When I test this class using it's main method it works just fine but
when I test it
in this fashion ...
return new ClassPathXmlApplicationContext("classpath:/ie/jestate/spring/app=
lication.xml");

it displays strange behaviour.

The log files show that it is loading the beans as so ...

[@APPNAME@] INFO [main]
HibernateTransactionManager.afterPropertiesSet(231) | Using DataSource
[org.apache.commons.dbcp.BasicDataSource@14275d4] from Hibernate
SessionFactory for HibernateTransactionManager
[@APPNAME@] INFO [main] AbstractBeanFactory.getBean(158) | Creating
shared instance of singleton bean 'myHibernateInterceptor'

NOTE THIS LINE !!!!!!!!!!!!!!!!

[@APPNAME@] INFO [main] AbstractBeanFactory.getBean(158) | Creating
shared instance of singleton bean 'PropertyService'


[@APPNAME@] INFO [main] AbstractBeanFactory.getBean(158) | Creating
shared instance of singleton bean 'PropertyDAO'

But when I try to access them ie "PropertyService" ie get the following
exception ....

) testAddProperty(test.ie.jestate.spring.service.PropertyServiceTest)org.sp=
ringframework.beans.factory.NoSuchBeanDefinitionException:

I am guessing that I have to do something to make it aware of it's
parent but I am't
quite sure what. I'm quite new to spring and haven't found anything obvious=
 in=20
the documentation.

Any help would be much appreciated and I hope that my code can be used in=
=20
the spring framework.
