Hi!
I posted my previous message from the web client and it was corrupted. So
here is the full one:
get InvocationTargetException after the following:
return constructor.newInstance( kbase, conf, env );
in KnowledgeStoreServiceImpl.
I see that in return (T) constructorAccessor.newInstance(initargs) of
Constructor class it throws the InvocationTargetException.
The exception is null so I can't see what it the problem!
I call the code from this:
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);
I define the transaction manager in my spring beans like this:
<!-- Bitronix Transaction Manager embedded configuration -->
<bean id="xaDataSource"
class="bitronix.tm.resource.jdbc.PoolingDataSource"
init-method="init" destroy-method="close">
<property name="className"
value="bitronix.tm.resource.jdbc.lrc.LrcXADataSource" />
<property name="uniqueName" value="java/DS1" />
<property name="maxPoolSize" value="5" />
<property name="minPoolSize" value="0" />
<property name="allowLocalTransactions"
value="false" />
<property name="testQuery" value="SELECT 1 FROM
DUAL" />
<property name="driverProperties">
<props>
<prop key="user">username</prop>
<prop
key="password">username</prop>
<prop key="url">url</prop>
<prop
key="driverClassName">oracle.jdbc.OracleDriver</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,xaDataSource"
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 -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory"
ref="OnMediaSessionFactory"
/>
</bean>
I see that bitronix is up via the debugging messages. (2011-03-16
12:14:53,399 DEBUG ( PoolingDataSource.java:84) - building XA
pool for java/DS1 with 0 connection(s) etc..)
in persistence.xml I have:
<persistence-unit name="org.drools.persistence.jpa"
transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java/DS1</jta-data-source>

<properties>
<property name="hibernate.dialect"
value="org.hibernate.dialect.Oracle10gDialect" />
<property

<property name="hibernate.max_fetch_depth"

<property name="hibernate.show_sql"
value="true" />
<property
name="hibernate.connection.driver_class"

<property name="hibernate.jndi.class"

<property
name="hibernate.transaction.manager_lookup_class"
value="org.hibernate.transaction.BTMTransactionManagerLookup" />
</properties>
</persistence-unit>
What could cause the problem?
When I defined the btm with tomcat and not with spring - it worked fine.
(but I had context reloading problems). when I define it only with spring -
it get this weird exception.
Thanks!
