JBPM-存储过程数据（PostgreSQL）

我正在尝试使用PostgreSQL存储JBPM流程数据（使用独立Java应用程序启动流程）。JBPM-5.1（在JBoss5.1上）。Postgresql-9.1。JDBC驱动程序（在应用程序的类路径中）-postgresql-9.1-901.jdbc4

我的persistence.xml（基于JBPM用户指南，第7.1.3章）是：

当我运行它时，最后一行给出了一个异常：

可能我需要执行或配置其他操作。。。但是我被卡住了：（

如果您试图在JBoss内部部署应用程序，那么应该在容器内创建数据源，而不是像在任何容器外运行的单元测试那样从源代码创建数据源。

---

如果jndi.properties不起作用（jvm找不到），只需在jvm中设置该属性即可 -Djava.naming.factory.initial=bitronix.tm.jndi.BitronixInitialContextFactory

---

请参阅。

您是如何运行应用程序的？JNDI错误表明您没有在提供JNDI环境的框架内运行应用程序，大多数应用程序服务器都会这样做，尽管像Tomcat这样的Web服务器不会这样做（不添加一些附加配置）。它是一个独立的Java类，具有main方法（嗯，我是jBPM新手，所以现在我只是在测试）。根据jBPM源代码发行版中提供的jBPM指南和jUnit测试，这应该足够了（或者我错过了一些东西，很可能是：（）。我还尝试添加了jndi.properies（我在运行的JBoss上部署了一个数据源），但它也不起作用。好的。我自己找到了解决方案，但我还不能发布答案。我会在可能的时候发布。也许有人可以使用它：）嗯，Hibernate正在通过JNDI寻找数据源，这似乎是原因，我想您需要调整配置，以便它使用自己的默认池连接提供程序和JDBC URL来代替它。@Ania您做了什么来解决它？

    PoolingDataSource ds = new PoolingDataSource();         
                ds.setDatabaseName("jbpm");
                ds.setUser("jbpmmanager");
                ds.setPassword("jbpm");     
                ds.setDataSourceName("jdbc/JbpmDS");
                ds.setServerName("localhost");
                ds.setPortNumber(5432);
                ds.setMaxConnections(3);            
                ds.initialize();
