USB communication with PC

Postby DeQiu » Thu Jan 17, 2008 7:07 pm

when i run program USBSend sample on my PC i got message:

error: Class names, 'usbsend' , are only accepted if annotation processing is explicity requested

I think i have to do something with library lejos.pc.comm. on my PC. What should i do step by step ?

I think you get that message if you do:

javac USBSend

instead of


To compile and run USBSend:

1. Check you have NXJ_HOME set up and %NXJ_HOME%\bin on your PATH. If leJOS is working this should be OK.

2. Set up the CLASSPATH

set CLASSPATH=%NXJ_HOME%\pccomm,jar;.

3. Run it:

java USBSend

Ups... I was a fool. exactly...I forgot to write an extension of the file USBSend :)
Thank you very much for all hints! Second step was exactly about what I wanted to ask.
Sending greetings :)
