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.
I am using windows XP OS.
I have not done anything about the win32com.dll and javax.comm.properties file. Please tell me from where I should get these file or what will content of these files.
I am using Java1.6.
Sun no longer offer's the Windows platform binaries of javax.comm, however javax.comm 2.0.3 can be used for the Windows platform, by using it in conjunction with the Win32 implementation layer provided by the RxTx project. To use that, download javax.comm for the 'generic' platform (which provides the front-end javax.comm API only, without platform specific back-end implementations bundled). Then acquire the Windows binary implementation rxtx-2.0.7pre1 from http://www.rxtx.org.
