applicationContext is null

[vammpiro]

hi,

I'm working with OpenAMF/spring/hibernate, using SpringBeanInvoker from the openAMF jar.
when the SpringBeanInvoker tries to get the applicationContext it gets null.
I'm wondering why, I mean, what I need to configure?

private WebApplicationContext context;
context = WebApplicationContextUtils.getWebApplicationContext(
				this.getServletContext());

Can you post your web.xml configuration?

I would guess that OpenAMF is starting up before Spring. You need to configure the servlet startup order using the <load-on-startup> tags such that DispatcherServlet loads first.

I put a listener-class ContextLoaderListener in my web.xml, and the application worked, but I did not understand why yet. could explain?

[robh]

The ContextLoaderListener class is going to load an ApplicationContext and mount it in the ServletContext. This is the AC that is accessed when using WebApplicationContextUtils.

[vammpiro]

the ApplicationContext that I can access from one of my beans of my dispatcherServlet does it not the same that is accessed from WebApplicationContextUtils ?
