[jboss-user] [jBPM] - Jbpm and openJPA

malabalu [https://community.jboss.org/people/malabalu] created the discussion "Jbpm and openJPA" To view the discussion, visit: https://community.jboss.org/message/724692#724692 -------------------------------------------------------------- We are trying to use openJPA fo rpersistence along with Spring . We ran into coupel of issues with SessionInfo, WorkItemInfo classes and a query in JBPorm.xml file. We had to change the Id generation for the above 2 classes into Sequence as below strategy = GenerationType.SEQUENCE, generator="sessionInfoIdSeq"...It was originally havifn AUTO but with geenrator as sessionInfoIdSeq...which prevented htese classes from enhanced. Also once cross these problems, I ran into a query defined in JBPOrm.xml with ":"  in it which is not suitable for JPA  and also a field eventype reference which it complains that not found .So I had to include a orm.xml in my classpath and override the query as below. <named-native-query name="ProcessInstancesWaitingForEvent" result-set-mapping="ProcessInstancesWaitingForEvent.mapping">     <query>     select distinct       p.InstanceId     from       ProcessInstanceInfo p     join       EventTypes e on p.InstanceId=e.InstanceId     </query> </named-native-query> Did anybody come across similar problems.Are my solutions right? Also finally I am running into a problem if I include the plugin in my pom.xml to enhance, it complains as below MetaDataFactory could not be configured (conf.newMetaDataFactoryInstance( ) returned null). This might mean that no configuration properties were found. E nsure that you have a META-INF/persistence.xml file, that it is available in you r classpath, or that the properties file you are using for configuration is avai lable. If you are using Ant, please see the <properties> or <propertiesFile> att ributes of the task's nested <config> element. This can also occur if your OpenJ PA distribution jars are corrupt, or if your security policy is overly strict. Any help will be appreciated. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/724692#724692] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
