I have
been using it:
- The IDE port gets updated a few days or weeks after the official release.
- The various milestone releases from the development version are
usually ported as well.
- Many different plugins exist in the ports tree for Eclipse.
I also believe that people do get help when posting to freebsd-java
about eclipse and I'll make sure the same thing happens on
freebsd-ports. There are some things that could be improved however, like:
- Faster response to open PRs.
- More people working on porting the platform or the plugins.
- Official support from the eclipse.org site.
The first two are not going to be improved by a new mailing list, since
a mailing list by itself does not spark new interest on a topic. I'm
afraid that they may be harmed instead, since there might not be many
(or any at all) subscribers to that list that are also ports committers.
The way things usually work in FreeBSD-land for contributors without a
commit bit, is that you submit an improvement, try to get the attention
of a committer and then work with him through any details. The committer
attention is not something you get very easily, especially if you
consider how many lists these people are usually subscribed to.
Don't get me wrong, I will subscribe if such a list is created, but I
fail to see the need for it. Check out the archives of freebsd-apache,
freebsd-rc, freebsd-python and freebsd-perl for examples on the nature
and the amount of postings I expect we will get. Do we need a new list
for such an amount of e-mails?

java-programmer, Most Java apps are flawed on my system
I'm using a couple of free Java applications that easiliy outperform free native windows application. I'm very upset that those Java application share a common set of problems on Windows due to bugs in the Java libs and the authors are not willing to investigate and work around the problems. If I were a Java programmer I would probably send some patches to the authors or at least point to some resources but unfortunately I'm not a Java programmer. The reason why I post here is I hope to find some resources like code exmples that I can forward to the authors to work around the bugs. First issue is the Java applications save their settings in the root directory of my D partition.
D:\.entagged
D:\.LimeWire
D:\.Phex
Pretty much all Java apps got this all wrong because people get very upset if applications trash their system while they are supposed to write either xcopy style (windows power users prefer unanimously xcopy apps according to a poll I made because of the ultimate simplicity and transparency) to the startup dir where the application is located or to the user context as defined in Microsoft's design guidelines which would be 'C:\Dokumente und Einstellungen\Frank\Anwendungsdaten\' on my system and would translate to 'C:\Documents and Settings\Frank\Application data\'. Please note that the windows explorer wouldn't even allow to create a dir with preceding dot manually and no Windows user would want to use a name with esoteric characters, abreviations or casing. I've summarized the technical reasons for the problem here:
http://www.gnutellaforums.com/showthread.php?s=b443bdda9ec96e6db7a54aed0858e8f9&threadid=44579
The second problem is that strings like "ain't" are saved as "ain-t" in filenames, this is unacceptable for a MP3 tagger and for any other reasonable application, on top of that there are casing problems as well. Nobody is willing to work around these bugs, it appears they stop to read my crys for help as soon as they read Windows, am very disappointed about Java, I got a couple of GTK+, QT, wxWindows and XUL apps working here on Windows starting rocket fast, looking beautifully and working amazingly well, some of 'em much better than most native apps.
It's OK when a crossplatform app is a little out of the norm, I close the application and it's all good but messing with my files, folders and system is something I find very annoying.

stax

java-programmer >> Most Java apps are flawed on my system
This problem is most likely specific to your particular configuration.
The leading dot is very simply explained - it is the "hidden file"
denoter on linux and other unix-like systems. The fact that D: is
chosen seems to indicate that the java environment variable user.home
points to D: - this is not usually the case. Take a look at your
systems settings, you most probably at some point specified just that.
The replacement is not specific to java either, and definitly not done
by the standard libraries - however it is an accepted "good practice"
not to have these characters in names, since many command interpreters
will choke on them. The case problems you mentioned, similarly,
probably originate from the program trying to work around deficiencies
in some operating and file systems (such as FAT-based filesystems not
being case sensitive at all)
Long story short: You most likely have both a misconfiguration (the
home directory) at hand, and treat some features as bugs.

Of course it is as explained but my config makes sense no windows application would ever have a problem with that. It's a bug in the Java libs.

