Hi,
I've installed jBPM5.1 on a bare OS: Windows Server 2003. It had nothing else installed on it previously. I installed the latest version of the Java JDK and Ant and set them up appropriately (JAVA_HOME, ANT_HOME, both \bins in the Path). I ran ant install.demo.
So far so good.
In Eclipse, I tried to debug the first sample app: evaluation | ProcessTest.java. I got this error:
org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java:org.drools.rule.builder.dialect.java.JavaDialectConfiguration'

Obviously there's more, but that's all my Console pane would show.
Anyone know what's going on? What I'm possibly missing?
Curious: It looks like the root of the problem is "org.drools.RuntimeDroolsException: value '1.7' is not a valid language level", but I doubt Drools would refuse to run on a newer version of the JDK.
Thanks in advance for any help!
