Method
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)this.getClass().getResourceAsStream(srFile);
OutputStream os =fconn.openOutputStream();
byte[] buf = new byte[1024];
int len;
while ((len = is.read(buf)) > 0)

}
catch(IOException e)
{
System.out.println("Exception"+e.getMessage()) ;

Try this:
Before trying this: you have to check the SDCARD is there or not and
System.getProperty("fileconn.dir.memorycard")
Gives directly the path upto:
file:///SDCard/
and then your filename;
private void copyFromResToSDCard()
{
try
{
InputStream is=(InputStream)getClass().getResourceAsStream("/ManualRecords.db");
FileConnection fileconn=(FileConnection)Connector.open(System.getProperty("fileconn.dir.memorycard")+"ManualRecords.db");//Here set your Path with new fileName.db;
if(fileconn.exists())
{
fileconn.delete();
}
fileconn.create();
byte data[]=new byte[is.available()];
data=IOUtilities.streamToBytes(is);
OutputStream os=fileconn.openOutputStream();
os.write(data);
fileconn.close();
is.close();
os.close();
}
catch (Exception e)
{
System.out.println("=============="+e.getMessage());
}
}
Enough;