I know this but the point is I'm not using a Unix like system, Windows has still a desktop share > 90% IIRC so it's pretty pointless for a Java app to bother Windows users with Unix conventions.

Like I set Java determines it using the parent of the desktop dir using one of the many reg keys pointing to the desktop dir, this is dilettante as every other library uses the appropriate API call.

Maybe a Linux or Mac interpreter but certainly not a Windows interpreter. The songs below are two of the best soul songs ever recorded:
The Spinners - Could It Be I'm Falling In Love.mp2
James Brown - It's A Man's, Man's, Man's World.mp3
and this is what Java does with it:
The Spinners - Could It Be I-m Falling In Love.mp2
James Brown - It-s A Man-s, Man-s, Man-s World.mp3
That's ridicoulous.

As a VB .NET and Windows user I find case sensitiveness as esoteric as curly braces. The programmer told me it's a Java problem.

That's for sure not Java changing the names, but the creators of the
application simply trying to be platform independent. It might be
better if they check the platform and change behavior according, but
it's a lot of extra work generally just for supporting windows which
has it's own less restrictive way of handling stuff.

Java is not a windows specific language. You just happen to use
windows. If the programmer chooses a dot-starting name (probably
because of a unix background?), this is his right and privilege... why
does it bother you?

I would not rule out that there could be improvements to the way the
user home is determined, i don't know the process and so won't comment
here. If anyone can shed light on how exactly its done, please comment.

Take a good look at the configuration of your utility. Possibly you can
turn of this substitution somewhere.

While i certainly won't tell you what to feel about things, it
definitly is a FAT-specific limitation. IIRC there is case sensitivity
in NTFS (not too sure, however). The programmer may simply have lied to
you, or used some library without really knowing what it does.

Well, how should I say it? I am not surprised that the authors of the
Java applications ignore your change requests. If you (a) state you are
not a Java programmer, but (b) claim there is a bug in a Java library,
where (c) there isn't one (at least no one knows about such a bug,
except you) it is likely that you get ignored.

People often write Java applications, because *they don't want to target
Windows exclusively*. If you keep telling them they should target
Windows exclusively, I am again not surprised that they ignore you ...

Sure, the Windows API call which on Win98 returns C:\WINDOWS as the home
directory for each and every user?
> As a VB .NET and Windows user I find case sensitiveness as esoteric as

Well, the fact that your OS is very limited in that area doesn't mean
other OS' should be as crippled as well. Your lack of imagination is in
no way a problem of the Java library.
> The programmer told me it's a Java problem.
The programmer probably wanted to have you of his back and just told you
what you wanted to hear. Or you just heard what you wanted to hear.

If a Java function that is supposed to return the home dir does not return the home dir then it's a bug, how hard is that to understand?

Even if that would be true it's no problem since Win98 is a dead system and imagine how fast would a Java app run on a system that old.

On my windows installation the function that return the user home dir
(System.getProperty("user.home")) returns exact what windows define as
the user home dir (%HOMEPATH%). Do if you point it somehow at D:\, the
java program uses that one. On my system for instance, limewire stores
it settings in c:\Documents and Settings\myname\.limewire.
Ok, I agree that it should be in ...\Application Data following the
windows way, but again, it would mean writing loads of platform
dependent code which doesn't add anything to the functionality of the
program in general. I'd rather like limewire working smoothly then
trying to figure out where to store settings on each system.

It's because your desktop dir is within your home dir, my desktop dir is on another partition because all my data is on another partition.

I rather have a few features less if that improved the quality of features that are there because all features should have the highest possible quality, I don't like half baked applications.

Well, that's what I say, both java and the java application are doing
the job like it's meant to be. Storing the users settings in the users
home dir. All systems, including windows, don't allow normal users to
write data just anywhere on the system, that's the job of the
administrator. Now, I know that on most home windows systems the normal
user also has administrative rights, while on practicaly all *nix like
systems, the normal user just has write access in his home directory
(and maybe here and there an extra dir).
Application developers can not foresee all possible setups on all
possible systems, because there will always be a user with yet another
setup asking for yet another way to store the user specific application
settings.
I'm pretty sure there are non-java applications will store application
data in d:\Application Data on your system.

