- JProgressBar Flickering!Hi everyone! I just have a little question here!
I have a Swing GUI in which I put a JProgressBar.
I also have a static class where I put a static variable JProgressBar.
In my main program, because the static methods are time consuming, I
start a new thread, where I initialize the static JProgressBar with the
one in main gui.
So I'm able to update the text, value, etc in the GUI without locking
my main program.
The problem is:
I put progression report [ progressBar.setValue(int) ] in my loops to
see the change. It works perfectly BUT!!!
Every time it sets a new value, the progress bar show a lot of
flickering! I enabled double buffering on it, but no effect!
How can I remove this bad effect??? If some knows please tell me quick
:)
Thanks,

- PAAppViewer3 (AppViewer3)?Hello,
Might anyone please kindly answer my question? Thank you very
much.
I can't read the result of performing bootstrapping in Amos 6.0.
In the Amos text output, on the left hand side, there are two
sections. The lower section is the result of performing bootstrap,
including estimates/bootstrap, estimates of bootstrap standard error,
estimates of bias-corrected percentile method.
However, I can't read any of them. Nothing shows up.
Also, I find this message,
Error number: 70
Source: PAAppViewer3 (AppViewer3)
Description: Permission denied
Call stack: frmMain hdoc_ onmouseover
How can I be able to read the result of performing bootstrapping in
Amos 6.0.?
Thank you very much and look forward to your kind reply.
Please take care
Best wishes to your life

Taeocrp announces breackrough in removing deadly l andmines.
Mill Valley, California August 25, 2006 - The Alliance Etnerprise Corpoartion announced today a breakthrough in developing an Areial Lnadmine Sysetm aimed at locating, detecting and mapping deadly landm ines.
TeaCorp's mission is to reclaim lands around the globe embedded with l andmines that victimize countries and their stakeholders.
More than 100 m i l l i o n landm ines in 83 countries are holding international communities and industries hostage, preventing the inv estment in and development of product ive lands and the re-building of infrastructure. A broad variety of landmine s have been scattered over pro ductive areas effectively crippling the eco nomy and disabling thousands of children and adults. There are no reliable records that accurately show where these d e v a s t a t i n g landmine s lie in wait for their v ictims.
With the present day c osts to clear a single land mine ranging between $1,000 to $1,500, solving the problem of de-mining lands will reach billions of dol lars. TaeCorp has developed a technology based, cos t effective solution to this problem using its three tiered approach to scanning, mapping and removing la ndmines. TaeCorp's System will provide many social and eco nomic benef its to countries and their industries including oil and gas, mining, agriculture, roads and infrastructure development.
About TaeCorp.
TaeCorp's vision is to be the recognized leader in providing Aeiral Deteciton Systmes including global de-mining, clearing a path to a safer planet for all humankind.
Here comes the big one!

- Nunni FSM Generator v. 1.1 released!NunniFSMGen v. 1.1 has been released on August 12th 2004
NunniFSMGen is Open Source and comes with GPL license.
http://nunnifsmgen.nunnisoft.ch/en/home.jsp
NunniFSMGen is a java tool that starting from a transition table
generates the corresponding FSM (Finite State Machine) in Java, C
or C++ source code. It has been developped in 2003 at NunniSoft
for generating the FSMs of our own software and successfully used
(here at NunniSoft) since it's first internal release (in June 2003).
Changes since 1.0.3
- generation of C code is now more optimized for size
- some clean up
NunniFSMGen has also been used to develop two other Open
Source projects, distributed under the LGPL licence:
NunniMJAX http://nunnimjax.nunnisoft.ch/en/home.jsp
and
NunniMCAX http://nunnimcax.nunnisoft.ch/en/home.jsp
The above are two minimal and lightweight libraries for
parsing XML. The first is written in Java, the sencond in C.
Best regards.

- Proposal. Sort should return a boolean.Here is an idea. I would like it if Collections. sort and Arrays.sort
would return a boolean. true means something actually changed. false
means the array was already in order.
Further there would be an additional boolean parameter to the sort to
say "items probably already in order". The sort would then do a quick
check to make sure the items were in order, and if so, bypass the full
sort.
This would be useful when you have to avoid needlessly calling
fireTableDataChanged after a sort.
It would also allow you to use sorts in an assert to ASSURE the data
are already sorted, and explode if they are not already sorted.
Since the sort is void now, all existing code would still work. You
would just have an additional method call with the optional boolean
parameter, or perhaps only in would get the boolean return.

- -Xmx---m getting smaller and smallerHi,
I have Windows XP SP3 with 4GB memory (I know Windows only allows apps to use
about 3.25GB.) I have no applications running. I ran System Mechanic 7 to
defrag the memory with the result of the largest contiguous block of memory
being 2.74GB.
However, everytime I started Eclipse 3.3.2, the JRE 1.6.0_04 JVM terminated
with a -1 code. I started at -Xmx1024m and continually decremented until I
reached -Xmx600m when Eclipse started okay. This morning I was running
Eclipse with -Xmx900m okay.
The only changes I made were to (1) set the system variable JAVA_HOME to
reference JDK 1.6.0_04 and replaced java.exe, javaw.exe, javaws.exe in c:
\WINDOW\System32\ with the JRE 1.6.0_04 files. They were 1.4.2_07.
Does anyone have any idea why the JVM terminates because of not enough memory
when there is more than enough contiguous memory? This is really
frustrating.
Thank you,
Don

- Something a bit goofy about Generics
Iterable<? extends JavaFileObject>
You'd think a JavaFileObject[] or a JavaFileObject... would fullfil
that requirement, but it doesn't. It fills it sufficiently to do a
for:each but not to satisfy this parameter.
That is like a piece of purple lint on a white sweater.
People say arrays and generics don't mix, but they damn well SHOULD.

