try {
InputStream is = this.getClass().getResourceAsStream("/level01.txt"
StringBuffer sb = new StringBuffer();
int chr;
while ((chr = is.read()) != -1)
{
sb.append((char) chr);
is.close();
}
System.out.println(" > reading OK!"
}
catch (Exception e)
{
System.out.println(" > ERROR: Cant Read File ERR= " + e);
}

Hi,

Your while loop is incorrect. You have the is.close() inside the loop, so it will occur straight after the first character is read, then the next read() will throw an exception!

Any of the path names should work. eg, if file in jar="/res/level01.txt" then them do getResourceAsStream("/res/level01.txt&quot.

The loop you want is:

while ((chr = is.read()) != -1)
{
sb.append((char) chr);
}
is.close(); // NOTE OUTSIDE LOOP :-)

Hope this helps,

Steve
