Why my JFileChooser showed as a FileDialog?

Hello!
I'm doing a project to update some existing codes. I made a change to use JFileChooser to replace FileDialog since I can customize JFileChooser. However, after I have replaced FileDialog with JFileChooser in code, it still show as FileDialog when I run it. I'm very sure that I'm using the changed codes since I can see other changes I made in the file. The runtime environment could be a little strange, I heard it may not support Java.Swing. However, I used some other Swing components they all come out fine. It seems that JFileChooser is not supported so it fails back to FileDialog automatically, does anyone know anything about this?
Thank you very much.

We can't really diagnose your problem just with what you posted.

If it displays a JFileChooser, you'll know there's a bug in your code. If it displays a native file chooser like AWT does, then you may be correct.

Why PSA data show red status when opened but green on PSA page?

Run RSA1 -> click PSA to open PSA page, locate one infosource and find the PSA under it, find the status column shows it's green, but when opening it, find the 1st column shows red for each row. How does the inconsitance occur?
BTW, if we open the infopackage monitor for the above one, find a weird thing is that each request get two consecutive processes running with a circle of red ball and green ball in the left frame. Double click one of them, in the right frame and click the monitor Status tab, the msg window is as following (in between two dashed lines below):
Incorrect data records - error requests (total status GREEN)
Diagnosis
Data records were recognized as incorrect.
System response
The valid records were updated in the data target and can be used in reporting.
The incorrect records were not written to the data target, but were posted retractively under a new request number in the PSA.
Procedure
Check the data in the error requests, correct the errors, and post the error requests.
Sounds like the data failed to uploaded to data target due to error in PSA, but why the status show green in somewhere? And if clicking the Details tab, all show green! Weird!
Thanks

Hi Kevin,
In your InfoPackage Update tab, click the Error Handling button. It seems that the Valid records update, request green option is chosen. This is why you see the green request and some error records.
This means that the corect reocrds were loaded and are available for reporting, but the incorrect ones were left behind. This is used to check the erro records separatelt so that they do not disrupt the entire data load.
Hope this helps...

Why does firefox show up as a plugin on volume mixer?

Why does firefox show up as a plugin on volume mixer? After updating a flash plugin into firefox (when it had requested me to update it), it no longer shows up as firefox in volume mixer. It now shows up as some plugin icon. I really don't understand this, and wish it to be the firefox icon again. What is going on and what happened? It names itself "Plugin Container For Firefox" What does that mean? It has been this way ever since, and nothing I have done has fixed this. Restarting, refreshing, reinstalling, clearing cache, etc. Can anyone think of something please? :(
== This happened ==

I have this, but my volume on firefox doesnt work at all

Just installed mountain Lion. Viewing a pdf sent to me using preview and some colors are appearing BLACK, however when I view the same PDF in Acrobat they are perfect and what they are suppose to be. WHY would PREVIEW showing a different color?

Just installed mountain Lion. Viewing a pdf sent to me using preview and some colors are appearing BLACK, however when I view the same PDF in Acrobat they are perfect and what they are suppose to be. WHY would PREVIEW showing a different color?

Here's what I've found on the issue:
Pantone color definitions have changed (coinciding with CS6) — they are now "Pantone+" (I think that's what they're called). The "+" apparently means they're now LAB colors. Lab colors are not properly displayed in Preview (or in Finder previews) — they display as black (as far as I can tell, in all circumstances). I'm sure it's a tad more complicated than that, but that's the gist.
Now the bad news — nobody seems to know anything about a fix or workaround (unless you convert your PDFs to process — this might be a fix for sending to clients). It causes issues for me in AI files — being able to view them in the finder (with previews) is a HUGE time saver for my workflow... when they're all black, not so much.
In my chat with a director of product dev at Adobe, they placed the responsibility to fix on Apple (assuming Apple wants to support Pantone color definitions in their OS).

I have an iPod touch 4th gen. why does it show the wrong album art only on my ipod and not on itunes? Is there any way I can fix it?

I have an ipod touch 4th gen. why does it show the wrong album artwork on my ipod and it's fine on itunes. why is that and is there any way to fix it? please help!

I think it can't find the right or any artwork and ends up putting junk in there.
And can happen with artist and other tags.
probably fine with commercial media but otherwise....? I think you have to manaully go in and edit
I also don't like how it handles and stores non-Apple iTunes store content.

Why wont it show me my order status on the iPhone 6, 16GB, Gold?

Why wont it show me my order status on the iPhone 6, 16GB, Gold?
I ordered it on 9/27/14, and I got the email that said to check the order status, but when I go to the page it said nothing.

I was in a similar situation. The phone I ordered was in stock, with supposedly no shipping delay. I ordered on 9/27, but it actually took four extra business days for Verizon to ship my order.
I called twice and both times the reps couldn't help be determine the status.
My assumption is Verizon fulfillment is swamped with orders. They SHOULD have a way of determining real status but they don't.
I would suggest waiting a few more days, then call the Internet Order group at 800-922-0204 and start complaining.

why plan table showing one record when i have no record in table a.

This is because you did not analyze the table, and if it was analyzed, it maps a zero to a one. Please not that my test is not in 10g but on 9iR2, where non analyzed tables have null values in their estimated cardinalities.
