You can find the listing of Source code SerialPortsAvail.java below. You can build a simple serial port program in Java that will check for the available serial ports (COM ports ) on a Windows System. Once you have managed to compile your code without any issue, for Eg jSerialComm JAR file not found error, j SerialComm JAR file missing error. before the JAR file while compiling and runningĬhecking for available serial ports using Java jSerialComm-2.9.0.jar YourSerialSourceCodeĭo not forget to add. The above code was compiled on a Windows System.

Once the code has compiled without any errors you can run the resulting class file as shown below. jSerialComm-2.9.0.jar YourSerialSourceCode.java Once you have downloaded the jSerialComm JAR file in a directory of choosing, you can compile the source code as shown below. Make sure that the version number of the jSerialComm JAR file is correct, It may change with time.

This tutorial will teach you how to program your serial port using java to communicate with a USB Virtual serial Port based device like Arduino, USB Multifunction DAQ,GPS devices etc It is meant as an alternative to RxTx and the (deprecated) Java Communications API'. ' jSerialComm is a Java library designed to provide a platform-independent way to access standard serial ports without requiring external libraries, native code, or any other tools. In our Java Serial port programming tutorial we will be using a third party library called jSerialComm library from Fazecast, Inc to open and control the serial ports.

Some of the user developed java serial port programming API's like RxTx are no longer maintained. Java Standard library no longer carries classes to communicate with the PC serial port. The PC will communicate with an Arduino connected to the USB virtual Serial port of the PC and exchange text information using a Java program. In this tutorial we will learn how to program serial port of a PC using Java programming language.
