I am trying to use Oracle AQ supporting XA transaction since i have other datasource like Active MQ and DB involved in the transaction. When i tried to post to oracle aq queue1. it is failing with a NullPointerException while getting the XAconnection from the datasource.
I am using oracle ojdbc6,aqapi.jar of 11.2 version
Snippet of my camel blueprint with my bean defintion is given below

I think i got what the issue is. The aqapi.jar that i am using from oracle 11.2 client has got the bug. The class AqjmsGeneralDBConnection is not initializing the m_dbConn object for the QAConnection (constructor with XAConnection as argument) and trying to access the getURL() on the m_dbConn object which is null. I tried using the aqapi13.jar from 10.2.0 version and it works
AQjmsGeneralDBConnection(AQjmsDBConnMgr paramAQjmsDBConnMgr, Connection paramConnection, boolean paramBoolean1, boolean paramBoolean2)
throws JMSException
{
this.m_connMgr = paramAQjmsDBConnMgr;
this.m_dbConn = paramConnection;
this.m_isExternal = paramBoolean1;

I have a spring batch application that uses Azure SQL server, it runs without any issues and updates the Database for a most part however I am getting the following error occasionally
what does it mean? how to handle this?
Note: this is a long running job executes for more than 2hrs. The above error reported after ~1.45hrs.
I am reading the data from CSV file using FlatfileReader & writing into Azure SQL Server using ItemWriter as mentioned below
public class StoreWriter implements ItemWriter<List<Store>> {
Logger logger = Logger.getLogger(StoreWriter.class);
private HibernateItemWriter<Store> hibernateItemWriter;
public StoreWriter(HibernateItemWriter<Store> hibernateItemWriter) {
this.hibernateItemWriter = hibernateItemWriter;
}
#Override
public void write(List<? extends List<Store>> items) throws Exception {
for (List<Store> Store : items) {
hibernateItemWriter.write(Store);
}
logger.info(String.format("Store Processing Completed %s", new LocalDateTime()));
}
}
Below is my Hibernate configuration

Spring and hibernate are both new tools for me and I struggle a bit using both at the same time.

}
persistence.xml :
<persistence-unit name="SUPERVISION-1.0">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>supervision.dao.SupervisionDbObject</class>
</persistence-unit>
Using JDBC, my DataSource can be instanciated and is fully working but using Hibernate and the entityManager, i only get an error :
Bean property 'entityManager' is not writable or has an invalid setter method.
I have tried to use the EntityManagerFactory object instead but the same error occurs.
Can someone help me out ?
The addition of the <context:annotation-config/> fixed my issue thanks to M. Deinum's answer.
If this can help someone else, I also had an issue with an import, I was importing
org.hibernate.annotations.Entity instead of javax.persistence.Entity.

I have a very simple requirement which has turned complicated and I have spent a day on it without any luck. I have a properties file called jdbc.properties which has the DB connection details. I need to create a datasource connection with the values from the property file. The property value is not being passed right now, leading to DB connectivity error messages. If I hardcode the property values in the bean, it works. My spring config file myBatis.DataSource.config.xml looks like this.

The value for ${env} is passed as a system property to the class. The code for the class is as below:
import org.apache.ibatis.session.ExecutorType;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.springframework.context.ApplicationContext;

public void testSelectQuery(){
String resource = "oneValidation-config.xml";
SqlSession session = null;
try {
ApplicationContext context = new ClassPathXmlApplicationContext("myBatis.DataSource.config.xml");
SqlSessionFactory sqlSessionFactory = (SqlSessionFactory)context.getBean("sqlSessionFactory");
session = sqlSessionFactory.openSession(ExecutorType.BATCH);
System.out.println("Test" +
session.selectOne("com.automation.config.PostingMapper.
countByExample",null));
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally {
if(session != null)
session.close();
}
}
}
The error I am getting is as shown below and is sue to the fact that the ${DBUSER}, ${DBPASSWORD} fields are not being retrieved from the property file jdbc.properties:
org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause:
org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC
Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot
create PoolableConnectionFactory (JZ00L: Login failed. Examine the SQLWarnings chained
to this exception for the reason(s).)
I ran accross this as well. In the mybatis documentation here I found why this happens.
From the source: "NOTE sqlSessionFactoryBean and sqlSessionTemplateBean properties were the only option available up to MyBatis-Spring 1.0.2 but given that the MapperScannerConfigurer runs earlier in the startup process that PropertyPlaceholderConfigurer there were frequent errors. For that purpose that properties have been deprecated and the new properties sqlSessionFactoryBeanName and sqlSessionTemplateBeanName are recommended."
Try changing your MapperScannerConfigurer bean from
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactory" ref="sqlSessionFactory" />
<property name="basePackage" value="com.automation.config" />
</bean>
to
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
<property name="basePackage" value="com.automation.config" />
</bean>
Try this:
<property name="locations" value="classpath:/yourFolderName/jdbc.properties"/>
I wish to execute few insert queries within a transaction block where if there is any error all the inserts will be rolled back.
I am using MySQL database and Spring TransactionManager for this.
Also the table type is InnoDB
I have done my configuration by following the steps mentioned here.
Following is my code (for now only one query)
TransactionDefinition def = new DefaultTransactionDefinition();
TransactionStatus status = null;
status = transactionManager.getTransaction(def);
jdbcTemplate.execute(sqlInsertQuery);
transactionManager.rollback(status);

This code works perfectly fine and the record gets inserted.
But the rollback doesnt work! It executes the rollback statement without any error but to no effect.
Can anyone guide me where am I going wrong?
It appears that the issues is your datasource is not set to have autocommit off.
<property name="defaultAutoCommit" value="false"/>
Give that a try. I have never used the TransactionManager outside of a proxy so I am not sure if there any other gotchas using it directly like this, but I would recommend you look at either AOP transactions or the convience AOP proxy annotation #Transactional just because it is more common.
EDIT:
I was finally able to resolve this by doing the following:
dmlDataSource.setDefaultAutoCommit(false); //set autocommit to false explicitly.
Exception ex = (Exception)transactionTemplate.execute(new TransactionCallback() {
public Object doInTransaction(TransactionStatus ts) {
try {
dmlJdbcTemplate.execute(sqlInsertQuery);
ts.setRollbackOnly();
dmlDataSource.setDefaultAutoCommit(true); // set autocommit back to true
return null;
} catch (Exception e) {
ts.setRollbackOnly();
LOGGER.error(e);
dmlDataSource.setDefaultAutoCommit(true); // set autocommit back to true
return e;
}
}
});
I am not using the transaction manager now. Using the trasactionTemplate and doing the following:
Exception ex = (Exception)transactionTemplate.execute(new TransactionCallback() {
public Object doInTransaction(TransactionStatus ts) {
try {
dmlJdbcTemplate.execute(sqlInsertQuery);
ts.setRollbackOnly();
return null;
} catch (Exception e) {
ts.setRollbackOnly();
LOGGER.error(e);
return e;
}
}
});
after using #Moles-JWS's answer I am now able to rollback successfully. But I want to handle this only in this method and not change the global configuration of the datasource.
Can I do it here programmatically?
