HELP NEEDED: FIRST SWING AT ECOMMERCE
Im doing a site for a catering company and I need to get my
hands on some tools that would be useful for building the ecommerce
part. I havnt really done that much with ecommerce and the company
wants nothing to do with paypal. They want orders to be sent via
email to both the company and the customer as well (basically as a
confirmation) . Any help getting pointed in the right direction
would be amazing!
thanks
I second the nomination for cartweaver
In addition to ease of customization and good company
support,
there is a fairly active newgroup-based user community as
well.

HI friends,
I have a GUI with 4 paem nels .On one panel ..i have a menu item
called "Create" when i click it an oval will be drawn on a canvas.
And i have the Buttons on the other panel .
I need to drag these buttons and drop them into the ovals.
Can any one help me wih the drag and drop functionality using swing.
Thanks in avanceDid you know there is a Swing forum where you can post Swing questions?
http://forum.java.sun.com/forum.jspa?forumID=57
If you do repost this there, please put a link in this thread to direct interested people to the new post.
I don't know anything about how to do drag-and-drop in Swing, so I can't help you directly with that. Good luck! -
I have written a small hellow world code in swing....
*import javax.swing.JFrame;*
*import javax.swing.JLabel;*
*public class HelloWorldSwing {*
*public static void main(String[] args) {*
*JFrame frame = new JFrame("HelloWorldSwing");*
*final JLabel label = new JLabel("Hello World");*
*frame.getContentPane().add(label);*
*frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);*
*frame.pack();*
*frame.setVisible(true);*
I've compiled this in a remote server, with the help of this site....
http://www.innovation.ch/java/java_compile.html
I have only JRE1.6.0_03 installed in my machine.....
when I am trying to execute the program by.....
F:>java HelloWorldSwing
it is saying....
Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorldSwing
Then I tried to run it othe way by html file....
*<html>*
*<applet class="HelloWorldSwing.class" height=200 width=200>*
*</html>*
can any one suggest....what to do to get it running?um.... how about get the JDK?
Also, please don't try to use a non-applet program as if it were an applet. It won't work.
Also, please go through the Sun Java tutorials, especially the first ones about getting started.

hi,
Hi, .
I have created a Jmenu called " Menu System Test window " and it contains toplevel menu item "File" and File Menu contains subitems "Product Evaluation" and "Exit".
When i click File->Product Evaluation it displays a new Frame named "ProductEvaluationMeasurementTool" with some check boxes ,radiobuttons, buttons . Everything is ok with my code.
My question is now i want to convert my application into applet ( at present it is written using swing and AWT).
Can anyone tell me is it possible to converty my code into applet so that i can place it in a web page
i am sending my code..

I am trying to run java program on Linux machine which doesn't have GUI support. Due to that following exception is throwing,
java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
at java.awt.GraphicsEnvironment.checkHeadless(Unknown Source)

at ismschart.jChartTbl.createIsmsChart(jChartTbl.java:197)
at ismschart.jChartTbl.main(jChartTbl.java:98)
Can any one tell me, How to overcome this?
Is there any tool which provides UI support for Linux?

Help needed in understanding GridBagLayout situation
I have a JPanel with a JInternalFrame and a few JPanels inside of it. The JPanel is using GridBagLayout.
When a user moves the JInternalFrame inside of the panel what is happening exactly? How is it moving the frame with relation to the Layout? It doesn't appear to be bound by the Layout. When the user drags the frame to a new location what methods are being invoked?Having looked at the JXMapViewer which extedns XJPanel and XJPanel extends JPanel.
so if you want to get notified you need to add ComponentListener to the instance of JXMapViewer to get notificed when the following happens
The below is a copy from java tutorial for internalframe and I have added the MyComponentListener just to give you some ideas.

Help needed refactoring my AutofillTextField
Hello everyone,
Implementing an autofill feature for JTextField raised several design issues, and I would like some help.
First, source code, demo and a diagram can be found on my JRoller entry: http://www.jroller.com/page/handcream?entry=refactoring_challenge_autocomplete_jtextfield
Most difficulties are due to the mix of input and output. I imply what was auto-filled by selecting that part of the text. This affects the input on the other end.
An auto-filled selection doesn't behave like a normal one. Backspace will delete both the selection and an extra character. After that it immediately searches for a match, and auto-fills if necessary.
Adding characters in the middle and getting a match, advances the caret as normal, but also auto-selects the text from that point. So the output "talks" to the input to get the normal caret position.
To intercept text changes in JTextField I override PlainDocument, but other objects need access to the original, super-class methods. For this they use an inner class with methods wrapping the super-class methods.
I wonder if this overriding forces some dirty code, or maybe I can always abstract it away. Maybe I must intercept text changes some other way to make everything cleaner, like removing all keyListeners and add my own. But I doubt that.
My guess is that i'm just unable yet to see the right abstractions, and maybe I didn't go far enough with seperation. Anyway, I need help :). I tried not to ask, but this is going on for too long.
Thanks,
Yonatan.

}I made the code very simple in the interest of discussion in this forum.
1) Now everything is in one class.
2) I extend DocumentFilter instead of Document, which already implements the acrobatics I tried earlier.
3) I Commented most parts of the code.
How would you refactor it? It can be as simple as splitting into more methods, but you can also introduce more objects, and maybe even use a GoF pattern.
Here is the code. Good luck :)

Actually I am adding items to my JComboBox dynamically. My problem is that if I add the items with the same name and then explicitly set them selected my first item with same name is always highlighted and selected even though I say to select the last item which I add. But when I pull down the comboBox my first item with the same name is selected and highlighted not the last one. Please run the program and see. How can I solve this problem help needed.

I want to select the last item I add even if there exists an item with same name.
Any help is greatly appreciated.
Thanks.never mind I got the answer.

Help needed to create Quik Time VR movies, step by step
Hello,
thank you for your attenction.
I need to create Quick time vr movies, and I need to know the exact sequance of steeps to do it, and if the starting point I use is correct.
1) I shooted a sequence of photos with my digital camera (for example: www.stebianchi.com/quicktimevrhelp/still-photo.jpg).
2) Then, with photoshop (CS4) I choose: Automate/photomerge and I select all them to joint them in a bigger 360° panoramic one (www.stebianchi.com/quicktimevrhelp/pan.jpg). If, untill here, all is correct, the first question: in photoshop Photomerge layout option, do I have to choose one voice "auto, perspective, cylindrical, spherical, etc..." rather than anoter one of these?
3) from here, I really need your help.
First of all: the great doubt:
My photos can not cover a spherical panorama, they're only a "ring" around a center (and not a spherical texture). To cover all the surface (or almost all, ok...) of my ambient, do I have to use a wider lens on my camera or there is a different solution (for ex a vertical photomerge?).
4) Done this, I think I shuold buy a software like Cubic converter, to set and export the QTVR movie. Right?
Thanks a lot guys,
all the best!
StefanoYou can call your local apple store(find one on the home page of apple.com) and they will give you instructions how to convert DVD to iPod. That is what they told me, but from what I heard, you may need more than Quicktime Pro. Just call and ask them, because if you make a manual of how to do it, it could help me a lot.
(I'm looking for a good DVD converter, already know some, beside the internet download ones)
