On a very current Angstrom with a fresh install of java, the jar files do not work with a defined CLASSPATH:
20:13:30 Mon Jun 24 kensbone 532 /netrexx/examples/rosettacode → java -version
java version “1.6.0_18”
OpenJDK Runtime Environment (IcedTea6 1.8.2) (6b18-1.8)
OpenJDK Zero VM (build 14.0-b16, mixed mode)
19:42:13 Mon Jun 24 kensbone 527 /netrexx/examples/rosettacode → echo $CLASSPATH
/netrexx/lib/NetRexxC.jar:/usr/lib/jvm/java-6-openjdk/lib/tools.jar
19:43:27 Mon Jun 24 kensbone 528 /netrexx/examples/rosettacode → ls -l /netrexx/lib/

But if I put the jar file explicitly in the java command, then it finds all the classes:
19:44:20 Mon Jun 24 kensbone 530 /netrexx/examples/rosettacode → java -classpath .:/netrexx/lib/NetRexxC.jar HelloWorld
Goodbye, World!
19:45:10 Mon Jun 24 kensbone 531 /netrexx/examples/rosettacode → echo $CLASSPATH
/netrexx/lib/NetRexxC.jar:/usr/lib/jvm/java-6-openjdk/lib/tools.jar
19:47:22 Mon Jun 24 kensbone 532 /netrexx/examples/rosettacode →
the “jar” command does not seem to work on angstrom but I looked in the jar file with “jar -tf” on another system and it is in there.

Is this working as designed? Is it a bug? Do I have to live with it? Should I go to an Ubuntu release?
