Sure, because it is the output of the comparision functionality.
Trouble is it is too broad, you only need three values, not two ranges
and a central value.
I put a wrapper interface (named "Sortable") around the comparision
functionality so that it would emit specifically -1, 0, or +1, as
manifest constants named LESS_THAN, EQUAL_TO, and GREATER_THAN, on which
I can then use a simple, symmetric, and clean switch syntax.
Given enumerations, that would presumably be even easier, because then
you could exhaust the enumeration type to the satisfaction of the
compiler, and wouldn't have to include a "default" switch case, the only
wart in my current setup.

helpful "poster-map" from sun:

I had to go to full-screen mode in my browser, otherwise the controls at

and navigate around.

- have tomcat run a c binary via cgiAnyone know how to make tomcat run an actual exe?
I'm using windows 2000.
I can get it to print the binary contents of the exe to the web page,
but not actually execute it.
The docs indicate that you specify an executable in web.xml where you
specify cgi and that the default is perl, but I don't need an
interpreter to run an exe.

- J2ME: allowing for "Allow HTTP traffic?" confirmation when doing a connection timeout mechanismI'm using threading in a J2ME app to allow a timeout on an attempt to
connect to server. However, I'm having an issue with the usual
confirmation the user gets on first connection attempt: you know, the
message that say something like "This application would like to send
HTTP traffic. Allow this?" The problem is that I have no idea of how
long the user takes to read this message before hitting "ok", so my
connection timeout could timeout before the user has even hit ok and
before any connection attempt has been made!
Is there any callback available so that I know when the user has
actually hit 'ok'?
My current workaround is to make a dummy first connection to a bad
address, e.g. "http://x", just to get the user to hit 'ok' and get that
out of the way before making my proper connection attempt.
Is there a better way though? This technique makes an attempted DNS
lookup which wastes a little time.
Thanks.
N.B.
I'm aware that in some cases the user can have a preference set so that
the HTTP traffic alert happens before *every* server communication, but
I'm ignoring this case for the moment.

- EJB Remote Calls - Serialization Restriction(s)Hi,
I have a simple HelloWorldApplication which uses SSbs.
I pass a Customer Object which has two attribute String name and
Address address;
I made Address not-serializable
so when i make calls to the SessionBean i get a remote Exception which
contains the not-serializable exception in WebPShere (as expected)
To my surprise this application ran without any problem in JRun4.0
Why would that be the case and what would the result in other APp
Servers like WebLogic be?
AFAIK, objects (parameters and Return types) must be serializable for
all Remote EJB Calls.
Note this applicaiton does not use Local Interfaces..

- Comparables and GenericsHow do I express "A Comparable that can be compared to itself" in generics?
I have a method that takes as parameter an array of Comparables.
Whilst trying to "modernize" this code, I can no longer write simply:
public void myMethod(Comparable[] primaryKeyValues)
but need to add "generic info" to Comparable.
The only requirement I have is that the objects should be able to run a
compareTo() on an instance of their own classes.

Well, no, it just takes perseverance. Being careful not to junk the

experience.

Indeed; in 30 hours so far, I've removed roughly 3500 emails either
containing the virus or saying they were forwarded with the virus
removed. This to my Unix ISP account, where mailx() is my friend and
companion for weeding through the end results of Microsoft's sloppy
coding practices.
Too bad California's refusal to allow the M$ denial of "fitness for
merchantability" cannot be reflected world-wide; a class action lawsuit
for damages would redistribute all of M$'s wealth and capital equipment
to the Internet as a whole.
Meanwhile, 200,000,000+ flawed email clients are trying to find my email
box with their virus copies.
Sigh; it is going to be a long next few days.

3) Copy (clone()) the Hashtable. Iterate over the copy. If you find an
entry in the copy that should be removed, remove it from the original.
Make sure that no other thread works the original Hashtable while you
enumerate over the copy and manipulate the original.

That should not be a problem as long as each one of them is listening on a different port and you have enough memory. We have an application that uses embedded Tomcat and I can start about 15 instances without any problem.

java-programmer, Eclipse Appearance Problem
Hi all,
I have Eclipse (version: 3.2.2) and JRE (version:1.6.0.1) installed on
my Windows Vista System. When I am working regularly with Eclipse I
encounter with disappearance of some regions of Eclipse window.
Specifically package explorer and console regions are becoming a white
area right after I switch(focus/bring to front) from another
application to Eclipse. If I resize the Eclipse window or just make
some mouse gestures over those white area, they return back to normal.
I have no idea about the problem so I could not goggled it. Here is a
screenshot: http://www.imagehosting.com/show.php/502707_20070421132840.png.html

Maybe it just needs a shave and a haircut. But for serious

looks .. <http://www.eclipse.org/newsgroups/>.

