The EJB is part of a .ear file , using the MySQL database. I have defined a persistence unit in persistence.xml within the META-INF folder and also placed the corresponding JBPMorm.xml in the META-INF folder. The datasaource is deployed in the deploy folder of JBOss 5.1 persistence .xml <?xml version="1.0" encoding="UTF-8"?> <persistence xmlns=" http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence"      xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance"      xsi:schemaLocation=" http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"       version="1.0">                <persistence-unit name="SecureALLPU" transaction-type="JTA">               <jta-data-source>java:/SecureAll</jta-data-source>               <properties>                               <property name="hibernate.format_sql" value="true"/>                               <property name="dialect" value="org.hibernate.dialect.OracleDialect"/>                               <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>                     </properties>       </persistence-unit>   <persistence-unit name="org.jbpm.persistence.jpa.secureall" transaction-type="JTA">     <provider>org.hibernate.ejb.HibernatePersistence</provider>        <jta-data-source>java:jdbc/SecureAlljbpmDatasource</jta-data-source>               <mapping-file>META-INF/JBPMorm.xml</mapping-file>        <class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>     <class>org.drools.persistence.info.SessionInfo</class>     <class>org.drools.persistence.info.WorkItemInfo</class>     <properties>          <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>               <property name="hibernate.max_fetch_depth" value="3"/>       <property name="hibernate.hbm2ddl.auto" value="create" />       <property name="hibernate.show_sql" value="false" />       <!-- <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" /> -->       <property name="hibernate.transaction.manager_lookup_class"                 value="org.hibernate.transaction.BTMTransactionManagerLookup"/>     </properties>          </persistence-unit>    </persistence> JBPMORM.XML <?xml version="1.0" encoding="UTF-8"?> <entity-mappings xmlns=" http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm"                xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance"                xsi:schemaLocation=" http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm orm_1_0.xsd"                version="1.0">        <named-query name="ProcessInstancesWaitingForEvent">           <query> select     processInstanceInfo.processInstanceId from     ProcessInstanceInfo processInstanceInfo where     :type in elements(processInstanceInfo.eventTypes)           </query>       </named-query> </entity-mappings> Datasource: <?xml version="1.0" encoding="UTF-8"?> <datasources>           <local-tx-datasource>     <jndi-name>jdbc/SecureAlljbpmDatasource</jndi-name>     <connection-url>jdbc:mysql://localhost:3306/JBPM?useUnicode=true&amp;characterEncoding=UTF-8</connection-url>     <!--<connection-url>jdbc:h2:mem:mydb</connection-url>-->     <driver-class>com.mysql.jdbc.Driver</driver-class>     <user-name>root</user-name>     <password></password>           <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>            <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>   </local-tx-datasource> </datasources> When i deploy my .ear file App Server is able to recognise the datasource, persistence unit for jbpm datasource from persistence.xml and corresponding jbpmorm.xml. However I get the exception : javax.persistence.PersistenceException: [PersistenceUnit: org.jbpm.persistence.jpa.secureall] Unable to build EntityManagerFactory On looking into the details for it I understand that EntityManagerFactory needs to be loaded by the name: org.jbpm.persistence.jpa.secureall Something like: | | | EntityManagerFactory emf = | | | |     Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa.secureall" ); | | | | Environment env = KnowledgeBaseFactory.newEnvironment(); | | | | env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf ); | | | | env.set(EnvironmentName.GLOBALS, new MapGlobalResolver()); | However I am not sure how do i define EntityManagerFactory by that name such that it gets loaded by that name during deployment rather than during run time. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/619510#619510] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
