I am looking for a method to easily access the current ApplicationContext that is not bound to j2ee. The closest thing I have found is org.springframework.web.context.ContextLoader.getCurrentWebApplicationContext(), but this class has dependencies on j2ee. Is there a recommended way of obtaining the current ApplicationContext for applications that may exist outside the web? Thanks in advance! Rob |

Hi Robert, Please provide a bit more context about what you're trying to achieve (a simple code example would suffice). - Chris -- Chris Beams Senior Consultant, SpringSource http://www.springsource.com On Jun 10, 2008, at 3:00 PM, Robert Winch wrote: > I am looking for a method to easily access the current > ApplicationContext that is not bound to j2ee.

Thank you for your quick response. I am attempting to easily get instances
out of the "current" ApplicationContext as a factory rather than using IoC.
A few outlines are given below.
1) Here is an example of what I am trying to avoid. I will comment on an
example below (perhaps I am doing this wrong and someone help with that).
// I do not want them to have to know the resources to pass in. This assumes
it is locatorContext.xml, but that can change.
// This flexibility is externalized for a web application using the
contextConfigLocation parameter
BeanFactoryLocator locator =
ContextSingletonBeanFactoryLocator.getInstance("locatorContext.xml");
// Here I need to get a bean factory too? Why is it not just an
ApplicationContext that is returned? Are there benefits to this?
// If there are, I do not like that the user must know the id of the factory
and have that in the code (similar to the resource location, it isn't
externalized)
BeanFactoryReference factoryRef = locator.useBeanFactory("springFactory");
// Get an instance of the object. Here I am not concerned with the user
knowing the id of the bean.
Service service = (Service)factoryRef.getFactory().getBean("service");
Another thing I do not like is that there are so many steps involved in
getting the bean out of the applicationcontext. I just want to get an
instance.
2) One approach I have seen that is similar to what I want is outlined
below:
// get the applicationcontext (but i do not want it to depend on j2ee.
// For example ContextLoader contains a compile time dependency on
ServletContext.
ApplicationContext context =
ContextLoader.getCurrentWebApplicationContext();
// get a bean from the applicationcontext
// once again, knowing the id of the bean is acceptable (and expected)
Service s = (Service) context.getBean("service");
// use the bean
Is there any approach similar to #2 that works without a dependency on j2ee?
I am certain I could write some code to do this, but I would like to do this
with code that exists and in the cleanest way possible. Feedback on even
doing this is appreciated too. I would like to know that part of the
requirement is to use Spring as a Factory (Unfortunately, IoC is not
permissible for this use case).
Thanks!

Robert, Have you considered ApplicationContextAware? http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/context/ApplicationContextAware.html If this is not sufficient for your needs, please post your question below to the community forums at http://forum.springframework.org You'll find this is a more responsive question-and-answer forum than this mailing list which is currently low-traffic and used primarily for announcements. - Chris ----- Original Message ----- From: "Robert Winch" <rw...@gm...> To: spr...@li...

I just wanted to say thank you for your help, guiding me to the correct forum, and tolerance with my poorly worded problem. For those that may be facing a similar problem, I have reworded my question and posted it here http://forum.springframework.org/showthread.php?p=185719 Regards, Rob On Tue, Jun 10, 2008 at 8:25 PM, Chris Beams <chr...@sp...> wrote: > Robert, > > Have you considered ApplicationContextAware? > > > http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/context/ApplicationContextAware.html > > If this is not sufficient for your needs, please post your question below > to the community forums at > > http://forum.springframework.org > > You'll find this is a more responsive question-and-answer forum than this > mailing list which is currently low-traffic and used primarily for > announcements. > > - Chris > > > ----- Original Message ----- > From: "Robert Winch" <rw...@gm...> > To: spr...@li... > Sent: Tuesday, June 10, 2008 5:31:50 PM GMT -05:00 US/Canada Eastern > Subject: Re: [Springframework-developer] Using Spring as a Singleton > Factory? > > > Thank you for your quick response.
