I gave this a shot today after installing all the .deb's I used a simple java script for a test an got this as output

Nokia-N800-51-3:/home/user/dev# jikes foo.java

Found 1 system error:

*** Semantic Error: You need to modify your classpath, sourcepath, bootclasspath, and/or extdirs setup. Jikes could not find package "java.lang" in:
.

Any one got any ideas?
