package com.lesi.lcms3.core;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
public class NewClass extends HttpServlet {
private ServletContext sc;
public String aVer()
{
LiveInfo li = (LiveInfo) sc.getAttribute("live");
return li.getTest();
}
@Override
public void init(ServletConfig config) throws ServletException
{
super.init(config);
sc = config.getServletContext();
}
}
why im getting a null pointer on the sc.getAttribute line?
