JBoss JBPM 实践系列（一）--- 安装配置（Tomcat 6.0 + MySQL 5.1）

JBoss JBPM 实践系列（一）--- 安装配置（Tomcat 6.0 + MySQL 5.1）

 

       jBPM，全称是Java Business Process Management，是一种基于J2EE的轻量级工作流管理系统。jBPM是公开源代码项目，遵循Apache License。jBPM在2004年10月18日，发布了2.0版本，并在同一天加入了JBoss，成为了JBoss企业中间件平台的一个组成部分，它的名称也改成JBoss jBPM。

 

       jBPM有两大特色，使他成为市场的一大两点。其中最大的特色就是它的业务逻辑定义没有采用目前的一些规范，如WfMC´s XPDL, BPML, ebXML, BPEL4WS等，而是它自己定义的JBoss jBPM Process definition language (jPdl)。jPdl把一个业务逻辑流程看作是一个UML状态图，如果你不熟悉UML状态图，那初学计算机语言的流程图应该熟悉吧，表达的方式和意思大同小异。jPdl详细定义了这个状态图的每个部分，如起始、结束状态，状态之间的转换等；其另一大特色就是集成Hibernate,确切的说是绑定，使用Hibernate来管理数据库，这样jBPM只专注于他的业务流程控制。

 

       从上面可以看出，jBPM是一个业务流程管理引擎，是一个工作流引擎。除此之外，它同时实现了对jPDL和对BPEL的支持。它整合了Hibernate技术处理数据库，创建了一系列的数据库表，持久化工作流引擎所需的状态。因此，jBPM支持所有Hibernate支持的数据库，能够把Java对象持久化到数据库中，把Hibernate支持的Java类的对象保存到数据库中！

     

       你完全可以像用 Java 的类库一样使用JBoss jBPM，而且通过配置JBoss jBPM也可以被部署在其它J2EE应用服务器上和任何数据库上。

 

       在本文中，我们首先来创建我们的JBoss jBPM运行开发环境。在开始之前，请准备一下软件产品：

·JDK 1.5 或者更高版本, 这里使用JDK 6u10b

·Apache Tomcat 5.5.x或更高版本，这里使用Tomcat 6.0.16

·MySQL 5.1 ,也可以选择其它Hiberante 支持的数据库，没有太大差别，这里使用MySQL 5.1

·Apache Ant 1.7.0

·JBPM-3.2.3

·Eclipse Europa（Eclipse V3.3） for JavaEE Developers或更高, 这里使用Eclipse V3.4

 

说明：JBoss jBPM的发布包中已经配置好了一套服务环境，是基于JBoss的。因为我们习惯了Tomcat 的小巧灵活，而且我们也不希望jBPM依赖JBoss。

 

1. 下载安装JDK，Tomcat, Ant, MySQL, 并设置相应的环境变量

 此步骤不再熬述，具体请查阅官方文档

  Jdk：http://java.sun.com/

  Ant：http://ant.apache.org/

Tomcat：http://tomcat.apache.org/

 Eclipse：http://www.eclipse.org/

 

 2. 下载JBoss jBPM

JBoss jBPM 官方（http://www.jboss.org/jbossjbpm/）当前发布的版本为 3.2.3, 只需要下载jPDL Suite,下载后得到jbpm-jpdl-suite-3.2.3.zip，这个套件包含了所有的内容和资源，包括eclipse插件，示例，和流程管理控制应用。

解压jbpm-jpdl-suite-3.2.3.zip，这里解压后得到D:\jbpm-jpdl-3.2.3，其主要目录结构如下：

D:\jbpm-jpdl-3.2.3

|--- db    这里都是些sql定义和数据文件，如果改用其它数据库，可以使用这些资源来创建，服务还是很周到的。顺便

|             罗嗦一句，jBPM 默认使用的是内存数据库 hsqldb ，这个数据库还没研究过（嘿嘿---）

|

|--- deploy  用来部署你的应用的包和资源

|

|--- designer  这里是Eclipse插件，这样你就可以在图形界面来定义你的业务流程，骨灰级人物没他也能过日子

|

|--- doc  这里是jBPM相关组件的API 文档

|

|--- examples  这里是些学习的例子

|

|--- lib  jBPM 的类库

|

|--- server  这里有一个JBoss 服务器，并且包含了本JBoss jBPM引擎，还部署了websale例子

|

|--- src  这里是JBoss jBPM的源代码

 

 

      3. 配置数据库

      jBPM需要把初始化数据和工作流定义存储到数据库中，它定义了一套数据结构来存储这些数据，这也是该容器本身的特点。

 

      在mysql 中创建一个数据库 jbpm ,(create database jbpm;)，并创建用户jbossjbpm（密码：jbossjbpm）

      说明：如果你嫌麻烦可以使用root账号和其密码，不过下面的设置请做相应的更改

 

