JavaHelp with JavaWebStart: grey frame

Hello all,
I have my help in HTML pages on a Web server. The client is using JavaHelp to display these HTML pages.
It works fine, if I run my client through an IDE (like JBuilder). However, it does not work, if I run using JavaWebStart. I get a grey window frame (no TOC, no HTML pages displayed).
The code I am using to get an instance to JavaHelp is the following:
URL hsURL = new URL("http://myserver/myHelpSet.hs");
_hs = new HelpSet(null, hsURL);
hb = mhs.createHelpBroker();
Then later,
jMenuHelp.addActionListener(new CSH.DisplayHelpFromSource(_hb));
This seems to work fine. I do not get any exception. The helpset seems to be correctly located.
Any idea would be very welcome. Thank you. Marc.

I am using webstart as well, but I am delivering my help files in a jar file that gets downloaded to the client. The helpset file seems to be getting loaded fine, but I am getting a security error when trying to launch help from the application. This all works outside of Webstart delivery. Here is the error message:
"Parsing failed for null
Exception caught while parsing nulljava.security.AccessControlException: access denied (java.util.PropertyPermission user.home read)
java.lang.NullPointerException
     at javax.help.plaf.basic.BasicFavoritesNavigatorUI.reloadData(BasicFavoritesNavigatorUI.java:290)
     at javax.help.plaf.basic.BasicFavoritesNavigatorUI.installUI(BasicFavoritesNavigatorUI.java:228)
     at javax.swing.JComponent.setUI(Unknown Source)
     at ..."
Obviously a security issue, but since all of the help files are in a jar file, shouldn't this be legal? Maybe JavaHelp is just trying to read the files normally I guess.

Firefox upon opening an image in a new tab, centers the image from top and bottom and surrounds the image with a grey frame. Just started having the problem today, searched Google to no avail.

Firefox upon opening an image in a new tab, centers the image from top and bottom and surrounds the image with a grey frame. Just started having the problem today, searched Google to no avail.

Oh wow, looks like a new feature.
The "page" links in a stylesheet with the address "resource://gre/res/TopLevelImageDocument.css". If you remove that reference, then the image displays in the old style.
'''''Edit: Please skip the rest of this post and check out the next one.'''''
There might be a more elegant solution than that, but you could use a bookmarklet to strip out that link when you want to view the page in its old style. A bookmarklet is a snippet of JavaScript you save on the Bookmarks toolbar for quick access.
First, copy the following code to the clipboard (it's all one long line):
<br>javascript:var ssheet=document.querySelector('link[href="resource://gre/res/TopLevelImageDocument.css"]'); if(ssheet)ssheet.parentNode.removeChild(ssheet); void 0;
Next, if you are not displaying the Bookmarks Toolbar, use View > Toolbars > Bookmarks Toolbar to display it. (If you aren't using the classic Menu bar, press Alt+v to call up the old View menu. Right-clicking the gray area just below the page address also allows you to display the Bookmarks Toolbar.)
Right-click on the Bookmarks Toolbar (or Mac equivalent of right-click!) and choose New Bookmark.
Paste the code into the Location box (the second box).
Then type a useful name in the Name box (e.g., Oldstyle Picture) and click Add.
Now, when you want to tweak the image display, click the button to run the script.
Manual clicking is a hassle, so it might make sense to look into other solutions. (Greasemonkey didn't seem to work; I think it might not run on .jpg files.)

Quicktime export contains random grey frames

Lately, doing a straight Quicktime export (not Quicktime conversion) is resulting in movies with random grey frames in them, lasting about 12 frames or so each. This is HD footage, shot on the Panasonic DVX-100. This only seems to happen when exporting certain sequences, but I haven't been able to establish a pattern as to why it's happening on certain exports but not on others. It's all footage shot, ingested, and edited on sequences with the same exact settings.
It's only been happening since upgrading to QT 7.5, but the other computer in the office also upgraded, and it hasn't encountered this problem, and can export the same sequences I'm having problems with just fine.
Has anyone else experienced this, or offer a solution?

for the record this was not my first post, I forgot my account info. I'm normally very nice but studio x was just puffing his chest and belittling a good question
This is a Final Cut issue. If it were only a drive/scsi issue the errors would also be there in the animation codec as well. The bad frames ONLY occur when doing a quicktime export [DVCPRO HD 720](referenced, render all frames, and self contained). I'm not dismissing the fact that there very well may be a drive causing problems (G-SPEED XL12).
The bad frames do not occur any other time. I render plenty of things in the exact same codec over the network to the raid from AE and Motion and never ever have a problem.
One thing I am doing differently now is long form projects. The projects having issues are a one hour show and a two hour+ show. I don't have this problem with commercials or other small packages. It also doesn't matter if it's a random 10 sec section exported or the whole program.
This is what I'm working with:
HVX200 and other mixed footage
FCP and QT last updated in early july (no internet connection)
G-SPEED XL12
Fibre channel to one station that also acts as a file server
gigabit to one station from the file server
trunked gigabit to another station from the server (seperate NIC)
All three stations exhibit the same problem including the station connected via Fibre Channel
Other people are having the same problem as I've found by searching. The earliest report of this specific issue I've found so far was stated around Jan of this year. But there are more reports from this summer.

Grey frame around relinked images

Sometimes (but I think not always) when I relink a placed image I get a double grey frame around the image.
This is not a major problem but just kind of irritating and it seems to go away on its own after a few mouse clicks or something, but is it normal behaviour and can it be avoided?
Here's a shot to show what I'm on about. (In this example the image is masked as indicated by the extra white space at the top.)

