- Drawing on TabsHi all - I have an application where my main frame has a tabbed interface,
and each tab has a JPanel.
I would like to draw a line graph on the second tab (the first tab is where
data is entered) and a bar graph on the second tab.
The problem I have is how to draw on the second or 3rd tabs.
I googled and one solution was to subclass the JPanel and then override the
paintComponent() method. I tried but it doesn't seem to work. I am probably
just doing it wrong.
How would I go about defining/extending the JPanel class? or is there some
other container that would serve this purpose better?
Any help is appreciated.

- AGLOCO- this worries GoogleHi,
AGLOCO- this worries Google
Bill Gates thinks Google should be worried!
-------------------------------------------
You must have heard by now about Agloco and how many people think it
is going to be bigger than Google... Now Bill Gates is on record
saying they have a great business model and that Google should be
worried.
Google search result produce - 1,400,000 web pages for Agloco.
Google makes billions of $$$ and keeps it all for itself... Agloco
one
day is going to also make billions of $$$ except it will be completely
shared out to its members!
You make money with Agloco by using your computer as you would
normally!
Plus Agloco has a great referral pakage!
So start building your network!

It's all over the blogosphere and Bill Gates has been quoted as
saying he believes it "will be the next big thing to hit the
internet", so
what is Agloco and will they really pay you for surfing the net?
I too was sceptical when I heard about it but after spending a few
hours googling and reading about it, I have not only come round to the
idea but am now thinking it could really work and could really make
us (that's me and all of you who are reading this) some money.

I think you're clutching at straws here, so what if people using dotnet were

- j2ee request resource is not available hello1Hi all,
I have found a solution to a problem that I would like to share.
I am running WindowsXP and J2EE sdk 1.3.1.
I was trying to run the Hello1 servlet example from the J2EE examples
from sun. I found this error message: j2ee request resource is not
available
Then I solved this problem by opening the application in deploytool:
Filling in the following fields:
Hello1App: WebContext-> WAR File = Hello1WAR; ContextRoot = hello1
GreetingServlet -> aliases = /greeting
ResponseServlet -> aliases = /response
This solved the problem and it was running fine.
Hope it helps,

- Preventing URLConnection from buffering entire output streamIn my client application, I upload huge files via HTTP.
The URLConnection class seems to automatically buffer
the entire contents, then when the OutputStream associated with
the URLConnection is closed, it computes the length
and prepends a Content-Length header before actually sending
any bytes to the web server.
This results in an OutOfMemoryException when the file is huge.
My application uses Transfer-Encoding: chunked, but
that doesn't help when the entire stream gets buffered anyway.
Is there a way around this without writing my own URLConnection
clone based on Sockets? Calling flush() on the OutputStream
seems to have no effect.
I understand that a workaround would be to use the new features
of Java 1.5, but that's too new to expect end users to have.
Any help would be appreciated.
Thanks!

- Can't locate JavaxHi,
I am using DrJava, and I am writing a program that has the following
statement:
import javax.swing;
It gives me this error when compiled:
File: C:\Program Files\DrJava\CustomJFrame.java [line: 1]
Error: package javax does not exist
I did set my classpath variable to:
c:\j2sdk1.4.2\lib\tools.jar;C:\j2sdk1.4.2_01\src\javax
where C:\j2sdk1.4.2_01\src\javax is where javax is located.
What am I doing wrong?

- "no cmp field defined in cmp ejb"I'm so boring I know... this is my problem...
I wrote the following entity bean, it rappresents something like this:
primary key id (managed by the container)
foreign key formulation_product (cmp relationship field)
foreign key ingredient (cmp relationship field)
public abstract class FormulationComponentBean implements EntityBean {
/* Relationship field getters */
public abstract FormulationProduct getFormulationProduct();
public abstract Ingredient getIngredient();
/* Relationship field setters */
public abstract void setFormulationProduct(FormulationProduct product);
public abstract void setIngredient(Ingredient ingredient);
[...create methods and others ejb* methods...]
}
When I try to autogenerate database table with Sun Deploytool I get this
error message: "no cmp field defined in cmp ejb".
I really do not need any persistent field, but only relationship field...
should I insert a fake persisten field just to satisfy that silly utility?
Or I am wrong on something?
Thanks a lot for any help...

- Why do JARs made with JBuilder 2006 Enterprise not work outside IDE???Hi all,
I have written a program in JBuilder 2006 Enterprise (Win NT, JRE 1.5)
which works perfectly within the IDE.
However, when I use JBuilder to create a JAR of my project and then try
to run in from the command line it throws the run-time exception
below...
Exception in thread "main" java.lang.SecurityException: class
"Com.package.MyPackage.MyExcpetion"'s signer information does not match
signer information of other classes in the same package
I have used JARs before but never come across this sort of error, maybe
worth adding that the program uses JavaMail to send emails.
More confusing, why does it work in JBuilder, but not outside?!?
Any help would be greatly appreciated, i am stumped!