      在D:\jbpm-jpdl-3.2.3\db 找到jbpm.jpdl.mysql.sql, 该文件必须修改一下，以符合MySQL的语法结构。具体就是在每条语句的末尾增加一个分号";"你可以借助 UltrEdit, EditPlus等工具来做这些事情（注意替换时要注意匹配大小写，有写表的字段中包含CREATE字符）,如果是第一次创建这些数据库表，要删除create语句上面的alter和drop（这些表还都不存在）。

 

 

      4. 准备jBPM包

      这是个jbpm-jpdl流程管理控制台，就像Tomcat有个单独的Administrator应用用来管理配置和部署一样的东东。有了他你可以在图形界面来操作控制你的应用。

 

      打开命令行控制台，切换到D:\jbpm-jpdl-3.2.3\deploy 目录，执行以下命令：

      ant customize.console.for.tomcat

  

    注意：请确保你的ant安装配置妥当，可以在命令行输入：ant -version 来检测ant 是否正确安装。命令执行后能看到ant的版本信息即OK

 

    ant customize.console.for.tomcat 执行成功后，会在D:\jbpm-jpdl-3.2.3\deploy 目录下生成customized和target目录，其中customized目录下的jbpm-console.war即是我们想要的war包。

       我们需要修改jbpm-console.war/WEB-INF/classes/hibernate.cfg.xml 文件，以适应我们的资源属性的需要。修改后的结果如下：

<hibernate-configuration>
  <session-factory>

    <!-- hibernate dialect -->
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>

    <!-- JDBC connection properties (begin) -->
    <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">jbossjbpm</property>
    <property name="hibernate.connection.password">jbossjbpm</property>
     <!-- JDBC connection properties (end) -->
    
    <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
    
    <!-- DataSource properties (begin) ==
    <property name="hibernate.connection.datasource">java:/JbpmDS</property>
    == DataSource properties (end) -->
    <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
...	

 

       这里就是启用了 更换了默认的数据属性，JDBC connection properties ，还有自己定义的数据名字和帐号，另外需要注意的是用

<property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>

 

代替JTATransactionFactory和CMTTransactionFactory，想用JTATransactionFactory或CMTTransactionFactory配置也可以，不过还没有研究过，有知道的朋友可以一起学习一下。

 

   

       拷贝jboss-j2ee.jar包至jbpm-console.war/WEB-INF/lib 。发布包下（D:\jbpm-jpdl-3.2.3）很多地方都有这个包你可以找一下，比如 D:\jbpm-jpdl-3.2.3\server\client。

       这里主要是用到了Java Transaction Architecture, 所以你可以用J2EE中的jta.jar包还替换jboss-j2ee.jar。jta相关信息请参考：http://java.sun.com/javaee/technologies/jta/index.jsp

 

        拷贝commons-collections.jar 包至jbpm-console.war/WEB-INF/lib  。发布包下（D:\jbpm-jpdl-3.2.3）好几处都有这个包，比如 D:\jbpm-jpdl-3.2.3\server\server\jbpm\lib 。这个包是Apache Commons包，到处都找的的到。

 

        拷贝jsf-api.jar和jsf-impl.jar包至jbpm-console.war/WEB-INF/lib ，你可以在D:\jbpm-jpdl-3.2.3\server\server\jbpm\deploy\jboss-web.deployer\jsf-libs种找到这两个包。

        说明：因为jbpm-console是一个jsf应用，没这两个包，你访问时会报404或505错误。

 

        拷贝MySQL JDBC驱动程序包至%CATALINA_HOME%/lib （Tomcat 6）或%CATALINA_HOME%/common/lib（Tomcat 5.5）

       

 

        拷贝修改后的jbpm-console至%CATALINA_HOME%/webapps

 

        这样jBPM基本上配置完成，但是我们还不能访问他，还需要配置安全访问控制和初始的用户数据

 

 

        5. 配置Tomcat 安全域

        方法一：在%CATALINA_HOME%/conf/Catalina/localhost 创建一个jbpm-console.xml 文件，内容如下：

<Context>
<Realm  className="org.apache.catalina.realm.JDBCRealm" 
	driverName="com.mysql.jdbc.Driver"
	connectionURL="jdbc:mysql://localhost:3306/jbpm"
	connectionName="jbossjbpm" 
	connectionPassword="jbossjbpm"
	userTable="JBPM_ID_USER u, JBPM_ID_MEMBERSHIP m, JBPM_ID_GROUP g" 
	userNameCol="g.TYPE_ = 'security-role' AND m.GROUP_ = g.ID_ AND m.USER_ = u.ID_ AND u.NAME_" 
	userCredCol="DISTINCT u.PASSWORD_"
	userRoleTable="JBPM_ID_USER u, JBPM_ID_MEMBERSHIP m, JBPM_ID_GROUP g" 
	roleNameCol="g.NAME_" />
</Context>

 

         方法二：修改 %CATALINA_HOME%/conf/tomcat-users.xml文件来设置安全域。为了不和tomcat已有的用户冲突,这里把 tomcat以前的登陆帐号username="admin" 修改为username="tadmin"，修改后的文件如下：

 

