Here are some FAQ for anyone trying to use the OBID i-scan: Q: The hardware is connected correctly and the software is completely installed, but when I run TestRFID.bat it tells me it can’t find the reader. What is wrong?
A: You must have a tag on the reader in order for it to be detected. Place any tag on the reader and try again. Keep this in mind when you are using other programs as well.
Q: I created my application using and IDE like NetBeans or Eclipse and it generated a dist folder with an executable jar file, but when I try to run my program using this jar, it tells me it can’t find any COM ports. Why is this happening?
A: Executables created in this manner will not see the COM ports correctly. Try writing a build.xml script and running your program using the script and Apache ant.
Q: I copied the comm.jar and rfid.jar files into a folder that my program looks in to find them, but when I run my program it tells me it can’t find any COM ports. What is wrong?
A: You need to also copy the javax.comm.properties file into the folder with comm.jar and rfid.jar. If javax.comm.properties is not included with the libraries, the program will not be able to see the COM ports.
Hopefully these will be helpful for anyone trying to use this tool. Along with many more instructions, this FAQ is also contained in my Quick Start Guide for the OBID i-scan.
