Helloword instances of the JBPM API

1. Create a new JBPM project

2. Under the SRC directory

Create a new HelloWorld package to import the following five files: helloworld.jpdl.xml

<?xml version= "1.0" encoding= "UTF-8"?>

<?xml version= "1.0" encoding= "UTF-8"? ><process name= "HelloWorld" xmlns= "HTTP://JBPM.ORG/4.4/JPDL" >   <start name= "Start1" g= "66,16,48,48" >      <transition name= "to submit Application" to= "Submit Request" g= "   -71,-17"/> </start>   <end name= "End1" g= "66,348,48,48"/> <task   name= "Submit a Request" g= "44,96,92,52" assignee= "employee" >      <transition name= "to department manager approval" to= "department manager approval" g= " -95,-17"/>   </task>   <task name= "department manager approval" G = "44,180,92,52" assignee= "department manager" >      <transition name= "to general manager approval" to= "general manager Approval" g= " -83,-17"/> </task   >   <task name= "general manager Approval" g= "44,264,92,52" assignee= "General Manager" >      <transition name= "to End1" to= "End1" g= "- 47,-17 "/>   </task></process>

2. Build JBPM environment, that is, import the corresponding jar package, not listed here, if you want to, please comment, and privately talk about my
3. Create a new package, such as Hellowordapi
and create a new class under this package, as follows
Package Cn.itcast.oa_hellowordapi;import Java.util.list;import Org.jbpm.api.configuration;import Org.jbpm.api.processengine;import Org.jbpm.api.task.task;import Org.junit.test;public class HelloWord_API {private        Static Processengine processengine=new Configuration ().
