Hi, I am newbie to jBPM and I am using JBPM5.2.
I want to program a split process and get exception messages:
Exception in thread "main" java.lang.IllegalArgumentException: XOR split could
not find at least one valid outgoing connection for split null

forgive me for my bad english.
Thanks very much.
the source as below:
public class MainTest {
public static void main(String[] args) {

process.addNode(splitNode);
new ConnectionImpl(startNode, Node.CONNECTION_DEFAULT_TYPE, splitNode,

actionNode.setName("validUser");
DroolsAction action = new DroolsConsequenceAction("java", null);
action.setMetaData("Action", new Action() {
public void execute(ProcessContext context) throws Exception {
System.out.println("The user is an valid user.");
}
});
actionNode.setAction(action);
