Access ApplicationContext loaded by Listener

[agharta]

Hi,
Anyone known how to load the applicationContext accessing to Listener?

The example: I've a listener that load the application context in web.xml

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
<description>ApplicationContextLoaderListener</description>
<listener-class>org.springframework.web.context.ContextLoade rListener</listener-class>
</listener>

So, what should i do to access to defined beans into applicationcontext by my application?

I don't want to access it by servlet!

Any suggest?

Have a look at WebApplicationContextUtils.getWebApplicationContex t(ServletContext sc)

If can't or don't want to use the servlet context, you could add a "ProxyContextLoaderListener" to your application:

package demo.spring

import javax.servlet.ServletContextEvent;
import org.springframework.web.context.ContextLoader;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.WebApplicationContext;

public class ProxyContextLoaderListener extends ContextLoaderListener {
	private static WebApplicationContext ctx;

	@Override
	public void contextInitialized(ServletContextEvent event) {
		super.contextInitialized(event);
		ctx = ContextLoader.getCurrentWebApplicationContext();
	}

	@Override
	public void contextDestroyed(ServletContextEvent event) {
		super.contextDestroyed(event);
		ctx = null;
	}

	public static WebApplicationContext getCtx() {
		return ctx;
	}
}

The code that needs to access a bean created by ApplicationContext could be as follows:

        ...
        MyClass cl = (MyClass) ProxyContextLoaderListener.getCtx().getBean(
				"myBeanId");
        ...

In the web.xml file you specify the ProxyContextLoaderListener instead of the standard Spring ContextLoaderListener:

     ...
    <listener>
        <listener-class>
        	demo.spring.ProxyContextLoaderListener
        </listener-class>
    </listener>
    ...
