Re: [Springframework-developer] DisposableBean / destroy-method -> never gets called

[Juergen H. <ju...@in...>]

Hi Roman,

As we have heard about this rather strange behavior before, ContextLoader
has been reworked for 1.2 RC2: It keeps a reference to the root
WebApplicationContext instance that it creates now, closing exactly that
context instance on shutdown of the web application.

Hence, it doesn't matter anymore whether the ServletContext attribute is
still available when ContextLoaderListener gets called. Arguably, the
Servlet engine should remove the ServletContext attributes *after* calling
all listeners (which all Servlet engines seemed to do) - but we're not
relying on that behavior anymore now.

Please give Spring 1.2 RC2 a try and let me know whether it works for you!

Juergen

never gets called


Hi Spring developers!

I´m using Spring for my current WebApp project and I found a strange
behaviour of Spring.

I´m not sure if I´m doing something wrong or if it´s a bug. So, perhaps you
can take a look at.

First, here is my posting in the Spring forum which describes my problem:
http://forum.springframework.org/viewtopic.php?t=5003

I tried to debug Spring to track the problem down. Here´s what I have:

1. All beans which are implementing the interface DisposableBean are stored
in the map AbstractBeanFactory.disposableBeans. But the method
AbstractBeanFactory.destroySingletons() gets only called for the factory
"-servlet.xml", not for the other two xml files.

2. On shutdown, ContextLoaderListener.contextDestroyed() calls
ContextLoader.closeWebApplicationContext(). But

servletContext.getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTE
XT_ATTRIBUTE);

always returns null. Perhaps the ServletContext is destroyed when the
Listener gets informed? While my app is running,

servletContext.getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTE
XT_ATTRIBUTE);

returns the correct application context.

I´m shutting down my webapp with the url:
http://localhost:8080/manager/stop?path=/mywebapp

My environment:
Tomcat 5.5.7
Java 1.5
Spring 1.2RC1

Please let me know if you need more information.


Best regards,

Roman
