[rules-users] class loading issue with websphere 6.1

[Vishal Joshi]

This is resolved now.
For benefit of others, i added the system variable in websphere console
drools.compiler=JANINO
This at runtime uses janino compiler api instead of using eclipse compiler,
which seems to have conflict with the websphere app server's internal
eclipse API.