I'm on CS3.
I didn't ask for isolation mode, so why am I getting it? (If that is indeed what it is.)
Also the layer palette opens so I can suddenly see all the sub layers. I didn't ask for that either. This only seems to happen randomly when I relink an existing placed image.
I read (again) what it says in the Help file about isolation mode but there doesn't appear to be any locking or dimming of other objects, so maybe that's not what it is. I have never wittingly used isolation mode in several decades of Illie usage; never really saw the point of it although I had read about it and even experimented with it. Instead I use Select Inverse (with a keystroke) and Lock or Hide if I need to isolate a bit of the artwork to work on. It seems a more reliable way of working and no nasty surprises :-)

JavaHelp and JavaWebStart

I am developing a JavaWebStart application. I would like to use Javahelp with it.
Is this possible?
Has anyone done this?
Would each user have to install JavaHelp on their workstation?
I know I can download the JavaHelp jar files via jnlp, but how would I set the JHHOME variable?
Thanks,
Jim

I didn't try the demo apps, I went and added JavaHelp to my application. This part was the same as the demo apps. I then added the following to my .jnlp file under resources:
<extension name="JHelp" href="jnlp/jhelp.jnlp"/>
I then created the jhelp.jnlp file as follows:
<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://localhost/ccs" href="jnlp/jhelp.jnlp">
     <information>
          <title>JavaHelp</title>
          <vendor>Sun Microsystems, Inc.</vendor>
     </information>
     <resources>
          <jar href="lib/jh.jar"/>
     </resources>
     <component-desc/>
</jnlp>
That was all that's to it.

Make a temporary, backup copy of your library if you don't already have one (Control-click on the library and select Duplicate from the contextual menu) and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Ringtones i purchased from itunes disappeared when my iphone 4s restarted and they only show up as 'on my device' in itunes library but with a grey dotted circle. How do I get them back? They worked until the phone restarted!

I purchased some alert tones on my iphone 4s via itunes yesterday. They all worked just fine until the phone ran out of battery and I plugged it in and restarted. They have vanished from the phone and when I connect to my PC they only show up as 'on my device' under tones and with a grey dotted circle by them. How do I get them back? This is crazy! I purchased one a second time, it worked, I switched my phone off and on again and it has gone again!!!

Having the same issue on multiple alert tones on my Iphone5c. After purchase they disappear from the phone and show up on my itune under Tones grayed out with a dotted circle next to them.

Trying to rebuild my iphoto library from time machine backup and it still says 0 restored with a grey screen and the circle. How can i restore my library?

I just bought a new Macbook pro and i tried to rebuild my iphoto library from a time machine backup on an external hard drive. Even after pressing command+option when starting iphoto and selecting rebuild library from automatic backup, it still doesn't work with the grey screen with the white circle and a little window that says 'rebuilding library: 0 versions restored'. I also tried to make a copy of my iphoto library but that did not work either. how can i restore my iphoto library or at least gain access to my photos?

Your question is not clear
Rerairing or rebuilding the iPhoto library never involves using Time Machine in any way
TM is a totally seperate program and you can "restore" a file (including the iPhoto library) from the past using TM - you launch TM and go back to the time you want and select the file (or folder or package) you want and click restore - it probably is best to keep the current one until you are sure everything is good

CS2 is very old and reached its "end of life" a while back. So probably won't run on modern operating systems. If you can still run it, you'll need to uninstall what you have and re-install with the download link below to activate it.

Problem with rendering still frame capture in FCP7

I'm a hack, so let's keep that in mind as I ask this question....but I *did* try to look through the forum for a similar issue before I created this post.
My situation: I am pulling some HD video from a Canon Vixia into FCP and basically just piecing it together with some minor editing to match music beats, etc. for some local sports leagues. Generally I find no issues with FCP, although I've only been dabbling with it for a few months.
My problem: My latest creation here: http://anothermotherproductions.smugmug.com/Movies/2011-Lacrosse-sample-movie/17 693649_L5rr8X does something annoying. I pulled a still frame from the video clip to let it hang there for a few seconds. See the 1:01 mark. The still frame looks clear in FCP, but when exported (and I've tried a few different formats, like h.264, pro-res, and "sharing" it for iPod) the image is ugly - looks like a motion blur from an old TV or something.
I've checked that the last frame of the video clip is the frame BEFORE the still frame, so walking step by step through the sequence reveals a normal sequence of motion, with the final frame "hanging" there for a while because its the still frame.
Make sense?
Anyone have constructive input?
Thanks.

Thank you so much - that helped tremendously. Image looks great now, AND I learned something.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Red square with circle, grey exclamation point AND iTunes won't sinc new songs?

I have just upgraded my iPhone 4 to iOS 7.0.3 and for some reason my music on my phone will not play. Every song comes up with a red square with a red circle around it and simply will not play. Looking on iTunes now - every time I try to play a song a grey exclamation point with a grey circle pops up next to the song and again WILL NOT PLAY!
I've heard that it iTunes might be having trouble finding the source of the song (which its never had trouble doing before) so I deleted one song and tried to replace it back on there only to find that it is now not sincing new songs either! This new song is very light grey in colour and has the spotted circle next to it.
I don't even know where to start fixing these problems.
Additional Information:
I have my phone set up to Sinc only checked songs and videos.
I drag and drop my songs into the 'On this iPhone' heading rather than sicing the whole thing as I share this computer with my brother.
Am I going to have to downgrade my iOS back to what it was?
I really hope someone out there can help!

[[UPDATE]] SOLVED - I've restarted both my computer and my phone and tried to re-drop in that one song that was coming up light grey. It's now sinced and playing on Itunes and is the ONLY song on my phone. No more exclamation mark or red square.
Looks like I'm going to have to delete all the songs and replace them into my itunes.
*sigh*
Thank you Apple for this smooth, easy going update. Much appreciated.
