Executing java applications

[hajk@xs4all.nl ()]

I'm running Debian-Linux 1.2.6 with Java support, to be able to 
run Java applications (not applets). My little test program
Welcome.java is supposed to write a short message to the screen;
it compiles successfully with guavac (it says so), resulting in
Welcome.class. But then what? 

First, Welcome.class isn't executable. After fixing that, an error
message complains that it can't find /usr/bin/java -- and sure enough,
it isn't there, and neither is /usr/bin/guava. 

Am I missing something? Is Debian-Linux missing something? Must we
only run applets (e.g. under Netscape)? Would appreciate some help 
on this.
