Ok, I just found out the following:

The "Scanner" class, which you were missing first, is in the polyglot
jar file. The "jasmin.Main" class is obviously part of Jasmin. So the
following works for me:

soy ~/temp $ java -cp
sootclasses-2.2.3.jar:jasminclasses-2.2.3.jar:polyglotclasses-1.3.2.jar:.
soot.Main -O Hello
Soot started on Wed Feb 28 20:31:05 EST 2007
Transforming Hello...
Writing to sootOutput/Hello.class
Soot finished on Wed Feb 28 20:31:07 EST 2007
Soot has run for 0 min. 1 sec.
