l 第一部分用一系列的服务实现配置jbpm上下文。可能的配置选项被提及在特定的服务实现中提到了。
l 第二部分是所有的持久性映射的配置资源。这些资源引用可以被更新如果你想定制这些资源中的一个文件的话。通常，你可以生成一个在jbpm-3.x.jar中的缺少配置的一个拷贝然后把它放在你的类路径上的某处。然后你更新这个文件中的引用那么jbpm将使用你定制的配置文件。
l 第三部分是一些用于jbpm的零散配置。这些配置选项在特定主题的章节中被描述。
| public void deployProcessDefinition(ProcessDefinition processDefinition) {...} public List getTaskList() {...} public List getTaskList(String actorId) {...} public List getGroupTaskList(List actorIds) {...} public TaskInstance loadTaskInstance(long taskInstanceId) {...} public TaskInstance loadTaskInstanceForUpdate(long taskInstanceId) {...} public Token loadToken(long tokenId) {...} public Token loadTokenForUpdate(long tokenId) {...} public ProcessInstance loadProcessInstance(long processInstanceId) {...} public ProcessInstance loadProcessInstanceForUpdate(long processInstanceId) {...} public ProcessInstance newProcessInstance(String processDefinitionName) {...} public void save(ProcessInstance processInstance) {...} public void save(Token token) {...} public void save(TaskInstance taskInstance) {...} public void setRollbackOnly() {...} |
指定多个jbpm上下文中可能的，但是那样的话你就不得不确保每个jbpm上下文赋予了唯一的命名（name）属性。被命名的上下文能够被JbpmConfiguration.createContext(String name)方法检索。
服务元素指定服务的名称和那个服务的服务工厂。这个服务将只在它使用JbpmContext.getServices().getService(String name)方法进行请求时被创建。
6.1 配置工厂
|
...
<service name='persistence' factory='org.jbpm.persistence.db.DbPersistenceServiceFactory' /> |
| <service name="persistence">
<factory>
<bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory"> <field name="dataSourceJndiName"><string value="java:/myDataSource"/></field> <field name="isCurrentSessionEnabled"><true /></field> <field name="isTransactionEnabled"><false /></field> </bean>
</factory>
</service>

6.2 配置属性
6.3其他的配置文件
6.3.1 Hibernate cfg xml 文件
6.3.2 Hibernate 查询配置文件
这个文件包含hibernate的查询被使用在jBPM 的session 类org.jbpm.db.*Session中。
6.3.3节点类型配置文件
6.3.4 动作类型配置文件
6.3.5商务日历配置文件
6.3.6 变量映射配置文件
6.3.7 转换器配置文件
6.3.8 缺省模型配置文件
6.3.9 流程包解析配置文件
6.4 在JBoss 中的jBPM 调试日志
6.5 乐观并发异常日志
