[jboss-jira] [JBoss JIRA] Commented: (JBPM-945) Miss MailAction hibernate mapping file!

Miss MailAction hibernate mapping file! --------------------------------------- Key: JBPM-945 URL: http://jira.jboss.com/jira/browse/JBPM-945 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2 Environment: Windows XP SP2 Java JDK 1.5.0_10 Eclipse 3.2.1 Reporter: David Chan Assigned To: Tom Baeyens A process definition contains a node with type 'mail' like below: <?xml version="1.0" encoding="UTF-8"?> <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="mail"> <start-state name="start"> <transition name="a" to="task1"> <mail name="starter" actors="ws" subject="TT" text="NN"></mail> </transition> </start-state> <end-state name="end1"></end-state> <task-node name="task1"> <task name="task1"></task> <transition name="b" to="end1"></transition> </task-node> </process-definition> when I use JBPMContext to store the definition into DB, an exception will be thrown: aused by: org.hibernate.HibernateException: instance not of expected entity type: org.jbpm.graph.action.MailAction is not a: org.jbpm.graph.def.Action It's very clear that Hibernate can't know how to persist the class 'org.jbpm.graph.action.MailAction', in other words, there's no mapping file against to this class. So I created this file 'MailAction.hbm.xml', the content is very simple: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping default-access="field"> <subclass name="org.jbpm.graph.action.MailAction" extends="org.jbpm.graph.def.Action" discriminator-value="M"/> </hibernate-mapping> open the Hibernate configuration file and insert the mapping entry of MailAction. ..... <mapping resource="org/jbpm/graph/action/MailAction.hbm.xml"/> ..... now run the process again, there's no problem!