<?xml version='1.0' encoding='utf-8'?>

<tomcat-users>

  <role rolename="user"/>

  <role rolename="administrator"/>

  <role rolename="manager"/>

  <role rolename="sales"/>

  <role rolename="hr"/>

  <role rolename="admin"/>

  <role rolename="participant"/>

  <user username="user" password="user" roles="user,sales"/>

  <user username="shipper" password="shipper" roles="user,hr"/>

  <user username="manager" password="manager" roles="admin,hr,manager,user,sales"/>

  <user username="tadmin" password="" roles="admin,manager"/>
  <user username="admin" password="admin" roles="admin,user,hr"/>
</tomcat-users>

 

         6. 初始化数据

         在MySQL jbpm数据库中插入以下数据

INSERT INTO JBPM_ID_GROUP VALUES(1,'G','sales','organisation',NULL);

INSERT INTO JBPM_ID_GROUP VALUES(2,'G','admin','security-role',NULL);

INSERT INTO JBPM_ID_GROUP VALUES(3,'G','user','security-role',NULL);

INSERT INTO JBPM_ID_GROUP VALUES(4,'G','hr','organisation',NULL);

INSERT INTO JBPM_ID_GROUP VALUES(5,'G','manager','security-role',NULL);

INSERT INTO JBPM_ID_USER VALUES(1,'U','user','user@sample.domain','user');

INSERT INTO JBPM_ID_USER VALUES(2,'U','manager','manager@sample.domain','manager');

INSERT INTO JBPM_ID_USER VALUES(3,'U','admin','admin@sample.domain','admin');

INSERT INTO JBPM_ID_USER VALUES(4,'U','shipper','shipper@sample.domain','shipper');

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(1,'M',NULL,NULL,2,4);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(2,'M',NULL,NULL,3,4);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(3,'M',NULL,NULL,4,4);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(4,'M',NULL,NULL,4,3);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(5,'M',NULL,NULL,1,3);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(6,'M',NULL,NULL,2,3);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(7,'M',NULL,NULL,3,3);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(8,'M',NULL,NULL,3,2);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(9,'M',NULL,NULL,2,2);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(10,'M',NULL,NULL,2,5);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(11,'M',NULL,'boss',2,1);

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(12,'M',NULL,NULL,1,1);

 

      7. 启动Tomcat 服务，查看控制台的日志，排除错误，数据库错误和支持库不完整都可能导致错误。

      在浏览器中输入：http://localhost:8080/jbpm 能正常访问说明部署成功，你可以用页面上列出的用户和账号登陆进去体验一下。

好象配置中没有涉及到jndi的配置,我的tomcat 6.0 怎么会抛出这问题,就运行不过去了

这个不用管他，不是错误。如果没有其他问题，你就可以在浏览器中访问看看

我用的环境几乎和你一样可是不知道怎么老出这个错误。您能帮我解答一下么？

请你先确定一下，你的classpath路径下是否有hibernate3.jar 和 mysql-connector-java.jar(%CATALINA_HOME%\lib 下)，仔细检查一下自己是否疏忽了哪个环节，我这里屡试不爽

在你的log中有下面这行：
信息: Using datasource: java:comp/env/jdbc/JbpmDataSource
2008-7-20 14:17:42 org.hibernate.dialect.Dialect <init>


说明你的hibernate.cfg.xml没有按文中描述的方法去做。

    ……
    <!-- DataSource properties (begin) ===
    <property name="hibernate.connection.datasource">java:comp/env/jdbc/JbpmDataSource</property>
    === DataSource properties (end) -->
    ……

JbpmDataSource 是被注释了的

谢谢阿！我知道了。已经成功了。
原来这句话得注释掉

适用工作流有什么好处？ 它位于哪一层？ 既然工作流是业务流程管理引擎，那就是位于业务层了吗？  该如何把jbpm集成到web应用系统架构中呢？ 

我可以给你一点建议，jBPM是和 Herbinate 绑定的，如何你做过 ssh (Struts + Spring + Hibernate) 我想你会比较容易找到感觉。网上已经有很多例子了，你可以参考一下。
有空我再整一篇集成的例子出来吧，现在项目紧张，无暇分身呐！

hi,又是我

1.hibernate配置
<hibernate-configuration>
  <session-factory>

    <!-- hibernate dialect -->
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>

    <!-- JDBC connection properties (begin) === -->
       <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">jbpm</property>
    <property name="hibernate.connection.password">jbpm</property>
   <!-- ==== JDBC connection properties (end) -->
   
    <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
    <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property> 

其他没改动过

2.安全域的配置 是copy你的。


现在问题是，我跑jbpm-jpdl-3.2版本的，就一登录出现
Access to the requested resource has been denied

description Access to the specified resource (Access to the requested resource has been denied) has been forbidden.

如果跑jbpm-jpdl-3.2.2版本，就是404错误。如下:
message /jbpm-console/search/tasks.jsf

description The requested resource (/jbpm-console/search/tasks.jsf) is not available.

但我jsf的两个jar包都加了。

郁闷了，望你指导，指导。
