So, do you mean to imply by this that you've never used vim or gvim?
Just asking.

Presumably true of gvim, since it allows a lot of operations to be
done using a mouse.

It seems to me that the actual operations involved in editing
text files haven't changed that much -- find, insert, delete,
etc. -- so a program that was able to perform them with a primitive
interface should be equally capable of performing them with a more
sophisticated interface, and the fact that the underlying code has
been in use for many years might improve the odds that any bugs
have been found and fixed.
I repeat -- have you ever used any of these tools you're slamming?

So apparently you've changed your mind about "CUA" being a
cryptic term?

Well, when Mr. Gates (?) was saying that, I was probably still
mostly ignorant of the PC world; I started out on mainframes,
and it took a long time for me to regard PCs as anything but
toys. (Then again, I think one could make a case for the idea
that the way most people use them these days *is* as toys.
But I digress.)
I do pine for the days when more people believed in the Unix idea
of tools being simple programs that did simple jobs well [*] and
could be combined under the user's control to do more complex jobs.
But -- "yeah well".
[*] Rather than attempting to do everything the programmer and/or
the marketing department can think of, with mixed success.

- Positioning dialogboxes created with JOptionPaneThe dialog boxes created using JOptionPane like showConfirmDialog,
showInputDialog gets displayed in the centre of the screen. I need to change
its position. How to do this?
These methods return int or none.
How to get access to the dialog boxes so that they
can be positioned by using appropriate method? or I need to create a custom
dialog box so that they can be positioned?

- SOLVED: How to read MANIFEST.MF from pluginHi,
here is a way to access "your" manifest, i.e. the manifest of the jar
your class is loaded from. It only works for SunPlugin. In other cases
you may have another ClassLoader not supporting a public
findResource-method. The always public getResource unfortunatly
prefers to return resources returned by the parent's getResource if it
is not null. That's why you would get the manifest of rt.jar. Is there
any good reason to revert the principle 'local hides global' in case
of getting resources? Anyway, here it is:
import java.util.jar.Manifest;
import sun.applet.AppletClassLoader;
...
AppletClassLoader cl = (AppletClassLoader)
getClass().getClassLoader();
URL manifest_url = cl.findResource("META-INF/MANIFEST.MF");
Manifest manifest = new Manifest(manifest_url.openStream());
Yours,
Albrecht

- Text Field InputI have a JFrame where I hold visible only and employee ID number. I
can input the employee number, retrieve the employee information from a
database, and then display the information on the screen.
I then want to enter hours on the same form. I can bring the
appropriate text field visible, but can't seem to get the code to halt
execution in order to input hours and then compute payroll.
How do I bring a new field visible and then halt code for the input,
several times, on the same form, bringing only the appropriate fields
visible as necessary?
Hope that made sense.

- Applet no longer works in IE - problem fixedHi Andrew,
It seems that the source of my problem is the fact that I upgraded
from Eclipse 2.1.1. to 3.2.0. After testing with the latest working
version of my applet I found out that the compiler compliance setting
has to be 1.3 for the applet to work in IE. Default setting is 1.4.

thanks, Mark.

- making indented XMLI could swear that this used to work for me, but when I run the
following code I get:
<?xml version="1.0" encoding="UTF-8"?>
<a><b><c/></b></a>
which is not the:
<a>
<b>
<c/>
</b>
</a>
that I want and was expecting. I'm running JDK 1.4.2_03 on W2K with
the latest Xalan and Xerces.
I've tried running it like the following:
java -classpath .;xercesImpl.jar;xalan.jar;xml-apis.jar PrintTest
java -Djava.endorsed.dirs=. -classpath
.;xercesImpl.jar;xalan.jar;xml-apis.jar PrintTest
java -Xbootclasspath/p:xercesImpl.jar;xalan.jar;xml-apis.jar
-classpath .;xercesImpl.jar;xalan.jar;xml-apis.jar PrintTest
I'm at a loss here. Can somebody throw me a bone?
Cheers.

- To class or to methodI have a class
public class CascadeAction {
...
public CascadeAction(JDesktopPane ... ) {
}
...
public void setIgnoreIconified(...) {
...
}
public void actionPerformed(ActionEvent evt) {
...
}
...
}
Instead of having a class, is the proper way to create a method :
public void cascadeFrames(JDesktopPane desktopPane, int layer, boolean
ignoreIconified) {
...
}
I don't think I should place this method in a subclass of JDesktopPane
since doing so will make it impossible for other users to use the
cascade feature if they already have their own custom JDesktopPane.
Please advice me on the proper way.

It's all about how you want to use your time. I could use my time learning
lots of different tools and editors or I could find a handful of tools and use
my time to look at new apis/languages or work on open source projects, etc.

