My code is:
protected int readKeepMibResp onse(URLConnect ion connection)
throws IOException
{
int retIndex = -1;
String inputLine = null;
BufferedReader in = new BufferedReader(
new InputStreamRead er( connection.getI nputStream()));
while (//in.ready() &&
((inputLine = in.readLine()) != null) &&
!inputLine.equa ls(END_OF_RESPO NSE))
{
try {
util.Debug.prin t(this, "inputLine = " + inputLine);
retIndex = Integer.parseIn t(inputLine);
}
catch (NumberFormatEx ception e)
{
retIndex = -1;
}
}
in.close();
return retIndex;
}


Any idea?
Thanks
