Javax.comm API on 64-bit Windows

This is how I got it to work.
I’ve tested it using JDK 1.6 (32bit) on my Windows 7 64bit machine.

  1. Install 32bit JDK.
  2. Copy ‘win32com.dll’ to JDK_HOME\jre\bin.
  3. Copy ‘javax.comm.properties’to to JDK_HOME\jre\lib.
  4. Copy ‘comm.jar’to to JDK_HOME\jre\lib\ext.

Now run your program and it should work.
