Can not copy the database of res folder and write to the memory card

I developed a small application using blackberry jde 7.0. I want to copy the database (.db) of res folder and write to the memory card. When I run in the Simulator, it throws exception "FileNotFound". But the file is located in the res folder.

Help me guys...

Here is the code

 copyFile("/Demo.db","file:///SDCard/Databases/Demo.db");

//Copy to Memory card
public void copyFile(String srFile, String dtFile)
{
try
{
FileConnection fconn;
fconn = (FileConnection) Connector.open(dtFile,Connector.READ_WRITE);
//if(!fconn.exists()) // if file does not exists , create a new one
// {
// fconn.create();
// }
InputStream is = (InputStream)getClass().getResourceAsStream(srFile);
System.out.println("read" + String.valueOf(is.available()));
OutputStream os =fconn.openOutputStream();
byte[] buf = new byte[is.available()];
int len;
while ((len = is.read(buf)) > 0)
{
os.write(buf, 0, len);
}
is.close();
os.close();
}
catch(IOException e)
{
System.out.println("Exception"+e.getMessage());
}
}

The exception is

File not found

«When I run in the Simulator he throws exception "FileNotFound".»

Which line is the rise of this?

You might find the code in the sample application SQLiteDemo, which does almost the same thing, useful in the study to determine what went wrong.

  • Can not format the memory card

    Canon that PowerShot SX 10 IS reformatted not 16 GB SanDisk Ultra.  Camera says memory card error.  Everything else seems to work on the camera.  Is there a way to fix this?

    Your camera specifications say that it will work with the following cards, memory card SD/SDHC, MultiMediaCard, MMC Plus card, HC MMC Plus card.

    Some memory cards note their speeds by a "class." Canon cameras are recommended to be used with nominal class cards 4 to SD (Standard-definition movies) and class 6 for HD (high definition movies) or more because of the large amount of data written to the card. As long as map meets the following standards for the card, the memory card must be compatible regardless of class or the speed rating.

    SD

    		Standard Secure Digital card supports up to 2 GB capacity.

    SDHC

    		Secure Digital High Capacity currently supports up to 32 GB capacity.

  • Moto Q does not recognize the memory card

    I just added a 2 GB memory card that is approved for the Moto Q 9 M... For some reason, my phone does not recognize the memory card. In the memory section it shows the card is unknown.

    With a previous discussion, I saw, I did add the memory card on my PC. It does not recognize the card... Any ideas?

    Thank you

    Try formatting the card on your pc and then install it on the phone. If it's 2 GB sandisk it should work fine. If the phone or the card is left. Sometimes reformat card strives to set everything right.

  • Software JetDirect 380 X can not see the airport card in the laptop G4 PPC

    Hello

    I tried to add a customer to the airport. It's a LaserJet 1200. But the software that comes with the JetDirect tells me to install an Airport card in the laptop. Now I can join hpsetup and print to the LJ 1200. But in practice I have to disconnect from the internet and the map Airport.  So, I know the JetDirect and LaserJet 1200 work very well. I tried different settings on the airport, but nothing has really changed the software on the laptop not finding the Airport card.

    Now I have a WOW goes a Xsense MIH 130 Xrouter, then go to the Airport Express Terminal. All Mac desk top of page 933mh, 1.67 ghz powerbooks. I use OSX10.4 to 10.5.8.  I don't know if the router is the problem or if the parameter in the jetdirect should be changed to the ad-hoc to something else. Don't know how to do this. With it, do not see the map Airport, I can't do the enbedded 192.0.0.192. There are a lot of maybe if I do this or if I do this it might work. Since the configuration of the printer in the TCP/IP section page everything below the line, Config by: is not specified.

    Thanks for any advice.

    Well again I was able to get to the stage 1.6 (in 10.5.8 printing Center is not the same). I could remove the printer that was working on its own network of HP. But was unable to add a printer in 0SX 10.5. Perhaps through IP printing, but do I put as the address? It is the site of HP to get instructions on a 380 X and another printer.

    http://h20000.www2.HP.com/bizsupport/TechSupport/document.jsp?lang=en & CC = US & TaskID = 115 & prodSeriesId = 29789 & prodTypeId = 18972 & prodSeriesId = 29789 & objectid = c00257796

    Maybe I should to the left of the printer, but I've changed the SSID in the jetdirect to match the network. The IP printer 192.0.0.192 or 192.0.0.193 or just use the network name it was changed to?

    To close, but I thought a few times.

    WHEN I INSERT THE MEMORY CARD INTO THE COMPUTER NOTHING NOT SE PAST AND IT DOES NOT APPEAR IN MY COMPUTER SO I NEED TO KNOW IF ITS A SETTING OR A DRIVER OR IF ITS THE SLOT IN HIS CAR?

    ============================
    This card worked previously on this system?

    Certainly could be hardware related... other
    cards work on your system? This card works
    on other systems?

    Perhaps the card is not compatible with your system.
    For example, it can be a SDHC memory card.

    Perhaps the following links will enlighten us:

  • Got a new computer and can not copy the catalog on my USB key.

    I have a new Dell laptop and have downloaded Lightroom to my new computer. I tried my backup from my old computer catalog and he said: "the process cannot access the file because another process has locked a portion of the file. I already tried to delete the lrcat.lock file as Adobe said to do and it did not work. I have no idea what to do! Help, please!

    Close LR. Open Windows Explorer (Windows File Manager), or on the link for computer workstation work, Documents, or any other link that will open the Windows File Manager.

    Copy the LR catalog file which is normally located in a subfolder of your user account on the USB drive. Then copy it to your new computer, place it in the same WAY as it comes. You must also copy all your image files or if they are all on a disk external drive connect this external drive to your new computer. If all your images are on your internal drive and then when you copy them on they must also reside in the same WAY that they were on your old computer.

  • Cannot find the product key and can not use the gift cards to buy Windows 7 from retail store

    Original title: Let Down by Microsoft Retail store

    My daughter lives and breathes on his pc. We had some tough times lately, and of course, his computer has had too many problems. In February of this year, I bought a Win 7 Home Premium for his pc. Since we moved, so I can't find the package with the product key, or the disc. I have $75 in gift cards from Microsoft, I need to buy new win 7 hp. Almost all retailers (in store and online) competitive price a new copy for about $119. We have been saving, and with gift cards, I would have just enough money to buy win 7 hp for my daughter. I went to our Microsoft store in the Mall. (Don't forget I saved for about 6 weeks, we are on a budget, then gift cards have been a miracle!) Guess what? The only place that I can use the maps from Microsoft wants $199.99. To add insult to injury - I can't use gift cards for purchases in line-HELP! We waited 2 months just to be left out... I am very disappointed by Microsoft.
    I thought that we recorded our product with Microsoft when it was originally installed, but cannot find anyone. All solutions?

    If you have purchased windows is installed a keyfinder allows you to recover your product key.

    I think that the price of $119 is to upgrade xp/vista to windows 7.
    the $199 price is for the full version.
