Subject Re: Servlet init params not being picked up
Date Thu, 01 Feb 2007 01:02:30 GMT
I don't think the init parameters are available via the method you're using
until after  the servlet is initialized. Try using this signature for init

public void init(ServletConfig config) throws ServletException

and then using the getParameterNames method on the ServletConfig object.
