This is how I ran my dynamic process:
Public static final void main(String[] args) {
String xml =
XmlRuleFlowProcessDumper.INSTANCE.dump(createProcess());
System.out.println(xml);
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(
ResourceFactory.newByteArrayResource(xml.getBytes()), ResourceType.DRF
);
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if (errors.size() > 0) {
for (KnowledgeBuilderError error: errors) {
System.err.println(error);
}
throw new IllegalArgumentException("Could not parse
knowledge.");
}
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();
WorkflowProcessInstance pi = (WorkflowProcessInstance)
ksession.startProcess("com.datacert.workflow.dynamic");
}

Scott,
A process is also "compiled" before it is executable. To load a process
constructed using the API, either:
* load it as any other process by transforming it to XML first using
the XmlRuleFlowProcessDumper
* compile the process before adding it to your rulebase, using
ProcessBuilder.buildProcess(..)

Re: [rules-users] How to execute a Process API result?
Here is my attempt at using the Drools 5 API to execute my dynamically
created Process:
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
org.drools.rule.Package p = new
org.drools.rule.Package("sample");
p.addProcess(createProcess());
KnowledgePackageImp kpi = new KnowledgePackageImp();
kpi.pkg = p;
List list = new
ArrayList();
list.add(kpi);
kbase.addKnowledgePackages(list);
StatefulKnowledgeSession ksess =
kbase.newStatefulKnowledgeSession();
ksess.startProcess("org.drools.sample.workflow.dynamic");
I still get the same null pointer error. Perhaps the problem is in my
implementation of the Process API? The code under createProcess is this:
RuleFlowProcessFactory factory =
RuleFlowProcessFactory.createProcess("com.datacert.workflow.dynamic");
factory
.name("HelloWorldRuleSet")
.version("1.0")
.packageName("org.drools")
.startNode(1).name("Start").done()
.actionNode(2)
.name("Action")
.action("java", "System.out.println(\"Inside
Action 1\");").done()
.endNode(3).name("End").done()
.connection(1, 2)
.connection(2, 3);
return factory.validate().getProcess();
Thanks,
Scott

Subject: Re: [rules-users] How to execute a Process API result?
Ok, so you need to start using the Drools 5 APIs.
Please take a look at the Drools 5 documentation:
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-flow/htm
l_single/index.html#d0e1375
In the section 3.2
Using a Process in Your Application
you will find the correct api's.
Greetings.

Are you working just with the Drools 4 version?
Or you can jump to the Drools 5 version?

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