[FIXED] Servlet context attribute from Spring application context

Issue

I'm trying to get rid of really old servlets and add in their place casual services.

Is this possible to get the same data from the application context as I was previously taking from the servlet context?

More specifically, I'm trying to get attribute servletContext.getAttribute("org.directwebremoting.ContainerList") from application context, but ApplicationContext doesn't have getAttribute method.

Solution

Spring uses Servlets as backing technology. So you just need to obtain the ServletContext related to that Servlet and retrieve the attributes.

For the root context, use WebApplicationContext. This interface adds a getServletContext() method to the generic ApplicationContext interface.

Object attribute = webApplicationContext
                .getServletContext()
                .getAttribute("org.directwebremoting.ContainerList");
