In addition to Kristofer's comment..  Why would you need help with an 
assignment like that?  It's the kind of thing anyone should be able to 
do drunk, and even understand what they did when they sober up.

Why not outsource it to another country, grab a phone book. You can
probably get all your course work done there not just java.

Now all that's missing is for some Indian to pipe up and quote 10,000 USD

Actually, I'd be willing to do this assignment for US$5,000.  For an extra
grand, I would even explain on how it works.

If you revisit the API docs, you'll find that the mere act of 
instantiating many Swing components throws the HeadlessException if 
there's no graphics environment (see the JFrame constructors for an 
example).  So you've got to go back into the code and suppress the 
instantiation of those items if you want to be able to run in this 
environment.

Alternatively, as the message indicates, you may be able to set the 
DISPLAY variable.  But that may not be reliable -- can't say, as I 
haven't tried this myself.

I have not used X11 in a while, but the DISPLAY environment variable
is used to determine the location of the screen etc. for the server
which is normally your terminal but you can assign it to another
terminal if you want to. If you assign it to /dev/null it may not
work, but it is worth a try.

If you're running ssh from an X session and your server's ssh daemon is
configured to permit X11 forwarding to the local display then pass the -X
flag to ssh (or put the corresponding option into your ssh config file).

E.g. 

$ ssh -X [EMAIL PROTECTED] java -cp ...

The server config option you need is :

X11Forwarding yes

If it's not enabled then the admin might be prepared to enable it for you
(especially if you're the admin ;-) ), but do first read the ssh manpage
for a warning about using X11 forwarding.

With JSP, always focus on the output.  Most JSPs, including yours, 
output HTML code.  Determine how to code the visual effects you want in 
HTML, then make your JSP produce that output.  The HTML details are 
off-topic for this newsgroup, but your main options are to use Cascading 
Style Sheets (preferred) or to insert appropriate styling markup (e.g. 
<font> elements, which you seem to already be doing).

I don't see how you expect it to work at all, then.  When the JSP is 
processing a request it has only the information available from the 
request, session, and application.  The JSP cannot presciently determine 
how the client might react to the response, and it cannot do anything to 
change the response once it is sent.

However, if you can create a table with the correct number of columns in 
the first place then you necessarily know some number of columns that 
the client *already* requested.  Either you're missing something here or 
I am.

So what's the problem?

If you need help with the Javascript then this is the wrong group. 
Javascript is a completely separate language from Java, with only 
superficial similarities.

If you need help generating a random number, then look into 
java.util.Random and / or Math.random().

If you need help creating an input field then see my above comments 
about HTML.

That is truly abominable JSP code.  Sorry, but it is.  See all those 
out.print() and out.println() invocations?  One of the original goals of 
JSP was to not have to write servlet code that looks like that.  Why are 
you even bothering with JSP (instead of a pure servlet) if you're going 
to write it like that?  Also, most interested people agree that JSP 
authors ought to focus on minimizing the use of scriptlets in their JSPs 
[some even argue that scriptlets should be avoided altogether], but your 
JSP is almost all one big scriptlet.  Furthermore, unless you've 
truncated it, your JSP doesn't even produce a valid HTML document.  And 
that's before we even get to not putting your HTML attribute values in 
quotes, not using consistent coding conventions in your scriptlet code, 
yada yada yada.

Count me among those who eschew scriptlets. Either use existing tag
libraries or roll your own. It's not that difficult and makes the JSP
so much easier to read. It's also easier on your graphic artists when
you explain that they just need to use a particular tag to obtain
desired functionality. This will be familiar since HTML is merely tag
markup. Embedded Java code just makes their heads spin...  ;-)

Did you handle exceptions correctly in server ?

And have you tried without the flush() ?

While I don't have the time (if you don't have the money) to address
your problem directly, I can suggest an article I've written:

The best way is to assume that you can write until you get a return 
value of zero from the write call. When this happens on a channel you 
should register the channel for OP_WRITE. Whenever you succeed in 
writing all the data you asked to write, you should deregister for OP_WRITE.

