Error in managing Spring trasaction Declaratively.

Iam trying to use Spring Trasaction manager to declaratively manage my trasactions , but the trasaction is not rolling back as desired on throwing an Exception. The xml file where Iam defining the configurations (test-dao.xml) is as shown below.

<bean id="testDao" class="com.equifax.test.dao.BasicTestDao">
<property name="sessionFactory" ref="testSessionFactory" />
</bean>

</beans>


The Class where Iam testing this Transaction is :

package com.equifax.test.dao;




public class TestSave implements TestSaveInterface{
BasicTestDao dao = (BasicTestDao)SpringContextHolder.ctx().getBean("t estDao");
/**
* @param args
*/
public static void main(String[] args)
{
TestSave tsave = new TestSave();
SavableObject obj1 = new TestObj1();
SavableObject obj2 = new TestObj1();

obj1.setName("Robin");
obj1.setDesignation("Senior Analyst");
tsave.saveRetrieve(obj1, obj2);


}

public void saveRetrieve(SavableObject obj1, SavableObject obj2)
{
TestSave tsave = new TestSave();
tsave.save(obj1);
obj2 = (TestObj1) tsave.retrieve(new Long(23),obj2 );
System.out.println("result"+obj2.getDesignation()) ;

}


public void save(SavableObject obj)
{
dao.save(obj);
new Exception();

}

public Object retrieve(Long id,Object obj)
{
return dao.findById(obj.getClass(), id);
}


}


As can be seend from the test-dao.xml , am defining a pointcut on saveRetrive method, and it can be seen that my advice , defines a rollback on save method when an exception is thrown. The SavableObjcet is getting saved even when the exception is thrown. What is that Iam doing worng , or is itnot the way to implement trasaction management in Spring. any help is appreciated.

thanks in advance!!!
