How can I code to play audio continuously from page to page in iBooks for reflow ePub

Hi,
I have tried and successfully completed the iBooks ambient soundtrack option in Fixed Layout ePub. It works fine.
But while trying the same in Reflow ePub, it is not working in iPad iBooks. I have latest iBooks version and latest iOS version in my iPad.
Please let me know how can I code to play audio continuously from page to page in iBooks for reflow ePub?
Thanks,
Sundaram

As soon as the user turns to the next page, the audio stops.
That's how it works in all cases.
the book is a read aloud book.
See the 'How-To Read Aloud' section in iBA Tips and Tricks 01

wtf ? what the hell is that ?:-) I wonder how he does it without the EJB QL. Not that I want him to post it.

Creation Code EJB

Dear all,
is it possible to let Developer studio create the code for calling an ejb automatically?
the following code is actually always the same and it's not practical to type that code over and over again every time we want to call a method on an EJB...
InitialContext ctx = new InitialContext();
TestEJBLocalHome localHome = (TestEJBLocalHome)ctx.lookup("localejbs/TestEJBBean");
TestEJBLocal bean = localHome.create();
So it would be nice if there was a way to say to developer studio, this is the bean i want to use, please generate the code so i can call my method on it.
Kind regards,
J.

Joren,
Almost exactly what you need:
1. In NW IDE open Window -> Preferences
2. Navigate to Java -> Editor -> Templates
Got the idea?

One thing really needed is a example code forum ...continued...

were people can just drop in and post example code of what ever they like. then instead of asking question's over and over their would be a wealth of code snipets in one place.
then again it might not be such a good idea.

there would have to be someone or a group of people that check the code to keep it clean, and good java, so it might get a bit boggy and hard to maintain...
but a good subject, although i still think that there is sufficient examplecode to find.
You will practically never find exactely what you need online somewhere cause no application has the same possibilities, features...
dunno my 2 cents...

Replaced CPU same LED error code for CPU problem continues to occur

I have a dv6-1280us laptop that does not start. I can hear the optical and HDD, screen is blank the number lock and cap lock LED blinks once between pause. The chart indicates that the CPU needs to be replaced. I replaced the CPU with a new one from HP. I still am getting the same LED error code. Any suggestions on resolving this problem. Thanks.

It's either a corrupted BIOS or motherboard problem. Since you've already replaced the CPU, the only other option is to replace the motherboard.

How to code EJB in Eclipse IDE

(that how we add session beans, how we configure application server and how we generate entity beans)
do I need any plugin to work with J2ee in it,
Please help me - Thank u very much

Sorry, this forum is for questions about the javadoc tool for generating documentation, so you might try elsewhere.

Error when opening a EJB code

Hi All,
When I try to open by ejb code ( ejb.java file) I am getting the following error
An internal error occurred during: "Resynching JPA model ...".
IWAE0011E Key already used to access Resource : org.eclipse.wst.common.internal.emfworkbench.EditModelLeastUsedCache@e55d75
Please help me in this
Thanks!

Hi,
First check in
IMG-FA-FA GS - Tax on sales & Purchase
1. Check the calculation procedure - TAX<Country> E.g. for India - TAXIN
2. Check whether the country has been assignmed to the calculation procedure
3. Calculation - Define Tax codes for Sales / Pur - Enter country and enter tax codes (Tax Type: A: Output tax; v-Input Tax) and give Tax percent
Save
It should solve ur problem
<i>Pls. assign points, if useful</i>

EJB client recovery

Hi,
I have a java client application using EJBs, and talking to a EJB server (j2ee sdk 1.3) successfully.
Now I stop the EJB server while the client is running, and restart the server again. I would like my client to recover automatically without the need of stoppin/restarting it.
When the server stops, my client enters in a 'resume mode' when it tries to recreate new EJBs.
Unfortunately, when the server is back up and running, the creation of EJBs still raises a MarshallException and it even hangs after a while.
My approach is a bit innocent, but is there a smarter solution that would work?
Thanks

Try to do a clean up at the client code when u determine that the EJB server is down. Is the intent to failover to another ejb server and continue with the session then you may require Sun's enterprise edition which supports sfsb failover.

Could somebody pls help?