Bart

To summarize this entire thread, basically the programmers wrote a
program that behaved in a certain way, and you don't like the way it's
behaving. You called it a "bug", but actually the program is behaving
exactly the way the programmers intended it to behave in that respect. While
you might have your own definition of a "bug", under the definition that I
think most people on this newsgroup use, the problem with your software
isn't a "bug".
I advise you stop calling it a "bug", because it may confuse other
people. Also, some people don't like people who makes "false" claims of
bugs. See, for example,
http://www.catb.org/~esr/faqs/smart-questions.html#id264997 I don't agree
with the everything written on that page, but I'm just giving you this as a
warning that you might upset people by saying you've found a bug.
Personally, it doesn't bother me much.
Anyway, back to your problem. Here's what you can do:
(1) Live with it.
(2) Use a different program.
(3) Learn Java and modify the program yourself (Limewire is open
source).
(4) Convince someone else to modify the program for you.
Right now, it looks like you're going for (4), but it looks like no one
on this newsgroup has any interest in modifying the program for you. Maybe
if you offered to pay them, you'd get more positive responses.

If 'getProperty("user.home")' don't return my home dir which it doesn't then it's a bug, period.

%HOMEPATH% is what on your machine? If unset, all the poor program can
do is guess. It tries to do this in a way that fails in your one very
special case, but works fine in multiple versions of windows.
It looks to me as if you are actually complaining about the program not
doing what you want it to do - programs which work just fine for a very
large number of users. Do you really expect the writers to call you
beforehand to inquire about your one very rare specific setup?
Bottom line: Either make your home directory setting airtight (by
setting it explicity), or don't complain about the results of the
guesswork you force the application to do. ;)

getProperty("user.home") = D:\ // argh!
I've worked out the code in C# however and if somebody would translate it to Java I could finally try to submit a patch and we could end this stupid argument. I have doubts however the path will be accepted because reading the replies of all the application authors and all of your replies I'm thinking most of you guys are pretty ignorant about Windows.
private string GetSettingsDir()
{
if (Environment.OSVersion.Platform == PlatformID.Win32NT)
return Path.Combine(Environment.ExpandEnvironmentVariables(
"%APPDATA%"), Application.ProductName);
else
return Path.Combine(getProperty("user.home"), ".appname");
}

The ultimate choice of filename is the responsibility of the

If files are to be passed around between different OSes or if the
program is to work on many platforms the programmer naturally avoids
various characters that can't be handled on other OSes.
The beauty of Java and the Internet is that it works for everyone, not
just Bill Gates.

I just checked your assertion using the Wassup applet at

It displays the restricted user properties:

That is correct.

If you don't like what Java is using for your home dir, you can
override it, but not with HOMEPATH which is something I have never
heard of.

Everything in computers is a made up convention. If you don't know
the conventions or if you know different ones, they seem like
gibberish.
Unix predates windows. Confusion comes from DOS and CPU ignoring
Unix conventions seemingly just of the hell of it.
There this no inherent reason why you should use / or \ as a file
separator or : for the drive separator or even if there should be a
distinction between drives and directories. It is a bit like being the
inventor of the first car and trying to decide on right or left and
drive.

- Singletons and Serialization QuestionI am operating within Tomcat 6. I use 'collector' singletons to build
complex trees of objects from database queries. These singletons rely
on a pool of connections to various data sources, which are made
available via a 'connection pooling' singleton like this:
Connection
con=DriverManager.getConnection(MyPoolingSingleton.getPool("dbwrite"));
where "dbwrite" is the name of a connection that was established
earlier having certain permissions, etc.
My goal is to remove the 'collector' singletons to an app server and
obtain copies of them on a web server via serialization. They still
need access to the database after they are created. In this case the
'connection pooling' singleton must be instantiated locally on each
web server, since connections cannot be pooled across multiple JVM's
in my little world.
My question is, how to ensure the MySingleton.getPool() method call
points to the local singleton and not the singleton from the
originating server. Is it sufficient to ensure MyPoolingSingleton is
not serializable? Do I need to use a mechanism like a transient
instance variable to get a reference to the local copy of
MyPoolingSingleton?
Thanx all!

