Question

I did jar application with Spring 3 TaskScheduler. I run this app with main method:

public static void main(String[] args) {
  GenericXmlApplicationContext ctx = new GenericXmlApplicationContext();
  ctx.load("classpath:scheduler-app-context.xml");
  ctx.refresh();
  while (true) {
    // ...
  }
  // ...
}

Is it please possible run this jar, main method in web application(war file)? How to run this in web.xml.

Many thanks

Do something like this in your web.xml:

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:scheduler-app-context.xml</param-value>
</context-param>

<listener>
   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

This will instantiate your Spring context from the XML file. So it’s not necessary to do this by hand as in your main method.