Now you have recognised the minor posting problem, I will add..
a) It is best not to top-post.

b) Good luck with the answers over on the relevant (Eclipse)

An interesting philosophical question. If a number is
rational it can be expressed as p/q, where p and q are
integers, q != 0. Therefore i is not rational.
However, it's not clear whether i is irrational or not,
since irrational also means "not rational", but I for one
would think that an irrational number is real, and i is
not real.
Also, there are at least two different ways of defining
a real number (Dedekind cuts and Cauchy sequences), and
neither can be used for i, since i is not part of the
total real ordering, nor can it be the limit of any sequence of
rationals, even allowing for silly claims such as -1 = 1+2+4+8+... .
(Briefly: if x = 1+2+4+..., then 2*x=2+4+8+... = x-1;
therefore 2*x = x-1 or x = -1, despite all partial sums
of the series being positive. But it's not i.)
On the flip side, though,
http://mathworld.wolfram.com/IrrationalNumber.html simply
defines an irrational number as any number which cannot
be a quotient p/q of two integers, but the definition is a
bit sloppy since it implies irrational numbers have decimal
expansions (though it has real and imaginary parts, which can).
This appears to be a "definitional bug".
It gets bizarre though, as i is an algebraic integer,
and a unit of the algebraic number field. (There are a
lot of units in that field, as opposed to the two units +1
and -1 in the rational field.)
So now we have a non-rational algebraic unit. At this
point it's probably best to head out for a coffee or
tea break as one's brain is probably screaming for aspirin
at this point. :-)
Followups to a slightly more logical discussion area. :-)

- Jmagick and rotating image.Hello,
I am using Jmagick to manupulate and rotate images. When I rotate an
image, it gets a white color where no image is standing (in the
corners). I already tried with convertImg.setBackgroundColor( new
PixelPacket(100,50,100,200) ); but the whitespaces stay... ...white. I
need to have those areas transparent. I am using
imgInfo.setColorspace( ColorspaceType.TransparentColorspace ); so it
must be possible. can annyone help me with this?
When using imagemagick commandline I get what I need by using -

I hope someone can help me.

- Azureus wont compile coz of 4E4D4554484F440E4350500525Hello people...
So, after dodging Azureus dependancies, this might be the final hurdle
to get Azureus to compile :/
Anyway... I got an internal error (4E4D4554484F440E4350500525)
I got that error when I was installing something called "sed"
(/usr/ports/net/sed ?), but that got resolved once I mounted
linprocfs...
But Azureus refuses to compile...
I googled further more and one site tells me to add -Xint to my java
command line... I added that in the last line of work/azureus file
that was created. And thats how the number of files mentioned in the
output below reduced from 2000 something to 1476... Good thing/bad
thing???
Any ideas how to get this working?

- Tomcat, creating threadsI am trying to do some thread profiling on a website that consists
almost entirely of JSPs. When I create a thread in my application, I
give it a relevant name.
The problem is, I am seeing other threads that are calling my classes.
Are these threads being created by Tomcat?
The "unknown" threads have names like: Thread-17, Thread-18, etc.
I'm not sure, but I think these threads are being created every time my
JSPs try to access a session. Is there any way to tell where these
threads are coming from? Or, if they are being created by tomcat, can
I tell tomcat to name them something different?
Thanks in advance.

- editing nodes in JTree, icon problemI have a JTree with a child node that has a dropdown list in it. When I
click on the node to make the list appear, then make a selection, the
icon changes to what looks like a document icon.
My problem is that the document icon stays there after I make the
selection in the dropdown list until I click on another node. It's like
the process of making a selection is unfinished.
Anyone know what that is?

- regex: How to extract substrings?This should be really easy, but I couldn't find it in the tutorials and
documentations on the web:
What is the Java equivalent to the following Perl operation?
my $entry = "__3432__Smith__"
my ($id,$name) =
$entry =~ m/__(\d+)__([A-z]+)__/;
In other words, I want to extract the number and the name from the
string $entry, using a regular expression.
I tried the following:
Pattern p = Pattern.compile("__([0-9]+)__([A-z]+)__");
Matcher m = p.matcher("__3432__Smith__");
while(m.find()){
System.out.println(m.group());
}
But that gives me the complete match at once, not the two subgroups that
I specified using the parens: (\d+) and ([A-z]+).
Who can help?
Thanks!

- Does my panel play hide & seek ?Hi,
In an application, that uses internal frames and the JDesktopPane! I
now want to add a pane to my application to the right side of the
window. But this pane should be hidden. In the sense when i click on a
button, it creep inside slowly and when i click on it, it should creep
out slowly again.
Is such a thing possible with swing? or is there any other way possible
for this?