- Printing EPS (embedded postscript) from Java.
Hello all,
I need to print .eps (also called .epsf, .epi, .epsi) from inside a
java program. My target platforms are windows and mac-- although
windows is first.
The new 1.4 printing API has aupport for printing normal postscript
but does not have .eps support.
I've been looking around the internet to see what solutions people
have come up with and unfortonately I didn't get what I would call a
solid answer by doing this....
I looked at the source of two open source programs the support .eps.
They both have origianal source but esstenially did it almost exactly
the same way. They took the .ps file the the standard Java classes
generated and just stuck an .eps header on it. They then stick the .ps
inside a box as required. They then searched the .ps file for commands
that are illegal in the .eps and if they are there they just die.
I've got some serious problems with this:
(1) It assumes that the Sun classes are going to generate a .ps that
is easily converted to an eps. Maybe they do now but what about future
versions of Java?
(2) It makes big assumptions about future .ps and .eps formats.
(3) It stinks of just being a hack. Does anyone really know this is
going to work all the time and on all platforms?
Does anyone have any experience with making .eps from Java that has
any sugestions? I want to translate my Garphics2D objects to .eps. I
want the .eps to be accepted by major publishing programs on windows and
mac.
Thanks

- Swing Worker Pause/ResumeHello all,
I am dealing with a class that extends SwingWorker and Inside that
class there is another class defined. I'll refer to the inside define
class as the "helper class" for sake of clarity.
What i am try to do is to pause/resume the class that extends
SwingWorker, when i used flags to do that it outputed errors from the
"helper class". These errors came from a method that fires Custom
Events and they were NullPointerExceptions. After the errors were
printed the classes continued executing.
How can i pause/resume successfully ?
Thanx in advance for any help :D

- JTable(A few more queries )I had a couple of more queries -
1) how to prevent swapping of the columns as in, by default the columns
in the JTable are not fixed in terms of their placement. They can be
very well swapped with one another. I want to prevent this.
2) Also after feeding the JTable with the data in database, i want to
be keep one row always empty so that a row can be inserted. It's like
we have in MS-Access.
hope i was clear in explaining the query properly.
Thanx,

- Applet using jdbc (ms sqlserver)Hi,
After reading lots of docs, a got the impression that it is possible to
write an Java Applet, that uses jdbc to connect to MS SQLServer (Without
flushing all security permissions down to drain).
Here is what I've done:
1. Downloaded the Microsoft JDBC driver for SQL Server 2000 SP 3.
2. Downloaded the app from Microsoft's site:
http://support.microsoft.com/default.aspx?scid=kb;en-us;313100
3. Tried to compile.
I get the java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for
JDBC]Error establishing socket.
I have tested every possible error that I can find in MS's site. I have
tried to alter policies granting "permission java.net.SocketPermission",
with no luck. I think that before granting this permission, I also got
some security exceptions..
So here's my question: is it possible to create an applet (UnTrusted)
that uses SQL server, that can be run in browser, that doesn't need any
security alternations?
Best Regards,
Mika

- how to do synchronization profiling and RepaintManager and performance issuesSome day ago I've posted about a problem with
javax.swing.SystemEventQueueUtilities.queueComponentWorkRequest
and some performance problem.
(http://groups.google.com/group/comp.lang.java.programmer/browse_frm/thread/afcd152d02c4d4cb/#)
My doubt is that the system spend too much time in symchronization
problems.
Someone suggested that it can be all the repaint stuff, but I've tried
to reduce it...(the paint component method in the reduced version is
something like
{ super.paintComponent..
draw an oval}
while in the complex versions is {
{ super.paintComponent..
draw 400 lines
draw 400 oval
}
and the first one takes the 20% of resources while the last the 40%
Moreover the time spent in the paint method is less and the repaint
manager should be decoubled from the component...
so how can I do a better profiling of the system?
I was thinking to override the repaint method and using directly the
invoke later paint..
but I'd like that the new method would be able to merge more call to
repaint in only one paint.. if the last paint hasnt stopped...
I hope that this info will sufficent, otherway askme
Thanks to all

- Programatically deducing VARCHAR2 length?Hi,
I'm using WebLogic 5.1 sp12 and Oracle 8.1.7 with JDBC 1.2 drivers.
I was wondering, if I know that a column is a vARCHAR2 column, how
could i deduce the maximum length of that column, short of repeatedly
inserting larger and larger strings until I genertae an exception. I
know with SQL*Plus I can describe the table and find out lengths that
way, but I was hoping for a more general automated method.