From: "MikL" <[EMAIL PROTECTED]> 

Hi all,

I have a Swing UI containing JTextFields.  When the user moves the focus
into a JTextField using the keyboard (eg. by pressing TAB), I want to use
selectAll() so that the user can then overwrite the field contents without
messing with the mouse or having to type multiple backspaces or other
keyboard gymnastics.  However, I _don't_ want to selectAll() if focus was
moved to the field using the mouse.

Currently I'm looking at monitoring the sequence of FocusListener and
MouseListener events to determine whether the user used the keyboard or
mouse to move focus, but it seems unelegant and relies on eg. mousePressed()
running after requestFocus() and before focusGained().  Is there a better
way to detect how the focus was moved?

Regards,
MikL

Your problems begin right here.  You should not be using a D'n'D
editor* to design your Java at this stage, since you have little 
idea of what you are doing, like..

I can take a rough guess, but you need to know, and need 
to write some Java without that.

org.netbeans.lib.awtextra.AbsoluteLayout is the class, and you specifically 
have to put it in your classpath otherwise your compile will fail.

While that may technically be the case, I feel the OP
would be better served by ..

a) Learning the Sun layouts.
<http://java.sun.com/docs/books/tutorial/uiswing/layout/using.html>

b) Following the advice in the first (c.l.j.help) and second 
(set aside Netbeans for the moment) of the links you trimmed.

That looks like a package problem. Is PrimerForm in the primeraapp package
by any chance?

You should run java from the base directory of the package structure, not
from within a sub-package. You need to move up out of the primeraapp
directory and then run:

java primeraapp.PrimerForm

The ComponentOrientation class encapsulates the language-sensitive
orientation that is to be used to order the elements of a component or of
text. It is used to reflect the differences in this ordering between Western
alphabets, Middle Eastern (such as Hebrew), and Far Eastern (such as
Japanese).

Fundamentally, this governs items (such as characters) which are laid out in
lines, with the lines then laid out in a block. This also applies to items
in a widget: for example, in a check box where the box is positioned
relative to the text.

There are four different orientations used in modern languages as in the
following table.


 LT          RT          TL          TR
 A B C       C B A       A D G       G D A
 D E F       F E D       B E H       H E B
 G H I       I H G       C F I       I F C

(In the header, the two-letter abbreviation represents the item direction in
the first letter, and the line direction in the second. For example, LT
means "items left-to-right, lines top-to-bottom", BL means "items
bottom-to-top, lines bottom-to-top", and so on.)
The orientations are:

  a.. LT - Western Europe (optional for Japanese, Chinese, Korean)
  b.. RT - Middle East (Arabic, Hebrew)
  c.. TR - Japanese, Chinese, Korean
  d.. TL - Mongolian
Components whose view and controller code depends on orientation should use
the isLeftToRight() and isHorizontal() methods to determine their behavior.
They should not include switch-like code that keys off of the constants,
such as:

Hello,
I added mail.jar and activation.jar into CLASSPATH. When compiling a java
file, e.g msgsend.java, successful, and generate msgsend.class. But when
excecuting msgsend, failed. It shows:
Exception in thread "main" java.lang.NoClassDefFoundError:
javax/mail/Message
I do as following:
in java compile file, add mail.jar and activation.jar into classpath:
@echo off
set
CLASSPATH=d:\;D:\Java\Javamail\javamail-1.3.2\mail.jar;D:\Java\Javamail\jaf-1.0.2\activation.jar
set PATH=%PATH%;C:\j2sdk1.4.1_02\bin
javac %1
pause

Can anybody tell me how to set CLASSPATH? Thank you.

Hello, there!

I hope, someone can help me with my problem:

We have developed a CRM system (Apache+Tomcat+Struts+M$-SQL) which
does provide reports. These reports are integrated as SQL-Statements
in JSP pages and executed there via a Taglib. The result is always
a styled HTML table.

But now we want to expand this service by providing an export of these
tables additionally as Excel or PDF (in the same style). Therefor we
have searched for a solution which already provides such a feature.

Apache's Cocoon has cought our attention there.

Our question: Is there a good tutorial out there how to integrate
Cocoon in an already fully developed environment like a CRM system?
I googled the net but so far I have not found a satisfying document.

Maybe someone knows the place to look? ;-)

Thanks in advance for your help,
Thomas
