2.
(准备 - Reserved - 处理) - 挂起
3.
(创建 - 准备 - Reserved - 处理) - 错误|退出|忽略
7.

创建knowledge base
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("MyProcess.bpmn"), ResourceType.BPMN2);
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
创建Session
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
ProcessInstance processInstance = ksession.startProcess("com.sample.MyProcess");
添加或移除监听器
ProcessEventListener
15.
整合jBPM 和 MyEclipse8.6
1.
下载GEF
http://www.eclipse.org/downloads/download.php?file=/tools/gef/downloads/drops/3.5.2/R201002241200/GEF-ALL-3.5.2.zip&url=http://download.actuatechina.com/eclipse/tools/gef/downloads/drops/3.5.2/R201002241200/GEF-ALL-3.5.2.zip&mirror_id=385
2.
复制步骤4中已经下载的包
drools
---------
drools-5.2.0.M1-eclipse-all.zip
jbpm
---------
jbpm-5.0.0-eclipse-all.zip
3. 解压并安装插件-链接方式
Drools
---------
E:\bisoft\tools\myeclipse\myplugins\drools520\eclipse
E:\bisoft\tools\myeclipse\myplugins\drools520\eclipse\features
E:\bisoft\tools\myeclipse\myplugins\drools520\eclipse\plugins
E:\bisoft\tools\myeclipse\myplugins\drools520\eclipse\plugins\lib\*.jar
注意上面的lib目录下的包是安装目录下的lib目录及子目录下的所有JAR包.为了方便,我都放到lib目录下.为什么这样做?因为drools的包依赖这些包,所以必须的.
jbpm
-------
E:\bisoft\tools\myeclipse\myplugins\jbpm5\eclipse\plugins
gef
-------
E:\bisoft\tools\myeclipse\myplugins\gef\eclipse\features
E:\bisoft\tools\myeclipse\myplugins\gef\eclipse\plugins
注意这里的GEF不能用前面步骤4的GEF SDK包,因为MyEclipse使用Eclipse3.5,因此要下载3.5对应的GEF SDK包.
链接文件
-------
E:\bisoft\tools\myeclipse\dropins\drools520.link
path=E:\\bisoft\\tools\\myeclipse\\myplugins\\drools520
E:\bisoft\tools\myeclipse\dropins\gef.link
path=E:\\bisoft\\tools\\myeclipse\\myplugins\\gef
E:\bisoft\tools\myeclipse\dropins\jbpm5.link
path=E:\\bisoft\\tools\\myeclipse\\myplugins\\jbpm5
4. 配置JBPM运行时
指向runtime目录
5. 导入例子
sample\evaluation
6. 配置JBOSS_HOME
指向jboss-5.1.0.GA
7. 复制build.xml到工程下,并修改
<?xml version="1.0" encoding="UTF-8"?>
<project name="jBPM5">
<property name="install.home" value="E:/bisoft/sharelib/jbpm-installer" />
<property name="jboss.home" value="E:/bisoft/jboss-5.1.0.GA" />
<property name="jboss.bind.address" value="localhost" />
<!-- ############ START/STOP ############ -->
<!-- Start H2 server -->
<target name="start.h2">

<exec executable="${jboss.full.path.win}" spawn="on"

</waitfor>
<fail if="jboss.timeout" message="jboss did not start within 5 minutes"/>
</target>
<!-- Stop JBoss AS -->
<target name="stop.jboss">
<exec executable="${jboss.home}/bin/shutdown.bat"
os="Windows 7,Windows Vista,Windows XP,Windows 2000,Windows 2003">
<arg value="-s" />
<arg value="jnp://${jboss.bind.address}:1099" />
<arg value="-S" />
</exec>
</target>
<!-- Start Human Task Service -->
<path id="classpath.human.task">
<fileset dir="${install.home}/runtime" includes="**/*.jar"/>
<fileset dir="${install.home}/db/driver" includes="**/*.jar"/>
</path>
<target name="start.human.task">
<mkdir dir="${install.home}/task-service/target"/>
<javac srcdir="${install.home}/task-service/src" destdir="${install.home}/task-service/target" classpathref="classpath.human.task">
<compilerarg value="-Xlint:unchecked"/>
</javac>
<copy todir="${install.home}/task-service/target">
<fileset dir="${install.home}/task-service/resources"/>
</copy>
<java classname="org.jbpm.DemoTaskService" fork="true">
<classpath>
<pathelement path="${install.home}/task-service/target"/>
<path refid="classpath.human.task" />
</classpath>
</java>
</target>
<!-- Start Demo -->
<target name="start.demo" depends="start.h2,start.jboss,start.human.task" />
<!-- Stop Demo -->
<target name="stop.demo" depends="stop.h2,stop.jboss" />
</project>
前面的两个属性根据实际情况修改.
8. 启动H2数据库, JBOSS, 人工服务
start.demo
9. 运行或调试ProcessTest
10. 如果你的BPMN文件没有对应的编辑器,可以运行这个类并将输出的信息复制到
myeclipse/configuration/org.eclipse.equinox.simpleconfigurator/bundles.info的最后, 然后删除configuration/org.eclipse.update目录并重启MyEclipse.
package com.sample;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
@SuppressWarnings("unchecked")
public class CreatePluginsConfig {
public CreatePluginsConfig() {
}
public static void main(String[] args) {
// 插件位置
String plugin = "E:\\bisoft\\tools\\myeclipse\\myplugins\\drools520";
new CreatePluginsConfig().print(plugin);
}
public void print(String path) {
List list = getFileList(path);
if (list == null) {
return;
}
int length = list.size();
for (int i = 0; i < length; i++) {
String result = "";
String thePath = getFormatPath(getString(list.get(i)));
File file = new File(thePath);
if (file.isDirectory()) {
String fileName = file.getName();
if (fileName.indexOf("_") < 0) {
print(thePath);
continue;
}
String[] filenames = fileName.split("_");
String filename1 = filenames[0];
String filename2 = filenames[1];
result = filename1 + "," + filename2 + ",file:/" + path + "\\"
+ fileName + "\\,4,false";
System.out.println(result);
} else if (file.isFile()) {
String fileName = file.getName();
if (fileName.indexOf("_") < 0) {
continue;
}
int last = fileName.lastIndexOf("_");// 最后一个下划线的位置
String filename1 = fileName.substring(0, last);
String filename2 = fileName.substring(last + 1, fileName
.length() - 4);
result = filename1 + "," + filename2 + ",file:/" + path + "\\"
+ fileName + ",4,false";
System.out.println(result);
}
}
}
public List getFileList(String path) {
path = getFormatPath(path);
path = path + "/";
File filePath = new File(path);
if (!filePath.isDirectory()) {
return null;
}
String[] filelist = filePath.list();
List filelistFilter = new ArrayList();
for (int i = 0; i < filelist.length; i++) {
String tempfilename = getFormatPath(path + filelist[i]);
filelistFilter.add(tempfilename);
}
return filelistFilter;
}
public String getString(Object object) {
if (object == null) {
return "";
}
return String.valueOf(object);
}
public String getFormatPath(String path) {
path = path.replaceAll("\\\\", "/");
path = path.replaceAll("//", "/");
return path;
}
}
11.
结果
12.
stop.demo
这里有个缺陷, 没有停止人工服务. 因此必须到任务管理器去结束进程.
13.
完成.
