参考博文：http://blog.csdn.net/dcl8261425/article/details/6575797
首先需要安装JBPM5和MYSQL。。。。

一、修改JBPM持久化相关配置文件
1、jbpm-installer/db/hibernate.cfg.xml
注释部分为原h2数据库的配置，下同。

<hibernate-configuration>

    <session-factory>

        <!-- Database connection settings -->
        <!--<property name="connection.driver_class">org.h2.Driver</property>-->
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <!--<property name="connection.url">jdbc:h2:tcp://localhost/~/test</property>-->
        <property name="connection.url">jdbc:mysql://localhost:3306/jbpm?useUnicode=true&characterEncoding=UTF-8</property>
        <!--property name="connection.url">jdbc:h2:file:/NotBackedUp/data/mydb</property-->
        <property name="connection.username">root</property>
        <property name="connection.password">root</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- SQL dialect -->
        <!--<property name="dialect">org.hibernate.dialect.H2Dialect</property>-->
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">false</property>

        <!-- Drop and re-create the database schema on startup? -->
        <property name="hbm2ddl.auto">create</property>

        <mapping resource="AuditLog.hbm.xml"/>

    </session-factory>

</hibernate-configuration>

2.jbpm-installer/db/persistence.xml
jta-data-source那一项匹配的是testDS1-ds.xml中jndi-name,自行修改

<persistence-unit name="org.drools.persistence.jpa" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>java:jdbc/jbpmDatasource</jta-data-source>        
    <class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>
    <class>org.drools.persistence.info.SessionInfo</class>
    <class>org.drools.persistence.info.WorkItemInfo</class>
<!--    <properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>	        
      <property name="hibernate.max_fetch_depth" value="3"/>
      <property name="hibernate.hbm2ddl.auto" value="create" />
      <property name="hibernate.show_sql" value="false" />	
      <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" />
    </properties>   --> 
    <properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
      <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
      <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/jbpm?useUnicode=true&characterEncoding=UTF-8" />
      <property name="hibernate.connection.username" value="root"/>
      <property name="hibernate.connection.password" value="root"/>
      <property name="hibernate.connection.autocommit" value="true" />
      <property name="hibernate.max_fetch_depth" value="3"/>
      <property name="hibernate.hbm2ddl.auto" value="create" />
      <property name="hibernate.show_sql" value="false" />
    </properties>    
  </persistence-unit>

3.jbpm-installer/db/testDS1-ds.xml

<datasources>
<!--  <local-tx-datasource>
    <jndi-name>jdbc/testDS1</jndi-name>
    <connection-url>jdbc:h2:tcp://localhost/~/test</connection-url>
    --><!--connection-url>jdbc:h2:mem:mydb</connection-url--><!--
    <driver-class>org.h2.jdbcx.JdbcDataSource</driver-class>
    <user-name>sa</user-name>
    <password></password>
  </local-tx-datasource>-->
   <jndi-name>jdbc/jbpmDatasource</jndi-name>
    <connection-url>jdbc:mysql://localhost:3306/jbpm?useUnicode=true&characterEncoding=UTF-8</connection-url>
    <!--connection-url>jdbc:h2:mem:mydb</connection-url-->
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <user-name>root</user-name>
    <password>root</password>
</datasources>

4.jbpm-installer/runtime/jbpm-bam.jar/hibernate.cfg.xml

<hibernate-configuration>

    <session-factory>

        <!-- Database connection settings -->
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/jbpm?useUnicode=true&characterEncoding=UTF-8</property>
        <!--property name="connection.url">jdbc:h2:file:/NotBackedUp/data/mydb</property-->
        <property name="connection.username">root</property>
        <property name="connection.password">root</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

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

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">false</property>

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">create</property>

        <mapping resource="AuditLog.hbm.xml"/>

    </session-factory>

</hibernate-configuration>

5.jbpm-installer/runtime/jbpm-human-task-{version}.jar/persistence.xml

<properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
      <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
      <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/jbpm?useUnicode=true&characterEncoding=UTF-8" />
      <property name="hibernate.connection.username" value="root"/>
      <property name="hibernate.connection.password" value="root"/>
      <property name="hibernate.connection.autocommit" value="true" />
      <property name="hibernate.max_fetch_depth" value="3"/>
      <property name="hibernate.hbm2ddl.auto" value="create" />
      <property name="hibernate.show_sql" value="false" />
    </properties>

二、相关jar包
mysql驱动包放在jbpm-installer/db/driver中
下载slf4j相关包，http://www.slf4j.org/download.html
下载btm-1.3.2.jar


三、编写TaskServer.java
需要导入JAR包：btm-1.3.2.jar、slf4j-jdk14-1.6.2.jar、mysql驱动包
标注的些地方换成自己相关的就行了

public static final void main(String[] args) {
		
		try {
			
			PoolingDataSource  ds1 = new PoolingDataSource();
		        ds1.setUniqueName( "jdbc/jbpmDatasource" );//这里
		        ds1.setClassName( "com.mysql.jdbc.jdbc2.optional.MysqlXADataSource" );
		        
		        ds1.setMaxPoolSize( 3 );
		        ds1.setAllowLocalTransactions( true );
                       //下面数据库相关 
                        ds1.getDriverProperties().put( "user",
		                                       "root" );
		        ds1.getDriverProperties().put( "password",
		                                       "root" );
		        ds1.getDriverProperties().put( "URL",
		                                     "jdbc:mysql://localhost:3306/jbpm?useUnicode=true&characterEncoding=UTF-8" );
          
	     
	                ds1.init();	
	      			
			EntityManagerFactory emfTask = Persistence.createEntityManagerFactory( "org.jbpm.task" );
			TaskService taskService = new TaskService(emfTask, SystemEventListenerFactory.getSystemEventListener());
			
			
			
			/*
	         * Add the required users 
	         */
	        TaskServiceSession taskSession = taskService.createSession();   
	        taskSession.addUser(new User("Administrator"));
	        taskSession.addUser(new User("krisv")); 
	        taskSession.addUser(new User("john")); 
	        taskSession.addUser(new User("mary")); 
	        
	        /* Start Mina server for HT*/
	        MinaTaskServer server = new MinaTaskServer(taskService);
	        Thread thread = new Thread(server);
	        thread.start();
	        System.out.println("Server started ..."); 
	       
		
		} catch (Throwable t) {
			t.printStackTrace();
		}
	}

好了，剩下的启动TaskServer然后运行下sample中的evaluation试试，完成human task中的任务，没有出错就一切OK了
