Hai Friends,

Iam using J2ME , i can read a text file from jar (in res folder) by using

InputStream is = getClass().getResourceAsStream("help.txt");
StringBuffer sb = new StringBuffer();
try{
int chars, i = 0;
while ((chars = is.read()) != -1){
sb.append((char) chars);
}
return sb.toString();
}catch (Exception e){}

but i want write a data to the text file, i doknow how to write please any one help me for this problem.

Writing to file in JAR archive is not possible, only reading is allowed. I'm not sure what you are doing, as what you trying to write/store, but you have generally two options

1. Record Management System - RMS that is essentially mini database
2. PDA Optional Packages is JSR 75 that late you use FileConnection object, but this is often used for remote access (URL/OBEX/Bluetooth)
