I´m using Atomikos with Spring and I´m having problems to update the max_actives.
I´m creating the UserTransactionImp
<bean id="AtomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp">
<property name="transactionTimeout" value="300"/>
</bean>
But I would like to set UserTransactionServiceImp with the config of max_actives
<bean id="atomikosUserTransactionService" class="com.atomikos.icatch.config.UserTransactionServiceImp"
init-method="init" destroy-method="shutdownForce">
<constructor-arg>
<props>
<prop key="com.atomikos.icatch.service">com.atomikos.icatch.standalone.UserTransactionServiceFactory</prop>
<prop key="com.atomikos.icatch.log_base_name">f2e_transactions</prop>
<prop key="com.atomikos.icatch.output_dir">../standalone/log/</prop>
<prop key="com.atomikos.icatch.log_base_dir">../standalone/log/</prop>
<prop key="com.atomikos.icatch.max_actives">1000</prop>
</props>
</constructor-arg>
</bean>
The problem is that it´s seems like UserTransactionImp is creating an instance of UserTransactionService manually.
Any idea how to achieve this in Spring configuration?
private void checkSetup() {
Class var1 = TransactionManagerImp.class;
synchronized(TransactionManagerImp.class) {
this.txmgr_ = TransactionManagerImp.getTransactionManager();
if (this.txmgr_ == null) {
UserTransactionService uts = new UserTransactionServiceImp();
uts.init();
this.txmgr_ = TransactionManagerImp.getTransactionManager();
}
}
}
Regards.
Instead of configuring a UserTransactionServiceImp you can provide a file called transactions.properties at the root of the classpath as described here :

I'm trying to insert data into table using Spring MVC+Hibernate. Table is geting creating but code throwing exception at template.save() method calling in CompanyDao file. Please help to solve this.
I have tested if company object is null but company object having all data but template in null.
File: CompanyDao.java
import org.springframework.orm.hibernate5.HibernateTemplate;
public class CompanyDao {
HibernateTemplate template;
public void setTemplate(HibernateTemplate template) {
this.template = template;
}
//method to save Company
public void saveCompany(Company c){
if(c!=null) {
template.save(c);
}
else {
System.out.print("company object is null");
}
}
}
ApplicationContext.xml

We are currently migrating from xml configuration to complete annotation with java configuration based Spring application. With the annotation approach #Transactional we can achieve but the we need to write for each and every method.
In XML we configured (OLD).
<bean id="txProxyTemplate" abstract="true"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref bean="transactionManager" />
</property>
<property name="transactionAttributes">
<props>
<prop key="delete*">PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED</prop>
<prop key="update*">PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED</prop>
<prop key="save*">PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED</prop>
<prop key="get*">PROPAGATION_SUPPORTS,ISOLATION_READ_COMMITTED,readOnly</prop>
<prop key="is*">PROPAGATION_SUPPORTS,ISOLATION_READ_COMMITTED,readOnly</prop>
<!--<prop key="*">PROPAGATION_REQUIRED</prop> -->
</props>
</property>
</bean>
transactionManager is org.springframework.orm.hibernate3.HibernateTransactionManager
<bean id="xxxxSVC" parent="txProxyTemplate">
<property name="target">
<bean class="XXX.XXX.XXX.SVCImpl">
<property name="xxxxDao" ref="xxxDao"></property>
</bean>
</property>
</bean>
txProxyTemplate is parent class of each service class.
So, please suggest how to configure similar code in java configuration. Thanks for your valuable time spent and support us.

#Bean
public TransactionProxyFactoryBean setTransactionProperties() throws IOException {
TransactionProxyFactoryBean transactionProxyFactoryBean = new TransactionProxyFactoryBean();
transactionProxyFactoryBean.setTransactionManager(transactionManager(sessionFactory()));

}
How to configure with each service implementation class, we can use it for single as a service layer may contain N classes. There is a method setTarget(Object target). Now how can we configure all the N classes. Please sugggest how can we configure.
A sample configuration for this case :
#Bean
public TransactionProxyFactoryBean txProxyTemplate(){
TransactionProxyFactoryBean txFactory=new TransactionProxyFactoryBean();
txFactory.setTransactionManager(new JpaTransactionManager()); // any transcation manager
txFactory.setTransactionAttributes(properties());
return txFactory;
}
#Bean
Properties properties(){
Properties properties=new Properties();
properties.put("delete*", "PROPAGATION_REQUIRED,ISOLATION_READ_COMMITTED");
//set al lthe properties
return properties;
}
#Bean
public TransactionProxyFactoryBean xxxxSVC(TransactionProxyFactoryBean txFactory){
txFactory.setTarget(testEntity());
return txFactory;
}
#Bean
TestEntity testEntity(){
return new TestEntity();
}
We have a scenario where in the catalog/schema combination is different for the entity classes inside certain package from the default one used by all others. I am trying to set Catalog and Schema on #Table annotation using PersistenceUnitPostProcessors callback at runtime using javaassist as below.
The issue: The added member values on javaassist annotation are NOT getting reflected on to the actual class associated with it. Please help me in finding the wrong lines of code; OR if there are other ways to achieve this, more than happy to know.
Note: I do not want to create a separate EntityManagerFactory for each catalog/schema combination - it is not really required in our case as the datasource is same.

