Reading getServletContext() from static method

Question

Is there any way I can read getServletContext() in a normal static java method? i.e. a class which is not a servlet

My web.xml contains:

<context-param>
    <param-name>paramname</param-name>
    <param-value>test value</param-value>
  </context-param>

and static class:

public classname
{
    public static boolean methodname() 
    {
        String name=javax.servlet.GenericServlet.getServletContext().getInitParameter("paramname");

        // other processing
    }

}

I know I cannot access non-static method from a static class but trying to get a workaround.

I can do this is a servlet class. However my JSP page is calling a static method. Is there any workaround?

You cannot access it magically without first grabbing it at the first time where it is made available by the Servlet API's and then make it available as a static variable via a Util class.

For more places from where you can grab ServletContext check this link.

In the servlet

@Override
public void init(ServletConfig config) {
    ServletContext context = config.getServletContext();
    ServletConfigUtil.config = config;
}

and then you Util class

public class ServletConfigUtil {

public static ServletContext sc = null;

public static ServletContext  getServletContext(){
return sc ;
}