- Optional EJB2.x CMP many-to-one relationhipsIf I'm creating a CMP many-to-one relationship for an entity bean and that
link is optional, if the link is not active must I set a null value into
the field representing the many end of the relationhip?
For example, I have an Address entity bean that includes an integer
'RegionID' field. This field value is optional. I want to create a
relationship field that allows the Region entity to be accessed from the
Address entity. As the address to region many-to-one link is optional must
I set the default value of RegionID to be null?

- remote JBoss on local consoleI'm using Eclipse 3.0 IDE and JBoss 3.2.3 app server for building and
deploying EJB's. The Problem is that JBoss is on another PC and when I
deploy my bean the eclipse console shows only that my jar file is
copied to the server directory.
no debug , no error messages ...
so my question is how to make server debugging shows up on my eclipse
console

- EnumSet + contains: strange behaviorDear all,
The following example of EnumTest seems to be inconsitent with the
interface definition of contains: It executes the lines marked with
XXX, which clearly is an error. Does anyone have an explanation?
Thank you,
Ulrich
import java.util.*;
public class EnumSetTest
{
public enum EnumTest
{
ONE,
TWO,
}
public final void testEnumSet()
{
final EnumSet<EnumTest> result = EnumSet.noneOf(EnumTest.class);
if(result.isEmpty())
{
System.out.println("empty"); // enters this branch: correct
}
else
{
System.out.println("not empty");
}
if(result.contains(EnumTest.ONE));
{
System.out.println("error"); // XXX
}
if(result.contains(EnumTest.TWO));
{
System.out.println("error"); // XXX
}
}
}

- java slows down suddenly?hi..
for some reason the java in our aix suddeny slowed down, meaning only
application using it (like tomcat 4.18) were extremly slow. (tomcat was
listening on port 18080)
tomcat was laucnehd by the a wrapper who reported messages like pingin
jvm and not getting a response.
another tomcat listening 8080 on the same machine, did do well, but
it's the application servlet took forever to start.
the cpu and memroy of the machine are all free, so no worries there..
any ideas on what to search for?

- Create new object the MenuItem is pressedHello,
I have develop an application, but I am having som problems what
eventshandling when a MenuItem in a Frame is pressed.
/*
menuFileUpdate.addActionListener(new Update());
*/
In this code the Update-object is created when the main-program i
initalized. This i a problem - I would like that the objekt is created at
"pressing time". Do anyone god any suggestion to how this i done?
The update-objekt i an class implementes Runnable. This class is af
singleton with a static instance. What I do right how is to test if the
static object i null, and if is I create a new one, and start the thread.
How ugly is it to set the static instance= null when the job is done - and
thereby create thread-objects if the getInstance() is called?
Do it give any proformace to run the Frame in a thread calling invalidate,
and let the Update run in a the too?
Thanks,
Brian

- Problems Skewing Image (Trapezoid) with Graphics2Dhello!
right now i am working on a graphical output for a video projector. the
projection will be thrown on the wall from a little off center, so that i
will get the picture as a vertical trapezoid (the projectors i am using are
only able to correct horizontal trapezoids). my java program will have to
correct the effect. therefore i need to transform my graphics2d buffered
image NOT shearing the image, but genuinly skewing the image (that is two
parallel sides and two non parallel ones), as it would probably be possible
in java3d with the tilting of a plane.
how is it possible to skew rectangles with graphics2d?
thanks in advance!

Well, it might be a bit off. I am talking about 1986.

Seems about right.
So what version of msdos was around at that time? Obviously I didn't
use it!

It seems to me that I was using 3.x. Maybe it was 3.1? I seem to
remember an earlier major ... was there a 2.8 or 2.9?
> not sure what you mean by "Sun 360"--a Sun 3/60, maybe?
Seems likely. I recall it as a Sun 360m. "Monica" by name, following
the cpu serial number, mncaxxx (or something close). "Sun 3" definitely
rings a bell.
