I didn't realize that. The code in SpringObjectFactory looks for
ContextAware and sets it independently and then calls autowire. I
just assumed it did this because the Spring contexts was not
autowired.

I did miss your point as the link you sent as part of this solved the
problem fairly well. I thought you were looking for a different
approach.
I have not used a filter for this in the past as filtering isn't
related to setting the application context in the servlet context. I
have subclassed ContextLoaderListener to accomplish this task. Here
is an example:
public class ApplicationServletContextLoaderListener extends
ContextLoaderListener {
public void contextInitialized(ServletContextEvent event){
super.contextInitialized(event);
ServletContext servletContext = event.getServletContext();
final ApplicationContext ctx =
WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
servletContext.setAttribute("applicationContex",
new AbstractMap(){
ApplicationContext context = ctx;
public Object get(Object key) {
if(key == null){ return null; }
return context.getBean(key.toString());
}
public Set entrySet(){ return Collections.EMPTY_SET; }
}
);
}
}
I do like the ability of the filter to populate a prototype object
from a request and use it in a later jsp. I can see how this could
make simple searches easy. Thanks for posting that.

I have tried to avoid the discussions as to why Spring doesn't just
add the application context to the servlet context without additional
work. This seems to be more of a Spring question than Struts. Most of
the examples I have seen use accessors in a super class to accomplish
what you are doing. I wish I knew why.
I am confused about why doing this in an interceptor would be better
than in the action. If you wish to expose a subset of the Spring
beans, the action solution already does that. If you want to
generally expose the Spring beans to the page, doing it as part of web
app initialization seems like the most convenient approach.

RE: [S2] Accessing objects in the Spring context?
Why not have a base action that has the setters and getters (which extends ActionSupport), put the methods in there, and have all your actions extend that instead of ActionSupport.

Re: [S2] Accessing objects in the Spring context?
Eh, that's the more complicated way... struts2 autowires by name, no
need to implement ApplicationContextAware. I think people are missing
the point.
I got it working just fine by adding 10 properties to my action with
appropriate getters and setters, but I'm trying to sneak around having
to add them to my Actions because I'd rather just have them available
in my JSPs. No big deal I guess because I got it to work by adding the
properties to my Action and they get auto-wired by Spring, but it'd be
REALLY nice if they were available on the context map... it looks like
I can either writer an Interceptor to put the beans on the stack.
Thanks,
James

If it were me, this is what I would do.
First,use a Spring object factory in your Struts configuration:
Second, in your action class, implement
org.springframework.context.ApplicationContextAware:
public void setApplicationContext(ApplicationContext ctx) throws
BeansException {
this.ctx = ctx;
}
Third, implement any getters on the action that your view will need
from the context.
Fourth, define your action in the Spring configuration file:
...
Fifth, test this to see if my memory is as good as I recall.
And lastly, sorry I have not yet introduced myself, I just joined
because I'm converting one of my applications to Struts 2.

Yeah, I was looking for a way around it... these are simple hash maps that are used to display select options. I wound up with an action with 5 Maps in it :( Thanks, James On Tue, Sep 8, 2009 at 4:26 PM, Wes Wannemacher wrote: > You could use the @Autowire annotation directly on a property...

Re: [S2] Accessing objects in the Spring context?
You could use the @Autowire annotation directly on a property... But I don't really see how that is better than using setter-based injection. Just because the beans are singletons doesn't mean anything special, you still need a reference to them in your struts action. -Wes On Tue, Sep 8, 2009 at 5:13 PM, James Carr wrote: > I have several singleton based beans defined in my > applicationContext.xml and I'd like to just use these rather than > being forced to set them on my action. is there any way to accomplish > this? > > Thanks, > James > > - > To unsubscribe, e-mail: user-unsubscr...@struts.apache.org > For additional commands, e-mail: user-h...@struts.apache.org > > -- Wes Wannemacher Head Engineer, WanTii, Inc.

Re: [S2] Accessing objects in the Spring context?
I suppose I may use this: http://wiki.opensymphony.com/display/ABLE/Expose+Spring+Beans+in+JSP But I really wish/hope that struts2 has something built in.
