jdk1.6
jbpm4.2
tomcat6
oracle9i
ant1.7
eclipse-jee-galileo-win32
2.配置JDK1.6
在系l\径上d
JAVA_HOME=c:\java\jdk16(我的JDK1.6安装目录)
CLASS_PATH=.;%JAVA_HOME%\lib\tools.jar;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\jre\lib\rt.jar;
3.配置ANT
在系l\径上d
ANT_HOME=c:\java\ant
path=%ANT_HOME%\bin
4.配置数据?使用Oracle,默认使用的是hsqldb)
(1)class12.jar复制到jbpm-4.2\lib目录下，否则找不到驱?br /> (2)q入c:\jbpm-4.2\install\jdbc目录修改文goracle.properties文gQ设|你自己的oracle数据库名、用户名和密?br /> 注意jbpm-4.2的根目录名称不能更改Q否则无法运行ANT
(3)修改c:\jbpm-4.2\install\build.xml,修改?lt;property name="database" value="oracle" /> <!-- {hsqldb | mysql | oracle | postgresql} -->
(4)q入c:\jbpm-4.2\installQ?q行 ant create.jbpm.schema,创建数据库脚本q在指定数据库中创徏?br />
4.配置Tomcat
(1)复制apache-tomcat-6.0.20.zip文g到c:\jbpm-4.2\install\downloads目录?br /> (2)q入c:\jbpm-4.2\installQ运行ant install.tomcat.
完成后，在c:\jbpm-4.2目录下生成一个tomcat目录
5.配置eclipse
(1)复制eclipse-jee-galileo-win32.zip文g到c:\jbpm-4.2\install\downloads目录中?br /> 注意Qeclipse的名U必Leclipse-jee-galileo-win32
(2)q入c:\jbpm-4.2\installQ运行ant install.eclipseQ运行时间较?br /> 完成后，在c:\jbpm-4.2目录下生成一个eclipse目录
注意Q如果没有不用ant配置eclipseQ安装下面的GPDӞ提示出错Q点ȝ定后QGPD依然可以使用Q不知道Z么?br />
6.配置程设计器GPD
启动eclipse,在Eclipse里添加更新站点的ҎQ?br /> 帮助 --> 安装新Y?..
点击 d...
?d站点 对话框中Q单?压羃?..
扑ֈ install/src/gpd/jbpm-gpd-site.zip q点?'打开'
点击 定 ?d站点 对话框中Q会q回?'安装'对话?br /> 选择出现?jPDL 4 GPD 更新站点Q全部选中
点击 下一?. 然后点击 完成
接受协议
当它询问的时候重启eclipse
7.配置elcipse工程
配置jBPMQ?br /> 点击 Window --> Preferences
选择 JBoss jBPM --> jBPM-4.2 --> Runtime Locations
点击 Add...
?Add Location 对话框中Q输入一个名字，比如 jBPM-4.2 然后点击 Search...
?Browse For Folder 对话框中Q选择你的jbpm-4.2根目录，然后点击 OK
点击 OK ?Add Location 对话框中
8.定义一个用户库
用户库用来放|jBPM的库文g?如果你创Z个新工程Q?只需要将用户库全部添加到build path
点击H口 --> 属性（Windows --> PreferencesQ?br /> 选择Java --> 创徏路径 --> 用户cdQJava --> Build Path --> User LibrariesQ?br /> 点击新徏QNewQ?br /> cd名字jBPM Libraries
点击dJARsQAdd JARs...Q?br /> 扑ֈjBPM安装E序下的lib目录
选择lib下的所有jar文gq点L开QOpenQ?br /> 选择jBPM Libraries作ؓ入口
重新点击dJARsQAdd JARsQ?br /> 在jBPM的安装程序的根目录下选择jbpm.jar文g
点击打开QOpenQ?br /> 在jbpm.jar下选择源码附gQSource attachmentQ作为入?br /> 点击~辑QEditQ?br /> 在源码附件的配置QSource Attachment ConfigurationQ对话框中，点击目录QExternal Folder...Q?br /> 扑ֈjBPM安装E序下的src目录
点击选择QChooseQ?br /> 点击两次'定'QOkQ会关闭所有对话框
9.创徏一个jbpm demo
创徏一个例子，q将工作程定义保存到数据库?br /> (1)创徏一个java ProjectQv?#8220; myjbpm ”Q然后就可以单击“完成”?br /> (2)c:\jbpm-4.2\examples\src中的所有配|文件复制到myjbpm工程中的根目录下
jbpm.cfg.xml
jbpm.hibernate.cfg.xml
jbpm.mail.properties
jbpm.mail.templates.examples.xml
logging.properties
(3)修改jbpm.hibernate.cfg.xml
hibernate.cfg.xml 的默认设|是?HSQL Q这是一个内存数据库Q这U内存数据库用来代替目实际所用的数据库来做单元测试挺不错的。不q我们这里是要试试用 MySQL ?Oracle
MySQL 的更改如下：
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/jbpm</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">123456</property>
Oracle 的更改如下：
<property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@192.168.123.10:1521:wxxrDB</property>
<property name="hibernate.connection.username">xiong</property>
<property name="hibernate.connection.password">xiong</property>
(4)定义程
创徏程的定义文件是 pd.jpdl.xmlQ将下面代码复制到文件中
------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<process name="pd" xmlns="http://jbpm.org/4.0/jpdl">
<start name="start1" g="207,62,48,48">
<transition name="to state1" to="state1" g="-59,-17"/>
</start>
<end name="end1" g="208,293,48,48"/>
<state name="state1" g="185,155,92,52">
<transition name="to end1" to="end1" g="-47,-17"/>
</state>
</process>
------------------------------------------------------------------------------------------
(5)布置jbpm
import junit.framework.TestCase;
import org.jbpm.api.Configuration;
import org.jbpm.api.ExecutionService;
import org.jbpm.api.HistoryService;
import org.jbpm.api.ManagementService;
import org.jbpm.api.ProcessEngine;
import org.jbpm.api.RepositoryService;
import org.jbpm.api.TaskService;
public class ServicesTest extends TestCase {
public void testObtainServicesAndDeployProcess() {
Configuration configuration = new Configuration();
ProcessEngine processEngine = configuration.buildProcessEngine();
RepositoryService repositoryService = processEngine.getRepositoryService();
ExecutionService executionService = processEngine.getExecutionService();
TaskService taskService = processEngine.getTaskService();
HistoryService historyService = processEngine.getHistoryService();
ManagementService managementService = processEngine.getManagementService();
// 开始部|一个新的流E文?br /> String deploymentId = repositoryService.createDeployment().addResourceFromClasspath("pd.jpdl.xml").deploy();
}
}
无论?MySQL q是 Oracle Q?br /> jbpm4_deployment表，你会发现多了一条记?br /> jbpm4_deployprop表会多了三条记录,对应id,key,version
jbpm4_lob 表会多了一条记?保存程?br />