It's all about how you want to use your time. I could use my time learning
lots of different tools and editors or I could find a handful of tools and use
my time to look at new apis/languages or work on open source projects, etc.

Comments? Javadocs?
There are times when I want to capitalize or change from lower to upper or vice
versa.

Sorry, but this is going to be one big long run-on sentence:
Uusually when I want to change the capitalization in a comment or
JavaDoc, it is only one character that I want changed -- e.g. the first
character of a sentence which was mistakenly not capitalized (perhaps
because I had let go of the shift key too early or something) -- OR it is
that I had not yet broken my habit of capitalizing all the characters in an
abbreviation -- e.g., where KB stands for Knowledge Base and ID stands for
Identification, naming a methid getKBManagerUserID() instead of
getKbManagerUserId(), which requires an understanding of the English
language to recognize word boundaries and so probably could not be done via
a macro.

Odd.
I grew up speaking both English and German. I have never been able to
speak English with a German accent, or German with an American accent,
though I can definitely recognize it. I think my mind has mapped the
sounds to the languages, and I can't produce them in the "wrong"
context.

The standard editor at my last job was SlickEdit. I couldn't stand
it. It seemed to love corrupting the tags database, among other
things. But the real reason I abandoned it was that its vi emulation
mode didn't emulate well enough.

I'm pretty sure there *is* a vi plugin for eclipse. It's not free in
any sense, and I haven't tried it, but maybe it does what you're
describing.
I have been burned by supposedly 'vi compatible' modes so many times
that I am loathe to spend money to try it.

As opposed to opening a browser, loading the javadocs, looking up the
type, and *then* selecting a method from the list, copying and pasting
it.
I agree that the javadoc approach is slower; it's not clear to me that
it really forces any more learning.
I think my difference of opinion stems from my belief that motivated
individuals will learn; unmotivated individuals won't. It's possible
you could claim that Eclipse and other high-powered IDEs can act as a
crutch, allowing individuals to crawl along who might give up if they
were forced to use more basic tools. Of course, you could use the
same argument to support the idea that all programs should be written
in assembler, or maybe machine code.

I agree that anyone who works with Java should have those skills. I
don't think that means that we should eschew more powerful tools.

One of my professors claimed that she never had problems with carpal

I personally find that using a mouse hurts my wrist pretty quickly; I
use trackballs whenever possible, and even then try to do most things
by keyboard, with a wrist pad.

Absolutely!
The self-righteous "do it yourself" answer is too myopic in this case.
Programming isn't typing. It is about doing a lot of things at once,
and typing is among the least important of them. Even if a programmer
has to wait a couple seconds for code completion -- and obviously could
have just typed the identifier name in that time period -- the task of
writing code is going to be far more sustainable if that time can be
used for thinking, resting, relaxing the wrist, or whatever.

I'll admit that for many years, I avoided Eclipse. Its features were
clunky and slow. I felt the same about every other IDE I tried.
The modern Eclipse is responsive enough that it finally feels like
it's helping my productivity, not hindering it. Mostly.

More wild off-topicking, but this thread does seem to foster it ...
Just how much do we think the (I)DE or typing-speed affects
productivity? I know the former at least is task-dependent (if you're
given a huge amount of legacy code the needs every method and class
renamed, then Eclipsers will romp all over Notepadders), but in
general, can it affect much?
I'd guess not. I'd guess any difference attributable to a particular
(I)DE is so small that it sinks below measurable tolerances into the
noise of the (let's face it) astrologically inaccurate project planning
within which we work.
Well, I suppose there are some minimal basics. If you're given a new
(I)DE, and you never learn how to delete, then you're in for some tough
deadlines; but on the whole, I'd say productivity is far more weighted
by requirements-clarity, and programmer and tester experience.
That's probably why, "Use whatever (I)DE you're comfortable with,"
radiates such incontrovertable common sense: it gets you above the
basics; you can delete, save, compile, run.
There. DSCR. I've said it.

Are you using (or rather, avoiding) those modern "mice" that actually look more
like pregant rats ? Big bulky things that /force/ you to rest your palm on the
beast's spine ? If so -- and if you are like me -- that might be the problem.
With the old-style (shaped like a bar of soap) mice, I can guide the thing with
my fingers; in particular, making precise movements just by flexing my fingers.
With the new kind, that is impossible, so I have to make fine movements with my
wrist/arm, and that becomes killingly painful very quickly. The "rats" are
supposed to be more ergonomic, but not for me they aren't...

