Ok, so you need to start using the Drools 5 APIs.<br>Please take a look at the Drools 5 documentation:<br><a href="http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-flow/html_single/index.html#d0e1375">http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-flow/html_single/index.html#d0e1375</a><br>
<br>In the section 3.2 <br><h2 class="title"><a id="d0e312">Using a Process in Your Application</a></h2><br>you will find the correct api's.<br>Greetings.<br><br><div class="gmail_quote">2009/11/2 Scott Stevenson <span dir="ltr"><<a href="mailto:scott.stevenson@datacert.com">scott.stevenson@datacert.com</a>></span><br>

<p class="MsoNormal">I'm trying to execute the result of the Process API and
running into<br>
problems most likely stemming from my ignorance. I'm creating a new<br>
process following the sample code from section 3.1.3.2 of the User<br>
Guide. My sample process consists of:<br>
1. StartNode<br>
2. ActionNode that prints Hello World<br>
3. EndNode<br>
<br>
What I don't understand is how to get my new process into a<br>
KnowledgeBase and KnowledgeSession for execution. I've tried the<br>
following (Drools 4 method, I believe) as well:<br>
<br>
AbstractRuleBase ruleBase = (AbstractRuleBase)<br>
RuleBaseFactory.newRuleBase();<br>
ruleBase.addProcess(createProcess());<br>
InternalWorkingMemory workingMemory = new
ReteooWorkingMemory(1,<br>
ruleBase);<br>
<br>
workingMemory.startProcess("org.drools.sample.workflow.dynamic");<br>
<br>
The result of the previous code is a RuntimeException (unable to execute<br>
Action). Inner exception is null pointer from inside the<br>
ActionNodeInstance class. Where am going wrong in implementing the<br>
Process API?<br>
<br>
Thank you,<br>
