Then it probably does not exist.

What exactly do you mean by jspServletConfig ?

You must be thinking of ServletConfig? and wondering how to get the 'config' of a JSP page .... correct?

ServletConfig is mostly helpful because its a way to set/get init parameters for a servlet(s) in your app. To get/set init parameters for a JSP you cam either ...

  • use a scoped attribute (this is mentioned somewhere in the spec) like so ...





  • or use a context init parameter

  • - define the param in the DD and you can retrieve it in your JSP pages with EL like so ...
    - ${initParam.paramname}

    One other point ...

    Its easy to confuse the methods needed to get the init params in servlet code ...

    To get the servlet init params use ...
    To get the context (think application) init params use ...

    Context for context (application) params .... Config for servlet params ...
