I defined a process as the above.
between 2 script task there is a rule task.
here is my rule content. it's very simple.
============================================================
#created on: 2011/10/11
#list any import classes here.
import org.drools.runtime.process.WorkflowProcessInstance;
#declare any global variables here
rule rule1
ruleflow-group "validate"
when
then
System.out.println( "TEST RULE ^^^" );
end
=============================================================
and process content is as following.

========================================================================================================
in the first script task.
I have a code snippet to call fireAllRules in order to trigger rule task to work.
==================================================================
System.out.println("Before rule\n");
org.drools.runtime.StatefulKnowledgeSession ksession =
(org.drools.runtime.StatefulKnowledgeSession)
kcontext.getKnowledgeRuntime();
ksession.fireAllRules();
System.out.println("After rule\n");
===================================================================
and then I deployed all these artifacts to Guvnor repository by using Gnvnor plugin in
eclipse.
the I open a browser to http://localhost:8080/jbpm-console to start a process.
i have been trying many ways to try to fire a rule task to work.
however,
It always stops at rule task and can not mve to next script task.
I don't know why it goes this way.

log file is attached.
any suggest and help will be appreciated.
