Access restriction: The type SerialPortEventListener is not accessible due to restriction on required library C:\Program Files\Java\jre6\lib\ext\comm.jar

今天上了google查一下，原來只是eclipse的環境設定問題...
Windows -> Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and trstricted API -> Forbidden reference (access rules): -> change to warning
參考這裡

後來又找到另一篇
1. Open project properties.
2. Select Java Build Path node.
3. Select Libraries tab.
4. Remove JRE System Library.
5. Add Library JRE System Library.
這樣竟然也可以...
