java - listen for RFID scanner and print data -

-

i have rfid reader/scanner bought site e-gizmo , have manual here: low cost rfid reader manual. i've been trying work java , far, have 0 idea how this.

what want have class running on background(threading+listener? not sure.) waits rfid , store content of tag variable(string).

so far, got class read physical port of device. here code.

package data;  import com.fazecast.jserialcomm.*; import java.util.scanner;  public class comcontrol{     public static void main (string argsp[]){          serialport ports[] = serialport.getcommports();          for(serialport port: ports){             system.out.println(port.getdescriptiveportname());         }          scanner = new scanner(system.in);         int x = i.nextint();          serialport port = ports[x-1];          if(port.openport()){             system.out.println("port open");         }else{             system.out.println("port not available");             return;         }          port.setcomportparameters(9600, 8, 0, 0);         port.setcomporttimeouts(serialport.timeout_read_semi_blocking, 0, 0);         scanner data = new scanner(port.getinputstream());  //i had give try or guess..         do{             system.out.print(data.nextline());         }while(x<99);      } }

ive been browsing around , far, havnt found newbie friendly guides on how device work java.

what have in tools jserialcomm-1.3.10.jar , comm-2.0.jar
