how to proxy a single class using aop

[muthiahmerchant]

I have a web.xml which does the following

<listener>
        <listener-class>com.common.LoadImage</listener-class>
    </listener>

My LoadImage is something like this

public class LoadImage implements ServletContextListener {
    private ServletContext context = null;

    public void contextDestroyed(ServletContextEvent event) {

    }

    public void contextInitialized(ServletContextEvent event) {
       //some code
    }
}

I have an intercepter that logs messages which states the time take to execute the method.

How do i proxy all methods in this class.

For my beans in applicationContext.xml i use ProxyFactoryBean and it works fine, but this class is not Injected, hence not sure how to proxy it in applicationContext.xml. I would like to do it in applicationContext.xml as I have one version which is solely for finding perf and other version which is for production.

Thanks

DelegatingFilterProxy might be of help.

Thanks for the reply, But DelegateFilterProxy is for filters right, how can i apply this to listeners. Also I have other classes which are not injected by spring and hence don't appear in applicationContext.xml how do I proxy those classes.

Thanks again

Ehm, sorry. Should not try to be helpful after midnight - oh, same time again

I'm not aware of any solution for that particular problem then. Maybe you describe your actual problem a bit that you want to try to solve. Proxying a listener sounds not that useful.

Also I have other classes which are not injected by spring and hence don't appear in applicationContext.xml how do I proxy those classes.

You can still proxy them programmatically.