I'd say that a good (or bad) IDE is a lot more than just an editor, and that
it's the other things that significantly affect productivity. If your speed of
typing (with or without help from "Intellisense", etc[*]) is such that it is a
significant bottleneck then I would say that one of the following apply:
a) You are a /very/ slow typist (serious physical disability,
such as having no hands).
b) You are a /very/ fast thinking -- much, much, faster
than anyone I've ever met.
c) You are wasting your time doing writing repetitive code which
can be and should be automated (or otherwise changed to
remove the repetition).
d) You are a very bad programmer, who programs without
thinking even though thinking is required.
BTW, one place where I do think that fast typing (and good editing features)
make a real difference is that it becomes easier to document code
appropriately.

Maybe in the long term, in that it's may be encouraging memory lost:
I was in the middle of some Java method, and I had type
"someMethodCall( " and then paused, because I knew I wanted to put the local
variable I had declare some moments earlier there, but I couldn't remember
the name of the variable. Well, Eclipse, being what it is, looked up the
method definitions for "someMethodCall" and then found the arguments that
all of its overloaded variants expected. It then looked at all variables
that were visible from the location in the code I was located (local
variables, publicly visible variables, fields from parents, etc.) it then
looked at the type of all these variables, and climb their inheritance tree,
cross-referencing that with the overloaded variants, and seeing which
variables could actually be legal given the type-checking rules.
It then displayed a pop up with my local variable, essentially asking me
"Is this what you're looking for?"
All of this before I had time to send the signals to the muscles that
control my eyes to scroll up and read the variable declaration a few lines
above.
So I find auto-completion helpful, but it concerns me that I can't
remember things that I looked at only a few moments ago.

Oh, I dunno. There's a hard limit to how many things a given person
can keep in his/her "stack" at a time. You probably were juggling
enough other data that you just didn't have room for that piece.

- How know if a method is part of an interface?I have a class named MyClass implementing an interface named MyInterface.
I have also an instance of java.lang.reflect.Method describing a method
of MyClass (is the parameter of the invoke method in an
java.lang.reflect.InvocationHandler).
I need to know if Method is part of MyInterface or not.
Is there a way other than checking the method name and parameters type?

- Formatting JTextFieldsHi all!
I had this some time ago, but I didn't have the time. What is the best
way to accomplish allowing only certain characters to be entered in a
text field?
I remember having read about something subclassing Document, the text
field model, but it seems a little complicated to me.
I need a textfield where only letters can be entered, possibly a-z and
one field, where only digits are allowed.
Can anyone tell me how to do this, probably providing some short code
snippet?
Thanks for your help!

- Sorting a row of letters, using a blank space, with some added rulesI will have a line consisting of the letters A-E in a random order and
a blank space at the end. So that gives me positions 1-6. Now I want
them sorted to give me the order "ABCDE ", and the sorting would be to
put a letter into the empty space, and sort them that way. That would
be easy enough to code if it wasn't for some necessary rules.
It will not be possible to swap from any position to any position,
which possible moves there are, has to be hardcoded in, like for
example a small array, but since there are maximum 15 possible moves,
that should not be a problem.
For example I could have this starting line-up "BCEAD ". And you could
only move between positions 1 and 2, 1 and 4, 1 and 6, 2 and 3, 2 and
5, 3 and 4, 3 and 6, 4 and 5, 5 and 6.
So since my goal is to minimize the number of moves, in this case the
algorithm would produce the following moves, which is the shortest
solution.
"BCEAD "
"BC ADE"
"B CADE"
" BCADE"
"ABC DE"
"ABCD E"
"ABCDE "
I hope I've made my point clear enough. What I can't figure out is the
algorithm for this, which I hope some of you can help me with. I don't
expect finished Java code, properly explained pseudo code will do :)

- Fastest way to pass messages?Our app needs to have a central computer send a message to several other
computers, and then gather a response from each. This has got to happen
hundreds of times per second (not necessarily synchronously). Each
message is just an array of bytes, usually less than 100 bytes on the
way out and less than 8K on the way back.
What's the fastest, most efficient way to do it? RMI? Jini? JMS? REST?
Raw sockets?
I expect that some would say raw sockets, but my guess is that one or
more of the others might be nearly as fast and have other advantages as
well. Any advice is appreciated.

Dear port maintainer,
The following port has an incomplete pkg-plist, or other errors in the
files installed by the port. This may mean that the package is
incomplete or non-functional; at the very least, your port does not
leave the filesystem in the same state it was before the port was
installed. Can you please investigate?
Thanks,
Kris "Ports Janitor" Kennaway

- Applet and new window connection problem.Hi All.
During recent development I encountered a following problem:
My app uses 2 windows - in one - there's an applet that displays some
data structure (loaded from xml file with JTree representation). User
can browse through the hierarchy and than can click on the desired
node. When he/she does it - applet takes some doing and produces a xml
data that should be used by servlet invoked in the second window.
Generally I'm using showDocument(url, target) method to achieve that.
Problem is that with this approach I can ony pass short strings - as
in GET request. What happens is that my xml data can be quite big and
I really need to send them to servlet and display in the
applet-adjacent frame. I was thinking of some workarounds to this but
everything seems to be either not working either to complicated and
difficult to maintain.
Should you have any thougths, I would greatly appreciate.
TK.

