I changed these two line to get it to work from my nokia.
*<%@ page contentType="text/vnd.wap.wml"%>*
* String ss1=new String(readbyte).substring(0,charcount);*
Need to print only the charaters read into the buffer.
You will get an error if the file is zero length so you could do a test
before String ss
E.G.
* if (charcount == -1) charcount=0;
String ss1=new String(readbyte).substring(0,charcount);
*
You could also do other test on length of the file with
File infile=new File("C:/TextFiles/" + filename + ".txt");
long strLen = infile.length();
