Re: Struts2 startup service/action
Ron, this is a great tip! Thanks! I do have one question, though. Any idea how one might go about getting the Spring web context using this method? Normally, I would have extended ContextLoaderServlet. Our experience, so far, has been that it's nearly impossible to get another servlet to play nice with Struts, though. I prefer the method that you've outlined, because it blends well with the Struts environment. I'm just not sure how I can get the context for loading beans. Thoughts?

Re: Struts2 startup service/action
I've been working with ContextLoaderListener for a while this afternoon, but I think I have a problem with dependencies. The latest API docs on Spring indicate that you can get the current web application context from a static method on ContextLoader, but I'm stuck with version 2.0.3 due to dependencies - I think because spring-jpa hasn't caught up. At least, that's my guess from looking at the Maven repository. The end result is that I haven't found a way to get hold of the web application context, yet. Surely, I'm not the only one who needs to do this to initialize some things before the app gets going. I figured someone here would know the secret sauce.

Re: Struts2 startup service/action
I've not used Spring for a while so I can't answer your question directly. But all I'm trying to do is get access to something that would have been correctly initialized had I been under struts. i.e. my QuartzService example was already working under struts, I just wanted to make the scheduler automatically start on startup of the application, rather than having to hit an action. So if you are after something similar do you need to have access to the spring context? I'm not trying to get hold of the Guice injector. Hope this helps Ron -- View this message in context: http://www.nabble.com/Struts2-startup-service-action-tp19738655p19924529.html Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

David C. Hicks [mailto:[EMAIL PROTECTED] wrote I'm stuck with version 2.0.3 due to dependencies - I think because spring-jpa hasn't caught up Looks like spring-jpa has moved to spring-orm in 2.5 org.springframework spring-orm The ContextLoaderListener should work in Spring 2.0.x though. Have you tried WebApplicationContextUtils.getWebApplicationContext(sevletContext) ?

Re: Struts2 startup service/action
I think the more common way is to use a standard ServletContextListener.

QuartzService is an example, it can be any action or service controlled by
the struts objectfactory

Re: Struts2 startup service/action
but this does not give me access to the Guice injector, which is what I
wanted. I think the ServletContextListener would work only if using Spring.
