How to resolve IOException while listing all the filese from memory card?

[ajitkumar26]

Hi All,

I am trying to list all the files and folders from the memory card in thr Dopod-T4288 device.

I wrote the code in J2ME as Dopod-T4288 supports J2ME.

Its working fine for DOPOD-S1 and DOPOD-P660 devices and also on Dopod-T4288 device it is working properly for phone memory.

But when trying to list the all the files and folder under memory card it's giving the IOException.

Can any body help me to resolve this?

Please help me....as soon as possible.

Thanks in advance...

Thanks & Regards,

Ajit

Ajit, please note that the path for accessing the data from the Phone Memory and then Card Memory are different hence you might be getting the above exception due to the hard coded path inside your code. Get a call to the Enumeration drives = FileSystemRegistry.listRoots(); and then try to make the connection. I am sure that this you will get rid of this issue,

Thanks Raj for your reply.
Whatever you are saying is allready done.Please find my code snippet below
if (MEGA_ROOT.equals(currDirName)) {
e = FileSystemRegistry.listRoots();
browser = new List(currDirName, List.IMPLICIT);
} else {
currDir = (FileConnection) Connector.open("file://localhost/" + currDirName);
e = currDir.list(); browser = new List(currDirName, List.IMPLICIT);
// not root - draw UP_DIRECTORY
browser.append(UP_DIRECTORY, dirIcon);
}

The above code snippet listing all the drives.
But when I am selecting the memory card It's giving the IOException on the following line of code:
e = currDir.list();
When I am checking whether the drive is readable or not It showing not readable,not writable.and also not a directory but the drine is open.

Is there any setting need to be done in the device for read,write access to the meory card?

Please help me...
Thanks & regards,
Ajit

Can you try to run the PDAP demo available there in the app folder of the Sun Java Wireless Toolkit?

Check and revert..

Yes Raj, I am running the PDAP demo only.

I suspect that you are referring to the WTK's in built PDAP demo. If the same is not working and not able to access the data on the memory card and throwing IOException then you may ask this issue on the Windows DiBo.
