I'm sure one of the experts on this list will correct me if I'm wrong, but I
think ServletExec's behavior is correct, and the behavior of the other two
servlet engines is non-standard.
According to the spec, JSP pages created by servlet containers are to
implement the javax.servlet.jsp.HttpJspPage interface. Neither this
interface nor its parent interfaces (javax.servlet.jsp.JspPage and
javax.servlet.Servlet) define the getServletContext() method. Therefore,
invoking getServletContext() within a JSP page is (should be) invalid.
The getServletConfig() method is defined by the javax.servlet.Servlet
interface; therefore, invoking getServletConfig() is standard behavior and
works in all three servlet containers.
An equivalent way of doing what you want instead of using
getServletConfig().getServletContext() is to use the implicit "application"
object:
application.setAttribute("xdbf",adbf);
application.getAttribute("xdbf");