- Jtable header clickable?HI!
I've been trying to find information on how to make the header of a
JTable clickable. I.e I want my users to be able to click the header
and the program do something smart (possibly sorting data, or
whatever)
I only seem to find references to dead-links when I search on deja,
and amazingly google did not seem to help much. Can anyone point me
the general direction on how to do this?
regards
Daniel

1966 at the /latest/ at Brown -- but that's in the University world.
In the business world, in the late 60s, programmers still had offices
(perhaps two to an office), and were indistinguishable from other
management-class workers, apart from, perhaps, a greater tendency to
work in shirtsleeves, with the jacket hung up or draped over a chair.
And some of them were women -- typically 30-40, married, with children.

- Sort objects in a vectorHello
I want to sort objects (implemented Comparable) in a vector. My method is to
use convertTo array function in Vector class then sort this array by using
Array.sort function. then I copy all items in this array into the old vector
(by removing all items in this vector and then uses function "add" function
in Vector class). Do you have any idea about this method..
Thanks

- Security for beans in web applicationHi,
I have POJOs acting as API to the application. How can I implement
authorization? I tried
Subject s = Subject.getSubject(AccessController.getContext());
Set<Principal> ps = s.getPrincipals();
// now i can authorize based on name or whatever
but i get a subject only if the method was called with doAs. But it
seems to me that if this will be my requirement, then just anybody will
call the methods with doAs, passing whatever principal they want.
In short, I'm a newbie in this. I tried to read some material, but i
confess this is very confusing to me.
So how do i get the username to authorize in a secure way?
Thank you,
Ittay

- method always visible by other classThen I have a class called MyDBConn.java, inside this class there's a
method called GetResultFromPazienti():
MyDBConn.java:
==================================
package cc;
import java.sql.*;
public class MyDBConn {
private Connection myConnection;
private java.sql.Statement stmt;
// ...
public ResultSet getResultFromPazienti2(String query) {
ResultSet rs=null;
try{
rs=stmt.executeQuery(query);
}
catch(Exception e){
alerts.showErr(e.getMessage());
}
return rs;
}
// ...
==================================
After this, I have a class called Paziente.java, from this class I
would call method: getResultFromPazienti2(), class is something like
this:
File: Paziente.java
==================================
package cc;
import java.sql.*;
public class Paziente extends javax.swing.JFrame {
private MyDBConn mdbc;
private java.sql.Statement stmt;
// ...
// ...
private void formWindowOpened(java.awt.event.WindowEvent evt)
{
ResultSet rs=mdbc.getResultFromPazienti2("select ... from ...
where ...");
try {
rs.next();
// ...
txtNome.setText(rs.getString("NOME"));
// ...
} catch (SQLException ex) {
ex.printStackTrace();
}
}
}
==================================
At first moment seem that are not problems, infact there's no problem
in compile time, but when I execute project and method
formWindowOpened() is started an "Exception in thread "AWT-
EventQueue-0" java.lang.NullPointerException", where are the
problems???
Thank you to all....

- Draw controls over custom paintsHi!
I'm trying to drawing under swing controls; actually i draw over all
japplet canvas with repaint method.
public void update (Graphics g)
{
g.fillRect(0,0,300,300);
}
If i declare a simple JTextField with this code:
JTextField field1;
[...]
panel = new JPanel();
field1 = new JTextField( 10 );
panel.add( field1 );
getContentPane().add( "Center", panel );
The textfield is created under the filled rectangle (so i can't see
it!); there's a way to draw the controls on top of the paint methods??
Thanks in advance!

- Java soluton for outputting English?Hi, I've generated a program that outputs a series of nodes eg, {A, F, L,
Z). This corresponds to the recommended route along a certain path. i.e.
starting at A go to F then L and arrived at destination Z. I want this to be
generated into English. for eg, I can deleiver to a user a message that
says.........
When at A turn letf for F
Then keep straight for L
fianlly turn left for Z
So there will be a fixed amout of Engkliosh instructions
1- turn left:
2- turn right:
3- go staright:
So basically I need to output a set of directions. In a database I have
stored information about roads and the different nodes on each road, my
problem seems to be deciding how each node and road are related to each
other, in order to instruct for eg' turn left'. To be honest I've racked my
brains trying to come up with a solution but I'm stuck. Can anyone recommend
any ideas?
If you like I can provide more information.
