Hi,
I am new to JBPM. I have just finished installing it and am able to lauch Eclipse plugin UI. I have imported a couple of example projects to test and play around with. When I try to execute the process with 'run as java application' I get the following error:
org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java:org.drools.rule.builder.dialect.java.JavaDialectConfiguration'

Can anyone shed any light as to how this can be resolved? Am I missing plugins or Drools Rule Engine?