Simple answer:
19. Multitenancy
Complex catalog mapping:
interface PhysicalNamingStrategy in Hibernate v5 is helpful.
public interface PhysicalNamingStrategy {
public Identifier toPhysicalCatalogName(Identifier name, JdbcEnvironment jdbcEnvironment);
public Identifier toPhysicalSchemaName(Identifier name, JdbcEnvironment jdbcEnvironment);
....
}
Check the Example 2. Example PhysicalNamingStrategy implementation in Hibernate 5 User Guide and how to config it
Can't get bean from spring container in listener or filter classes.
Have you used something like this :
#Autowired
private ApplicationContext context;
ICustomer customer = (ICustomer) context.getBean("name"); // here name is the name of the bean you want to get context
look I have used this in my project like this ans works well :
String processorName = Introspector.decapitalize(command.getClass().getSimpleName() + "Processor");
ICommandProcessor processor = (ICommandProcessor) context.getBean(processorName);
here if I ll pass command Add then it ll pass processorName = AddProcessor and get it's context.
what is your requirement ? can you post code ?
Look this xml file then check yours from it :
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="packagesToScan" value="com.domain"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.generate_statistics">true</prop>
</props>
</property>
</bean>
<!-- Transaction Manager -->
<bean id="txManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven transaction-manager="txManager" />
here : <property name="packagesToScan" value="com.domain"/> is important when you want to use #Autowired in my project it's com.domain, so refer this and make changes as you need. then again post.
Scenario: In the application I have language-dependent property files which are used as templates to generate emails:
email-subscription_en.properties:
email.subject=You are successfully subscribed to list {0}
email.body=...
email-cancellation_en.properties:
email.subject=You are successfully unsubscribed from list {0}
email.body=...
and so on. Now in Spring context I would like to have these bundles:
<bean id="subscriptionMailProperties" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="org.company.email-subscription" />
</bean>
<bean id="cancellationMailProperties" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="org.company.email-cancellation" />
</bean>
be merged with these common language-independent properties which I would like to be declared in context:
<util:properties id="commonMailProperties">
<prop key="email.from">noreply#company.org</prop>
<prop key="email.to">{0}#company.org</prop>
</util:properties>
How is it possible?
As far as I know there is no support for this. You are trying to mix configuration with resource bundles. I feel what you currently have is right. If you do not have luxury of keeping it as it is, here is a way(more of a hack)
Implement org.springframework.context.MessageSource with 'commonMailProperties'(java.util.Properties) as dependency and say the bean id as 'commonMessageSource'.
In 'getMessage' implementations get the value from 'commonMailProperties'.
Inject 'commonMessageSource' to 'subscriptionMailProperties' and 'cancellationMailProperties', for 'parentMessageSource' property.
If somebody got interested in complete solution:
Create class PropertiesMessageSource:
/**
* {#link org.springframework.context.MessageSource} implementation that resolves messages via underlying
* {#link Properties}.
*/
public class PropertiesMessageSource extends AbstractMessageSource {
private Properties properties;
/**
* Set properties to use.
*/
public void setProperties(Properties properties) {
this.properties = properties;
}
#Override
protected MessageFormat resolveCode(String code, Locale locale) {
String property = properties.getProperty(code);
if (property == null) {
return null;
}
return createMessageFormat(property, locale);
}
}
Use it:
<bean id="commonMailProperties" class="org.company.PropertiesMessageSource">
<property name="properties">
<props>
<prop key="email.from">noreply#company.org</prop>
<prop key="email.to">{0}#company.org</prop>
</props>
</property>
</bean>
<bean id="subscriptionMailProperties" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="org.company.email-subscription" />
<property name="parentMessageSource">
<ref bean="commonMailProperties"/>
</property>
</bean>
ResourceBundleMessageSource (more exactly: all descendants of AbstractMessageSource) now has commonMessages property which can hold locale-independent values. For example while you want to have mail subject and body locale-dependant, some properties (mail from and mail to) are common across all bundles (check SPR-10291):
<bean id="mailProperties" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="org.mycompany.email" />
<property name="commonMessages">
<props>
<prop key="email.from">empty#mydomain.org</prop>
<prop key="email.to">%s#mydomain.org</prop>
</props>
</property>
</bean>
