running a compiled program using 'java' command fails, 'sablevm' succeeds

hi,
with debian-unstable on an i386, sableVM-1.11.3, jikes compiler,
 java -version
SableVM version 1.11.3
- compile date and time: 2005-04-07 23:38:28 UTC
- gcc version: 3.3.5 (Debian 1:3.3.5-12)
- 'real life brokenness' features enabled
- signal based exception detection
- copying garbage collection
- bidirectional object layout
- inline-threaded interpreter
#javac Program.java , compiles .class fine, but
# java Program , failes with:
#java.lang.ClassNotFoundException: Program not found in 
java.lang.ClassLoader$1{urls=[file:/usr/local/share/sablevm-classpath/libclasspath.jar], 
parent=null}

 #sablevm Program runs fine?
.bash_profile:
PATH=/usr/bin:"${PATH}"
JAVA_HOME=/usr/local/lib/sablevm
export JAVA_HOME
PATH=$PATH:/usr/bin/:/usr/local/lib/sablevm/bin:/usr/local/bin:/usr/local/bin
CLASSPATH=/usr/local/lib/sablevm/jre/lib
export CLASSPATH
