- DataSource problemHi,
I would like to use javax.sql.DataSource to connect to the database from a
simple application.
I have the next program fragment:
Context initctx = new InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource)initctx.lookup(
"java:comp/env/jdbc/MyDatabase");
java.sql.Connection cx = ds.getConnection(user,password);
I do not know how what "java:comp/env/jdbc/MyDatabase" means and how to set
the database url, the jdbc driver and so on.
I have read many documents but I cannot find the solution. Can anybody help
me?

- JSP tags questionsI am VERY new to JSP, so I hope my question makes sense.
I am trying to use a tag from the google API estimatedTotal.
<google:estimatedTotal />
If I just put it in my jsp like this, it prints the number of
estimated search results directly on the page. I don't want this. What
I want is to collect this value and stick it into a java variable for
future processing.
Can this be done? If so, what's the syntax?
Thank you so much in advance

This was broken by the change to the dynamic plist. These files are
installed by the pkg-install script, which occurs after the packing list
has been generated :(. A simple fix should be to add an explicit
PLIST_FILES/PLIST_DIRS setting for these files. I suspect the breakage
for jdk15 is the same. I'll look into it.

- mozilla style sidebarG'Day All,
Would like to build a mozilla style sidebar for a java application.
However, before going off and reinventing the wheel, thought there may
be one in existance already. Google searching has not turned any up
yet.
Does anyone know of a good swing based sidebar ?

- Netbeans 4.0 beta2 color scheme configuration?I just downloaded Netbeans again (tried 3.2 and 3.3 way back when). At one
time, you could change the colors of the application (not *just* the
editor) with an XML file or use a custom L&F. I need to setup Netbeans to
be a much darker color scheme since the default one is *way* too bright and
very uncomfortable to use. I get a headache within 30 minutes of using it.
However, I've not had much luck getting anything to work (what little I
remember for 3.2/3.3 days). Any pointers would be appreciated.

- 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.

- 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,

- Getting the references of all the instantiated classes in my programHi All,
I want to do something like the following: Say I have an Auctioneer and a
Bidder class and then in my program I write:
a1=new Auctioneer(blah blah blah);
b1= new Bidder(blah blah blah);
b2= new Bidder(blah blah blah);
Is there a way I can get a list of references for the objects? I would
like to have an array with a1,b1,b2 as references. Is that possible?
I look forward to hearing from you soon.
Thanks,
Dil

- -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

- 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

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!

- 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.

- 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 ?

- 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

- 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.
