I don't really know much about specific APIs, but standard java comes with a Scanner class that's pretty usefull for such tasks. Try to find an equivalent in your enviroment.

I would do it like this:

int c;
while ((c= isr.read()) != -1) {
   System.out.print((char)c);
}

casting -1 to a char has a two byte result 0xffff which isn't equal to -1 (chars are unsigned).

kind regards,

Jos
