extending AbstractXmlApplicationContext problem

[bryanhunt]

Hi there,
I'm implementing a class called
ConditionalClassPathXMLApplicationContext it extends
AbstractXmlApplicationContext but allows xml based
configuration of what contexts are loaded.

It is displaying strange behaviour however.

The context is initialized allright, I know this because some of
my beans have initialization methods and they log that they
are initializing, in addition I can see that my hibernate stuff
has initialized ok.

However when I try to access a bean I get a
java.lang.IllegalStateException: Application context not initialized

This is not related but if I can get this working springframwork users will
be able to use configuration like this.... I think this would make things
a lot easier for some projects to maintain + modularise in conjunction
with the PreferencesPlaceholderConfigurer

sorry main should have read as so
snip=
public static void main(String[] args) {

Map mappings = new HashMap();
mappings.put("jestate.unit.testing=enabled","/test/ie/jestate/spring/unit-testing.xml");

Map variables = new HashMap();
variables.put("jestate.unit.testing","enabled");


ConditionalClassPathXMLApplicationContext test = new ConditionalClassPathXMLApplicationContext(mappings ,variables);
BeanFactory beanFactory = (BeanFactory) test;

ISystemUserService systemUserService = (ISystemUserService) test.getBean("SystemUserService");

}
=snip

Everything is working now

[bryanhunt]

but it does the following ....

when loaded in this fashion ...
return new ClassPathXmlApplicationContext("classpath:/ie/jestate/spring/application.xml");

however 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.Pro pertyServiceTest)org.springframework.beans.factory .NoSuchBeanDefinitionException: No bean named 'PropertyService' is defined: org.springframework.beans.factory.support.DefaultL istableBeanFactory defining beans [contextConfigurer]; Root of BeanFactory hierarchy

at test.ie.jestate.spring.service.PropertyServiceTest .setUp(PropertyServiceTest.java:62)
at test.ie.jestate.spring.service.PropertyServiceTest .main(PropertyServiceTest.java:66)


I guess what I am doing wrong here is that my subclass of
AbstractXmlApplicationContext must implement ApplicationContextAware
and then my method is as so ...


/* (non-Javadoc)
* @see org.springframework.context.ApplicationContextAwar e#setApplicationContext(org.springframework.contex t.ApplicationContext)
*/
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {

this.setParent(applicationContext);

refresh();

}

But it has no effect .......

I know I'm nearly there, has anyone got any suggestions ?
