<p class=MsoNormal>Ok, so you need to start using the Drools 5 APIs.<br>
Please take a look at the Drools 5 documentation:<br>
<a

<br>
In the section 3.2 <o:p></o:p></p>
<h2>Using a Process in Your Application<o:p></o:p></h2>
<p class=MsoNormal style='margin-bottom:12.0pt'><br>
you will find the correct api's.<br>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>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>
