Dear all,
I have a BPM application based on JBoss + JBPM 3.2. I'd like to know if it's
possible to inject an Action Class to another Class using Spring.
Here's the case:
| <state name="TIMEOUT">
| <event type="node-enter">
| <action class="jbpm.action.ProcedureExecutor"/>
</event>
| <transition name="" to="P_CONF_MAN"></transition>
| </state>
|
When ProcedureExecutor is fired, then I'd like to use Spring to decide which
DAO class needs to be invoked
| public class ProcedureExecutor implements ActionHandler
| ......
| private String procedureName;
|
| public void execute(ExecutionContext arg0) throws Exception {
| this.procedureName = "MyProcedure";
|
| Resource res = new ClassPathResource("applicationContext.xml");
|
| BeanFactory factory = new XmlBeanFactory(res);
|
| // Here invoked DAO(ProcedureExecutor)
| BaseDAO bean1 = (BaseDAO)factory.getBean("BaseDAO");
|
|
| bean1.execute();
| }
|
I have configured my spring file so that an instance of ProcedureExecutor is
passed to DAO
| <bean id="ProcedureExecutor"
| class="jbpm.action.ProcedureExecutor">
| </bean>
|
|
| <bean id="BaseDAO"
| class="jbpm.dao.BaseDAO">
| <constructor-arg><ref bean="ProcedureExecutor"/></constructor-arg>
|
| </bean>
|
The problem is that when an instance of ProcedureExecutor is passed to DAO,
it's not passed the same instance of ProcedureExecutor I have in memory, so the
property "procedureName" is null.
I guess the problem is that ProcedureExecutor was instantiated by the container
and not by myself ?
Does anybody know if it's possible to use Spring to inject a JBPM Action class
?
Hope I was clear....
Thanks a lot
Francesco
