Hi guys, i got a problem about using javax.comm.
I've downloaded the Windows version of
Java Commnunication API from java.sun.com.
I extracted the zip file, placed the comm.jar at c:\j2sdk1.4.0\jre\lib\ext folder.After that, i wrote a simple program to
test whether i can get any serial/parallel port object from CommPortIdentifier.getPortIdentifiers();. It returns an empty enumeration, meaning that none of my ports are detected.
However I have checked that com1 port is exist using hyperterminal.
Please let me know if you have any information regarding this issue.
I have RFID card reader and I am trying to read data from rfid card.
