Problem with FramePositioningControl: number of frames = 0

Hi!
I have to access video frames (from MPEG-1 input data) in a not sequential order. I therefore tried to use Seek.java (http://java.sun.com/products/java-media/jmf/2.1.1/solutions/Seek.java).
If I use the code as is, it is not possible to instanciate the FramePositioningControl-object ("player does not support FramePositioningControl").
If I create a Processor instead of a Player and therefore replace the line
"p = Manager.createPlayer(ds);"
by
"p = Manager.createProcessor(ds);"
I am able to instanciate FramePositioningControl.
BUT:
"fpc.mapTimeToFrame(duration)" returns zero, even if I know that the duration is set to a non-zero-value.
And therefore the frame positioning with fpc does not work for me.
Could you maybe help?
Thanks in advance!

Luis,
let me explain to you how modplsql ( apex based on) is working. even if you have 1000 client users running your web app. it is not necessary that you will see 1000 oracle sessions. hitting links on your page will initiate a HTTP request then a http process will handle the request, then it connects to a database session, if your database responded to your http request quickly then the db session will be inactive, your http process will deliver the response to the client browser, the the http process will be ready to handle another request (be careful I am not saying another user it may be another click from the same user and it may be another click from another user, the connection between application server and db server is stateless I mean there is no specific db session dedicated to http process, connection pooling ).
suppose now that your db session did not respond quickly (having wait events, you can check on v$session) then the session will be active and the http will wait until the db responds, at that time if your user did another logout, login process or even tried to open another browser then a new http process will be created on the middle tier and so on until your users will consume all MaxClients even if you have 300.
to summarize check your application and see where your db session spending the time you can check that in v$session or in the EM it will be easier.
Good Luck

Problem with graphs on repeating frames

Is it possible to use graphs showing correct data within repeating frames?
We experienced problems with graphs within repeating frames, each occurrence of a graph shows the same picture (using data that corresponds to the first frame).
Tnx in advance.

Sounds like the source data for the Graph is the wrong Group.

Problem with file dialog (root frame)

Hi guys
I�m having a problem with open up a filedialog.
I have a rendered jlist and the are some items inside. The user, can right click any item and choose from a list some commands (print, save, update etc)
Everything works fine but when he clicks the SAVE option (again, right click and choose save)
FileDialog fd = new FileDialog(new JFrame(),"Save PAX list",FileDialog.SAVE);
I cannot use new JFrame() (as I did above) because it might block the application.
For this I�m trying to get the root by:
Component c = SwingUtilities.getRoot((Component)e.getSource());
JFrame myFrame = (JFrame)c;
And than:
FileDialog fd = new FileDialog myFrame,"Save PAX list",FileDialog.SAVE);
This get me a null frame :- (
Anyone?

The following worked on a "normal" menu item. I didn't test it on a "popup" menu item:
JMenuItem mi = (JMenuItem)e.getSource();
JPopupMenu popup = (JPopupMenu)mi.getParent();
Component c = SwingUtilities.windowForComponent(popup.getInvoker());
System.out.println(c);

Problem with random number generation

hey forum, i wonder if anyone can help me out with a small problem with my university coursework (yep its homework!!!)
heres my problem, i am writing one of them 8 puzzle problems (the one based around sam lloyds 15 puzzler), i can successfully generate one random sequence of numbers with no duplicates, but whenever i call the random method again it keeps producing the same results
heres the code
in my main class file
if(e.getSource() == randomButton) {
      new RandomPuzzle();
      System.out.println(random.randState);
      //startStateString = new RandomPuzzle();
}heres my number generator class file
import java.util.Random;
import java.io.*;
public class RandomPuzzle
     /** Base Random number generator */
    Random rn = new Random();
    /** Puzzle holder */
    byte b[];
    long number = 0;
    String randState = "";
    /** Default constructor */
    public RandomPuzzle() {
        rn.setSeed(number);
        b = new byte[9];
        randState = randomString();
    /** Provide range for generation */
    public int rand(int lo, int hi) {
        int n = hi - lo + 1;
        int i = rn.nextInt() % n;
        if (i < 0)
        i = -i;
        return lo + i;
    /** Set size for array */
    public int rand( int hi){
        int n = hi;
            return n;
    /** Check for duplicate values within the same configuration */
    boolean valueExists( byte value ) {
        int i = b.length;
        boolean exists = false;
        for( int j = 0; j < i; j++ ){
            if( b[j] == value )
                exists = true;
        return exists;
    /** returns the actual string */

