html code
<html>
<head>
<title>AppletMenuDemo</title>
</head>
<body>
<applet
code = "TabbedPaneFlags.class"
width = 450
height = 350
alt="You must have a JDK 1.2-enabled browser to view the applet">
</applet>

</html>

You should try the html converter so that the browsers are forced to invoke their plugin... or prompt the user to download one.
To turn an applet into an application is easy. You act like the browser. You make a frame, construct the applet, and put the applet in the frame, (They are components) ... Then just call the init() method. Then add a window listener to call the stop() method when the frame gets closed.
Application to an applet is a bit harder. You need to figure out what needs to be in the init method. Depending on what the application does you can also run into security issues.

Cannot convert Word to PDF - please help?

Hi I am running Windows XP, Office 2003 and Acrobat Writer 5.
I've had the same setup for five years and have always been able to covert Word documents to PDF like this:
File/print - then I select Acrobat PDF writer from the list of printers, and click "print to file" and it's done.
I've created thousands of PDFs in this way. I've also reformatted my hard drive and re-installed all the same programs again, and always been able to print to PDF.
Last week I again reformatted my hard drive, and re-installed all the same programs that I have always had. I have changed nothing, absolutely nothing about the setup of the computer.
However, NOW when I click file/print from Word, there is no longer Acrobat PDF writer listed!
And so I cannot convert to PDF.
Can anyone please tell me how to get Acrobat back into my list of "printers"?
Thanks

As I recall, Acrobat Distiller and Acrobat Writer are 2 different print drivers available with AA5. The Writer is not installed by default and is not recommended. It was almost not included with AA5 as I recall. It is no longer included with any distribution. The Acrobat Distiller printer (now renamed as the Adobe PDF printer) is the preferred method of printing with AA5. This latter process creates a PS file and then (using AcroTray running in the background) calls Distiller to complete the conversion from the PS file to the final PDF file. There are several options available under the list of settings. These can be set in the Acrobat Distiller printer properties and generally override the settings in Distiller. You can further make changes for the current printing in the printer properties menu of your current application.
Hope that helps explain what you have found. I still have AA5 running on XP. I also have a newer reader installed because of the limitations of reading some of the newer PDF files with AA5. I try to be careful with how I use Reader and AA5 as they can cause conflicts in what is used to open a PDF, and that is why this configuration is not recommended.

i did it my self and it didn't display components and
gave me a complain of java.io i used.please, someone
help me.thanks in advance.That didnt make any sense. If youre getting an error, post the complete error message, along with the relevant code.

Errors running converted application (from applet)

I've converted some codes (applet) into an application. When I run the application, I can see the GUI, but the application reports error as follows:
Exception occurred during event dispatching:

What I see is only the GUI less the animation that occurs when it was an applet. Could anyone offer me any suggestions or help? Thanks a lot.

Unable to deploy example 'banking' application on weblogic, please help...

Hi,
I have downloaded the example 'banking.zip' and have installed it.
I have followed all given steps in the tutorial, but I am unable to
see the login page.
I am also not able to see the ejb and web application descriptor file
from the admin console.
I have copied the banking directory to
'$WEBLOGIC\config\mydomain\applications'.
There are 3 directories under it
(1) ejb (containing meta-inf and examples directory. Meta-info
contains the descriptor .xml files)
(2) web (containing web-inf and html,jsp and image files. Web-inf
contains weblogic.xml and web.xml)
(3) Meta-Inf (containing the application.xml)
I get the 'Error 404--Not Found' error when I go to
http://localhost:8001/banking/login.html. (my server is running on
8001 port, i hope this doesn't matter)
When I try to edit the web application descriptor I get the following
error

Hi,
I was able to successfully deploy after installing
weblogic 6.1 SP2 (earlier I had SP1). Also, I had to make
changes in the BankAppServlet code since it tries to find the
bean with a different name than one specified in jndi-name.
- Thanks,
Sonali

Hi,
I have downloaded the example 'banking.zip' and have installed it.
I have followed all given steps in the tutorial, but I am unable to
see the login page.
I am also not able to see the ejb and web application descriptor file
from the admin console.
I have copied the banking directory to
'$WEBLOGIC\config\mydomain\applications'.
There are 3 directories under it
(1) ejb (containing meta-inf and examples directory. Meta-info
contains the descriptor .xml files)
(2) web (containing web-inf and html,jsp and image files. Web-inf
contains weblogic.xml and web.xml)
(3) Meta-Inf (containing the application.xml)
I get the 'Error 404--Not Found' error when I go to
http://localhost:8001/banking/login.html. (my server is running on
8001 port, i hope this doesn't matter)
When I try to edit the web application descriptor I get the following
error
java.lang.NullPointerException

Ipod says that files are being used by another application...please help!

My ipod lost all of my music but tells me that there is apparently still the same amount of memory used, i just can't access my music. To fix this, i'm trying to restore my ipod and just resync the music. However, every time i click restore i get the message "Itunes can not restore Ipod because it contains files in use by another application" even though there are no other applications running. I've ever tried restarting the computer to be sure that no applications are running. Please help!

