Hi Luis,

RXTXcomm.jar needs to be on your CLASSPATH.

export CLASSPATH=/home/luis/rxtx/RXTXcomm.jar:.

librxtxSerial.so needs to be on your java library path.  The current 
directory should be fine for experimenting.  If there is version 
information in the filename you can just rename it librxtxSerial.so.

If you have problems, most of the issues are captured on the wiki:

If you have time, we could use an entry for installing the precompiled 
binaries on the wiki page - put your best attempt in as you figure it out:

I don't know what you found on sourceforge.  Many projects distribute rxtx 
to make life easier for users of their software.  If it is interesting to 
you, try contacting the person responsible for the page/submission.

All the best,
