上个周末女朋友考试去了，闲得慌，浏览D盘发现里面有个osworkflow 2.7,自己向往工作流已久(上个月写了一个基于jgraph的工作流流程可视化配置程序，
人家给我的只有一个xml流程文件的格式,自己对工作流也不甚了解),无事就拿来学学，我的java史也有才4个月了，呵呵

1.在mysql上建立shop数据库,把/etc/deployment/jdbc/mysql.sql 脚本执行，建立数据表

2.在jboss中建立数据源jdbc/mySQL-shop,server/default/deploy目录下得mysql-shop-ds.xml内容如下(不过要记得下载mysql的jdbc驱动)
<?xml version="1.0" encoding="UTF-8"?>
<!-- $Id: mysql-ds.xml,v 1.3.2.1 2004/12/01 11:46:00 schrouf Exp $ -->
<!--  Datasource config for MySQL using 3.0.9 available from:
http://www.mysql.com/downloads/api-jdbc-stable.html
-->
<datasources>
  <local-tx-datasource>
    <jndi-name>jdbc/mySQL-shop</jndi-name>
    <connection-url>jdbc:mysql://127.0.0.1:3306/shop</connection-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <user-name>root</user-name>
    <password>mysql</password>
    <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
    <metadata>
       <type-mapping>mySQL</type-mapping>
    </metadata>
  </local-tx-datasource>
</datasources>

3.将osworkexample.war 解压缩到 webapp目录 webapp可以在任何地方
修改webapp/WEB-INF/classes下得osworkflow.xml文件 内容如下
<osworkflow>
    <persistence class="com.opensymphony.workflow.spi.jdbc.MySQLWorkflowStore">
  <property key="datasource" value="java:jdbc/mySQL-shop"/>
  <property key="entry.sequence"   value="select count(*) + 1 from os_wfentry"/>
  <property key="entry.table" value="OS_WFENTRY"/>
  <property key="entry.id" value="ID"/>
  <property key="entry.name" value="NAME"/>
  <property key="entry.state" value="STATE"/>
  <property key="step.sequence" value="select sum(c1) from (select 1 tb, count(*) c1 from os_currentstep union select 2 tb, count(*) c1 from os_historystep)"/>
  <property key="history.table" value="OS_HISTORYSTEP"/>
  <property key="current.table" value="OS_CURRENTSTEP"/>
  <property key="historyPrev.table" value="OS_HISTORYSTEP_PREV"/>
  <property key="currentPrev.table" value="OS_CURRENTSTEP_PREV"/>
  <property key="step.id" value="ID"/>
  <property key="step.entryId" value="ENTRY_ID"/>
  <property key="step.stepId" value="STEP_ID"/>
  <property key="step.actionId" value="ACTION_ID"/>
  <property key="step.owner" value="OWNER"/>
  <property key="step.caller" value="CALLER"/>
  <property key="step.startDate" value="START_DATE"/>
  <property key="step.finishDate" value="FINISH_DATE"/>
  <property key="step.dueDate" value="DUE_DATE"/>
  <property key="step.status" value="STATUS"/>
  <property key="step.previousId" value="PREVIOUS_ID"/>
  <property key="step.sequence.increment"   value="INSERT INTO OS_STEPIDS (ID) values (null)"/>
  <property key="step.sequence.retrieve"   value="SELECT max(ID) FROM OS_STEPIDS"/>
 </persistence>
    <factory class="com.opensymphony.workflow.loader.XMLWorkflowFactory">
        <property key="resource" value="workflows.xml" />
    </factory>
</osworkflow>

4.修改webapp/WEB-INF/classes/osuser.xml文件
<opensymphony-user>
    <provider class="com.opensymphony.user.provider.jdbc.JDBCAccessProvider">
  <property name="user.table">os_user</property>
  <property name="group.table">os_group</property>
  <property name="membership.table">os_membership</property>
  <property name="user.name" >username</property>
  <property name="user.password">passwordhash</property>
  <property name="group.name">groupname</property>
  <property name="membership.userName" >username</property>
  <property name="membership.groupName">groupname</property>
  <property name="datasource">java:jdbc/mySQL-shop</property>
 </provider>
    <provider class="com.opensymphony.user.provider.jdbc.JDBCCredentialsProvider">
  <property name="user.table">os_user</property>
  <property name="group.table">os_group</property>
  <property name="membership.table">os_membership</property>
  <property name="user.name" >username</property>
  <property name="user.password">passwordhash</property>
  <property name="group.name">groupname</property>
  <property name="membership.userName" >username</property>
  <property name="membership.groupName">groupname</property>
  <property name="datasource">java:jdbc/mySQL-shop</property>
 </provider>
    <provider class="com.opensymphony.user.provider.jdbc.JDBCProfileProvider">
  <property name="user.table">os_user</property>
  <property name="group.table">os_group</property>
  <property name="membership.table">os_membership</property>
  <property name="user.name" >username</property>
  <property name="user.password">passwordhash</property>
  <property name="group.name">groupname</property>
  <property name="membership.userName" >username</property>
  <property name="membership.groupName">groupname</property>
  <property name="datasource">java:jdbc/mySQL-shop</property>
 </provider>
 <authenticator class="com.opensymphony.user.authenticator.SmartAuthenticator" />
</opensymphony-user>

5.增加webapp/WEB-INF/classes/propertyset.xml 文件
<propertysets>
 <propertyset name="jdbc" class="com.opensymphony.module.propertyset.database.JDBCPropertySet">
  <arg name="table.name" value="os_propertyentry"/>
  <arg name="col.globalKey" value="GLOBAL_KEY"/>
  <arg name="col.itemKey" value="ITEM_KEY"/>
  <arg name="col.itemType" value="ITEM_TYPE"/>
  <arg name="col.string" value="STRING_VALUE"/>
  <arg name="col.date" value="DATE_VALUE"/>
  <arg name="col.data" value="DATA_VALUE"/>
  <arg name="col.float" value="FLOAT_VALUE"/>
  <arg name="col.number" value="NUMBER_VALUE"/>
  <arg name="datasource" value="java:jdbc/mySQL-shop"/>
  <arg name="" value=""/>
 </propertyset>
</propertysets>

到这里就配置文件就差不多了，剩下得就是将 webapp目录下得文件打包成 osworkflowExample.war 拷贝到jboss 得server/default/deploy目录下， 重新启动jboss
用http://127.0.0.1:8080/osworkflowExample 就可以访问例子程序了,
运行例子程序，先建立三个group :(foos,bazs,bars),再建立一个用户test,test属于foos,bazs,bars组
这样就可以启动工作流，执行工作流部骤了

在家弄了两个上午才搞成功这个东西，特别是osuer.xml,propertyset.xml这两个文件，因为家里不能上网，没有资料，只好用小聪反编译软件把oscore.jar,ospropertyset.jar
反编译，看源码才弄出这两个文件，这只是我学习osworkflow的开始，路还很长
