Hi, all! I am fairly new to x-10 and very new to openremote, and I'm hoping someone can help direct me. I have set up a basic device (light switch) and ON and OFF commands, using a CM11a interface. I am using the openremote iphone app, and when I issue either of the commands, it works (yay!) – but then my openremote server crashes with the following output:

WARNING: RXTX Version mismatch
Jar version = RXTX-2.2pre1
native lib Version = RXTX-2.2pre2

Hoping this is something simple that you guys have seen before – I am encouraged that the command works, and so far I think I am really going to enjoy using openremote. Please let me know if you need more info... thanks


This yould be related to the RXTX native libs.
Which version of MAC are you using?

Hi Amy,

Were there any other errors printed after the segmentation fault?

Best regards,

No – the app crashes after that error.

You could try the RXTX native lib (librxtxSerial.jnilib) from here:
You need to replace the one from webapps/controller/WEB-INF/lib/native

Thanks, Marcus! That lib is giving me a different error:

ERROR HTTP\-Thread\-1: com.jpeterson.x10.GatewayException: Request com port /dev/tty.usbserial in use (Unknown Application).

I should note that I am using a serial-to-usb converter, since the old macbooks these days don't come with serial ports. (hah.) I had (falsely, it seems) assumed that it wouldn't be the culprit, since I am getting successful signals before the crash. I am not familiar with RXTX, but I guess some more research is in order. thanks for your help!
