[rules-users] How to execute a Process API result?

[ramram8]

Hi All

I am also trying to build a dynamic process to be used. I am having some
difficulties in the build where I having this exception below is the sample
code that I am using:

java.lang.NoClassDefFoundError: sample/Process_sample_0
	at
sample.Process_sample_0Action0Invoker.execute(Process_sample_0Action0Invoker.java:20)

Also I have a question can I use this dynamic process inside the GWT web
console? and How?

Please help in this issue

public static final void main(String[] args) 
	{
		try 
		{
			KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();

            org.drools.rule.Package p = new
org.drools.rule.Package("sample");
            RuleFlowProcess process = createProcess();
            p.addProcess(process);

            KnowledgePackageImp kpi = new KnowledgePackageImp();
            kpi.pkg = p;

            List<KnowledgePackage> list = new ArrayList<KnowledgePackage>();
            list.add(kpi);

            org.drools.compiler.PackageBuilder pbuilder = new
PackageBuilder();
            pbuilder.addPackage(p);
            org.drools.compiler.ProcessBuilder builder = new
ProcessBuilder(pbuilder);
            builder.buildProcess(process, null);
            
            kbase.addKnowledgePackages(list);

            StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();

            System.out.println("=======>>> process.getId()
["+process.getId()+"]");

			// starting the process
			ksession.startProcess( process.getId() );
			ksession.fireAllRules();
		} 
		catch (Throwable t) 
		{
			t.printStackTrace();
		}
	}
	
	
	public static RuleFlowProcess createProcess()
	{
		String processName = "org.drools.HelloWorldJoinSplit";
		RuleFlowProcessFactory factory =
		    RuleFlowProcessFactory.createProcess(processName);
		factory
		    // Header
		    .name("HelloWorldJoinSplit")
		    .version("1.0")
		    .packageName("sample")
		    // Nodes
		    .startNode(1).name("Start").done()
		    .actionNode(2).name("Action 1")
		        .action("java", "System.out.println(\"Inside Action 1\")").done()
		    .endNode(3).name("End").done()
		    // Connections
		    .connection(1, 2)
		    .connection(2, 3);
		RuleFlowProcess process = factory.validate().getProcess();
		
		System.out.println(" ====== >> ["+process.getId()+"]");
		return process;
	}