            boolean valueEntered = false;
            byte temp = (byte)rand('0', '8');
            while( valueEntered == false ) {

}i've tried for hours to work this out, but i am stumped. if anyone can point me in the right direction, maybe point out the problem code and give one or two tips i would be forever in your debt
thanx in advance
korbitz

thanx for the help paulcw, but when i removed the seed code it done the same
but i added this to my main class and now it works fine
if(e.getSource() == randomButton) {
               RandomPuzzle temp = new RandomPuzzle();
               System.out.println(temp.randState);
               //startStateString = new RandomPuzzle();
          }thanx again for your help

Problems with the number three on the keypad

iphone 4: When I dial a phone number, all of the digits on the keypad work correctly. When prompted to enter an account number or PIN, or choose an option from a menu after I get connected to my party, the number three key often does not register. I thought I might have dropped the phone or something so I tried my wife's iphone 4 and it has the same problem as mine with the number three. Is there a "fix" or workaround for this and am I the only one with this problem?

But this is all me, and I do A LOT of scrolling back and forth to cross check facts and so on. Having to constantly switch between files would be a huge pain.
I guess it's a matter of work styles, but I'd much prefer to switch around among a batch of open chapters with a simple key combination, as opposed to scrolling back and forth through pages in linear fashion.
How would ID handle a document of this complexity?
With the limited information you've offered, I'd say I have experience with similar documents, (product catalogs/pricelists), that ID handled just fine, and other cases in which seemingly simple files choked it. I can say the same of Quark. No one can answer your question definitively; there are too many variables. Chances are it's not (only) the size and complexity of your document in itself that are causing your problems. There can be any number of hardware or OS issues contributing, to name a couple.

Packing instructions - problem with external number range

Hi Gurus:
I have a problem with configuring packing instructions. I have created a number range entry with external numbering (tx. OPIN), but when I want to create a new packing instruction in POP1, I get an error message: Manually-entered packing instruction ID cannot be checked (Message no. VHU01116). Can you please tell me how to avoid this error message?
The system works fine if the number range is set to internal. As a matter of fact, initially I did create a setting with internal numbering and conducted a couple of tests, but I had to change the "external" flag in the number range to meet business requirements. Is it possible that somehow the system does not recognize that I have changed the flag and I need to run some generation program or something similar?
I appreciate your valuable input
Tamas

For further records:
we have found the problem after debugging the function. In order for the system to accept the external number range, a second number range object with ID 02 must be maintained in OPIN. Then you can use this number range as external and keep the first as internal.

Retiming with same number of frames

Hi (couldn't find this) - If I want to convert my source video to a new frame rate -- but keep exactly the same number of frames -- what is the best way to do that?
Do I just set my desired frame rate in the Encoder tab and then set duration to 100% in the Frame controls? Does that give me the just the original frames in the source, but at a different speed?
Thanks, PH

OK -- I figured it out!

Problem with javascript cookies and frames in Safari

I have a web page with 2 frames in it. One frame holds a pulldown menu for quick navigation, which changes the content in the other frame and also writes a cookie that makes that choice the default when the user comes back to the web page. My problem is that when the page that has the navigation is in frames it will not change the cookie when the navigation choice is changed. It will only change the cookie if the navigation page is displayed on its own web page (not in frames). The javascript works fine in both FireFox and Google Chrome. It's only Safari that has this problem. Is this a bug in Safari, or do I need to code this differently? I also tried putting the javascript function in the main index.html page that sets up the frames, but that didn't help either.
