FileConnection ConnectionNotFoundException

[mindus]

Hi,
we are implementing audio recording concept in our application. In that first create a file using fileconnection like

conn = (FileConnection)Connector.open("file:///"+test.amr,Connector.READ_WRITE);

While run the program its giving following exception:

javax.microedition.io.ConnectionNotFoundException: Only absolute file URL's of type <drive>path> are supported

Any idea about this exception, and anybody can tell me how to create a file in the nokia device?

Thanks

Actually the file system of nokia emulator support drives which you are not specifying in your code if you try ur code in default simulator of wtk it will run what you have to do is

1........Enumerate drives in filsystem from here

Result obtained from above is further used to create a dynamic path and then used in file connection url

I never tried on nokia simulator but on default simulators that netbeans provide however I do code the same way and dat works fine on nokia devices

WHy dont you try to print the output of the above scenario I told you and then hardcode teh path but literally I dont suggest hardcoding the path of your main code its for just testing purpose

[mindus]

I tried that logic

Enumeration drivesEnum = FileSystemRegistry.listRoots();
while (drivesEnum.hasMoreElements()) {
String drives = (String)drivesEnum.nextElement();
System.out.println("All Drives --->" + drives);

I am getting following output:

All Drives ---> C:/

And i am tried to execute the program file:///C:/test.amr

Now i am getting java.lang.SecurityException: Access denied Error.


Thanks

dont write in drive directly like this file:///c:/test.amr
but use some folder file:///c:/test/test.amr

[mindus]

Its not working. Same exception occured.

Its is need to give any permission on Jad file;

MIDlet-Permissions:

Which class to add in permissions



Thanks

You cannot give yourself permission. You can only write files in certain folders. Try this example.
