Hi!
I am working already for 3 days, trying to configure bitronix with spring
and drools.
I defined
1. persistence unit:
<persistence-unit name="org.drools.persistence.jpa" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>jdbc/DS1</jta-data-source>
<class>org.drools.persistence.info.SessionInfo</class>
<class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>
<class>org.drools.persistence.info.WorkItemInfo</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>
<property name="hibernate.dialect"
value="org.hibernate.dialect.Oracle10gDialect" />
<property name="hibernate.connection.autocommit"
value="false" />
<property name="hibernate.max_fetch_depth" value="3" />
<property name="hibernate.show_sql" value="true" />
<property
name="hibernate.current_session_context_class" value="jta" />
<property name="hibernate.connection.driver_class"
value="oracle.jdbc.xa.client.OracleXADataSource" />
<property name="hibernate.jndi.class"
value="bitronix.tm.jndi.BitronixInitialContextFactory"/>
<property
name="hibernate.transaction.manager_lookup_class"
value="org.hibernate.transaction.BTMTransactionManagerLookup" />
</properties>
</persistence-unit>
2. in my application context:
<!-- Bitronix Transaction Manager embedded configuration -->
<bean id="oracleDataSource"
class="bitronix.tm.resource.jdbc.PoolingDataSource"
init-method="init" destroy-method="close">
<property name="className"
value="oracle.jdbc.xa.client.OracleXADataSource" />
<property name="uniqueName" value="jdbc/DS1" />
<property name="maxPoolSize" value="5" />
<property name="allowLocalTransactions" value="true" />
<property name="testQuery" value="SELECT 1 FROM DUAL" />
<property name="driverProperties">
<props>
<prop key="user">myuser</prop>
<prop key="password">myuser</prop>
<prop key="URL">myurl</prop>
</props>
</property>
</bean>
<bean id="btmConfig" factory-method="getConfiguration"
class="bitronix.tm.TransactionManagerServices">
<property name="serverId" value="spring-btm" />
</bean>
<bean id="BitronixTransactionManager"
factory-method="getTransactionManager"
class="bitronix.tm.TransactionManagerServices"
depends-on="btmConfig"
destroy-method="shutdown" />
<bean id="JtaTransactionManager"
class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManager"
ref="BitronixTransactionManager" />
<property name="userTransaction"
ref="BitronixTransactionManager" />
</bean>
<!-- end of Bitronix Transaction Manager embedded configuration -->
3. and in the code:
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.drools.persistence.jpa");
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
env.set(EnvironmentName.GLOBALS, new MapGlobalResolver());
env.set(EnvironmentName.TRANSACTION_MANAGER,
TransactionManagerServices.getTransactionManager());
ksession =
JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null,
env);
However in the last code I get:
