Need help installing java app

[andrewwalker27]

I'm running ~Gentoo x86_64 and want to connect to my Psion Series5. The only app in portage, plptools, isn't available but I came across this java based app which seems better.

The only snag is that the instructions are in German!
Can anyone explain how to install this app, I have java installed but don't understand what else I'm supposed to install with regards to the link javax.comm. I've downloaded the package comm3.0_u1_linux.zip but don't know where to go from here.
Anyone out there who can help?

when you install javax.comm copy files form its dir to java lib dir as in example:

javax.comm.properties:
von /opt/IBM-Java2-141/jre/lib nach /usr/java/j2re.1.4.1_03/lib
comm.jar:
von /opt/IBM-Java2-141/jre/lib/ext nach /usr/java/j2re.1.4.1_03/lib/ext
libibmcomm.so:
von /opt/IBM-Java2-141/jre/bin nach /usr/java/j2re.1.4.1_03/lib/ext

von/nach -> from/to.

with mandrake javax.comm is installed in /opt dir and java in /usr/java.

now you need file jpl2alpha2.0.1.jar and you can place it anywhere. start java psion link with java -jar /home/frank/jpl2alpha.2.0.1.jar.
