Java Communications API

related links:
For my thesis I need to use a RS323 port, to receive data from a RFID reader. Therefore I needed to install the Java Communications API, to enable Java communicating with serial and parallel ports. Well the problem was that the installation instruction coming with the API say you need to install the comm.jar to $JDK_HOME\lib directory, which doesn't work for JDK 1.5! Thanks to this post in the Sun Java Forums, I was able to get the API work. The solution is simple, you have to copy the comm.jar to $JDK_HOME\jre\lib instead of $JDK_HOME\lib!
