我创建了几个流程，但它们都只是保存在内存中的，关闭JBOSS再次启动就看不到我创建的流程的，而且我创建的时候直接到数据库去看JBPM的表，也没看到任何数据生成，要做什么特别的设置才会生效吗？我用的是MYSQL数据库。

你至少要把配置文件和关键的代码贴出来吗，否则这个问题很难回答

流程定义文件

这是创建流程的方法，方法里的代码作用是向我定义的“订单”表中新建一条订单记录
按理来说流程一旦创建后就会持久化到数据库中的不是吗？

@CreateProcess(definition="process")
public void CreateProcess(){
    MyOrder od = new MyOrder();
    od.setState("start");
    od.setName(credentials.getUsername());
    entityManager.persist(od);
    orderid = od.getId();
    act = credentials.getUsername();
}

你的数据源呢

这是数据源

<?xml version="1.0" encoding="UTF-8"?>

删掉---》

        <property name="hibernate.connection.password">123456</property>

加入
<property name="connection.datasource">java:/BPMDatasource</property>

照你说的加上
<property name="connection.datasource">java:/BPMDatasource</property>
然后再删除
        <!-- <property name="hibernate.connection.driver_class">org.gjt.mm.mysql.Driver</property>
        <property name="hibernate.connection.password">123456</property>

这几个，就可以了，十分谢谢楼上的哥们
