try {
if( v != null )
form_podglad.append("FileConnection version is " + v +"\n");
else
form_podglad.append("FileConnection NOT AVAILABLE\n");
//now save it
String url = "file:///c/myfile.txt";
FileConnection fconn = (FileConnection) Connector.open( url, Connector.READ_WRITE );
if (!fconn.exists()) fconn.create();
OutputStream os = fconn.openOutputStream();
String msg="hello world!";
os.write( msg.getBytes() );
// now write data to the file
InputStream in = fconn.openInputStream();
form_podglad.append("I will read now...");
int red = 0;
while ((red = in.read()) != -1)
{form_podglad.append(" "+(char)red);
                    }//end while
fconn.close();
catch( Exception e ) {
form_podglad.append("EXCEPTION from FileConnection:" + e +"\n");
}
