Prior to invoking a read method on a socket call, I am setting a maximum time via the setSoTimeout(timewait) method. The problem is when the timeout happens and an exception is raised, I couldn't find a simple way to determine the current exception is related to expiration of the set time or not. I do not want to parse the text message of the exception and look for the string "Read timed out" as this may not be platform and release independent. I would like to check the expection just like other exceptions like if (e.getMessage().equalsIgnoreCase(bndexcp.getMessage()))
where bindexcp is an instance as given below: BindException bndexcp = new BindException();

Here is a portion of the code where socket read call is made after setting a time value:

     try
     { if (readtime > 0 )
           timewait = readtime; // milli secs
        else
           timewait = 20000; // default time
        do
        { icb.clSocket.setSoTimeout(timewait);
           strt_time = System.currentTimeMillis();
           num = icb.reader.read(msg, (32600 - bytes_left), bytes_left);
           if (num == -1)
           { icb.msglog.LogMsg("Connection lost on read", 1);
              return(-3); // jss
           }
           else
              icb.msglog.LogMsg("# Bytes read " + num, 8);
           bytes_left -= num;
           rc = irepCheckMsg(recv_buf, icb);
           icb.msglog.LogMsg("rc from irepCheckMsg " + String.valueOf(rc), 8);
           switch(rc)
           {
              case 0: return(0);
              case -3: return(-3);
           }
           timewait -= (int)(System.currentTimeMillis() - strt_time);
        }while(timewait > 0);
     }
     catch (Exception e)
     { icb.msglog.LogMsg(e.getMessage(), 1);
        if (e.getMessage().equalsIgnoreCase(iointexcp.getMessage()))
        { icb.msglog.LogMsg("IO exception encountered in read process", 8);
            return(-3); // jss
        }
        timewait -= (int)(System.currentTimeMillis() - strt_time);
        icb.msglog.LogMsg("timewait" + timewait + " ", timewait);
        if (timewait <= 100) /* previously it was 0 instead of 100 */
           rc = -2; /* assuming read timed out */
        else
           rc = IREP.check_exception(e);
        return(rc);
     }
