Reading Initialization Parameters
The servlet container provides the initialization parameters for a servlet or filter within the configuration object the container passes to the
init method. The configuration object provides a
getInitParameter() function that takes a
std::string name and returns the contents of the initialization parameter by that name. A filter uses the configuration object to access initialization parameters. A servlet uses the convenience functions provided by
rwsf::GenericServlet to access initialization parameters directly.
The code sample below shows a servlet retrieving the initialization parameters from the
servlet element shown in
Configuration File Example.
std::string greeting = getInitParameter("greeting");
std::string fontsize = getInitParameter("fontsize");
If the instance definition does not contain an initialization parameter with the name provided, the getInitParameter() function returns an empty string.
