You are asking for the servlet init parameter, use
getServletContext().getInitParameter() to retrieve the init paramaters for a
context. I found that confusing as well.

Guess you are looking to access the  context param init paramaters  (as
specified in 
context-param blocks).
The  servelt config's getInitParameter corresponds to the *servlet's*
init parameters
So guess you need to use
getServletContext().getInitParameter(applicationName) rather than
getInitParameter(applicationName)

Re: Using init parameters

That sort of works. The applicationName parameter is found now.
However the configDir parameter is not found. This parameter is specified
in
server.xml as follows:

  Context path= docBase=ROOT debug=0
  Parameter name=configDir value=C:\config
override=false/
  /Context

I am sure that this context (the default context) should be used.
