I trying to create new object with ActionHandler event:
In processdefinition.xml:
<task-node name="test">
| <task swimlane="st">
| <event type="task-create">
| <action class="jbpm.Create"/>
| </event>
| ...
I have 2 class
Create class:
import org.jbpm.graph.def.ActionHandler;
| import org.jbpm.graph.exe.ExecutionContext;
|
| public class Create implements ActionHandler {
|
| private static final long serialVersionUID = 1L;
|
| public void execute(ExecutionContext executionContext) throws
Exception {
| System.out.println("=======");
| ListData list;
| list = new ListData("test");
| System.out.println("=======");
| String dt = list.getName();
| executionContext.setVariable("lt", list);
| executionContext.setVariable("dt", dt);
| }
| }
ListData class:
public class ListData{
| private String name;
|
| public ListData(){}
|
| public ListData(String name){
| System.out.println("=========="+name+"======");
| this.name=name;
| }
|
| public void setName(String name){
| this.name=name;
| }
|
| public String getName(){
| return this.name;
| }
|
| public String toString(){
| return name;
| }
| }
I deploy OK, when i run have this error:
14:42:40,500 INFO [STDOUT] =======