I had the same issue with my new iPod 4gb nano. To be perfectly honest, I fixed it and I'm not exactly sure what part of the process actually did the job, so I'm going to attempt to explain it as best I can.
Basically I bought the nano to replace my 160gb classic aka paperweight. I'm currently deployed and the thought of traveling back to the US without a portable music player made me shudder. Within 4 days new nano click wheel decided to do the whole dying thing where I could click the buttons but not scroll through my music/change volume. I took the defunct iPod back to the BX and they exchanged it. I got home and discovered the "new" one they gave me was actually one that had been returned..because it popped up as "josh's ipod" when I plugged it in. So I'm on my third device and you can imagine when my computer informed me said device was corrupt and couldn't be read by my computer..I was pretty peeved. It took 7 or 8 tries to get the new nano update to install on my slow connection and when it finally did..I got the message that the files were in use by another application and couldn't be restored. I restarted the computer, made sure all other applications were shut down, checked my virus software. No dice. I ejected the ipod from my computer, plugged it back in and went into itunes preferences and clicked on "reset sync history". I think at this point it then treated the iPod as if it had never been plugged into my computer before. I then attempted the restore again, it did its thing and I now have a nice, new functioning iPod.

Problem to debug applet, please help...

i use windows.
there are 3 files under "c:\current" directory, they are
file 1. mem_appletviewer.bat - with content:
"e:\install\java\jdk1.3.1_05\bin\appletviewer" -J-Xdebug -J-Xrunjdwp:transport=dt_shmem,address=conn001122,server=y,suspend=y test.htm
file 2. mem_jdb.bat - with content:
"e:\install\java\jdk1.3.1_05\bin\jdb" -attach conn001122
file 3. test.htm - with applet tag:
<applet
code="Let0.class"
codebase="G:\Victor\Vc5060\Develop\JCity\files\RecentFile"
width=400 height=250 ></applet>
(Let0.class is a simplest class extends Applet)
please note, codebase is not "c:\current" directory
problems happend when i debug: (run mem_appletviewer.bat first then mem_jdb.bat)
a) if move Let0.class to "c:\current" directory, debug is fine but test.htm can not load Let0.class itself because of codebase tag.
b) if move Let0.class to codebase directory (G:\Victor\Vc5060\Develop\JCity\files\RecentFile), test.htm can load the class but appletviewer can not load the class (can not find Let0.class).
===========================================================
in my application, i need to put Let0.class in codebase directory.
Question:
1) how to set -classpath for appletviewer (as debug application class in java.exe )? is it possible?
2) codebase TAG in test.htm doesn't work for appletviewer, what is problem? how to fix it?
totally:
how to debug Let0.class if it is in codebase directory (not in "c:\current")?
thx

i fix it.

"Application Not Responding" please help!

Okay this problem has been occurring for about a month and I cannot handle life without iTunes:
Originally, my iTunes randomly stopped working and I would try to open the application, but it showed me a blank library with the spinning wheel.
I then tried to solve the problem by deleting unnecessary programs, restarting my computer, and uninstalling and reinstalling iTunes because the dock said that the application was not responding, so I would have to force quit.
Now, I get as far as the "iTunes Setup Assistant" by the time the color wheel starts spinning and the application stalls again.
I tried creating a new account and opening iTunes and that seemed to work fine, except a third of my library wasn't appearing and it's frustrating to have to keep logging in and out of accounts.
Also, whenever I plug my iPod into the computer and load Senuti, I can listen to songs off of that, but I can't add or modify songs on my iPod.
Please help me solve this problem!

You have a UAD-1e and you're getting a kernel panic from a conflict with the UA driver.
You should send this to Universal Audio tech support. This used to be an issue with sleep, but I believe they fixed that fairly recently, so I'm not sure why it's happening to you.
In the interim, also make sure for the moment that sleep mode on your computer is OFF, and that you are using the latest UA software.

Help with Illustrator Script! Batch convert files including subfolders - please help! :)

Hello,
I honestly have tried reading the other answers and researching to try to solve this problem. I'm sorry for my ignorance in this area. Please help!!!
I'm trying to make a script (for Illustrator CS2) that will batch convert several files to PNG files. The source folder has several subfolders and I need the script to go into the subfolders and convert those files as well. The destination directory should be an entirely separate folder but with the same hierarchy as the original source folder.
The script I have been using (that converts just as I need) is below. The only problem is it doesn't do the subfolders.
Any help would be so amazingly appreciated!

My iphoto icon has disappeared from my dock and applications folder. Please HELP

I tried clicking on the iphoto icon in the dock and nothing happened. I went looking for it in the applications folder and it wasn't there. I then moved the icon from the dock on to the desktop and it poof'd into thin air! GONE. What can I do? Please help! VERY upset.

reinstall iPhoto from the restore disks that came with your computer -
reinstall iPhoto - go to your receipts folder ("Your hard drive" ==> library ==> receipts) and remove any iPhoto receipts and reinstall from the restore disks that came with your computer - do a custom install of bundled software only
