jBPM 棄用jndi DataSource
昨天胡搞了一天，雖然弄好了jBPM的數據庫設置，但是經過昨晚回去查看Help 關于deployment的文檔和相關的源碼，終于弄出最簡單的方法。
Help Deployment中關于jbpm.properties
Following properties can be specified in the jbpm.properties configuration file
Table 5.2.
| Property |
Default Value |
Description |
| jbpm.session.factory.jndi.name |
|
if specified, the JbpmSessionFactory.getInstance() method will fetch the singleton instance from the given JNDI location. Otherwise a new JbpmSessionFactory will be created upon initialization of the singleton instance. |
源碼中的這個JbpmSessionFactory.java類中
public static JbpmSessionFactory getInstance() {
if (instance==null) {
// if there is a JNDI name configured
if (jndiName!=null) {
try {
// fetch the JbpmSessionFactory from JNDI
log.debug("fetching JbpmSessionFactory from '"+jndiName+"'");
InitialContext initialContext = new InitialContext();
Object o = initialContext.lookup(jndiName);
instance = (JbpmSessionFactory) PortableRemoteObject.narrow(o, JbpmSessionFactory.class);
} catch (Exception e) {
throw new RuntimeException("couldn't fetch JbpmSessionFactory from jndi '"+jndiName+"'");
}
} else { // else there is no JNDI name configured
// create a new default instance.
log.debug("building singleton JbpmSessionFactory");
instance = buildJbpmSessionFactory();
}
}
return instance;
}
可以看到只可以修改jbpm.properties文件就ok了。
現在行動！編輯jbpm\deploy\jbpm.sar中的jbpm.sar.cfg.jar文件
將JbpmSessionFactory修改如下
jbpm.scheduler.service.factory=org.jbpm.scheduler.impl.SchedulerServiceImpl
jbpm.task.instance.class=org.jbpm.taskmgmt.exe.TaskInstance
#jbpm.session.factory.jndi.name=java:/jbpm/JbpmSessionFactory
jbpm.hibernate.cfg.xml=jbpm.hibernate.cfg.xml
#jbpm.hibernate.properties=jbpm.hibernate.properties
因此jbpm.hibernate.properties也可以刪除了，之后修改jbpm.hibernate.cfg.xml和另外一個文件的數據庫配置，另外弄個數據庫的driver就ok啦！！！