- my JEditorPane.read() method is never referenced, why?[code]
public class SimpleHTMLRenderableEditorPane extends JEditorPane {
// borrowed from http://www.java2s.com/Code/Java/Swing-JFC/JEditorPaneandtheSwingHTMLPackage9.htm
protected String getNewCharSet(ChangedCharSetException e) {
String spec = e.getCharSetSpec();
if (e.keyEqualsCharSet()) {
// The event contains the new CharSet
return spec;
}
// The event contains the content type
// plus ";" plus qualifiers which may
// contain a "charset" directive. First
// remove the content type.
int index = spec.indexOf(";");
if (index != -1) {
spec = spec.substring(index + 1);
}
// Force the string to lower case
spec = spec.toLowerCase();
StringTokenizer st = new StringTokenizer(spec, " \t=", true);
boolean foundCharSet = false;
boolean foundEquals = false;
while (st.hasMoreTokens()) {
String token = st.nextToken();

String charSet = getNewCharSet(e);
System.out.println("charSet = " + charSet);
try {

super.read(reader, desc);
} catch (ChangedCharSetException ee) {
System.out.println("huh?");
} catch (IOException ee) {}
} catch (IOException e2) {}
}
}
[/code]
Per reference in http://kickjava.com/348.htm I am having to overwrite
JEditorPane.read() with my own method, I still get
ChangedCharSetException thrown when it should have been captured and
you should have at least seen something in output, yet you see noting
whatsoever except the ChangedCharSetException when you do this line:
[code]
// browser IS OF TYPE
SimpleHTMLRenderableEditorPane
browser.read(
new BufferedReader(new
StringReader(browser.cleanHTML(getURL()))),
browser.getDocument()
); // SimpleHTMLRenderableEditorPane HAS
METHOD cleanHTML(URL url) WHICH NEVER THROWS ChangedCharSetException
[/code]
Why is it that my method appears to never be referenced and the
default read() method in JEditorPane is referenced instead? Ideas?
Thanks
Phil

- Problem was javax.comm.ParallelPort 's getOutputStream() -ed objects write() method. HERE goes ANSWERTo all, who tryed to send tada to Parallel port using javax.comm api.
I had the same problem at home when I wrote program.
Then I went to my working place and tested my program, - the problem
remained - program hanged forever after sending bytes to parallel port.
I had tryed almost everything at home, so the way could be only one -
PRINTER and SO THAT WAS ENDEED!!!
I turned printer on and bytes went away :) program worked fine!
So, as we could see Windows platforms (and maybe others too) block all
outgoing signals to the ports from where OS does not get or receive the
signal that means the port is alive (=something is connected to that
port).
That was one more good lesson for me.
If this helped somebody, let me know.

- [?] Struts looses authenticate informations ?Hi,
I'm trying to make my first struts application and I'm fighting with
authentication and roles.
I've only one jsp page (index.jsp) that prints authentication type ("BASIC")
and user roles.
<%
authentication+="Authentication " + request.getAuthType();
if (request.isUserInRole("ADMIN")) { role += "ADMIN; " ; }
if (request.isUserInRole("USER")) { role += "USER; " ; }
%>
<br>----------------------------------------------------
<br><%= authentication %>
<br><%= "ROLES : " + role %>
<br>----------------------------------------------------
<br>
Then there's an empty form with a "submit" button.
<html:form action="/index">
<html:submit value="SUBMIT" />
</html:form>
the execute method in action is the following :
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {
String forward = "index";
return mapping.findForward(forward);
}
When I enter my application the first time it shows exactly authentication
BASIC and ROLES : ADMIN
but when I press "submit" it shows "authentication NULL" and "ROLES : "
I'm using tomcat 4.1.18 (I also tried .24 and .27 !) and struts 1.1
WHERE' S THE ERROR ??

- deploying multiple instances of same application (.war file) on tomcat 5.5We have a web application running on tomcat 5.5 that works fine when

- Write PNG from MemoryImageSourceI have an application which dynamically generates images using
MemoryImageSource to produce a java.awt.Image object. I'd like to be
able to write these images out as pngs.
I've found the javax.imageio class which will write out pngs, but only
from a BufferedImage and not from a basic Image. I've not been able to
find a way to create a BufferedImage from an Image.
Can anyone suggest how I can write out these images?
Cheers

- Java is a third class language.Hi Mark Thornton,
Re: Windows' GDI for easily writing to any raster device
using essentially the same code,
regardless of the printer or the screen.
You asserted,
" Not only does it work well ( in Java )
it also supports some features ( e.g. anti-aliasing )
which may not be available on the OS. "
Even if that were true ( and I highly doubt it ),
Java still couldn't do it with out the OS.
Java Overlays an OS, it doesn't replace it.
Java is a third class language.
No one would use it if they didn't have other options.

- Jedit: Error about MouseWheelListenerI installed the same Jedit archive on Windows and on HP-UX (with
JavaVM-1.3). On
Windows, it runs fine. On Unix, I get the following error message on
startup:
java.lang.NoClassDefFoundError: java/awt/event/MouseWheelListener
Could it be that something is missing in my CLASSPATH? Where is the
MouseWheelListener
supposed to be? I thought this class was added in 1.4, but note that
the
installation notes for JEdit say that it can run under Unix with Java
1.3.

- ResourceBundle with Database BackendHi all,
We're busy creating a web application that needs different localization.
ResourceBundles would probably be the best thing to use for this. However,
we would like to use a database as the backend for the ResourceBundle.
This would make changing and adding translated strings much easier. We
would like our client to be able to do this himself, using a front end we
will write.
From what I understand of ResourceBundles, we would have to create a
ResourceBundle class for each translation. We'd like to create just one
subclass of ResourceBundle however, which handles all translations. Is
this possible? I can't find any examples of how this should work..
thanks for thinking along, please tell me if my question isn't completely
clear or something like that,
Ilja Booij
