I am trying to use Drools examples in eclipse 3.2 but when i run that
am getting runtime Excepion as follows.

java.lang.NoClassDefFoundError:
org/eclipse/jdt/internal/compiler/env/INameEnvironment
at org.drools.compiler.PackageBuilder.loadCompiler(Unknown
Source)
at org.drools.compiler.PackageBuilder.(Unknown Source)

at
src.main.java.org.drools.examples.StateExampleUsingAgendGroup.main
(StateExampleUsingAgendGroup.java:21)
Exception in thread "main"

Whats needed to be done to fix this and waht jar files are needed to put in plugin.

Thanks and regards
